[PATCH] regulator: rk808: Add apply_bit for BUCK3 on RK809

[Mikhail Rudenko]

Currently, RK809's BUCK3 regulator is modelled in the driver as a
configurable regulator with 0.5-2.4V voltage range. But the voltage
setting is not actually applied, because when bit 6 of
PMIC_POWER_CONFIG register is set to 0 (default), BUCK3 output voltage
is determined by the external feedback resistor. Fix this, by setting
bit 6 when voltage selection is set. Existing users which do not
specify voltage constraints in their device trees will not be affected
by this change, since no voltage setting is applied in those cases,
and bit 6 is not enabled.

Please don't send content free pings and please allow a reasonable time
for review.  People get busy, go on holiday, attend conferences and so 
on so unless there is some reason for urgency (like critical bug fixes)
please allow at least a couple of weeks for review.  If there have been
review comments then people may be waiting for those to be addressed.

Sending content free pings adds to the mail volume (if they are seen at
all) which is often the problem and since they can't be reviewed
directly if something has gone wrong you'll have to resend the patches
anyway, so sending again is generally a better approach though there are
some other maintainers who like them - if in doubt look at how patches
for the subsystem are normally handled.

Please don't top post, reply in line with needed context.  This allows
readers to readily follow the flow of conversation and understand what
you are talking about and also helps ensure that everything in the
discussion is being addressed.

[1/1] regulator: rk808: Add apply_bit for BUCK3 on RK809
      commit: 5e53e4a66bc7430dd2d11c18a86410e3a38d2940

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
