phy: qcom: qmp-combo: Switch from V6 to V6 N4 register offsets

2024-06-03T14:00:47+00:00

Currently, none of the X1E80100 supported boards upstream have enabled
DP. As for USB, the reason it is not broken when it's obvious that the
offsets are wrong is because the only difference with respect to USB is
the difference in register name. The V6 uses QPHY_V6_PCS_CDR_RESET_TIME
while V6 N4 uses QPHY_V6_N4_PCS_RX_CONFIG. Now, in order for the DP to
work, the DP serdes tables need to be added as they have different
values for V6 N4 when compared to V6 ones, even though they use the same
V6 offsets. While at it, switch swing and pre-emphasis tables to V6 as
well.

phy: qcom-qmp: pcs: Add missing v6 N4 register offsets

2024-06-03T14:00:47+00:00

The new X1E80100 SoC bumps up the HW version of QMP phy to v6 N4 for
combo USB and DP PHY.  Currently, the X1E80100 uses the pure V6 PCS
register offsets, which are different. Add the offsets so the
mentioned platform can be fixed later on. Add the new PCS offsets
in a dedicated header file.

phy: qcom-qmp: qserdes-txrx: Add missing registers offsets

2024-06-03T14:00:47+00:00

Currently, the x1e80100 uses pure V6 register offsets for DP part of the
combo PHY. This hasn't been an issue because external DP is not yet
enabled on any of the boards yet. But in order to enabled it, all these
new V6 N4 register offsets are needed. So add them.

phy: rockchip: fix CONFIG_TYPEC dependency

2024-04-17T14:33:01+00:00

The newly added driver causes a warning about missing dependencies
by selecting CONFIG_TYPEC unconditionally:

WARNING: unmet direct dependencies detected for TYPEC
  Depends on [n]: USB_SUPPORT [=n]
  Selected by [y]:
  - PHY_ROCKCHIP_USBDP [=y] && ARCH_ROCKCHIP [=y] && OF [=y]

WARNING: unmet direct dependencies detected for USB_COMMON
  Depends on [n]: USB_SUPPORT [=n]
  Selected by [y]:
  - EXTCON_RTK_TYPE_C [=y] && EXTCON [=y] && (ARCH_REALTEK [=y] || COMPILE_TEST [=y]) && TYPEC [=y]

Since that is a user-visible option, it should not really be selected
in the first place. Replace the 'select' with a 'depends on' as
we have for similar drivers.
