Subject: [PATCH v2 0/4] ARM: at91: pm: add ULP1 mode support
Date: Thu, 4 Feb 2016 15:37:47 +0800 [thread overview]
Message-ID: <1454571471-4434-1-git-send-email-wenyou.yang@atmel.com> (raw)
The ULP1 (Ultra Low-power mode 1) is introduced by SAMA5D2.
In order to achieve the lowest power consumption, in the ULP1 mode,
all the clocks are shut off, inclusive the embedded 12MHz RC oscillator.
The fast startup signal is used as a wake up source for ULP1 mode.
As soon as the wake up event is asserted, the embedded 12MHz RC
oscillator restarts automatically, which fast startup signal
to trigger the PMC to wake up the system from the ULP1 mode can be
configured via DT.
It is based on the following patch set:
http://lists.infradead.org/pipermail/linux-arm-kernel/2015-December/390954.html
Changes in v2:
- fix label pm_exit to ulp_exit.
- shorten the pmc-fast-startup property's name.
- use the value property, instead of bool property for high
or low triggered.
- change the property name and property description.
