Pull MFD updates from Lee Jones:
"New Device Support
- Add support for Ricoh RC5T619 PMIC to rn5t618
- Add support for PM8821 PMIC to qcom-pm8xxx
New Functionality:
- Add support for GPIO to lpc_ich
- Add support for GPADC to sun4i
- Add ability for rk808 to shutdown
Fix-ups:
- Simplify/strip unnecessary code; tps65218, palmas, tps65217
- Device Tree binding updates; tps65218, altera-a10sr
- Provide/export device ID info; tps65218, axp20x-i2c, hi655x-pmic,
fsl-imx25-tsadc, intel_soc_pmic_bxtwc
- Use MFD API instead of of_platform_populate(); tps65218
- Generalise name-space; pm8xxx
- Supply/edit regmap configuration; axp20x, cs47l24-tables, axp20x
- Enable compile testing; max77620, max77686, exynos-lpass,
abx500-core
- Coding style issues; wm8994-core, wm5102-tables
- Supply endian support; syscon
- Remove module support; ab3100-core, ab8500-debugfs, ab8500-gpadc,
abx500-core
Bug Fixes:
- Fix ordering issues; wm8994
- Fix dependencies (build-time/run-time); exynos_lpass, sun4i-gpadc
- Fix compiler warnings; sun4i-gpadc
- Fix leaks; mfd-core
- Fix page fault during module unload; tps65217"
