/**
 * DOC: DPIO
 *
 * VLV, CHV and BXT 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 on VLV/CHV the common lane corresponds to the pipe and
 * the spline (PCS/TX) corresponds 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
 *
 * On BXT the entire PHY channel corresponds to the port. That means
 * the PLL is also now associated with the port rather than the pipe,
 * and so the clock needs to be routed to the appropriate transcoder.
 * Port A PLL is directly connected to transcoder EDP and port B/C
 * PLLs can be routed to any transcoder A/B/C.
 *
 * Note: DDI0 is digital port B, DD1 is digital port C, and DDI2 is
 * digital port D (CHV) or port A (BXT).
