Subject: IPQ40xx: clk: Use dt-bindings instead of hardcoding
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=5ae15415c12c330ef3cd5d8c13bdadf5afb3db7a;p=u-boot.git

IPQ40xx: clk: Use dt-bindings instead of hardcoding

Its common to use dt-bindings instead of hard-coding clocks or resets.
So lets use the imported Linux GCC bindings on IPQ40xx target.
