Latest pfuze3000 datasheet from:
http://cache.freescale.com/files/analog/doc/data_sheet/PF3000.pdf?fsrch=1&sr=1&pageNum=1
updates sw1a's voltage range, the settings for 1.450V and 1.475V
are replaced with 1.8V and 3.3V:
5b'11110 1.450 (SW1B), 1.8 (SW1A/SW1AB)
5b'11111 1.475 (SW1B), 3.3 (SW1A/SW1AB)
the voltage calculation using steps is NOT available for sw1a now,
use voltage table instead.

Latest pfuze3000 datasheet from:
http://cache.freescale.com/files/analog/doc/data_sheet/PF3000.pdf?fsrch=1&sr=1&pageNum=1
updates sw1a's voltage range, the settings for 1.450V and 1.475V
are replaced with 1.8V and 3.3V:
5b'11110 1.450 (SW1B), 1.8 (SW1A/SW1AB)
5b'11111 1.475 (SW1B), 3.3 (SW1A/SW1AB)
the voltage calculation using steps is NOT available for sw1a now,
use voltage table instead.

this link goes to Rev. 7.0, 9/2016, which isn't the latest one.
I guess Rev. 9.0, 8/2017 is the latest.

This change does not look like a safe thing to do without carefully
checking each one of the board schematics.
Even if the regulator itself is capable of driving a higher voltage,
it does not mean that the circuitry that consumes such regulator is
allowed to receive the higher voltages.

Even if the regulator itself is capable of driving a higher voltage,
it does not mean that the circuitry that consumes such regulator is
allowed to receive the higher voltages.

I thought the max value here means the capability of regulator itself, like the internal
anatop LDO regulator VDD_CORE, the max value defined in dtsi is 1.45V, but out i.MX6
SoCs can NOT receive to voltage higher than 1.3V.
The default setting of PMIC output is controlled by its OTP and the OTP value should
consider the board design, the rest of voltage setting should be taken care by device driver.
Here I think the max means PMIC's capability.

OK, so I should change the max value of SW1A according to board design, such
as for MX7D, it is 1.075V for max cpu-freq's voltage, set it to 1.075 in dts?
Also, according to the binding doc, do you think the anatop's vdd_arm and vdd_soc/pu's max
value also need to be adjusted to match the value define in each soc's datasheet?

OK, so I should change the max value of SW1A according to board design, such
as for MX7D, it is 1.075V for max cpu-freq's voltage, set it to 1.075 in dts?
Also, according to the binding doc, do you think the anatop's vdd_arm and vdd_soc/pu's max
value also need to be adjusted to match the value define in each soc's datasheet?

The patch
regulator: pfuze100: update voltage setting for pfuze3000 sw1a
has been applied to the regulator tree at
https://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,

sw1a
pfuze3000 datasheet(Rev.9.0) from:

updates sw1a's voltage range, the settings for 1.450V and 1.475V
are replaced with 1.8V and 3.3V:
5b'11110 1.450 (SW1B), 1.8 (SW1A/SW1AB)

the voltage calculation using steps is NOT available for sw1a now,
use voltage table instead.
