The RP1 driver uses the infrastructure enabled by OF_OVERLAY config option. Enable that option in defconfig in order to produce a kernel usable on RaspberryPi5 avoiding to enable it separately. Signed-off-by: Andrea della Porta <andrea.porta@xxxxxxxx> --- This patch is *OPTIONAL* since I'm not sure if OF_OVERLAY is a desirable feature to have enabled by default. It would be advisable to have it included so that 'make defconfig' can produce a kernel config that will work out of the box on Rpi5, otherwise OF_OVERLAY has to be enabled separately. arch/arm64/configs/defconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/configs/defconfig b/arch/arm64/configs/defconfig index cc70793e97ef..ca492fbd2773 100644 --- a/arch/arm64/configs/defconfig +++ b/arch/arm64/configs/defconfig @@ -1643,6 +1643,7 @@ CONFIG_FPGA_BRIDGE=m CONFIG_ALTERA_FREEZE_BRIDGE=m CONFIG_FPGA_REGION=m CONFIG_OF_FPGA_REGION=m +CONFIG_OF_OVERLAY=y CONFIG_TEE=y CONFIG_OPTEE=y CONFIG_MUX_GPIO=m -- 2.35.3
