Subject: ARM: dts: lpc18xx: add cgu and ccu clock-controller nodes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ba2db535a99dc004ab6b7952625029ec196514b9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: lpc18xx: add cgu and ccu clock-controller nodes

Add CGU and CCU clock-controller nodes for lpc18xx together with
the fixed input clocks. Also remove the temporary fixed-factor
pll1 clock from both lpc18xx and lpc4350-hitex-eval DTS now that
proper clock drivers are inplace.
