  To: linux-kernel
  Cc: Heiko Schocher, Shawn Guo, Sascha Hauer, linux-arm-kernel, devicetree

This patch add support for the imx6dl based aristainetos2 board
with following configuration:

CPU:   Freescale i.MX6DL rev1.1 at 792 MHz
MReset cause: POR
MBoard: aristaitenos2
DRAM:  1 GiB
NAND:  1024 MiB
MMC:   FSL_SDHC: 0, FSL_SDHC: 1
SF: Detected N25Q128A with page size 256 Bytes, erase size 64 KiB, total 16 MiB
Display: lb07wv8 (800x480)

As this board can used with 2 different display types, the
differences between them are extracted into 2 DTS files, and
the common settings are collected in a common file.

Signed-off-by: Heiko Schocher <hs@denx.de>

Changes in v2:
- add comments from Sascha Hauer:
  - remove "clock-frequency" property in i2c nodes
  - correct indentation in some pinctrl nodes
  - move pin settings out of "gpiogrp" where it was possible
    led pins not moved, as they used through sysfs

What are the differences between aristainetos2 and aristainetos board?

Add them as DTB target into arch/arm/boot/dts/Makefile.

GPL/X11 dual licence is suggested for new DTS files.  See
arch/arm/boot/dts/imx6sl-warp.dts for an example.

status = "okay" is mostly used in board level dts to enable device that
is by default disabled in <soc>.dtsi.  In your case here, it can just be
saved.

What is this?  I failed to find it in Documentation/devicetree/bindings/

Can be saved?

LinusW queued patch 5fcdf6a7ed95 ("pinctrl: imx: Allow parsing DT
without function nodes") on pinctrl tree for 4.2 merge window.  With
that, we can save one level of the sub-node.

> +		pinctrl_ipu1_1_80Ohm_clk: ipudisp1grp {

The '1' suffix after 'ipu1' is meaningless.  Please drop it.  Also, will
you use other pad configuration for CLK for this board?  Otherwise, the
suffix '_80Ohm_clk' can be saved too?

It seems the touch device is identical between
imx6dl-aristainetos2_4.dts and imx6dl-aristainetos2_7.dts.  Why don't
you put it into imx6qdl-aristainetos2.dtsi?

You included dt-bindings/gpio/gpio.h but did not use the macros?

The dma-names should be a property with string value.

Have a new line between nodes.

I suggest you put iomuxc node at the bottom of the file to improve the
readability of the file.

These pins should be configured by client device node, not the hog
group.

Provide a proper pad configuration value rather than 0x8000000.

aristainetos is a i.MX6 design with a proprietary form-factor and interface connector.
aristainetos2 is a SMARC compatible design.

Ah, yes, you are right, since commit:

commit a02bb401f8ae264be782ee57d98bdd99f14c8022
Author: Robin Gong <b38343@freescale.com>

     spi: imx: use pio mode for i.mx6dl

this is not longer needed, I remove (and test) it.

The node name with the example in bindings doc
Documentation/devicetree/bindings/input/atmel,maxtouch.txt seems
perfectly fine to me.

Okay, I missed that.

This was meant to be a temporary solution to connect a drm_panel to the
parallel-display when the of-graph bindings were not yet available.
I'd very much prefer to switch to the common of-graph bindings similarly
to the LDB driver instead. Could you check if this would work for you:

From: Philipp Zabel <p.zabel@pengutronix.de>
Subject: [PATCH] drm/imx: parallel-display: fix drm_panel support

The parallel-display driver used an undocumented, non-standard property
"fsl,panel" to optionally associate with a drm_panel device. This patch
fixes the driver to use the OF graph bindings, just as the LDB driver:

    parallel-display {
            compatible = "fsl,imx-parallel-display";
            ...

            port@1 {
                    reg = <1>;

                    parallel_out: endpoint {
                            remote_endpoint = <&panel_in>;
                    };
            };
    };

    panel {
            ...

            port {
                    panel_in: endpoint {
                            remote-endpoint = <&parallel_out>;
                    };
            };
    };

Yes, your patch works for me (with appropriate changes in the dts file)
You can add my
Tested-by: Heiko Schocher <hs@denx.de>
for this patch, thanks!

@Shawn: How do I proceed now with my patch for the aristainetos2 board
         support? Should I base my v3 of the aristainetos2 on this patch,
         or should I wait with this change, until the patch from Philipp
         is accepted and post a follow up?

bye,
Heiko

Thank you, I've posted that parallel-display patch and will try to queue
it for v4.2 when it gets accepted.
