-
-Shifting a value (131032) larger than the type (32 bit unsigned integer)
-is undefined behaviour in C.
-
-The problem is in 'mt7621_gate_is_enabled()' function which is using the
-'BIT()' kernel macro with the bit index for the clock gate to check if the
-bit is set. When the clock gates structure is created driver is already
-setting 'bit_idx' using 'BIT()' macro, so we are wrongly applying an extra
-'BIT()' mask here. Removing it solve the problem and makes this function
-correct. However when clock gating is correctly working, the kernel starts
-disabling those clocks that are not requested. Some drivers for this SoC
-are older than this clock driver itself. So to avoid the kernel to disable
-clocks that have been enabled until now, we must apply 'CLK_IS_CRITICAL'
-flag on gates initialization code.

-Subject: [PATCH 2/9] clk: ralink: add clock and reset driver for MTMIPS SoCs
-
-Until now, clock related code for old ralink SoCs was based in fixed clocks
-using 'clk_register_fixed_rate' and 'clkdev_create' directly doing in code
-and not using device tree at all for their definition. Including this driver
-is an effort to be able to define proper clocks using device tree and also
-cleaning all the clock and reset related code from 'arch/mips/ralink' dir.
-This clock and reset driver covers all the ralink SoCs but MT7621 which is
-the newest and provides gating and some differences that make it different
-from its predecesors. It has its own driver since some time ago. The ralink
-SoCs we are taking about are RT2880, RT3050, RT3052, RT3350, RT3352, RT3883,
-RT5350, MT7620, MT7628 and MT7688. Mostly the code in this new driver has
-been extracted from 'arch/mips/ralink' and cleanly put using kernel clock
-driver APIs. The clock plans for this SoCs only talks about relation between
-CPU frequency and BUS frequency. This relation is different depending on the
-particular SoC. CPU clock is derived from XTAL frequencies.
-
-Depending on the SoC we have the following frequencies:
-* RT2880 SoC:
- - XTAL: 40 MHz.
- - CPU: 250, 266, 280 or 300 MHz.
- - BUS: CPU / 2 MHz.
-* RT3050, RT3052, RT3350:
- - XTAL: 40 MHz.
- - CPU: 320 or 384 MHz.
- - BUS: CPU / 3 MHz.
-* RT3352:
- - XTAL: 40 MHz.
- - CPU: 384 or 400 MHz.
- - BUS: CPU / 3 MHz.
- - PERIPH: 40 MHz.
-* RT3383:
- - XTAL: 40 MHz.
- - CPU: 250, 384, 480 or 500 MHz.
- - BUS: Depends on RAM Type and CPU:
- + RAM DDR2: 125. ELSE 83 MHz.
- + RAM DDR2: 128. ELSE 96 MHz.
- + RAM DDR2: 160. ELSE 120 MHz.
- + RAM DDR2: 166. ELSE 125 MHz.
-* RT5350:
- - XTAL: 40 MHz.
- - CPU: 300, 320 or 360 MHz.
- - BUS: CPU / 3, CPU / 4, CPU / 3 MHz.
- - PERIPH: 40 MHz.
-* MT7628 and MT7688:
- - XTAL: 20 MHz or 40 MHz.
- - CPU: 575 or 580 MHz.
- - BUS: CPU / 3.
- - PCMI2S: 480 MHz.
- - PERIPH: 40 MHz.
-* MT7620:
- - XTAL: 20 MHz or 40 MHz.
- - PLL: XTAL, 480, 600 MHz.
- - CPU: depends on PLL and some mult and dividers.
- - BUS: depends on PLL and some mult and dividers.
- - PERIPH: 40 or XTAL MHz.
-
-MT7620 is a bit more complex deriving CPU clock from a PLL and an bunch of
-register reads and predividers. To derive CPU and BUS frequencies in the
-MT7620 SoC 'mt7620_calc_rate()' helper is used.
-
-In the case XTAL can have different frequencies and we need a different
-clock frequency for peripherals 'periph' clock in introduced.
-
-The rest of the peripherals present in the SoC just follow their parent
-frequencies.
-
-With this information the clk driver will provide all the clock and reset
-functionality from a set of hardcoded clocks allowing to define a nice
-device tree without fixed clocks.

-
-A proper clock driver for ralink SoCs has been added. Hence there is no
-need to have clock related code in 'arch/mips/ralink' folder anymore.
-Since this is the last clock related code removal, remove also remaining
-prototypes in 'common.h' header file.

-Subject: [PATCH 7/9] mips: ralink: remove reset related code
-
-A proper clock driver for ralink SoCs has been added. This driver is also
-a reset provider for the SoC. Hence there is no need to have reset related
-code in 'arch/mips/ralink' folder anymore. The only code that remains is
-the one related with mips_reboot_setup where a PCI reset is performed.
-We maintain this because I cannot test old ralink board with PCI to be
-sure all works if we remove also this code.

-Subject: [PATCH 8/9] mips: ralink: get cpu rate from new driver code
-
-At very early stage on boot, there is a need to set 'mips_hpt_frequency'.
-This timer frequency is a half of the CPU frequency. To get clocks properly
-set we need to call to 'of_clk_init()' and properly get cpu clock frequency
-afterwards. Depending on the SoC, CPU clock index and compatible differs, so
-use them to get the proper clock frm the clock provider. Hence, adapt code
-to be aligned with new clock driver.

-Subject: [PATCH] mips: ralink: introduce commonly used remap node function
-
-The ralink_of_remap() function is repeated several times on SoC specific
-source files. They have the same structure, but just differ in compatible
-strings. In order to make commonly use of these codes, this patch
-introduces a newly designed mtmips_of_remap_node() function to match and
-remap all supported system controller and memory controller nodes.
-
-Build and run tested on MT7620 and MT7628.

-Subject: mips: ralink: match all supported system controller compatible
- strings
-
-Recently, A new clock and reset controller driver has been introduced to
-the ralink mips target[1]. It provides proper system control and adds more
-SoC specific compatible strings. In order to better initialize CPUs, this
-patch removes the outdated "ralink,mt7620a-sysc" and add all dt-binding
-documented compatible strings to the system controller match table.

-Subject: [PATCH 2/2] watchdog: mt7621-wdt: avoid ralink architecture dependent code
-
-MT7621 SoC has a system controller node. Watchdog need to access to reset
-status register. Ralink architecture and related driver are old and from
-the beggining they are using some architecture dependent operations for
-accessing this shared registers through 'asm/mach-ralink/ralink_regs.h'
-header file. However this is not ideal from a driver perspective which can
-just access to the system controller registers in an arch independent way
-using regmap syscon APIs. Update Kconfig accordingly to select new added
-dependencies and allow driver to be compile tested.

-Subject: [PATCH] MIPS: add support for buggy MT7621S core detection
-
-Most MT7621 SoCs have 2 cores, which is detected and supported properly
-by CPS.
-
-Unfortunately, MT7621 SoC has a less common S variant with only one core.
-On MT7621S, GCR_CONFIG still reports 2 cores, which leads to hangs when
-starting SMP. CPULAUNCH registers can be used in that case to detect the
-absence of the second core and override the GCR_CONFIG PCORES field.
-
-Rework a long-standing OpenWrt patch to override the value of
-mips_cps_numcores on single-core MT7621 systems.
-
-Tested on a dual-core MT7621 device (Ubiquiti ER-X) and a single-core
-MT7621 device (Netgear R6220).
-
-Original 4.14 OpenWrt patch:
-Link: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=4cdbc90a376dd0555201c1434a2081e055e9ceb7

-removed the mt7621-dma driver. Move the driver from staging to the

-driver implementations and maintain it downstream in OpenWrt.
-
-This patch will not be sent to upstream linux. It is just a workaround.

-Subject: [PATCH v5 1/2] pinctrl: Add driver for Awinic AW9523/B I2C GPIO
- Expander
-Date: Mon, 25 Jan 2021 19:22:18 +0100
-
-The Awinic AW9523(B) is a multi-function I2C gpio expander in a
-TQFN-24L package, featuring PWM (max 37mA per pin, or total max
-power 3.2Watts) for LED driving capability.
-
-It has two ports with 8 pins per port (for a total of 16 pins),
-configurable as either PWM with 1/256 stepping or GPIO input/output,
-1.8V logic input; each GPIO can be configured as input or output
-independently from each other.
-
-This IC also has an internal interrupt controller, which is capable
-of generating an interrupt for each GPIO, depending on the
-configuration, and will raise an interrupt on the INTN pin to
-advertise this to an external interrupt controller.

-+Ralink SoC RT2880 SPI master controller.
-+
-+This SPI controller is found on most wireless SoCs made by ralink.
-+
-+Required properties:
-+- compatible : "ralink,rt2880-spi"
-+- reg : The register base for the controller.
-+- #address-cells : <1>, as required by generic SPI binding.
-+- #size-cells : <0>, also as required by generic SPI binding.
-+
-+Child nodes as per the generic SPI binding.
-+
-+Example:
-+
-+ spi@b00 {
-+ compatible = "ralink,rt2880-spi";
-+ reg = <0xb00 0x100>;
-+
-+ #address-cells = <1>;
-+ #size-cells = <0>;
-+
-+ m25p80@0 {
-+ compatible = "m25p80";
-+ reg = <0>;
-+ spi-max-frequency = <10000000>;
-+ };
-+ };

-+Required properties :
-+- compatible : Must be "link,rt3052-i2c"
-+- reg: physical base address of the controller and length of memory mapped
-+ region.
-+- #address-cells = <1>;
-+- #size-cells = <0>;
-+
-+Optional properties:
-+- Child nodes conforming to i2c bus binding
