From 0d329112c709d6cfedf0fffb19f0cc6b19043f6b Mon Sep 17 00:00:00 2001

Subject: [PATCH] mmc: core: set initial signal voltage on power off
Some boards have SD card connectors where the power rail cannot be switched
off by the driver. If the card has not been power cycled, it may still be
using 1.8V signaling after a warm re-boot. Bootroms expecting 3.3V signaling
will fail to boot from a UHS card that continue to use 1.8V signaling.
Set initial signal voltage in mmc_power_off() to allow re-boot to function.
This fixes re-boot with UHS cards on Asus Tinker Board (Rockchip RK3288),
same issue have been seen on some Rockchip RK3399 boards.
I am sending this as a RFC because I have no insights into SD/MMC subsystem,
this change fix a re-boot issue on my boards and does not break emmc/sdio.
Is this an acceptable workaround? Any advice is appreciated.

Subject: [PATCH] arm64: dts: rockchip: rk356x: Fix PCIe register and
range mappings
The register and range mappings for the PCIe controller in Rockchip's
RK356x SoCs are incorrect. Replace them with corrected values from the
vendor BSP sources, updated to match current DT schema.

USB Host: 1x USB3.0 Type A and 2x USB2.0 on 2.54mm pin header
MicroSD: x 1 for system boot and storage
LED: Power LED x 1, System LED x 1
Key: User Button x 1
Fan: 2 Pin JST ZH 1.5mm Connector for 5V Fan
GPIO: 26 pin-header, include I2C, UART, SPI, I2S, GPIO
Power: 5V/1A, via Type-C or GPIO

This is another shot at previous work submitted by Marty Jones
<mj8263788@gmail.com> (https://lore.kernel.org/linux-arm-kernel/20201228152836.02795e09.mj8263788@gmail.com/),
which is now a year old.
v2: Following up on Robin Murphy's comments, the NEO3 DTS is now
standalone and no longer includes the nanopi R2S one. The lan_led and
wan_len nodes have been removed, and the sys_led node has been renamed
to status_led in accordance with the board schematics.

Subject: [PATCH v2] arm64: dts: rockchip: add more cpu operating points for
RK3328
This allows for greater max frequency on rk3328 boards,
increasing performance.
It has been included in Armbian (a linux distibution for ARM boards)
