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. https://lore.kernel.org/u-boot/258c2dbf-436d-5935-83f5-a2dbb8cf62d7@xxxxxxxxxxxxxx/ 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: https://rockchip.fr/RK312X%20TRM/ rk3128 datasheet: https://rockchip.fr/RK3128%20datasheet%20V1.2.pdf === NOT TESTED WITH HARDWARE NO THERMAL PROTECTION === Request: Review of nodes and pin definitions. Help with testing on hardware. Help with correct "arm,armv7-timer" properties. === Johan Jonker (4): dt-bindings: arm: rockchip: Add Rockchip RK3128 Evaluation board dt-bindings: timer: rockchip: add rockchip,rk3128-timer ARM: dts: rockchip: add rk3128.dtsi ARM: dts: rockchip: add rk3128-evb.dts .../devicetree/bindings/arm/rockchip.yaml | 5 + .../bindings/timer/rockchip,rk-timer.yaml | 1 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/rk3128-evb.dts | 105 ++ arch/arm/boot/dts/rk3128.dtsi | 930 ++++++++++++++++++ 5 files changed, 1042 insertions(+) create mode 100644 arch/arm/boot/dts/rk3128-evb.dts create mode 100644 arch/arm/boot/dts/rk3128.dtsi -- 2.20.1
