regualtor: pfuze100: correct sw1a/sw2 on pfuze3000

2020-07-01T03:17:10+00:00

[ Upstream commit 6f1cf5257acc6e6242ddf2f52bc7912aed77b79f ]

PFUZE100_SWB_REG is not proper for sw1a/sw2, because enable_mask/enable_reg
is not correct. On PFUZE3000, sw1a/sw2 should be the same as sw1a/sw2 on
pfuze100 except that voltages are not linear, so add new PFUZE3000_SW_REG
and pfuze3000_sw_regulator_ops which like the non-linear PFUZE100_SW_REG
and pfuze100_sw_regulator_ops.

regulator: rk808: Lower log level on optional GPIOs being not available

2020-02-24T07:34:40+00:00

[ Upstream commit b8a039d37792067c1a380dc710361905724b9b2f ]

RK808 can leverage a couple of GPIOs to tweak the ramp rate during DVS
(Dynamic Voltage Scaling). These GPIOs are entirely optional but a
dev_warn() appeared when cleaning this driver to use a more up-to-date
gpiod API. At least reduce the log level to 'info' as it is totally
fine to not populate these GPIO on a hardware design.

This change is trivial but it is worth not polluting the logs during
bringup phase by having real warnings and errors sorted out
correctly.

While at it also make the array const and change to use unsigned int.

regulator: fix use after free issue

2020-01-12T11:17:05+00:00

[ Upstream commit 4affd79a125ac91e6a53be843ea3960a8fc00cbb ]

This is caused by dereferencing 'rdev' after put_device() in
the _regulator_get()/_regulator_put() functions.
This patch just moves the put_device() down a bit to avoid the
issue.
