Subject: rockchip: video: mipi: Fix phy frequency setting
X-Git-Url: http://git.dujemihanovic.xyz/html/index.html?a=commitdiff_plain;h=4c2808fd06c3f75df302af6a1354f3ec12278980;p=u-boot.git

rockchip: video: mipi: Fix phy frequency setting

There was an incorrect check when looping and finding the first
fast enough frequency in the freq_rang table. The code did
actually return the first that was either exactly correct or
too slow.
