2018-09-15drm: rcar-du: Write ESCR and OTAR as CRTC registersJacopo Mondi2-7/+6
The ESCR and OTAR registers exist in each DU channel, but at different offsets for odd and even channels. This led to usage of the group register access API to write them, with offsets macros named ESCR/OTAR and ESCR2/OTAR2 for the first and second ESCR/OTAR register in the group respectively. The names are confusing as it suggests that the ESCR/OTAR registers for DU0 and DU2 are taken into account, especially with writes performed to the group register access API. Rename the offsets to ESCR/OTAR02 and ESCR/OTAR13, and use the CRTC register access API to clarify the code. The offsets values are updated accordingly.

2018-09-15drm: rcar-du: Improve non-DPLL clock selectionJacopo Mondi1-31/+54
DU channels not equipped with a DPLL use an SoC internal (provided by the CPG) or external clock source combined with a DU internal divider to generate the desired output dot clock frequency. The current clock selection procedure does not fully exploit the ability of external clock sources to generate the exact dot clock frequency by themselves, but relies instead on tuning the internal DU clock divider only, resulting in a less precise clock generation process. When possible, and desirable, ask the external clock source for the exact output dot clock frequency, and select the clock source that produces the frequency closest to the desired output dot clock. This patch specifically targets platforms (like Salvator-X[S] and ULCBs) where the DU's input dotclock.in is generated by the versaclock VC5 clock source, which is capable of generating the exact rate the DU needs as pixel clock output. This patch fixes higher resolution modes which requires an high pixel clock output currently not working on non-HDMI DU channel (such as 1920x1080@60Hz on the VGA output).
