Subject: [PATCH v7 01/10] dt-bindings: imx6q-pcie: Add ref clock for i.MX95 PCIe RC
Previous reference clock of i.MX95 PCIe RC is on when system boot to
kernel. But boot firmware change the behavor, it is off when boot. So it
needs be turn on when it is used. Also it needs be turn off/on when suspend
and resume.
Add one ref clock for i.MX95 PCIe RC. Increase clocks' maxItems to 5 and
keep the same restriction with other compatible string.
