| * | | | regulator: ab8500-ext: Get rid of is_enabled from struct ↵Axel Lin2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ab8500_ext_regulator_info The intention of this patch is to simplify the code. Maintain the is_enabled flag is not trivial, it not only needs to set/clear the flag in disable()/enable() but also needs to set the flag in is_enable() to get initial status. The only benefit of keeping is_enabled flag is just save a register read when set_mode(). Remove is_enabled flag makes the code simpler.

The only benefit of keeping is_enabled flag is just save a register read when set_mode(). Remove is_enabled flag makes the code simpler. This patch also moves ab8500_regulator_is_enabled() close to ab8500_regulator_[en|dis]able functions. This is required to avoid a forward declaration because now we call ab8500_regulator_is_enabled() in ab8500_regulator_set_mode(). This change also makes the code better in readability by moving similar functions to one place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ab*_match[] arrays should be moved out of the way, instead of bunched in the middle of the initialisation functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch ensures that many of the recent developments pertaining to the AB8500 regulator device are propagated out into the public arena. It aims to update some of the existing initialisation values in accordance with internal ST-Ericsson code submissions. This single patch was originally a collection of updates which have been squashed together to aid with clarity.

The register value is defined in the board configuration. This patch puts a mask in the board configuration to specify which bits should actually be altered. The purpose with this patch is to avoid future mistakes when updating the allowed bits in the regulator driver.

The regulator register order depends on the regulator ID pass to ab3100_regulator_register() function. Thus we need to scan ab3100_regulator_desc and find the index of successfully registered regulators, or alternatively just call ab3100_regulators_remove() to unregister all registered regulators. Since current code uses a static ab3100_regulators table, explicitly set reg->rdev = NULL after regulator_unregister() call to ensure calling ab3100_regulators_remove() in the unwind path always work. Also move ab3100_regulators_remove() to avoid forward declaration. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

The initial settings are moved out of platform data and into the driver for the device tree case, as it appears that there is no way to supply this as AUXDATA for an I2C device. The style and bindings are heavily inspired by Lee Jones' style for AB8500.
