There are no external users of backlight_put().
Drop it and open code the two users in backlight.c.

The driver required initialization using struct generic_bl_info.
As there are no more references to this struct there is no users left.
So it is safe to delete the driver.

Replaces the open-coded checks if the state etc.,
with the backlight_is_blank() helper.
This increases readability of the code and aling
the functionality.

No need to put "extern" in front of prototypes.
While touching the prototypes adjust indent to follow
the kernel style.

Did this ever go through uAPI review? It's been pushed to the kernel
before Mesa review was complete. Even
Update documentation to list the gpu opp table bindings including the
newly added "opp-peak-kBps" needed for GPU-DDR bandwidth scaling.

Add opp-peak-kBps bindings to the GPU opp table, listing the peak
GPU -> DDR bandwidth requirement for each opp level. This will be
used to scale the DDR bandwidth along with the GPU frequency dynamically.

This is a rework of my previous series [1], but this time based on the bindings
from Georgi [2] + a few fixes which look to be fixed in v8 of Georgi's series
[3]. The work is based on the chromeOS tip.

This patch adds the interconnect bindings to the GPU node. This enables
the GPU->DDR path bandwidth voting.

This patch changes the plumbing to send the devfreq recommended opp rather
than the frequency. Also consolidate and rearrange the code in a6xx to set
the GPU frequency and the icc vote in preparation for the upcoming
changes for GPU->DDR scaling votes.

This patches replaces the previously used static DDR vote and uses
dev_pm_opp_set_bw() to scale GPU->DDR bandwidth along with scaling
GPU frequency.
