There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the omapfb sysfs code to use default_groups field which has
been the preferred way since aa30f47cf666 ("kobject: Add support for
default attribute groups to kobj_type") so that we can soon get rid of
the obsolete default_attrs field.

The GEM controllers on ZynqMP were missing some initialization steps which
are required in some cases when using SGMII mode, which uses the PS-GTR
transceivers managed by the phy-zynqmp driver.
The GEM core appears to need a hardware-level reset in order to work
properly in SGMII mode in cases where the GT reference clock was not
present at initial power-on. This can be done using a reset mapped to
the zynqmp-reset driver in the device tree.
Also, when in SGMII mode, the GEM driver needs to ensure the PHY is
initialized and powered on.

The driver was implementing a get_brightness function that
tried to read back the PWM setting of the display to report
as the current brightness.
The controller on the display does not support that, therefore
we end up reporting a brightness of 0, and that confuses
systemd's backlight service.
Remove the hook so that the framework returns the current
brightness automatically.

The driver was using the regmap lock to serialise the

The driver overrides the error codes returned by platform_get_irq() to

The module identifying will try to get the sub device data which
will be ready after sub device initialisation, so if try to use the
subdev data to deference the client will cause NULL pointer
dereference, this patch move the module identification after
v4l2_i2c_subdev_init() to fix this issue, it also fixes duplicate
module idendification.
