[PATCH v2 0/2] Add a driver for Epson RX8111 RTC

[Waqar Hameed]

In this patch series we add a basic driver for Epson RX8111 RTC with support for
only reading/writing the time and the `ioctl`s `RTC_VL_READ` and `RTC_VL_CLR`.

Datasheet: https://support.epson.biz/td/api/doc_check.php?dl=app_RX8111CE&lang=en

Changes in v2:
* Move dt-bindings to `trivial-rtc.yaml`.

Link to v1: https://lore.kernel.org/lkml/cover.1691158774.git.waqar.hameed@axis.com/

I decided to send v2 now since it has been a while, and I didn't get any
comments for `rtc-rx8111.c` in v1.

[PATCH v2 1/2] dt-bindings: rtc: Add Epson RX8111

[Waqar Hameed]

Epson RX8111 is an RTC with timestamp functionality. Add devicetree
bindings requiring the compatible string and I2C slave address (reg)
through `trivial-rtc.yaml`.
