This causes a warning for ARCH=arm allmodconfig:
$ make -j"$(nproc)" -s ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- O=out/arm allmodconfig
WARNING: unmet direct dependencies detected for POWER_RESET_VEXPRESS
Depends on [n]: POWER_RESET [=y] && (ARM [=y] || ARM64) && VEXPRESS_CONFIG [=m]=y
Selected by [y]:
- ARCH_VEXPRESS [=y] && ARCH_MULTI_V7 [=y]
and still doesn't fix the error:
arm-linux-gnueabi-ld: drivers/power/reset/vexpress-poweroff.o: in function `vexpress_reset_probe':
vexpress-poweroff.c:(.text+0x36c): undefined reference to `devm_regmap_init_vexpress_config'
Cheers,
