[ Upstream commit 6a0fcc87c9e35191d37a8819fdab9d30e523515b ]
Allow disabling and re-enabling battery charging of an axp209 PMIC
through a writable status property. With the current driver code
charging is always on.
This works on the axp209 of Banana {Pi M1+,Pro} and should work on all
AXP chips.

commit 81af7f2342d162e24ac820c10e68684d9f927663 upstream.
Round constant_charge_voltage writes down to the first supported lower
value, rather then rounding them up to the first supported higher value.
This fixes e.g. writing 4250000 resulting in a value of 4350000 which
might be dangerous, instead writing 4250000 will now result in a safe
4200000 value.

commit b34ce4a59cfe9cd0d6f870e6408e8ec88a964585 upstream.
info->max_cv is in millivolts, divide the microvolt value being written
to constant_charge_voltage by 1000 *before* clamping it to info->max_cv.
Before this fix the code always tried to set constant_charge_voltage
to max_cv / 1000 = 4 millivolt, which ends up in setting it to 4.1V
which is the lowest supported value.

The rt9455_boost_voltage_values[] array is only used when USB PHY
support is enabled, causing a W=1 warning otherwise:
drivers/power/supply/rt9455_charger.c:200:18: error: 'rt9455_boost_voltage_values' defined but not used [-Werror=unused-const-variable=]
Enclose the definition in the same #ifdef as the references to it.

[ Upstream commit 2df70149e73e79783bcbc7db4fa51ecef0e2022c ]
The bq27xxx i2c-client may not have an IRQ, in which case
client->irq will be 0. bq27xxx_battery_i2c_probe() already has
an if (client->irq) check wrapping the request_threaded_irq().
But bq27xxx_battery_i2c_remove() unconditionally calls
free_irq(client->irq) leading to:
[ 190.310742] ------------[ cut here ]------------
[ 190.310843] Trying to free already-free IRQ 0
[ 190.310861] WARNING: CPU: 2 PID: 1304 at kernel/irq/manage.c:1893 free_irq+0x1b8/0x310
Followed by a backtrace when unbinding the driver. Add
an if (client->irq) to bq27xxx_battery_i2c_remove() mirroring
probe() to fix this.
