-Subject: OMAP: Improve pixel clock configuration
-X-Git-Url: http://git.mansr.com/?p=linux-omap;a=commitdiff_plain;h=01c2d720e59c291de9eb21eb65225f2f215fef84

-OMAP: Improve pixel clock configuration
-
-This sets the DSS1_ALWON_FCLK clock as close as possible to a
-multiple of the requested pixel clock, while keeping it below
-the 173MHz limit.
-
-Due to of the structure of the clock tree, dss1_alwon_fck cannot
-be set directly, and we must use dpll4_m4_ck instead.
