 "Not much this cycle apart from the ingenic rtc driver rework.

  The fixes are mainly minor issues reported by coccinelle rather than
  real world issues.

  Subsystem:

   - new VL flag for backup switch over

  Drivers:

   - ingenic: only support device tree

   - pcf2127: report battery switch over, handle nowayout"

sh: remove sh5 support

2020-06-01T18:48:52+00:00

sh5 never became a product and has probably never really worked.

Remove it by recursively deleting all associated Kconfig options
and all corresponding files.

rtc: ingenic: Only support probing from devicetree

2020-05-11T14:34:54+00:00

With the recent work on supporting Device Tree on Ingenic SoCs, no
driver ever probes from platform code anymore, so we can clean a bit
this driver by removing the non-devicetree paths.

rtc: class: support hctosys from modular RTC drivers

2020-03-23T20:14:34+00:00

Due to distribution constraints it may not be possible to statically
compile the required RTC driver into the kernel.

Expand RTC_HCTOSYS support to cover all RTC devices (statically compiled
or not) by checking at the end of RTC device registration whether the
time should be synced.
