Ensure CONFIG_PHY_ROCKCHIP_SAMSUNG_HDPTX depends on CONFIG_COMMON_CLK to
fix the following link errors when compile testing some random kernel
configurations:
m68k-linux-ld: drivers/phy/rockchip/phy-rockchip-samsung-hdptx.o: in function `rk_hdptx_phy_clk_register':

Compile testing configurations without REGMAP support enabled results in
a bunch of errors being reported:
../drivers/phy/rockchip/phy-rockchip-samsung-hdptx.c:569:21: error: variable ‘rk_hdptx_phy_regmap_config’ has initializer but incomplete type
569 | static const struct regmap_config rk_hdptx_phy_regmap_config = {
| ^~~~~~~~~~~~~
../drivers/phy/rockchip/phy-rockchip-samsung-hdptx.c:570:10: error: ‘const struct regmap_config’ has no member named ‘reg_bits’
570 | .reg_bits = 32,
| ^~~~~~~~
Note that selecting REGMAP alone is not enough, because of the following
liker error:
phy-rockchip-samsung-hdptx.c:(.text+0x10c): undefined reference to `__devm_regmap_init_mmio_clk'
Instead of the obvious fix to enable REGMAP_MMIO, select MFD_SYSCON,
which implicitly enables REGMAP_MMIO as well. The rationale is that the
driver has been already relying on the syscon functionality.
Moreover, without MFD_SYSCON enabled, the test coverage is reduced,
since the linker might not detect any potential undefined references
following syscon_regmap_lookup_by_phandle() invocation in
rk_hdptx_phy_probe() body. That is because the function would
unconditionally return -ENOTSUP, hence the compiler is free to optimize
out any unreachable code.
Finally ensure PHY_ROCKCHIP_SAMSUNG_HDPTX depends on HAS_IOMEM, as
required by MFD_SYSCON.

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.

This adds a new USBDP combo PHY with Samsung IP block driver.
The driver get lane mux and mapping info in 2 ways, supporting
DisplayPort alternate mode or parsing from DT. When parsing from DT,
the property "rockchip,dp-lane-mux" provide the DP mux and mapping
info. This is needed when the PHY is not used with TypeC Alt-Mode.
For example if the USB3 interface of the PHY is connected to a USB
Type A connector and the DP interface is connected to a DisplayPort
connector.
When do DP link training, need to set lane number, link rate, swing,
and pre-emphasis via PHY configure interface.

Add driver for the HDMI/eDP TX Combo PHY found on Rockchip RK3588 SoC.
The PHY is based on a Samsung IP block and supports HDMI 2.1 TMDS, FRL
and eDP links. The maximum data rate is 12Gbps (FRL), while the minimum
is 250Mbps (TMDS).
Only the TMDS link is currently supported.

RK3568 supports PCIe v3 using not Combphy like PCIe v2 on rk3566.
It use a dedicated PCIe-phy. Add support for this.
Initial support by Shawn Lin, modifications by Peter Geis and Frank
Wunderlich.
Add data-lanes property for splitting pcie-lanes across controllers.
The data-lanes is an array where x=0 means lane is disabled and x > 0
means controller x is assigned to phy lane.

During review it came to light that exposing the pll clock outside is
not the right approach and struct phy_configure_opts_mipi_dphy exists
just for that reason to transfer parameters to the phy.
So drop the exposed clock and rely on the phy configure options
to bring in the correct rate. That way we can also just drop the
open coded timing struct and default values function.
