You are just writing the enable_mask (BTW, just use the enable_mask,
not the value itself in such case) instead of enabling the suspend
mode. In the disable callback you are just disabling the regulator.

What do you want to achieve with these callbacks?

Best regards,
Krzysztof

I missed that the register is different - sleep_reg instead of
enable_reg. It makes sense and as this is separate register then usage
of desc->enable_mask is up to you, I think.

        return regmap_update_bits(di->regmap, di->sleep_reg,
                                  VSEL_BUCK_EN, VSEL_BUCK_EN);
This callback is setting sleep_reg, setting this dcdc output is enable 
or disable when system enter sleep.
In our system this dcdc need disabled when sleep. But the current 
software not support.

The patch

   regulator: fan53555: fill set_suspend_enable/disable callback

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
