[PATCH] drm/stm: ltdc: use crtc_mode_fixup to update adjusted_mode clock

2018-01-25 Thread Philippe Cornu
There is a difference between the panel/bridge requested pixel clock value and the real one due to the hw platform clock preciseness (pll, dividers...). This patch updates the adjusted_mode clock value with the real hw clock value so then attached encoder & connector can use it for precise timing c
