* regulator: max8997: Convert ot use devm_kzallocAxel Lin2012-04-231-25/+15
| | | | | | | | | | | Also simplify the error handling to start unwind from the place regulator_register fails. No need to check rdev[i] is NULL or not before calling regulator_unregister. regulator_unregister is safe if rdev is NULL, Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* regulator: Remove unneeded include of linux/delay.h from regulator driversAxel Lin2012-04-2316-16/+0
| | | | | | | | | | | | | All the drivers that need delay for the regulator voltage output voltage to stabilize after being enabled or after being set to a new value has been converted to implement enable_time and set_voltage_time_sel callbacks. Then regulator core will take care of the necessary delay. For the drivers that don't need the delay, don't need to include linux/delay.h. This patch removes the unneeded include of linux/delay.h in regulator drivers. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* regulator: max8997: Remove empty set_suspend_enable callback implementationAxel Lin2012-04-231-9/+0
| | | | | | | | | Since commit 8ac0e95 "regulator: core: Support setting suspend_[mode|voltage] if set_suspend_[en|dis]able is NULL", now the regulator core can properly handle the case set_suspend_enable callback is NULL.

| | | | | | | | | | | | | max8997_charger_fixedstate_ops If is_enabled callback is not implemented, the core assumes that the regulator is on. This is simpler than having a hack to retrun 1 in max8997_reg_is_enabled() if max8997_get_enable_register() returns -EINVAL.

* regulator: s5m8767: Use DIV_ROUND_UP to calculate selectorAxel Lin2012-04-231-1/+4
| | | | | | | | | | | Integer division may truncate the result. Use DIV_ROUND_UP to ensure new voltage setting falls within specified range. Also properly handle the case min_vol < desc->min to ensure we don't return negative value for selector.

| | | | | | | | | | | | | | Add irq domain support for max8997 interrupts. The reverse mapping method used is linear mapping since the sub-drivers of max8997 such as regulator and charger drivers can use the max8997 irq_domain to get the linux irq number for max8997 interrupts. All uses of irq_base in platform data and max8997 driver private data are removed.

| | | | | | | | | | | | | | commit 268a1 "regulator: twl-regulator: Use DIV_ROUND_UP at appropriate places" introduced an off-by-one bug for setting vsel. The linear calculation code in twl6030smps_list_voltage() does subtract index by 1 so we need the vsel++ after DIV_ROUND_UP. The original code use this trick to differentiate if we are going to set the voltage to 0 or the voltage falls within the linear calculation range.

| | | | | | | | | | | | | | | The n_bits is only used in max8997_get_voltage_proper_val to check the valid range for variable i. Current code already ensures min_vol never greater than desc->max, which means the variable i always in the valid range: 0 .. (desc->max - desc->min)/desc->step. Thus we can remove the checking (i >= (1 << desc->n_bits) and then remove n_bits from struct voltage_map_desc.

| | | | | | | | | | | | | | | | | | | | s5m8767_set_voltage not only implement set_voltage callbacks for LDOs, but also for BUCKs when s5m8767->buck_gpioindex is not set. s5m8767_set_voltage_buck actually only for buck[2|3|4] when s5m8767->buck_gpioindex is set. Conditionally calling s5m8767_set_voltage in s5m8767_set_voltage_buck makes the code hard to read. I think merging s5m8767_set_voltage_buck and s5m8767_set_voltage actually simplifies things. It's easy to use buck234_vol pointer to differentiate if we need to control voltage for buck[2|3|4] by DVS GPIOs. This patch reworks s5m8767_set_voltage to support both LDOx and BUCKx in all cases.
