[PATCH v4 0/4] arm64: rockchip: Pine64 PineTab2 support

[Manuel Traut]

This adds support for the BOE TH101MB31IG002 LCD Panel used in PineTab2 [1] and
PineTab-V [2] as well as the devictrees for the PineTab2 v0.1 and v2.0.

The BOE LCD Panel patch was retrieved from [3]. The function-name prefix has
been adapted and the LCD init section was simplified.

The PineTab2 devicetree patch was retrieved from [4]. Some renaming was needed
to pass the dtb-checks, the brightness-levels are specified as range and steps
instead of a list of values.

[5] and [6] was also used as source for this queue.

Changes in v4:
- Rebased on v6.8-rc1
- BOE TH101MB31IG002 LCD Panel:
  * Picked patches from https://anongit.freedesktop.org/git/drm/drm-misc.git (drm-misc-next)
- PineTab2 dts:
  * Make flash-led a regulator-led and control the regulator by GPIO and set
    V5_MIDU as vin-supply to ensure that LED is working even if all other
    drivers using V5 MIDU are unloaded.
  * Add -regulator suffix to nodes, replace -con suffix by -connector
  * Set lcd pinctrl in .dts instead of .dtsi so it is more clear that this is
    different between pinetab v0.1 and v2.0
  * Remove unused bluetooth uart configuration and pinctrl
  * Increase spi-nor max-speed from 24 to 100 MHz

Changes in v3:
- PineTab2 dts:
    * Remove useless regulator-state-mem nodes for fixed regulators
    * Swap mmc0 and mmc1, so mmc0 is now the internal eMMC

    * Remove enabled/prepared checks since they are done in core.
