2019-11-27rtc: meson: remove redundant assignment to variable retriesColin Ian King1-1/+1
The variable retries is being initialized with a value that is never read and it is being updated later with a new value in a for-loop. The initialization is redundant and can be removed.

2019-02-17rtc: meson: remove useless rtc_nvmem_unregister callAlexandre Belloni1-4/+1
rtc_nvmem_unregister() is called on rtc_device release so it is not necessary to call it from the driver. Reviewed-by: Martin Blumenstingl <[email protected]> Signed-off-by: Alexandre Belloni <[email protected]>
2019-02-11rtc: support for the Amlogic Meson RTCMartin Blumenstingl1-0/+410
Add support for the RTC block on the 32-bit Amlogic Meson6, Meson8, Meson8b and Meson8m2 SoCs. The RTC is split in to two parts, which are both managed by this driver: - the AHB front end - and a simple serial connection to the actual registers The RTC_COUNTER register which holds the time is 32-bits wide. There are four 32-bit wide (in total: 16 bytes) "regmem" registers which are exposed using nvmem. On Amlogic's 3.10 kernel this is used to store data which needs to survive a suspend / resume cycle.
