DPIO is the name given to such a display PHY. These PHYs + * don't follow the standard programming model using direct MMIO + * registers, and instead their registers must be accessed trough IOSF + * sideband. VLV has one such PHY for driving ports B and C, and CHV + * adds another PHY for driving port D.

Each channel + * houses a common lane part which contains the PLL and other common + * logic. CH0 common lane also contains the IOSF-SB logic for the + * Common Register Interface (CRI) ie. the DPIO registers. CRI clock + * must be running when any DPIO registers are accessed. + * + * In addition to having their own registers, the PHYs are also + * controlled through some dedicated signals from the display + * controller. These include PLL reference clock enable, PLL enable, + * and CRI clock selection, for example. + * + * Eeach channel also has two splines (also called data lanes), and + * each spline is made up of one Physical Access Coding Sub-Layer + * (PCS) block and two TX lanes. So each channel has two PCS blocks + * and four TX lanes. The TX lanes are used as DP lanes or TMDS + * data/clock pairs depending on the output type. + * + * Additionally the PHY also contains an AUX lane with AUX blocks + * for each channel. This is used for DP AUX communication, but + * this fact isn't really relevant for the driver since AUX is + * controlled from the display controller side.
