Subject: arm64: dts: ti: k3-j784s4-j742s2-evm-common: Enable ACSPCIE0 output for PCIe1
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e3dfcf482d0787a5882f10a33daa4c1ec62b87d2;p=users%2Fjedix%2Flinux-maple.git

arm64: dts: ti: k3-j784s4-j742s2-evm-common: Enable ACSPCIE0 output for PCIe1

The PCIe reference clock required by the PCIe Endpoints connected to the
PCIe connector corresponding to the PCIe1 instance of PCIe on J784S4-EVM
and J742S2-EVM is driven by the ACSPCIE0 module. Add the device-tree
support for enabling the same.
