This patch series adds support for Toradex Apalis iMX6Q/D SoM module [1] and
Ixora carrier board [2].
Petr Štetiar 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 Štetiar's
"PCI: imx6: Fix reset-gpio to work with active low GPIO" fix [4] is needed.

Changes in v5:
- finally get rid of regulators simple bus as suggested by Lucas, Petr and Shawn
- use reg_xxx: regulator-xxx naming scheme as suggested by Shawn
- get rid of disabled hdmi node as suggested by Shawn
- have a new line between properties and sub-node as suggested by Shawn
- get rid of disabled usbh1 node as suggested by Shawn
- drop iomux/pinctrl function container nodes as suggested by Shawn
- added new lines between nodes as suggested by Shawn
- use consistent pinctrl group node naming schema xxxgrp as suggested by Shawn
- further clean-up and re-order iomux/pinctrl stuff
- configure eMMC reset as required once fast boot mode is used
- properly set usdhc1, usdhc2 and usdhc3 vqmmc-supply rather than vmmc-supply we previously set leading to wrong signal voltage being reported
- drop iomux/pinctrl function container node as suggested by Shawn
- added new line between nodes as suggested by Shawn
- use consistent pinctrl group node naming schema xxxgrp as suggested by Shawn
- replace the gpio-key,wakeup property with the generic wakeup-source one as suggested by Shawn
- drop regulators function container node and use simple label reference to enable USB VBUS' as suggested by Shawn
Changes in v4:
- integrated review feedback from Fabio
Changes in v3:
- integrated review feedback from Petr
- integrated review feedback from Stefan
- move I2C DDC enablement and assignement handling into carrier board DTS where it belongs
- move CAN nodes up a little to keep the alphabetical order
- added an explanatory comment about PWR_I2C usage
- integrated review feedback from Petr
- integrated review feedback from Stefan
- fix comment concerning Apalis GPIO usage as GPIO7 is only used for PCIe switch reset on Apalis Evaluation board
- move I2C DDC handling into carrier board DTS where it belongs
- simplify RTC alias
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
- clarify exact Apalis iMX6Q/D SoM type in cover letter

Changes in v5:
- drop iomux/pinctrl function container node as suggested by Shawn
- added new line between nodes as suggested by Shawn
- use consistent pinctrl group node naming schema xxxgrp as suggested by Shawn
- replace the gpio-key,wakeup property with the generic wakeup-source one as suggested by Shawn
- drop regulators function container node and use simple label reference to enable USB VBUS' as suggested by Shawn
Changes in v4: None
Changes in v3:
- integrated review feedback from Petr
- integrated review feedback from Stefan
- fix comment concerning Apalis GPIO usage as GPIO7 is only used for PCIe switch reset on Apalis Evaluation board
- move I2C DDC handling into carrier board DTS where it belongs
- simplify RTC alias
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

Practically you don't need this overcomplicated GPIO-based bitbanging
to emulate I2C, because the DW HDMI controller has a reduced I2C
controller on board, you may take a look at its support published here:
http://www.spinics.net/lists/dri-devel/msg116308.html
To utilize it the pads should be set to HDMI function instead of
I2C or GPIO.

Thanks for the notification! I guess we'd also have to remove...
+&hdmi {
+ ddc-i2c-bus = <&i2cddc>;
...this line...
+ status = "okay";
+};
+
+&i2cddc {
+ status = "okay";
+};
and this from arch/arm/boot/dts/imx6q-apalis-ixora.dts.
