[PATCH v5 0/7] FriendlyELEC NanoPC-T6 improvements

[Marcin Juszkiewicz]

This series updates FriendlyELEC NanoPC-T6 situation. There is non-LTS
(2301) version of a board and LTS (2310) version.

This series creates common DTSI for both boards and then separate
NanoPC-T6 and NanoPC-T6 LTS DTS files. This way T6 gets MiniPCIe section
and T6-LTS gets USB20 section.

Then set of changes for both versions are done:

- enable USB-C port (one orientation only)
- enable Mali GPU
- enable IR receiver (tested using ir-keytable)
- enable SPI flash (present on LTS, optional on non-LTS)
- enable Mask Rom button as input device

---
Changes in v5:
- added Reviewed-by to 'add spi flash' patch
- dropped adding SPI M1 pinctl
- changed ir-receiver to have pinctrl like Jonas Karlman suggested
- Link to v4: https://lore.kernel.org/r/20240822-friendlyelec-nanopc-t6-lts-v4-0-892aebcec0c6@linaro.org

Changes in v4:
- added Acked-by to dt-bindings patch
- create common dtsi for both board versions
- nanopc-t6.dts has minipcie items
- nanopc-t6-lts.dts has usb 2.0 host enablement
- Link to v3: https://lore.kernel.org/r/20240821-friendlyelec-nanopc-t6-lts-v3-0-3ecfa996bbe0@linaro.org

Changes in v3:
- create separate NanoPC-T6 LTS devicetree as suggested
- Link to v2: https://lore.kernel.org/r/20240821-friendlyelec-nanopc-t6-lts-v2-0-e0138bb10042@linaro.org

Changes in v2:
- merged changes into NanoPC-T6 dts file
- add SPI flash pinctl for SPI M1
- enable SPI on NanoPC-T6 LTS
- enable USB-C port (one orientation only)
- enable Mali GPI
- enable IR receiver (not tested)
- Link to v1: https://lore.kernel.org/r/20240820-friendlyelec-nanopc-t6-lts-v1-1-da1273c3e08e@juszkiewicz.com.pl

[PATCH v5 2/7] arm64: dts: rockchip: add NanoPC-T6 LTS

[Marcin Juszkiewicz]

FriendlyELEC introduced a second version of NanoPC-T6 SBC.

Create common include file and separate DT files for each version of the
board.

In the LTS version the miniPCIe slot got removed and USB 2.0 setup has
changed. There are two external accessible ports and two ports on the
internal header.

There is an on-board USB hub which provides:
- one external connector (bottom one)
- two internal ports on pin header
- one port for m.2 E connector

The top USB 2.0 connector comes directly from the SoC.

Would it be useful to split this patch up as follows?
- Move common parts to dtsi and update the non-lts version to use that
- Improve the dtsi file (optionally)
- Improve the non-lts dts file (optionally)
- Add the lts version

I like comments like these, but I wonder if such things don't make the
diff (way) larger then needed.

Cheers,

So as Diederik already mentioned, this definitly needs to be split up.
Simply because it's hard to read and make verify that nothing slipped in.

So please the move from dts to dtsi should be its own separate patch
and a second patch then can add the "lts" devicetree on top.
