[PATCH V2 0/6] mfd: tp6586x: enhancements in the driver

[Laxman Dewangan <ldewangan@nvidia.com>]

Doing some enhancements in the tps6586x core driver which is
based on some recent driver framework enhancements.
Following are highlights of changes:
- Use devm for allocation to remove the code for freeing it.
- Use regmap i2c for register access in place of direct i2c apis.
  This will give the debug fs and cache functionality through regmap
  framework.
- Use the regmap caching for some fo register in place of local
  implementation.
- Move the gpio support driver to the drivers/gpio and implement it as
  platform driver. The registration will be done as mfd sub devices.


Changes V1 -> V2:
- Remove the unnecessariy header inclusion in the gpio-tps6586x.
- To avoid bisect functionality break, grep the user of tps6586x and
  found that tegra_defconfig is only using this. Added the
  GPIO_TPS6586x in config variable on this series.
  This results 6 patch on this series.
