[PATCH 0/4] ARM: mxs: Various Crystalfontz DT additions

[Maxime Ripard]

Hi,

Here is a patchset that adds support for two new Crystalfontz boards, add
enable the USB port on the CFA-10036, and fix the chip select pin number for
the 10049. 

Thanks,
Maxime

The patches all look good, just one trivial comment about the fragment above:

There is already a "usb0" label in the imx28.dtsi file for the same
node. When you refer to the node from a board.dts file, either leave
out the redundant label, or use it to simplify the statements above
to the brief version:

	&usb0 {
		pinctrl-names = "default";
		pinctrl-0 = <&usb0_otg_cfa10036>;
		status = "okay";
	};

Yeah, I moved all imx board level dts files to use this.  But I was told
by Olof that the change does not gain too much and looks like a churn.
That's why I haven't made the same move for mxs.  So I will remove the
redundant label when applying this patch.

I would have the label stay there, because I found it's there like a
comment telling the controller instance.

[PATCH 2/4] ARM: cfa10049: Switch the chip select pin of the LCD controller

[Maxime Ripard]

From: Brian Lilly <brian@crystalfontz.com>

The early prototypes had the chip select pin for the LCD controller
wired on the GPIO 3-23, while the production run of the CFA-10049 have
this chip select on the GPIO 3-5.

[PATCH 3/4] ARM: mxs: dt: Add the Crystalfontz CFA-10055 device tree

[Maxime Ripard]

From: Brian Lilly <brian@crystalfontz.com>

The CFA-10055 is yet another breakout board for the CFA-10036, and is
basically a CFA-10037, with the screen and LCD controller found on the
CFA-10049.

Maybe this could be something like:

	else if (of_machine_is_compatible("crystalfontz,cfa10036"))
		crystalfontz_init();

with crystalfontz_init() something like:

	if (mac0 has status = "okay")
		update_fec_mac_prop(OUI_CRYSTALFONTZ);

This way, for all Crystalfontz boards that have an Ethernet interface,
it would call update_fec_mac_prop() without having to update mach-mxs.c
every time.

(Of course, this is based on the assumption that all Crystalfontz .dts
files have "crystalfontz,cfa10036" in their compatible string list)

Best regards,

Thomas

[PATCH 4/4] ARM: mxs: dt: Add Crystalfontz CFA-10057 device tree

[Maxime Ripard]

From: Brian Lilly <brian@crystalfontz.com>

The CFA-10057 is a breakout board for the CFA-10036 that has Ethernet,
USB and a 4.3" LCD screen on it.
