Subject: [PATCH v2 0/2] rtc: add new Amlogic Virtual Wake RTC
Date: Wed, 7 Aug 2019 21:23:55 -0700 [thread overview]
Message-ID: <20190808042357.4663-1-khilman@kernel.org> (raw)
From: Kevin Hilman <khilman@baylibre.com>
Add a new driver for the virtual wake RTC on Amlogic SoCs.
The RTC is virtual from the Linux side because it's a hardware timer
managed by firmware on the secure co-processor (SCP.) The interface
is 1 register where a wakeup time (in seconds) is written. The SCP then
uses this value to program an always-on timer.
Changes since v1:
- add MAINTAINERS entry
- add nop ->alarm_irq_enable() (workaround for RTC core
limitation pointed out by Alexandre Belloni)
- remove unused ->read_alarm()
- fix statics
- move resume to dev_pm_ops
- add suspend hook
- don't calculate (or write) the alarm timer value until suspend time
Changes since Neil's original version
- move from do_gettimeofday() to ktime_get()
