Added programming phy layer for CHV based on "Application note for 1273
CHV Display phy".
v2: Rebase the code and do some cleanup.
v3: Rework based on Ville review.
-Fix the macro where the ch info need to swap, and add parens to ?
operator.
-Fix wrong bit define for DPIO_PCS_SWING_CALC_0 and
DPIO_PCS_SWING_CALC_1 and rename for meaningful.
-Add some comments for CHV specific DPIO registers.
-Change the dp margin registery value to decimal to align with the
doc.
-Fix the not clearing some value in vlv_dpio_read before write again.
-Create new hdmi/dp encoder function for chv instead of share with
valleyview.
v4: Rebase the code after rename the DPIO registers define and upstream
change.
Based on Ville review.
-For unique transition scale selection, after Ville point out, look
like the doc might wrong for the bit 26. Use bit 27 for ch0 and
ch1.
-Break up some dpio write value into two/three steps for readability.
-Remove unrelated change.
-Add some shift define for some registers instead just give the hex
value.
-Fix a bug where write to wrong VLV_TX_DW3.
v5: Based on Ville review.
- Move tx lane latency optimal setting from chv_dp_pre_pll_enable to
chv_pre_enable_dp, and chv_hdmi_pre_pll_enable to
chv_hdmi_pre_enable respectively.
- Fix typo in one margin_reg_value for DP_TRAIN_VOLTAGE_SWING_400.
- Clear DPIO_TX_UNIQ_TRANS_SCALE_EN for DP and HDMI.
- Mask the old deemph and swing bits for hdmi.
v6: Remove stub for pre_pll_enable for dp and hdmi.
