[PATCH 0/3] arm64: meson: add support for A1 Power Domains

[Jianxin Pan]

This patchset introduces a "Secure Power Doamin Controller". In A1/C1, power
controller registers such as PWRCTRL_FOCRSTN, PWRCTRL_PWR_OFF, PWRCTRL_MEM_PD
and PWRCTRL_ISO_EN, are in the secure domain, and should be accessed from ATF
by smc.

This patchset is based on A1 DTB series at [0].
