Subject: arm64: dts: marvell: armada-37xx: add syscon compatible to NB clk node
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=6c2f97f3887f5bd359947d0f12830330c3be7a87;p=linux-block.git

arm64: dts: marvell: armada-37xx: add syscon compatible to NB clk node

commit 1d88358a89dbac9c7d4559548b9a44840456e6fb upstream.

Add "syscon" compatible to the North Bridge clocks node to allow the
cpufreq driver to access these registers via syscon API.

This is needed for a fix of cpufreq driver.
