H A D | rtc-meson.c | d8fe6009 Fri Feb 08 18:18:13 CST 2019 Martin Blumenstingl <martin.blumenstingl@googlemail.com> rtc: support for the Amlogic Meson RTC
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.
