commit 025a6f7448f7bb5f4fceb62498ee33d89ae266bb upstream.

Commit 5abed58a8bde ("phy: qcom: qmp-combo: Fix VCO div offset on v3")
fixed a regression introduced in 6.5 by making sure that the correct
offset is used for the DP_PHY_VCO_DIV register on v3 hardware.

Unfortunately, that fix instead broke DisplayPort on v5_5nm and v6
hardware as it failed to add the corresponding offsets also to those
register tables.

phy: qcom: qmp-combo: Fix VCO div offset on v3

commit 5abed58a8bde6d349bde364a160510b5bb904d18 upstream.

Commit ec17373aebd0 ("phy: qcom: qmp-combo: extract common function to

phy: qcom: qmp-combo: Fix VCO div offset on v3

commit 5abed58a8bde6d349bde364a160510b5bb904d18 upstream.

Commit ec17373aebd0 ("phy: qcom: qmp-combo: extract common function to
setup clocks") changed the offset that is used to write to
DP_PHY_VCO_DIV from QSERDES_V3_DP_PHY_VCO_DIV to
QSERDES_V4_DP_PHY_VCO_DIV. Unfortunately, this offset is different
between v3 and v4 phys:

#define QSERDES_V3_DP_PHY_VCO_DIV 0x064
#define QSERDES_V4_DP_PHY_VCO_DIV 0x070

meaning that we write the wrong register on v3 phys now. Add another
generic register to 'regs' and use it here instead of a version specific
define to fix this.

This was discovered after Abhinav looked over register dumps with me
from sc7180 Trogdor devices that started failing to light up the
external display with v6.6 based kernels. It turns out that some
monitors are very specific about their link clk frequency and if the
default power on reset value is still there the monitor will show a
blank screen or a garbled display. Other monitors are perfectly happy to
get a bad clock signal.

Oddly the value being 0x4c or 0x5c doesn't seem to matter for me, so I

not good to write to the wrong register space, and maybe some other

phy: qcom-qmp-combo: simplify clock handling

For the existing PHYs for new binding we are going to drop ref_clk_src
clock and always use ref clock. Rather than introducing additional code
to handle legacy vs current bindings (and clock names), use
devm_clk_bulk_get_optional() when new bindings are used and
devm_clk_bulk_get_all() when legacy bindings are in place.

phy: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

It seems the commit a2e927b0e50d ("phy: qcom-qmp-combo: Add sc8280xp
USB/DP combo phys") contained a typo for selecting bias0_en values.
First, bias0_en and bias1_en are expected to be symmetrical, and then
the vendor driver also uses `flipped : 0x3E : 0x15` statement for
bias0_en. Correct bias0_en programming to follow this.
