This patch set is to add Richtek RT9759 smart cap divider charger.

The RT9759 is a high efficiency and high charge current charger.
The efficiency is up to 97.8% when VBAT=4.2V, IBAT=2.5A, and the maximum
charge current is up to 8A. The device integrates smart cap divider topology
with a dual-phase charge pump core and 9 channel high speed ADCs to monitor
the charging process.

Since v3:
- Fix 0002 patch title typo (from 'rt9471' to 'rt9759')
- Remove unused R_VAC_OVP range.
- Refer to ABI document, use 'status' to control battery charging, not 'online'
- Refer to ABI document, use 'online' to indicate bus state

Since v2:
- Add Reviewed-by tag for dt-binding patch
- Change ABI document date from Oct 2022 to Nov 2022 and KernelVersion
  from 6.1 to 6.2
