PATCH v6 2/2 regulator: rt6160: Add support for Richtek RT6160

From: ChiYuan Huang <[email protected]>

Add support for Richtek RT6160 voltage regulator. It can provide up to 3A output current within the adjustable voltage from 2025mV to 5200mV. It integrate a buckboost converter to support wide input voltage range from 2200mV to 5500mV.

since v6
- Emergency fix for kernel test robot PTR_ERR fail.

since v5
- Add 'enable" gpio control into regulator enable/disable.
- Refine regulator ramp delay ops.
- Due to 'enable' gpio H to L cause register reset, use regcache.

since v4
- Add of_node into regulator_config to fix regulator_get by device tree node parsing.

since v3
- Use more header file like as of_regulator.h and property.h.
- Change the parsing string from 'richtek,vsel_active_low' to 'richtek,vsel-active-low'.
- Use of_get_regulator_init_data to get the regulator init_data.

since v2
- Fix W=1 warning for of_device_id.

Thanks!

[1/2] regulator: rt6160: Add DT binding document for Richtek RT6160

      commit: bce18e52c866ff6ded13ac8ac37e9271f786c005
[2/2] regulator: rt6160: Add support for Richtek RT6160
      commit: de20b747c5836ffc6768914b95d7617139fac4f4

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks,
Mark
