  668.  * DOC: DPIO
  669.  *
  670.  * VLV and CHV have slightly peculiar display PHYs for driving DP/HDMI
  671.  * ports. DPIO is the name given to such a display PHY. These PHYs
  672.  * don't follow the standard programming model using direct MMIO
  673.  * registers, and instead their registers must be accessed trough IOSF
  674.  * sideband. VLV has one such PHY for driving ports B and C, and CHV
  675.  * adds another PHY for driving port D. Each PHY responds to specific
  676.  * IOSF-SB port.
  677.  *
  678.  * Each display PHY is made up of one or two channels. Each channel
  679.  * houses a common lane part which contains the PLL and other common
  680.  * logic. CH0 common lane also contains the IOSF-SB logic for the
  681.  * Common Register Interface (CRI) ie. the DPIO registers. CRI clock
  682.  * must be running when any DPIO registers are accessed.
  683.  *
  684.  * In addition to having their own registers, the PHYs are also
  685.  * controlled through some dedicated signals from the display
  686.  * controller. These include PLL reference clock enable, PLL enable,
  687.  * and CRI clock selection, for example.
  688.  *
  689.  * Eeach channel also has two splines (also called data lanes), and
  690.  * each spline is made up of one Physical Access Coding Sub-Layer
  691.  * (PCS) block and two TX lanes. So each channel has two PCS blocks
  692.  * and four TX lanes. The TX lanes are used as DP lanes or TMDS
  693.  * data/clock pairs depending on the output type.
  694.  *
  695.  * Additionally the PHY also contains an AUX lane with AUX blocks
  696.  * for each channel. This is used for DP AUX communication, but
  697.  * this fact isn't really relevant for the driver since AUX is
  698.  * controlled from the display controller side. No DPIO registers
  699.  * need to be accessed during AUX communication,
  700.  *
  701.  * Generally the common lane corresponds to the pipe and
  702.  * the spline (PCS/TX) corresponds to the port.
  703.  *
  704.  * For dual channel PHY (VLV/CHV):
  705.  *
  706.  *  pipe A == CMN/PLL/REF CH0
  707.  *
  708.  *  pipe B == CMN/PLL/REF CH1
  709.  *
  710.  *  port B == PCS/TX CH0
  711.  *
  712.  *  port C == PCS/TX CH1
  713.  *
  714.  * This is especially important when we cross the streams
  715.  * ie. drive port B with pipe B, or port C with pipe A.
  716.  *
  717.  * For single channel PHY (CHV):
  718.  *
  719.  *  pipe C == CMN/PLL/REF CH0
  720.  *
  721.  *  port D == PCS/TX CH0
  722.  *
  723.  * Note: digital port B is DDI0, digital port C is DDI1,
  724.  * digital port D is DDI2
