For various revision of chipset if the signal pattern is changed for every board, then the phy setting need to be updated correspondingly by measuring the signal. With the hdmiphy settings fixed in the driver the only way currently is to either add a new structure or add compile time option. To avoid this, we can move the same to dt, wherin we can have different dt files for every revision. This patchset can be considered as an initiative towards achieving the same for exynos 5250 and can be later extended to future chipsets. Also this patchset moves the entire structure to dt file as-is in the driver and hence we can find all the hex values, which are not logically explained similar to driver.
