Subject: [RFC PATCH 0/3] ARM64: meson-gxbb: Add support for system suspend
Date: Thu, 3 Nov 2016 15:29:22 +0100 [thread overview]
Message-ID: <1478183365-23708-1-git-send-email-narmstrong@baylibre.com> (raw)
Thie patchset is a very experiment patchset to support the System Suspend
feature of the Amlogic Meson GX SoCs.
These SoCs implements system suspend using a non-standard PSCI CPU_SUSPEND
parameter to enter system suspend.
A small driver is added to properly fill the platform_suspend_ops and make
to correct SMC call.
In order to wake up from an alarm, these SoCs have a special memory mapped
register where an alarm time delay in seconds is stored.
In order to reuse the RTC wakealarm feature, implement a fake RTC device
that uses the system time to calculate a delay to write to the register.
Note that this RFC is here to seek a better way to handle these platform
specific features.
