Subject[PATCH v7 01/20] dt-bindings: imx6q-pcie: Fix clock names for imx6sx and imx8mq
Date
Originally as it was defined the legacy bindings the pcie_inbound_axi and
pcie_aux clock names were supposed to be used in the fsl,imx6sx-pcie and
fsl,imx8mq-pcie devices respectively. But the bindings conversion has been
incorrectly so now the fourth clock name is defined as "pcie_inbound_axi
for imx6sx-pcie, pcie_aux for imx8mq-pcie", which is completely wrong.
Let's fix that by conditionally apply the clock-names constraints based on
the compatible string content.

Fixes: 751ca492f131 ("dt-bindings: PCI: imx6: convert the imx pcie controller to dtschema")

Changelog v5:
- This is a new patch added on the v5 release of the patchset.

Changelog v7:
- Move the allOf clause to the bottom of the bindings. (@Krzysztof)
- Get back the names to the clock-names property and make sure the
platform-specific name constraint is applied in the allOf clause.
(@Rob)
