The patch

   regulator: lm363x: Fix off-by-one n_voltages for lm3632 ldo_vpos/ldo_vneg

has been applied to the regulator tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.4

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

Subject: [PATCH] regulator: lm363x: Fix off-by-one n_voltages for lm3632
 ldo_vpos/ldo_vneg

According to the datasheet https://www.ti.com/lit/ds/symlink/lm3632a.pdf
Table 20. VPOS Bias Register Field Descriptions VPOS[5:0]
Sets the Positive Display Bias (LDO) Voltage (50 mV per step)
000000: 4 V
000001: 4.05 V
000010: 4.1 V
....................
011101: 5.45 V
011110: 5.5 V (Default)
011111: 5.55 V
....................
100111: 5.95 V
101000: 6 V
Note: Codes 101001 to 111111 map to 6 V

The LM3632_LDO_VSEL_MAX should be 0b101000 (0x28), so the maximum voltage
can match the datasheet.
