- 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

-+ Out of the SoC's many pins only the ones named PAD_GPIO0 to PAD_GPIO63

-+
-+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

-+ * 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.

- 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>

-Convert DT bindings document for Cadence MIPI-CSI2 RX controller to

-
-For compatible, new compatibles should not be messed with conversion,
-but the original binding did not specify any SoC-specific compatible

--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 {
-- remote-endpoint = <&grabber3_in_csi2rx>;
-- };
-- };
-- };
--};

-+================================
-+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:
-+
-+- stf_isp0: is responsible for all the isp operations.
-+- stf_vin0_wr: used to dump RAW images to memory.
-+- stf_vin0_isp0: used to capture images for the stf_vin0_isp0_video1 device.

-
-The QSPI controller needs three reset items to work properly on JH7110 SoC,
-so there is need to change the maxItems's value to 3 and add minItems
-whose value is equal to 2. Other platforms do not have this constraint.

-+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.

-+-----------
-+
-+This driver adds support for reading the built-in temperature sensor on the
-+JH7100 and JH7110 RISC-V SoCs by StarFive Technology Co. Ltd.
-+
-+``sysfs`` interface
-+-------------------
-+
-+The temperature sensor can be enabled, disabled and queried via the standard
-+hwmon interface in sysfs under ``/sys/class/hwmon/hwmonX`` for some value of
-+``X``:

- transmission completion status
-
-The bit DMAC_CHEN[0] is automatically cleared by hardware to disable the
-channel after the last AMBA transfer of the DMA transfer to the
-destination has completed. Software can therefore poll this bit to
-determine when this channel is free for a new DMA transfer.
-This time requires at least 40 milliseconds on JH7110 SoC, otherwise an
-error message 'failed to stop' will be reported.

-
-Currently suspend_save_csrs() and suspend_restore_csrs() functions are
-statically defined in the suspend.c. Change the function's attribute
-to public so that the functions can be used by hibernation as well.

-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:
-- CONFIG_HIBERNATION
-- CONFIG_ARCH_HIBERNATION_HEADER
-- CONFIG_ARCH_HIBERNATION_POSSIBLE

-Subject: [PATCH] clk: starfive: jh7110-sys: Fix lower rate of CPUfreq by
- setting PLL0 rate to 1.5GHz
-
-CPUfreq supports 4 cpu frequency loads on 375/500/750/1500MHz.
-But now PLL0 rate is 1GHz and the cpu frequency loads become
-333/500/500/1000MHz in fact.
-
-So PLL0 rate should be set to 1.5GHz. Change the parent of cpu_root clock
-and the divider of cpu_core before the setting.

-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.

-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.

-
-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.

-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.
