[PATCH v4 0/5] k3-am68-phyboard-izar dsi support

[Dominik Haller]

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
