/**

 * DOC: DPIO

 *

 * VLV and CHV have slightly peculiar display PHYs for driving DP/HDMI

 * ports. 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 PHY responds to specific

 * IOSF-SB port.

 *

 * Each display PHY is made up of one or two channels. 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. No DPIO registers

 * need to be accessed during AUX communication,

 *

 * Generally the common lane corresponds to the pipe and

 * the spline (PCS/TX) correponds to the port.

 *

 * For dual channel PHY (VLV/CHV):

 *

 *  pipe A == CMN/PLL/REF CH0

 *

 *  pipe B == CMN/PLL/REF CH1

 *

 *  port B == PCS/TX CH0

 *

 *  port C == PCS/TX CH1

 *

 * This is especially important when we cross the streams

 * ie. drive port B with pipe B, or port C with pipe A.

 *

 * For single channel PHY (CHV):

 *

 *  pipe C == CMN/PLL/REF CH0

 *

 *  port D == PCS/TX CH0

 *

 * Note: digital port B is DDI0, digital port C is DDI1,

 * digital port D is DDI2
