Subject: stm32mp1: clk: use gd to store frequency information
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=4de076ed0958d98168820d5b2b5d96c16f928605;p=u-boot.git

stm32mp1: clk: use gd to store frequency information

Use existing gd structure to store frequency information
which can be used in drivers or arch without new request.
