[PATCH v2 0/2] ARM: dts: imx6: Add support for Toradex Apalis iMX6Q/D SoM/Ixora carrier board

[Marcel Ziswiler]

This patch series adds support for Toradex Apalis iMX6Q/D SoM module [1] and
Ixora carrier board [2].

Petr Åtetiar has simply taken content of DTSes from Toradex's Git tree [3],
removed not mainlined stuff and fixed all errors returned by checkpatch script.

Please note that RESET_MOCI# used as mini-PCIe PERST# is not directly
GPIO1_IO28 but rather inverted (e.g. active-high and ored with RESETBMCU coming
off the PMIC but that is not relevant in this context). As changing the
reset-gpio polarity wasn't previously supported Petr Åtetiar's
"PCI: imx6: Fix reset-gpio to work with active low GPIO" fix [4] is needed.

Changes in v2:
- clarify exact Apalis iMX6Q/D SoM type in cover letter
- clarify exact Apalis iMX6Q/D module type and Ixora carrier board in model
  node
- got rid of obsolete mmc aliases
- working SGTL5000 audio/sound integration
- working STMPE811 touch screen controller integration
- integrated review feedback from Lucas
- left and even added some more comments as I don't see why putting any
  explanatory comments in dts' should be such a bad thing to do
- completely got rid of the memory node as that is something typically filled
  in by the boot loader e.g. U-Boot
- without the regulators simple-bus it no longer boots
- even though we supposedly shipped a few hundred V1.0a modules drop DCE UART
  support for now and simplify file layout
- replaced obsolete no-1-8-v by mainline supported voltage-ranges = <3300 3300>
  usdhc property and yes card detects are indeed active low (;-p)
- integrated review feedback from Stefan
- fixed Ethernet PHY reset & interrupt (requires Micrel PHY driver to be
  enabled)
- fixed HDMI DDC (requires GPIO-based bitbanging I2C to be enabled)
- fixed SPDIF
