Subject: OMAPDSS: DSI: remove clkin from dsi_clock_info
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3640d9fa7afa02940873d7d4c6c22915320d2a77;p=linux-beck.git

OMAPDSS: DSI: remove clkin from dsi_clock_info

struct dsi_clock_info contains clkin field, which is the rate of the
PLL's input clock. This field is not needed, as it can be easily
retrieved by using the clk_get_rate().

This patch removes the clkin field.
