The RK818 chip is a power management IC for multimedia and handheld
devices. It contains the following components:
- Regulators
- RTC
- Clkout
- battery support
Both chips RK808 and RK818 are using a similar register map.
So we can reuse the RTC and Clkout functionality.

The driver was using only linear ranges. Now we remove linear range
definitions with a single range. So we have to add an ops struct for
ranges and adjust all other ops functions accordingly.

The patch
regulator: rk808: remove linear range definitions with a single range
has been applied to the regulator tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git
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

with this patch applied, 4.6.0-rc5-next-20160426 fails to boot on
rk3288-veyron devices with the bug below. Reverting this one patch
results in the system booting again:

This is because I missed to add the correct ops for LDO_REG3 in this patch.

This and some other cleanups are now available as a signed tag from my

regulator: rk808: Some cleanups for the rk808 driver
These are tagged to facilitate the addition of support for the rk818

A common simplified DT parsing code for regulators was introduced in
commit a0c7b164ad11 ("regulator: of: Provide simplified DT parsing
method")
While at it also added RK8XX_DESC and RK8XX_DESC_SWITCH macros for the
regulator_desc struct initialization. This just makes the driver more compact.

The RK808 and RK818 PMICs are using a similar register map.
We can reuse the rtc driver for the RK818 PMIC. So let's add
the RK818 in the Kconfig description.

This driver can also be built as a module. If so, the module
