From: Kevin Hilman <khilman@xxxxxxxxxxxx> 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 v2: - switch to devm_platform_ioremap_resource() - switch to devm_rtc_allocate_device() and rtc_register_device() 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() Kevin Hilman (1): dt-bindings: rtc: new binding for Amlogic VRTC Neil Armstrong (1): rtc: Add Amlogic Virtual Wake RTC .../bindings/rtc/rtc-meson-vrtc.txt | 22 +++ MAINTAINERS | 1 + drivers/rtc/Kconfig | 11 ++ drivers/rtc/Makefile | 1 + drivers/rtc/rtc-meson-vrtc.c | 156 ++++++++++++++++++ 5 files changed, 191 insertions(+) create mode 100644 Documentation/devicetree/bindings/rtc/rtc-meson-vrtc.txt create mode 100644 drivers/rtc/rtc-meson-vrtc.c -- 2.22.0
