Subject: [PATCH v4 0/4] arm64: meson: add support for A1 Power Domains
Date: Mon, 4 Nov 2019 19:47:04 +0800 [thread overview]
Message-ID: <1572868028-73076-1-git-send-email-jianxin.pan@amlogic.com> (raw)
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.
Changes since v3 at [2]:
- remove phandle to secure-monitor node
Changes since v2 at [1]:
- update domain id
- include dt-bindings in dts
Changes since v1 at [0]:
- use APIs from sm driver
- rename pwrc_secure_get_power as Kevin suggested
- add comments for always on domains
- replace arch_initcall_sync with builtin_platform_driver
- fix coding style
