2012-05-04tps6586x: Add device tree supportThierry Reding4-0/+185

2012-05-04regulator: Add generic DT parsing for regulatorsThierry Reding2-0/+65
Looking up init data for regulators found on chips is a common operation that can be handled in a generic way. The new helper function introduced by this patch looks up the children of a given node by names specified in a match table and fills that match table with information parsed from the DT. This is based on work by Rhyland Klein <rklein@nvidia.com>. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-04-23regulator: Remove unneeded include of linux/delay.h from regulator driversAxel Lin16-16/+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>

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.

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.

2012-04-16mfd: add irq domain support for max8997 interruptsThomas Abraham6-33/+39
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.

2012-04-10regulator: twl-regulator: Fix off-by-one vsel setting in twl6030smps_set_voltageAxel Lin1-4/+10
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.

This patch makes the code easier to read. Also add checking the case when no desc id is matched.

2012-04-10regulator: max8997: Remove n_bits from struct voltage_map_descAxel Lin1-9/+5
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.

2012-04-10regulator: Rework s5m8767_set_voltage to support both LDOs and BUCKsAxel Lin1-94/+49
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.
