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.
