The mtk-scp driver relies on the existence of the `cros-ec-rpmsg` node in the dt to determine if the SCP is single or multicore. Without patch 2 the driver wrongly assumes the SCP on MT8192 and MT8183 are multicore, leading to the following errors during initialization: >> >> 10696 04:33:59.126671 <3>[ 15.465714] platform 10500000.scp:cros-ec: invalid resource (null) >> 10697 04:33:59.142855 <3>[ 15.478560] platform 10500000.scp:cros-ec: Failed to parse and map sram memory >> 10698 04:33:59.149650 <3>[ 15.486121] mtk-scp 10500000.scp: Failed to initialize core 0 rproc >> >> The issue was caught by KernelCI, complete logs can be found here: >> - asurada: https://storage.kernelci.org/next/master/next-20230914/arm64/defconfig+arm64-chromebook+videodec/gcc-10/lab-collabora/baseline-nfs-mt8192-asurada-spherion-r0.html >> - kukui: https://storage.kernelci.org/next/master/next-20230914/arm64/defconfig+arm64-chromebook+videodec/gcc-10/lab-collabora/baseline-nfs-mt8183-kukui-jacuzzi-juniper-sku16.html >> >> Reporting the issue so that patch 2 and 14 can be resent and merged soon. >> > > Apologies for the trouble here, the error is mine. > > I have applied and pushed patch 02 - please confirm that things are working as > expected now.
