Subject: mediatek: mt7988: add missing clock for PCIe ports
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2b25f66d0a61edf7b9411432b6c920ad00f0f28b;p=openwrt%2Fstaging%2Fnbd.git

mediatek: mt7988: add missing clock for PCIe ports

Add missing CLK_TOP_PEXTP_Px_SEL clock for each of the 4 PCIe interfaces
of the MT7988 SoC. Without that clock PCIe doesn't work reliable.
