X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b1ff3231b2d4197ef5024f9c57ffc6cfa562590c;p=linux-beck.git

phy: omap-usb2: Fix missing clk_prepare call when using old dt name

Current code does not call clk_prepare(phy->optclk) when using the old
usb_otg_ss_refclk960m name. Fix it.
