    749  * DOC: DPIO
    750  *
    751  * VLV, CHV and BXT have slightly peculiar display PHYs for driving DP/HDMI
    752  * ports. DPIO is the name given to such a display PHY. These PHYs
    753  * don't follow the standard programming model using direct MMIO
    754  * registers, and instead their registers must be accessed trough IOSF
    755  * sideband. VLV has one such PHY for driving ports B and C, and CHV
    756  * adds another PHY for driving port D. Each PHY responds to specific
    757  * IOSF-SB port.
    758  *
    759  * Each display PHY is made up of one or two channels. Each channel
    760  * houses a common lane part which contains the PLL and other common
    761  * logic. CH0 common lane also contains the IOSF-SB logic for the
    762  * Common Register Interface (CRI) ie. the DPIO registers. CRI clock
    763  * must be running when any DPIO registers are accessed.
    764  *
    765  * In addition to having their own registers, the PHYs are also
    766  * controlled through some dedicated signals from the display
    767  * controller. These include PLL reference clock enable, PLL enable,
    768  * and CRI clock selection, for example.
    769  *
    770  * Eeach channel also has two splines (also called data lanes), and
    771  * each spline is made up of one Physical Access Coding Sub-Layer
    772  * (PCS) block and two TX lanes. So each channel has two PCS blocks
    773  * and four TX lanes. The TX lanes are used as DP lanes or TMDS
    774  * data/clock pairs depending on the output type.
    775  *
    776  * Additionally the PHY also contains an AUX lane with AUX blocks
    777  * for each channel. This is used for DP AUX communication, but
    778  * this fact isn't really relevant for the driver since AUX is
    779  * controlled from the display controller side. No DPIO registers
    780  * need to be accessed during AUX communication,
    781  *
    782  * Generally on VLV/CHV the common lane corresponds to the pipe and
    783  * the spline (PCS/TX) corresponds to the port.
    784  *
    785  * For dual channel PHY (VLV/CHV):
    786  *
    787  *  pipe A == CMN/PLL/REF CH0
    788  *
    789  *  pipe B == CMN/PLL/REF CH1
    790  *
    791  *  port B == PCS/TX CH0
    792  *
    793  *  port C == PCS/TX CH1
    794  *
    795  * This is especially important when we cross the streams
    796  * ie. drive port B with pipe B, or port C with pipe A.
    797  *
    798  * For single channel PHY (CHV):
    799  *
    800  *  pipe C == CMN/PLL/REF CH0
    801  *
    802  *  port D == PCS/TX CH0
    803  *
    804  * On BXT the entire PHY channel corresponds to the port. That means
    805  * the PLL is also now associated with the port rather than the pipe,
    806  * and so the clock needs to be routed to the appropriate transcoder.
    807  * Port A PLL is directly connected to transcoder EDP and port B/C
    808  * PLLs can be routed to any transcoder A/B/C.
    809  *
    810  * Note: DDI0 is digital port B, DD1 is digital port C, and DDI2 is
    811  * digital port D (CHV) or port A (BXT).
