This series add initial support for RK3582 support. The RK3582 is a variant of the RK3588S with a few ip blocks disabled. What blocks are disabled/non-working is indicated by the ip-state in OTP.
Compared to the vendor U-Boot variant, this mark cpu and vdec/venc with status=fail instead of removing nodes during DT fixup. Linux skip cpu cores marked as failed staring from v5.17-rc1, however the GIC driver will generate a harmless WARN_ON that safely can be ignored. A patch for Linux will be sent to skip the WARN_ON for failed/disabled cpu cores. It is recommended to use rk3588_ddr_lp4_1848MHz_lp5_2112MHz_v1.19.bin as DRAM init blob RK3582, listed in latest RKBOOT/RK3582MINIALL.ini. Changes in v3: - Apply same policy for RK3582/RK3583 to match vendor U-Boot linux-6.1-stan-rkr6 tag, allow use of the GPU and one vdec core. - Update rkvdec node name to match latest mainling Linux DT patches. - Update commit message to reflect updated policy Changes in v2: - Refactor code to first apply policy to ip-state and then fail cores based on the updated ip-state - Add support for failing rkvdec and rkvenc cores - Append soc compatible to board model - Add patch to add support for ROCK 5C Lite variant Jonas Karlman (3): rockchip: Add initial RK3582 support rockchip: rk3588-generic: Enable support for RK3582 rockchip: rk3588s-rock-5c: Add support for ROCK 5C Lite variant arch/arm/dts/rk3588-generic.dts | 4 +- arch/arm/mach-rockchip/rk3588/Kconfig | 9 +- arch/arm/mach-rockchip/rk3588/rk3588.c | 206 +++++++++++++++++++++++++ configs/generic-rk3588_defconfig | 1 + configs/rock-5c-rk3588s_defconfig | 1 + doc/board/rockchip/rockchip.rst | 4 +- 6 files changed, 217 insertions(+), 8 deletions(-) -- 2.50.1
