Hi Krzysztof,
This series adds support for syscon-reboot and syscon-poweroff to gs101/Oriole.
It has been tested with reboot and poweroff commands respectively.
Note the syscon-reboot/poweroff has *runtime* dependencies on the exynos-pmu
and clk-gs101 patches in this series, as well as [1] which was just queued by
Lee. As you are the maintainer for exynos-pmu and samsung clock drivers I've
included those patches in this series.
For the moment I have left out syscon-reboot-mode dt node as whilst it uses the
same SYSIP_DAT0 register as exynosautov9, and setting this the reboot mode is
correctly reported in the Pixel bootloader. The bootloader is also checking a
scratch register in max77779 chip that isn't currently enabled upstream, and
thus the bootloader doesn't actually enter fastboot.
Kind regards,
Peter
