* ARM: dts: imx6qdl-dhcom: Move IPU iomux node from PDK2 to SoM fileChristoph Niedermaier2022-08-221-0/+33
| | | | | | | | | | | | | The SoM itself provides the display interface, see [1] page 20. Those pins have to be used as the RGB/DPI interface or not used at all. So rather than duplicate the pinmux settings in every carrier board DT, better move them into the SoM DTSI.

* ARM: dts: imx6qdl-dhcom: Add USB overcurrent pin on SoM layerChristoph Niedermaier2021-12-161-0/+1
| | | | | | | | | | | | | | | | | | Add USB overcurrent pin muxing on SoM layer. On DRC02 and PDK2 the USB overcurrent pin isn't connected, but a USB hub on the board takes care of the USB overcurrent instead. Therefore disable it there with the property disable-over-current.

* ARM: dts: imx6qdl-dhcom: Identify the PHY by ethernet-phy-id0007.c0f0Christoph Niedermaier2021-12-141-1/+2
| | | | | | | | | | | | | | | | | | Identify the PHY by its compatible ID value. In some cases during boot, the PHY needs to be reset to be accessible, but this is only possible if the PHY is recognized. In that case, the automatic detection of the PHY does not work and a static compatible ID value is need.

* ARM: dts: imx6qdl-dhcom: Align PHY reset timing with other DHCOM SoMsChristoph Niedermaier2021-12-141-2/+2
| | | | | | | | | | | | | | | | | | | | According to datasheet Microchip LAN8710A/LAN8710Ai DS00002164B [1] the reset should stay asserted for at least 100uS and software should wait at least 200nS. On other DHCOM SoMs with the SMSC LAN8710Ai PHY both reset delays are 500us. This should be plenty and for consistency, the i.MX6 SoM should also use these delays.

* ARM: dts: imx6qdl-dhcom: Split SoC-independent parts of DHCOM SOM and PDK2Christoph Niedermaier2021-08-091-0/+815
The DH electronics PDK2 can be populated with SoM with i.MX6S/DL/D/Q variants. Split the SoC-independent parts of the SoM and PDK2 into the imx6qdl-dhcom-*.dtsi and reduce imx6q-dhcom-pdk2.dts to example of adding i.MX6S/DL/D/Q variants of the SoM into a PDK2 carrier board.
