Firstly, the upstream patch for sun4i-drm ensures the HDMI output is initialized successfully.
Secondly, patching drm_atomic_helper_connector_hdmi_check() avoids a null pointer dereference at shutdown or reboot
Although my initial testing appeared to be a success, subsequent
testing finds it to fail more often than it works.
Back to square one.

The old method carried along with board-pbp-add-dp-alt-mode.patch only
makes typec work in one(normal) orientation. This patch introduces a
proper extcon driver and makes the workaround cleaner, so orientation
switch is working.
Improvements:
- type-c DP on rk3399 works with both orientations
- type-c USB 3.0 on rk3399 works with both orientations, with minor
issues, see below
Caveats:
- Powered USB-C hubs may be not recognized, and can be worked around by
loading a gadget driver, or manually toggling the mode once for each
connection.
- Some dual-role devices(phone, tablet) may be not recognized.
Affected boards:
- TinkerBoard 2/2S
- Pinebook Pro
- NanoPC T4
- Orange Pi 4
- Orange Pi 4 LTS
Tested on tinkerboard 2s. This patch contains other minor fixes for
tinker2's device tree, including adding a missing fan node, adding color
labels to leds.
The 2 patches adding dp support for nanopc t4 and pinebook pro are also
updated accordingly.
The device trees of Orange Pi 4 / 4 LTS are also updated to match the
new implementation.
* remove the patches that are shredding upstream device tree
* consolidation into single patch that apply over upstream dt
* add pcm5102a device tree overlay for handy usage
* correct system patch used for aliasing on Allwinner A10, A13 and A20 to ensure consistent allocation of device IDs
* Re-introduce spi overlays for each bus so that when used in conjuction with a device driver overlay, the pins are correctly muxed into SPI mode
* Ensure SPI overlay patches are applied
* Fix typo in patch name
* Move alias patches further down series.conf to ensure they are only called after the intial overlay creation
* Rephrase subject heading to improve clarity
* Fix interface aliases on Allwinner A10 for I2C, SPI and UART
* Fix interface aliases on Allwinner A13 for I2C and UART
* Fix interface aliases on Allwinner A20 for I2C, SPI and UART
* Fix SPI 2 pin names in line with latest revision of the Allwinner A10 device tree
* Fix SPI 2 pin names in line with latest revision of the Allwinner A20 device tree
* Create overlays for each bus on the Allwinner A20 so that the corresponding pins can be set into spi mode
* Create overlays for each bus on the Allwinner A10 so that the corresponding pins can be set into spi mode
* Condense alias path corrections into the intial overlay creation patch instead of applying a further patch on topof it to enact these corrections
* Remove references to our no longer needed addtional overlays
* rename to include 'arm-dts..' for consistency with other dts related patches
* Fix mistake in SPI overlay patches naming which leads to build failure
* Fix typo in application of spi2 overlay that was leading to compilation failure
* Amend the assigned aliases in overlay creation so that the kernel correctly maps the bus/port number to match the physical hardware numbering
* Update pin labels for SPI 2 to use current names as defined in sun4i-a10.dtsi and sun7i-a20.dtsi. fixed typo in sun5i-a13-spi-spidev as compatibility field should be sun5i-a13
* Re-introduce compilation of spi bus overlays on Allwinner A10 and A20 SOCs which are necessary to ensure that the pins are correctly muxed into spi mode
