Hello,
This patch series has previously been posted as part of "[PATCH v2 0/7]
drm: mxsfb: Allow overriding bus width". I've split the DT bindings
conversion to a separate series as I believe they're ready, and Martin
has a patch that he would like to submit to the bindings.
All the patches have been acked, and changes to v2 are minor. Rob, could
you take this through your tree ?

Convert the mxsfb binding to YAML. The deprecated binding is dropped, as
neither the DT sources nor the driver support it anymore. The converted
binding is named fsl,lcdif.yaml to match the usual bindings naming
scheme.
The compatible strings are messy, and DT sources use different kinds of
combination of documented and undocumented values. Keep it simple for
now, and update the example to make it valid. Aligning the binding with
the existing DT sources will be performed separately.

-* Freescale MXS LCD Interface (LCDIF)
-
-New bindings:
-=============
-Required properties:
-- compatible: Should be "fsl,imx23-lcdif" for i.MX23.
- Should be "fsl,imx28-lcdif" for i.MX28.
- Should be "fsl,imx6sx-lcdif" for i.MX6SX.
- Should be "fsl,imx8mq-lcdif" for i.MX8MQ.
-- reg: Address and length of the register set for LCDIF
-- interrupts: Should contain LCDIF interrupt
-- clocks: A list of phandle + clock-specifier pairs, one for each
- entry in 'clock-names'.
-- clock-names: A list of clock names. For MXSFB it should contain:
- - "pix" for the LCDIF block clock
- - (MX6SX-only) "axi", "disp_axi" for the bus interface clock
-
-Required sub-nodes:
- - port: The connection to an encoder chip.
-
-Example:
-
- lcdif1: display-controller@2220000 {
- compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";
- reg = <0x02220000 0x4000>;

- Should be "fsl,imx28-lcdif" for i.MX28.
-- reg: Address and length of the register set for LCDIF
-- interrupts: Should contain LCDIF interrupts
-- display: phandle to display node (see below for details)

-* display node
-
-Required properties:
-- bits-per-pixel: <16> for RGB565, <32> for RGB888/666.
-- bus-width: number of data lines. Could be <8>, <16>, <18> or <24>.
-
-Required sub-node:
-- display-timings: Refer to binding doc display-timing.txt for details.

* [PATCH v3 2/3] dt-bindings: display: mxsfb: Add and fix compatible strings

Additional compatible strings have been added in DT source for the
i.MX6SL, i.MX6SLL, i.MX6UL and i.MX7D without updating the bindings.
Most of the upstream DT sources use the fsl,imx28-lcdif compatible
string, which mostly predates the realization that the LCDIF in the
i.MX6 and newer SoCs have extra features compared to the i.MX28.
Update the bindings to add the missing compatible strings, with the
correct fallback values. This fails to validate some of the upstream DT
sources. Instead of adding the incorrect compatible fallback to the
binding, the sources should be updated separately.

Better to go thru drm-misc-next given other changes coming, so I applied
