Subject: ARM: dts: add clock support for Airoha EN7523
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e0c5341acdbeb5c900f3204cf279153c1c8b7433;p=linux.git

ARM: dts: add clock support for Airoha EN7523

This driver only registers fixed rate clocks, since the clocks are fully
initialized by the boot loader and should not be changed later, according
to Airoha.
