[PATCH 6.0 0611/1073] dt-bindings: imx6q-pcie: Fix clock names for imx6sx and imx8mq

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Serge Semin <Sergey.Semin@xxxxxxxxxxxxxxxxxxxx>

[ Upstream commit b8a83e600bdde93e7da41ea3204b2b3832a3c99b ]

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.
