Subject: [PATCH v2 0/4] Add basic Rockchip rk3128 DT support
Date: Fri, 28 Oct 2022 16:39:04 +0200 [thread overview]
Message-ID: <e83964fe-ad87-0905-4586-e235757c6b2b@gmail.com> (raw)
Add basic Rockchip rk3128 DT support.
Features:
Quad-core ARM Cortex-A7MP Core processor
Clock & reset unit
Power management unit
Interrupt controller
DMAC
6x 64 bits Timers
4x PWMs
1x 32 bits watchdog
Internal memory:
Internal BootRom
Internal SRAM 8KB
External memory:
Dynamic Memory Interface (DDR3/DDR3L/LPDDR2)
Nand Flash Interface
eMMC Interface
SD/MMC Interface
Connectivity:
SDIO interface
SPI Controller
3x UART controller
4x I2C controllers
4x groups of GPIO (GPIO0~GPIO3), 32 GPIOs per group
USB Host2.0
USB OTG2.0

The Linux kernel has added a rk3128 clock driver in the past,
but the DT is still missing.
In U-boot the rk3128 DT doesn't conform the latest bindings
and also the pin definition don't match the TRM.
On request from the U-boot maintainers I submit a basic rk3128 DT.

Based on:
https://source.denx.de/u-boot/u-boot/-/blob/master/arch/arm/dts/rk3128.dtsi
https://github.com/rockchip-linux/kernel/blob/develop-4.4/arch/arm/boot/dts/rk312x.dtsi
rk3128 TRM:

rk3128 datasheet:
https://rockchip.fr/RK3128%20datasheet%20V1.2.pdf
===
NOT TESTED WITH HARDWARE
NO THERMAL PROTECTION
===
Request:
Help with testing on hardware.
===
Changed V2:
rk3128.dtsi:
remove aliases
add gic interrupts mask defines
add virtual timer interrupts
rk3128-evb.dts:
use generic node names
remove underscores in node names
add more aliases
sort
