According to PSCI standard v0.2, for CPU_SUSPEND call, which is
used by cpu idle framework, bit[16] of state parameter must be 0.
So update bit[16] of property 'arm,psci-suspend-param', which is
used as state parameter, to 0.

Do not return the received positive return code but instead return 0 on

Find the sensor mode by comparing the size of the requested image size
and the sensor mode's image size. The distance between image sizes is the
size in pixels of the non-overlapping regions between the requested size
and the frame-specified size. This logic is borrowed from et8ek8 sensor
driver.

Add g/s_parm framerate support by calling subdev
g/s_frame_interval ops.
This allows user to control sensor framerate by
calling ioctl G/S_PARM.

Thanks Hans,
v2 sent, rebased on your helpers !

The num-interpolated-steps property specifies the number of
interpolated steps between each value of brightness-level table. This is
useful for high resolution PWMs to not have to list out every possible
value in the brightness-level array.

When you want to change the brightness using a PWM signal, one thing you
need to consider is how human perceive the brightness. Human perceive
the brightness change non-linearly, we have better sensitivity at low
luminance than high luminance, so to achieve perceived linear dimming,
the brightness
Dear all,
This series is a third patchset integrating the requested changes.
The first and second patch what tries to solve is the problem of
granularity for high resolution PWMs. The idea is simple interpolate
between 2 brightness values so we can have a high PWM duty cycle (a
16 bits PWM is up
The patch 'backlight: pwm_bl: compute brightness of LED linearly to
human eye' introduced a default brightness-levels table that is used
when brightness-levels is not available in the dts. So move
brightness-levels and default-brightness-level to be optional.

Setting num-interpolated-steps in the dts will allow you to have linear
interpolation between values of brightness-levels. This way a high
resolution pwm duty cycle can be used without having to list out every
possible value in the dts. This system also allows for gamma corrected
values.
