Some drivers call video_set_flush_dcache() to indicate that they want to
have the dcache flushed for the frame buffer. These drivers benefit from
our new video damage control, because we can reduce the amount of memory
that gets flushed significantly.
This patch enables video damage control for all device drivers that call
video_set_flush_dcache() to make sure they benefit from it.

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

Use device-tree node property names for parsing nodes instead of
indexing as indexing could be different between different SoCs based on
number of DSS entities available on that particular SoC.
Also correct the video layer naming in driver to match to actual one
being used in upstream DSS device-tree node [1].
This also fixes AM62x splash screen usage using the latest upstream DSS
device-tree nodes where hard-coded indexing which driver was using
before this patch was not matching the correct properties in the DT
node.

Perform removal of DSS if kconfigs VIDEO_REMOVE or SPL_VIDEO_REMOVE is
set by user. Otherwise if above Kconfigs are not selected, it is assumed
that user wants splash screen to be displayed until linux kernel boots
up. In such scenario, leave the power domain of DSS as "on" so that
splash screen stays intact until kernel boots up.

Change remove method of DSS video driver to disable video port instead
of performing a soft reset, as soft reset takes longer duration. Video
port is disabled by setting enable bit of video port to 0.

To enable TIDSS driver only at SPL stage add rule to compile the TIDSS
video driver.
CONFIG_$(SPL_)VIDEO_TIDSS will compile tidss_drv, at SPL only if
CONFIG_SPL_VIDEO_TIDSS is defined and at u-boot proper if
CONFIG_VIDEO_TIDSS is defined.

Added tidss video driver support which enables display
on oldi panel using AM62x, it creates a simple pipeline
framebuffer==>vidl1==>ovr1==>vp1==>oldi_panel and
calculates clock rates for panel from panel node in
device tree.
To compile TIDSS when user sets CONFIG_VIDEO_TIDSS
add rule in Makefile. Include tidss folder location
in Kconfig.
TIDSS is ported from linux kernel version 5.10.145
