+Subject: [PATCH 003/122] clk: starfive: Replace SOC_STARFIVE with
+ ARCH_STARFIVE
+
+Using ARCH_FOO symbol is preferred than SOC_FOO.
+Set obj-y for starfive/ in Makefile, so the StarFive drivers
+can be compiled with COMPILE_TEST=y but ARCH_STARFIVE=n.

+Subject: [PATCH 004/122] clk: starfive: Factor out common JH7100 and JH7110
+ code
+
+The clock control registers on the StarFive JH7100 and JH7110 work
+identically, so factor out the code then drivers for the two SoCs
+can share it without depending on each other. No functional change.

+Subject: [PATCH 009/122] reset: starfive: Factor out common JH71X0 reset code
+
+The StarFive JH7100 SoC has additional reset controllers for audio and
+video, but the registers follow the same structure. On the JH7110 the
+reset registers don't get their own memory range, but instead follow the
+clock control registers. The registers still follow the same structure
+though, so let's factor out the common code to handle all these cases.

+Subject: [PATCH 012/122] reset: starfive: jh71x0: Use 32bit I/O on 32bit
+ registers
+
+We currently use 64bit I/O on the 32bit registers. This works because
+there are an even number of assert and status registers, so they're only
+ever accessed in pairs on 64bit boundaries.
+
+There are however other reset controllers for audio and video on the
+JH7100 SoC with only one status register that isn't 64bit aligned so
+64bit I/O results in an unaligned access exception.
+
+Switch to 32bit I/O in preparation for supporting these resets too.

+Subject: [PATCH 017/122] clk: starfive: Avoid casting iomem pointers
+
+Let's use a wrapper struct for the auxiliary_device made in
+jh7110_reset_controller_register() so that we can stop casting iomem
+pointers. The casts trip up tools like sparse, and make for some awkward
+casts that are largely unnecessary. While we're here, change the
+allocation from devm and actually free the auxiliary_device memory in
+the release function. This avoids any use after free problems where the
+parent device driver is unbound from the device but the
+auxiliuary_device is still in use accessing devm freed memory.

++ Bindings for the JH7110 RISC-V SoC from StarFive Technology Ltd.
++
++ Out of the SoC's many pins only the ones named PAD_GPIO0 to PAD_GPIO63
++ can be multiplexed and have configurable bias, drive strength,
++ schmitt trigger etc.
++ Some peripherals have their I/O go through the 64 "GPIOs". This also
++ includes a number of other UARTs, I2Cs, SPIs, PWMs etc.
++ All these peripherals are connected to all 64 GPIOs such that
++ any GPIO can be set up to be controlled by any of the peripherals.

++
++description:
++ This PLL are high speed, low jitter frequency synthesizers in JH7110.
++ Each PLL clocks work in integer mode or fraction mode by some dividers,
++ and the configuration registers and dividers are set in several syscon
++ registers. So pll node should be a child of SYS-SYSCON node.
++ The formula for calculating frequency is that,
++ Fvco = Fref * (NI + NF) / M / Q1

++ * StarFive JH7110 PLL Clock Generator Driver

++ * Copyright (C) 2023 StarFive Technology Co., Ltd.
++ *
++ * This driver is about to register JH7110 PLL clock generator and support ops.
++ * The JH7110 have three PLL clock, PLL0, PLL1 and PLL2.
++ * Each PLL clocks work in integer mode or fraction mode by some dividers,
++ * and the configuration registers and dividers are set in several syscon registers.
++ * The formula for calculating frequency is:
++ * Fvco = Fref * (NI + NF) / M / Q1
++ * Fref: OSC source clock rate
++ * NI: integer frequency dividing ratio of feedback divider, set by fbdiv[11:0].
++ * NF: fractional frequency dividing ratio, set by frac[23:0]. NF = frac[23:0] / 2^24 = 0 ~ 0.999.
++ * M: frequency dividing ratio of pre-divider, set by prediv[5:0].
++ * Q1: frequency dividing ratio of post divider, set by postdiv1[1:0], Q1= 1,2,4,8.

+
+According to:

+stmmac_main.c: stmmac_dvr_probe
+
+dwmac controller may require one (stmmaceth) or two (stmmaceth+ahb)

+
+The gmac of Starfive Jh7110 SOC must have two resets.
+it uses snps,dwmac-5.20 IP.

+Subject: [PATCH 045/122] net: stmmac: dwmac-starfive: Add phy interface
+ settings
+
+dwmac supports multiple modess. When working under rmii and rgmii,
+you need to set different phy interfaces.
+
+According to the dwmac document, when working in rmii, it needs to be
+set to 0x4, and rgmii needs to be set to 0x1.
+
+The phy interface needs to be set in syscon, the format is as follows:
+starfive,syscon: <&syscon, offset, shift>

+-Cadence MIPI-CSI2 RX controller
+-===============================
+-
+-The Cadence MIPI-CSI2 RX controller is a CSI-2 bridge supporting up to 4 CSI
+-lanes in input, and 4 different pixel streams in output.
+-
+-Required properties:
+- - compatible: must be set to "cdns,csi2rx" and an SoC-specific compatible
+- - reg: base address and size of the memory mapped region
+- - clocks: phandles to the clocks driving the controller
+- - clock-names: must contain:
+- * sys_clk: main clock
+- * p_clk: register bank clock
+- * pixel_if[0-3]_clk: pixel stream output clock, one for each stream
+- implemented in hardware, between 0 and 3
+-
+-Optional properties:
+- - phys: phandle to the external D-PHY, phy-names must be provided
+- - phy-names: must contain "dphy", if the implementation uses an
+- external D-PHY
+-
+-Required subnodes:
+- - ports: A ports node with one port child node per device input and output
+- port, in accordance with the video interface bindings defined in
+- Documentation/devicetree/bindings/media/video-interfaces.txt. The
+- port nodes are numbered as follows:
+-
+- Port Description
+- -----------------------------
+- 0 CSI-2 input
+- 1 Stream 0 output
+- 2 Stream 1 output
+- 3 Stream 2 output
+- 4 Stream 3 output
+-
+- The stream output port nodes are optional if they are not
+- connected to anything at the hardware level or implemented
+- in the design.Since there is only one endpoint per port,
+- the endpoints are not numbered.
+-
+-
+-Example:
+-
+-csi2rx: csi-bridge@0d060000 {
+- compatible = "cdns,csi2rx";
+- reg = <0x0d060000 0x1000>;
+- clocks = <&byteclock>, <&byteclock>
+- <&coreclock>, <&coreclock>,
+- <&coreclock>, <&coreclock>;
+- clock-names = "sys_clk", "p_clk",
+- "pixel_if0_clk", "pixel_if1_clk",
+- "pixel_if2_clk", "pixel_if3_clk";
+-
+- ports {
+- #address-cells = <1>;
+- #size-cells = <0>;
+-
+- port@0 {
+- reg = <0>;
+-
+- csi2rx_in_sensor: endpoint {
+- remote-endpoint = <&sensor_out_csi2rx>;
+- clock-lanes = <0>;
+- data-lanes = <1 2>;
+- };
+- };
+-
+- port@1 {
+- reg = <1>;
+-
+- csi2rx_out_grabber0: endpoint {
+- remote-endpoint = <&grabber0_in_csi2rx>;
+- };
+- };
+-
+- port@2 {
+- reg = <2>;
+-
+- csi2rx_out_grabber1: endpoint {
+- remote-endpoint = <&grabber1_in_csi2rx>;
+- };
+- };
+-
+- port@3 {
+- reg = <3>;
+-
+- csi2rx_out_grabber2: endpoint {
+- remote-endpoint = <&grabber2_in_csi2rx>;
+- };
+- };
+-
+- port@4 {
+- reg = <4>;
+-
+- csi2rx_out_grabber3: endpoint {

++================================
++Starfive Camera Subsystem driver
++================================
++
++Introduction
++------------
++
++This file documents the driver for the Starfive Camera Subsystem found on
++Starfive JH7110 SoC. The driver is located under drivers/media/platform/
++starfive.
++
++The driver implements V4L2, Media controller and v4l2_subdev interfaces.
++Camera sensor using V4L2 subdev interface in the kernel is supported.
++
++The driver has been successfully used on the Gstreamer 1.18.5 with
++v4l2src plugin.
++
++
++Starfive Camera Subsystem hardware
++----------------------------------
++
++The Starfive Camera Subsystem hardware consists of:
++
++- MIPI DPHY Receiver: receives mipi data from a MIPI camera sensor.
++- MIPI CSIRx Controller: is responsible for handling and decoding CSI2 protocol
++ based camera sensor data stream.
++- ISP: handles the image data streams from the MIPI CSIRx Controller.
++- VIN(Video In): a top-level module, is responsible for controlling power
++ and clocks to other modules, dumps the input data to memory or transfers the
++ input data to ISP.
++
++
++Topology
++--------
++
++The media controller pipeline graph is as follows:
++
++.. _starfive_camss_graph:
++
++.. kernel-figure:: starfive_camss_graph.dot
++ :alt: starfive_camss_graph.dot
++ :align: center
++
++The driver has 2 video devices:
++
++- stf_vin0_wr_video0: capture device for images directly from the VIN module.
++- stf_vin0_isp0_video1: capture device for images without scaling.
++
++The driver has 3 subdevices:
++

+The QSPI controller needs three reset items to work properly on JH7110 SoC,

++## JH7110 Upstream Status ##
++
++To get the latest status of each upstreaming patch series, please visit
++our RVspace.
++
++https://rvspace.org/en/project/JH7110_Upstream_Plan
++
++## Build Instructions ##
++
++1. Configure Kconfig options
++
++```shell
++# Use default selections
++make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- defconfig
++```
++
++or
++
++```shell
++# Select options manually
++make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- nconfig
++```
++
++To boot up the VisionFive 2 board, please make sure **SOC_STARFIVE**,
++**CLK_STARFIVE_JH7110_SYS**, **PINCTRL_STARFIVE_JH7110_SYS**,
++**SERIAL_8250_DW** are selected.
++> If you need MMC and GMAC drivers, you should also select
++**MMC_DW_STARFIVE** and **DWMAC_STARFIVE**.
++
++2. Build
++```shell
++make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu-
++```
++
++## How to Run on VisionFive 2 Board via Network ##
++
++1. Power on, enter u-boot and set enviroment parameters
++```
++setenv fdt_high 0xffffffffffffffff; setenv initrd_high 0xffffffffffffffff;
++setenv scriptaddr 0x88100000; setenv script_offset_f 0x1fff000; setenv script_size_f 0x1000;
++setenv kernel_addr_r 0x84000000; setenv kernel_comp_addr_r 0x90000000; setenv kernel_comp_size 0x10000000;
++setenv fdt_addr_r 0x88000000; setenv ramdisk_addr_r 0x88300000;
++```
++2. Set IP addresses for the board and your tftp server
++```
++setenv serverip 192.168.w.x; setenv gatewayip 192.168.w.y; setenv ipaddr 192.168.w.z; setenv hostname starfive; setenv netdev eth0;
++```
++3. Upload dtb, image and file system to DDR from your tftp server
++```
++tftpboot ${fdt_addr_r} jh7110-starfive-visionfive-2-v1.3b.dtb; tftpboot ${kernel_addr_r} Image.gz; tftpboot ${ramdisk_addr_r} initramfs.cpio.gz;
++```
++> If your VisionFive 2 is v1.2A, you should upload jh7110-starfive-visionfive-2-v1.2a.dtb instead.
++4. Load and boot the kernel
++```
++booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
++```
++When you see the message "buildroot login:", the launch was successful.
++You can just input the following accout and password, then continue.
++```
++buildroot login: root
++Password: starfive
++```

++description:
++ The JH7100 and JH7110 watchdog both are 32 bit counters. JH7100 watchdog
++ has only one timeout phase and reboots. And JH7110 watchdog has two
++ timeout phases. At the first phase, the signal of watchdog interrupt
++ output(WDOGINT) will rise when counter is 0. The counter will reload
++ the timeout value. And then, if counter decreases to 0 again and WDOGINT
++ isn't cleared, the watchdog will reset the system unless the watchdog
++ reset is disabled.

+
+The DMA controller needs two reset items to work properly on JH7110 SoC,
+so there is need to constrain the items' value to 2, other platforms
+have 1 reset item at most.

+The bit DMAC_CHEN[0] is automatically cleared by hardware to disable the

+determine when this channel is free for a new DMA transfer.

+Subject: [PATCH 116/122] RISC-V: Add arch functions to support
+ hibernation/suspend-to-disk
+
+Low level Arch functions were created to support hibernation.
+swsusp_arch_suspend() relies code from __cpu_suspend_enter() to write
+cpu state onto the stack, then calling swsusp_save() to save the memory
+image.
+
+Arch specific hibernation header is implemented and is utilized by the
+arch_hibernation_header_restore() and arch_hibernation_header_save()
+functions. The arch specific hibernation header consists of satp, hartid,
+and the cpu_resume address. The kernel built version is also need to be
+saved into the hibernation image header to making sure only the same
+kernel is restore when resume.
+
+swsusp_arch_resume() creates a temporary page table that covering only
+the linear map. It copies the restore code to a 'safe' page, then start
+to restore the memory image. Once completed, it restores the original
+kernel's page table. It then calls into __hibernate_cpu_resume()
+to restore the CPU context. Finally, it follows the normal hibernation
+path back to the hibernation core.
+
+To enable hibernation/suspend to disk into RISCV, the below config
+need to be enabled:

+
+This adds a compatible for the high speed UARTs on the StarFive JH7100
+RISC-V SoC. Just like the regular uarts we also need to keep the input
+clocks at their default rate and rely only on the divisor in the UART.

+
+To improve human readability and enable automatic validation, the tuples

+grouped.
+
+Fix this by grouping the tuples of "interrupts-extended" properties

+Subject: [PATCH 1009/1024] pinctrl: starfive: Reset pinmux settings
+
+Current u-boot doesn't seem to take into account that some GPIOs are
+configured as inputs/outputs of certain peripherals on power-up. This
+means it ends up configuring some GPIOs as inputs to more than one
+peripheral which the documentation explicitly says is illegal. Similarly
+it also ends up configuring more than one GPIO as output of the same
+peripheral. While not explicitly mentioned by the documentation this
+also seems like a bad idea.
+
+The easiest way to remedy this mess is to just disconnect all GPIOs from
+peripherals and have our pinmux configuration set everything up
+properly. This, however, means that we'd disconnect the serial console
+from its pins for a while, so add a device tree property to keep
+certain GPIOs from being reset.

+Subject: [PATCH 1010/1024] clk: starfive: Add flags argument to JH71X0__MUX
+ macro
+
+This flag is needed to add the CLK_SET_RATE_PARENT flag on the gmac_tx
+clock on the JH7100, which in turn is needed by the dwmac-starfive
+driver to set the clock properly for 1000, 100 and 10 Mbps links.
+
+This change was mostly made using coccinelle:
+
+@ match @
+expression idx, name, nparents;

+ JH71X0__MUX(
+-idx, name, nparents,
++idx, name, 0, nparents,
+ ...)

+
+This adds support for the StarFive JH7100 and JH7110 SoCs which also
+feature this SiFive cache controller.
+
+Unfortunately the interrupt for uncorrected data is broken on the JH7100
+and fires continuously, so add a quirk to not register a handler for it.

+Subject: [PATCH 1022/1024] reset: starfive: Add JH7100 audio reset driver
+
+The audio resets are almost identical to the system resets, there are
+just fewer of them. So factor out and export a generic probe function,
+so most of the reset controller implementation can be shared.
