[PATCH V3 0/6] mfd: tp6586x: enhancements in the driver

From: Laxman Dewangan
Date: Wed Jul 18 2012 - 02:29:45 EST


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.

Changes V2->V3
- Revert the irq regsitration through devm_* and used normal api.
- Rebased the series with above change as there was conflict.

Laxman Dewangan (6):
mfd: tps6586x:use devm managed resources
mfd: Use regmap for tps6586x register access.

gpio: tps6586x: add gpio support through platform driver
ARM: tegra: defconfig: enable tps6586x gpio
mfd: tps6586x: remove gpio support from core driver
