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 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 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
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

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

I've commented this on your v2 already. One of the Lucas's comments[1] about
this node was following:
"Get rid of this simple bus. It's not there in hardware and regulators
care board level components just like the nodes above and below."
It works for me(tm) with following Apalis dtsi[2] on 4.4.0-rc3+ from
arm-soc/for-next[3] with my changes based on this commit:

As Petr already mentioned, we should try to put these fixed regulators
directly under root node. In that case, we can drop the fake
simple-bus container node and save the artificial 'reg' property. The
regulators can be named in the following schema:
reg_xxx: regulator-xxx {
...

The device is disabled by default in imx6qdl.dtsi, so this is not
needed.

Shouldn't the node name be generic as just touchscreen? Or at least,
hyphen instead of underscore should be used in node name.

These function container nodes do not make too much sense now, and can
be dropped, since commit 5fcdf6a7ed95 (pinctrl: imx: Allow parsing DT
without function nodes).

I would like to see a consistent pinctrl group node naming schema, i.e.
xxxgrp. In any case, underscore shouldn't be used in node name.

I actually think one pinctrl node like the following is good enough,
with some necessary comments on the extra pins.
pinctrl_ecspi1: ecspi1grp {
fsl,pins = <
MX6QDL_PAD_CSI0_DAT6__ECSPI1_MISO 0x100b1
MX6QDL_PAD_CSI0_DAT5__ECSPI1_MOSI 0x100b1
MX6QDL_PAD_CSI0_DAT4__ECSPI1_SCLK 0x100b1
/* SPI1 cs */
MX6QDL_PAD_CSI0_DAT7__GPIO5_IO25 0x000b1
>;
};
If you consider this for all the following pinctrl nodes, I think the
iomuxc node will become a bit clean and clear.

As Petr already mentioned, we should try to put these fixed regulators
directly under root node. In that case, we can drop the fake
simple-bus container node and save the artificial 'reg' property. The
regulators can be named in the following schema:
reg_xxx: regulator-xxx {
...
}

The device is disabled by default in imx6qdl.dtsi, so this is not
needed.

Shouldn't the node name be generic as just touchscreen? Or at least,

These function container nodes do not make too much sense now, and can
be dropped, since commit 5fcdf6a7ed95 (pinctrl: imx: Allow parsing DT
without function nodes).

I would like to see a consistent pinctrl group node naming schema, i.e.
xxxgrp. In any case, underscore shouldn't be used in node name.

I actually think one pinctrl node like the following is good enough,
with some necessary comments on the extra pins.
pinctrl_ecspi1: ecspi1grp {
fsl,pins = <
MX6QDL_PAD_CSI0_DAT6__ECSPI1_MISO 0x100b1
MX6QDL_PAD_CSI0_DAT5__ECSPI1_MOSI 0x100b1
MX6QDL_PAD_CSI0_DAT4__ECSPI1_SCLK 0x100b1
/* SPI1 cs */
MX6QDL_PAD_CSI0_DAT7__GPIO5_IO25 0x000b1
>;
};
If you consider this for all the following pinctrl nodes, I think the
iomuxc node will become a bit clean and clear.

As Petr already mentioned, we should try to put these fixed regulators
directly under root node. In that case, we can drop the fake
simple-bus container node and save the artificial 'reg' property. The
regulators can be named in the following schema:
reg_xxx: regulator-xxx {
...
}

The device is disabled by default in imx6qdl.dtsi, so this is not
needed.

Shouldn't the node name be generic as just touchscreen? Or at least,
hyphen instead of underscore should be used in node name.

These function container nodes do not make too much sense now, and can
be dropped, since commit 5fcdf6a7ed95 (pinctrl: imx: Allow parsing DT

I would like to see a consistent pinctrl group node naming schema, i.e.
xxxgrp. In any case, underscore shouldn't be used in node name.

I actually think one pinctrl node like the following is good enough,
with some necessary comments on the extra pins.
pinctrl_ecspi1: ecspi1grp {
fsl,pins = <
MX6QDL_PAD_CSI0_DAT6__ECSPI1_MISO 0x100b1
MX6QDL_PAD_CSI0_DAT5__ECSPI1_MOSI 0x100b1
MX6QDL_PAD_CSI0_DAT4__ECSPI1_SCLK 0x100b1
/* SPI1 cs */
MX6QDL_PAD_CSI0_DAT7__GPIO5_IO25 0x000b1
>;
};
If you consider this for all the following pinctrl nodes, I think the
iomuxc node will become a bit clean and clear.

To be honest I don't remember the exact issues it caused. I just tried
again now with latest next-20160203 and besides slab being broken it
worked like a charm. So finally rid of it I got (;-p).

Looking more closely there is actually a proper binding document which
got added by Lee Jones:
commit 84e6de813b2d1bdb127943d3c8edf1c1afaa90da
Author: Lee Jones <lee.jones@linaro.org>
Date: Mon Nov 5 16:10:34 2012 +0100
Subject: Documentation: Describe bindings for STMPE Multi-Functional
Device driver
Documentation/devicetree/bindings/mfd/stmpe.txt
Required properties:
- compatible : "st,stmpe[811|1601|2401|2403]"
Sorry for the noise.

Yeah the STMPE driver was a common work between Rabin and
Luotao Fu who pitched in the 811 with touchscreen support.
Then Lee added the device tree stuff.
I know it's a bit confusing that the DT bindings for the whole shebang
is in bindings/mfd but it is also confusing to split them up, don't know
what is best really :(
