+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.
