[PATCH 0/2] rtc: pcf2127: add default battery-related power-on values

[Hugo Villeneuve <hugo@hugovil.com>]

Hello,
this patch series adds support for setting default battery-related
functions for RTC devices.

This evolved from previous discussions about PCF2127 and also when reviewing
PCF2131 driver:

I decided to add these two new DT properties as generic RTC properties, in the
hope that they can be reused by other RTC drivers if needed.

Patch 1 adds two new DT properties to set battery-related functions. These
properties are generic for all RTC devices.

Patch 2 adds support for these two new DT properties to the PCF2127 driver.
This is especially important for PCF2131 devices which have default PWRMNG
values which disable battery-related functions.

Thank you.
