From 3f9ef7785a9cd69cb75f5e2ea4ca79a24752e496 Mon Sep 17 00:00:00 2001

Date: Wed, 3 Feb 2021 10:21:41 +0100
Subject: MIPS: ralink: manage low reset lines
Reset lines with indices smaller than 8 are currently considered invalid
by the rt2880-reset reset controller.
The MT7621 SoC uses a number of these low reset lines. The DTS defines
reset lines "hsdma", "fe", and "mcm" with respective values 5, 6, and 2.
As a result of the above restriction, these resets cannot be asserted or
de-asserted by the reset controller. In cases where the bootloader does
not de-assert these lines, this results in e.g. the MT7621's internal
switch staying in reset.
Change the reset controller to only ignore the system reset, so all
reset lines with index greater than 0 are considered valid.

From: Tobias Wolf <dev-NTEO@vplace.de>
Subject: [v2] MIPS: Fix memory reservation in bootmem_init for certain non-usermem setups
Commit 67a3ba25aa95 ("MIPS: Fix incorrect mem=X@Y handling") introduced a new
issue for rt288x where "PHYS_OFFSET" is 0x0 but the calculated "ramstart" is
not. As the prerequisite of custom memory map has been removed, this results
in the full memory range of 0x0 - 0x8000000 to be marked as reserved for this
platform.
v2: Correctly compare that usermem is not null.
This patch adds the originally intended prerequisite again.

Subject: [PATCH] MIPS: add bootargs-override property
Add support for the bootargs-override property to the chosen node
similar to the one used on ipq806x or mpc85xx.
This is necessary, as the U-Boot used on some boards, notably the
Ubiquiti UniFi 6 Lite, overwrite the bootargs property of the chosen
node leading to a kernel panic when loading OpenWrt.

There is a variant of MT7621 which contains only one CPU core instead of 2.
This is not reflected in the config register, so the kernel detects more
physical cores, which leads to a hang on SMP bringup.
Add a hack to detect missing cores.

Date: Wed, 10 Jul 2019 00:24:48 +0800
Subject: [PATCH] MIPS: ralink: mt7621: add memory detection support
mt7621 has the following memory map:
0x0-0x1c000000: lower 448m memory
0x1c000000-0x2000000: peripheral registers
0x20000000-0x2400000: higher 64m memory
detect_memory_region in arch/mips/kernel/setup.c only add the first
memory region and isn't suitable for 512m memory detection because
it may accidentally read the memory area for peripheral registers.
This commit adds memory detection capability for mt7621:
1. add the highmem area when 512m is detected.
2. guard memcmp from accessing peripheral registers:
This only happens when some weird user decided to change
kernel load address to 256m or higher address. Since this
is a quite unusual case, we just skip 512m testing and return
256m as memory size.

This reverts commit a307593a644443db12888f45eed0dafb5869e2cc.
This brings back the do_carrier flags used by the (hacky) next patch,
still required by target/linux/ramips/files/drivers/net/ethernet/ralink/mdio.c

+Ralink SoC GPIO controller bindings
+
+Required properties:
+- compatible:
+ - "ralink,rt2880-gpio" for Ralink controllers
+- #gpio-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify optional parameters (unused)
+- gpio-controller : Marks the device node as a GPIO controller
+- reg : Physical base address and length of the controller's registers
+- interrupt-parent: phandle to the INTC device node
+- interrupts : Specify the INTC interrupt number
+- ralink,num-gpios : Specify the number of GPIOs
+- ralink,register-map : The register layout depends on the GPIO bank and actual
+ SoC type. Register offsets need to be in this order.
+ [ INT, EDGE, RENA, FENA, DATA, DIR, POL, SET, RESET, TOGGLE ]
+
+Optional properties:
+- ralink,gpio-base : Specify the GPIO chips base number
+
+Example:
+
+ gpio0: gpio@600 {
+ compatible = "ralink,rt5350-gpio", "ralink,rt2880-gpio";
+
+ #gpio-cells = <2>;
+ gpio-controller;
+
+ reg = <0x600 0x34>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <6>;
+
+ ralink,gpio-base = <0>;
+ ralink,num-gpios = <24>;
+ ralink,register-map = [ 00 04 08 0c
+ 20 24 28 2c
+ 30 34 ];

Subject: [PATCH 27/53] GPIO: MIPS: ralink: add gpio driver for ralink SoC
Add gpio driver for Ralink SoC. This driver makes the gpio core on
RT2880, RT305x, rt3352, rt3662, rt3883, rt5350 and mt7620 work.

+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.

+I2C for Ralink platforms
+
+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
+
+Example :
+
+palmbus@10000000 {
