This series adds support for the two dsi based display interfaces of the
phyboard-izar with the phycore-am68x/tda4x som.

dsi0 gets converted to lvds on the som using a SN65DSI83 bridge in the
default configuration. The phyboard-izar kit comes with a 10.1" lvds
display with usb touch as addon.

dsi1 is routed to the carrier board onto a connector. To use that Phytec
has developed a small extension board "PEB-AV-15" with a Lontium LT8912B
dsi->hdmi bridge.

Changes for v2:
- Drop the following patch as it got merged in the last window:
  dt-bindings: display: bridge: lt8912b: Drop reset gpio requirement

- In arm64: dts: ti: k3-am68-phyboard-izar: Add LVDS-Display
  Reduce pwm frequency to ~23kHz for the backlight. This is supported by
  the backlight and works better with most fans. Since the fan connector
  is using PWM0_A and the backlight PWM0_B they need to use the same
  frequency.

- In arm64: dts: ti: k3-am68-phyboard-izar: Add PEB-AV-15 overlay
  Fix license in boilerplate: s/GPL-2.0-or-only or MIT/GPL-2.0-only OR MIT

Changes for v3:
- In arm64: dts: ti: k3-j721s2-main: Add DSI1
  Pick up Beleswar's Reviewed-by from v1

- In arm64: dts: ti: k3-am68-phyboard-izar: Add PEB-AV-15 overlay
  Fix the remaining style issues pointed out by Vignesh in v2

I have applied the following to branch ti-k3-dts-next on [1].

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
