2018-03-28pwm-backlight: Disable backlight on shutdownThierry Reding
When a device is shut down, make sure to disable the backlight. If it stays lit, it gives the impression that the device hasn't turned off. Furthermore keeping the backlight on may consume power, which is not what users expect when they shut down a device. Tested-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com> (cherry picked from commit 5f33b896246a2d9bdf01352de11d4dab96ba2fc9)

2018-03-28pwm_backlight: avoid short blank screen while doing hibernationHuayi Li
Use SIMPLE_DEV_PM_OPS macro will initialize the member "freeze" and "thaw" of pwm_backlight_pm_ops as below, .freeze = suspend_fn, .thaw = resume_fn, then during the process of making hibernation snapshot, screen will be blank at the moment of freezing, and then light at the moment of thawing. this is not the right user experience for suspending to disk. so this patch drops freeze and thaw callback, make the LCD is always lighting before the final shutdown.

2018-03-28pwm-backlight: Fix brightness adjustmentThierry Reding
Split adjustment of the brightness (by changing the PWM duty cycle) from the power on sequence. This fixes an issue where the brightness can no longer be updated once the backlight has been enabled. Reported-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Thierry Reding <treding@nvidia.com> (cherry picked from commit e4bfeda96872bfe6015cd360008b77cd3b981b2b)
2018-03-28pwm-backlight: Allow for non-increasing brightness levelsMike Dunn
Currently the driver assumes that the values specified in the brightness-levels device tree property increase as they are parsed from left to right. But boards that invert the signal between the PWM output and the backlight will need to specify decreasing brightness-levels. This patch removes the assumption that the last element of the array is the maximum value, and instead searches the array for the maximum value and uses that in the duty cycle calculation.

2018-03-28pwm-backlight: Add power supply supportThierry Reding
Backlights require a power supply to work properly. This commit adds a regulator to power up and power down the backlight. Signed-off-by: Thierry Reding <treding@nvidia.com> (cherry picked from commit 22ceeee16eb8f0d04de3ef43a5174fb30ec18af9)
2018-03-28pwm-backlight: Use new enable_gpio fieldThierry Reding
Make use of the new enable_gpio field and allow it to be set from DT as well. Now that all legacy users of platform data have been converted to initialize this field to an invalid value, it is safe to use the field from the driver. Signed-off-by: Thierry Reding <treding@nvidia.com> (cherry picked from commit 8265b2e4e62632b01f998095d1bbda4d281629fe)
2018-03-28pwm-backlight: Track enable stateThierry Reding
Follow up patches will add support for more complex means of powering the backlight on and off such as using a regulator. To prevent calls to the regulator API from becoming unbalanced, keep track of the enabled state internally. Signed-off-by: Thierry Reding <treding@nvidia.com> (cherry picked from commit 97c38437115aa0c3fb2d50c488814b503ba529e0)
2018-03-28pwm-backlight: Refactor backlight power on/offThierry Reding

The m41t0 variant is very similar to the already supported m41t00 variant, with the notable exception of the oscillator fail bit. The data sheet notes: If the oscillator fail (OF) bit is internally set to a '1,' this indicates that the oscillator has either stopped, or was stopped for some period of time and can be used to judge the validity of the clock and date data. The bit will get cleared with a regular write of the system time, so no changes are needed to clear it.
