Pull MFD updates from Lee Jones:
"New Drivers:
- Add support for TI TPS6594/TPS6593/LP8764 PMICs
- Add support for Samsung RT5033 Battery Charger
- Add support for Analog Devices MAX77540 and MAX77541 PMICs
New Device Support:
- Add support for SPI to Rockchip RK808 (and friends)
- Add support for AXP192 PMIC to X-Powers AXP20X
- Add support for AXP313a PMIC to X-Powers AXP20X
- Add support for RK806 to Rockchip RK8XX
Removed Device Support:
- Removed MFD support for Richtek RT5033 Battery
Fix-ups:
- Remove superfluous code
- Switch I2C drivers from .probe_new() to .probe()
- Convert over to managed resources (devm_*(), etc)
- Use dev_err_probe() for returning errors from .probe()
- Add lots of Device Tree bindings / support
- Improve cache efficiency by switching to Maple
- Use own exported namespaces (NS)
- Include missing and remove superfluous headers
- Start using / convert to the new shutdown sys-off API
- Trivial: variable / define renaming
- Make use of of_property_read_reg() when requesting DT 'reg's
Bug Fixes:
- Fix chip revision readout due to incorrect data masking
- Amend incorrect register and mask values used for charger state
- Hide unused functionality at compile time
- Fix resource leaks following error handling routines
- Return correct error values and fix error handling in general
- Repair incorrect device names - used for device matching
- Remedy broken module auto-loading"
