[PATCH 0/4] arm64: qcom: fix the reboot reason handling on sa8775p

Posted by Bartosz Golaszewski 2 years, 8 months ago

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

SA8775P uses nvmem to pass the reboot reason magic value to the bootloader.
Remove the reboot modes from the PON node and introduce an SDAM node passed
to the nvmem-reboot-mode driver. While at it: convert the bindings for
nvmem-reboot-mode to YAML and enable it for arm64 in defconfig.

It looks like it's too late for the dts patches in v6.4, but I was
picking up defconfig patches from the list, and that one seems useful
regardless of the rest, so I added it to the soc/defconfig branch.
