2018-01-29drm/stm: ltdc: use crtc_mode_fixup to update adjusted_mode clockPhilippe CORNU1-10/+25
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 computations.

2018-01-09drm/bridge/synopsys: stop clobbering drvdataBrian Norris1-5/+9
Bridge drivers/helpers shouldn't be clobbering the drvdata, since a parent driver might need to own this. Instead, let's return our 'dw_mipi_dsi' object and have callers pass that back to us for removal.
