[PATCH 1/3] dt-bindings: mfd: st,stmpe: add deprecated properties

[Frank.Li]

From: Frank Li <Frank.Li@nxp.com>

Add deprecated properties st,sample-time, st,sample-time, st,mod-12b and
st,ref-sel. The both driver drivers/mfd/stmpe.c and
drivers/input/touchscreen/stmpe-ts.c parse these information. Some dts
put these properties under mfd, but some put these under child node
sample_ts.

Allow these properties put under sample_ts and mark as deprecated to fix
below CHECK_DTBS warnings:
  arch/arm/boot/dts/nxp/imx/imx6q-novena.dtb: stmpe811@44 (st,stmpe811): touchscreen: Unevaluated properties are not allowed ('st,adc-freq', 'st,mod-12b', 'st,ref-sel', 'st,sample-time' were unexpected)
        from schema $id: http://devicetree.org/schemas/mfd/st,stmpe.yaml

Why is this attached to submission:

  [PATCH 0/3] ARM: dts: imx: cleanup st,stmpe touch screen related CHECK_DTB warings

And where are the other 2 patches?

Pleas send new patches as a new thread.

Never attach a new patch to an existing thread.

[PATCH 2/3] dt-bindings: mfd: st,stmpe: let interrupt property optional

[Frank.Li]

From: Frank Li <Frank.Li@nxp.com>

Not all boards connect irq lines. So mark interrupt property optional.

Fix below CHECK_DTBS warnings:
  arch/arm/boot/dts/nxp/imx/imx6dl-phytec-pbab01.dtb: stmpe@41 (st,stmpe811): 'oneOf' conditional failed, one must be fixed:
        'interrupts' is a required property
        'interrupts-extended' is a required property
