commit 4ca1e1d9 "regulator: Convert 88pm8607 to set_voltage_sel" accidentally changed the value writing to vol_reg. What we want is to write val instead of selector to vol_reg. Signed-off-by:

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. Signed-off-by:

There's no need to implement set_voltage() as there is only a very small range of selectors for the regulators in the WM8994 and the voltages are not expected to vary frequently at runtime. Signed-off-by:

We don't support missing configs at all so segfaulting isn't that bad but since we've got checks in the code move the dereference after them. Signed-off-by: -

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. Signed-off-by:

This patch makes the code easier to read. Also add checking the case when no desc id is matched. This is required because if no desc id is matched, the poiner info is pointed to twl_of_match[i].data which may be not NULL. Checking info is NULL or not latter does not catch the error. Signed-off-by:

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. Signed-off-by:

All the callback function implementation are the same for both LDOs and BUCKs. Merge them to one s5m8767_ops. Signed-off-by:

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.
