Subject: ARM: mx28: set proper parent for lcdif clock
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=12b90f8a2ce4d913d9080dcd6b6c329db00cbbeb;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ARM: mx28: set proper parent for lcdif clock

Most likely, the LCD panel on mx28 platform will require a pixel
clock higher than ref_xtal_clk (24 MHz), so the patch initializes
the parent of lcdif clock as ref_pix_clk.
