188a447b20 dt-bindings: phy: mediatek,tphy: allow simple nodename pattern
The pattern for the nodename only allows t-phy@... , however, for the case
when the t-phy has no `reg` and only `ranges` (basically when the t-phy
is just a parent node), dtc will throw this warning:

Warning (unit_address_vs_reg): /t-phy@1a243000: node has a unit name, but no reg or ranges property

For a node like this:

	sata_phy: t-phy@1a243000 {
		ranges;

		sata_port: sata-phy@1a243000 {
			reg = <0 0x1a243000 0 0x0100>;
		};
	};

it is normal that the parent node 't-phy' would be without any address, as in:

	sata_phy: t-phy {
		ranges;

		sata_port: sata-phy@1a243000 {
			reg = <0 0x1a243000 0 0x0100>;
		};
	};

because being just a holder it does not have its own reg.

However the binding does not allow such a name for the t-phy, so with this
patch, making the `@[0-9a-f]+` part optional, such node is possible.

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.

d1ea4239a1 phy/rockchip: inno-hdmi: add more supported pre-pll rates
This adds a bunch of new pixel clock- and tmds rates to the pre-pll
table which are required to get more VESA and some DMT rates working.

It has been completely re-calculated to match the min- and max-vco of
(750 MHz - 3.2 GHz) requirements. If more than one configuration would
have been possible the lowest fbdiv and refdiv (and therefore lowest
vco rate) has been preferred.

It's important to note, that RK3228 version of the phy does not support
fractional dividers. To support the most possible rates for this version
also in both 8-bit and 10-bit variant, some rates are not exact. The
maximum deviation of the pixel clock is 0.26, which perfectly fits into
VESA DMT recommendation of 0.5%.

I tested all possible rates on several screens from different
manufacturers with both RK3228 and RK3328. Both pre- and post-PLL
locking are slighlty faster now.

f79b812baf phy/rockchip: inno-hdmi: force set_rate on power_on
Regular 8-bit and Deep Color video formats mainly differ in TMDS rate and
not in pixel clock rate.
When the hdmiphy clock is configured with the same pixel clock rate using
clk_set_rate() the clock framework do not signal the hdmi phy driver
to set_rate when switching between 8-bit and Deep Color.
This result in pre/post pll not being re-configured when switching between
regular 8-bit and Deep Color video formats.

Fix this by calling set_rate in power_on to force pre pll re-configuration.

inno_write is used to configure 0xaa reg, that also hold the
POST_PLL_POWER_DOWN bit.
When POST_PLL_REFCLK_SEL_TMDS is configured the power down bit is not
taken into consideration.

Fix this by keeping the power down bit until configuration is complete.
Also reorder the reg write order for consistency.

inno_hdmi_phy_rk3328_clk_recalc_rate() is returning a rate not found
in the pre pll config table when the fractal divider is used.
This can prevent proper power_on because a tmdsclock for the new rate
is not found in the pre pll config table.

Fix this by saving and returning a rounded pixel rate that exist
in the pre pll config table.

Enabling clock for all the lanes consumes power even PHY is active or
inactive. To resolve this, enable/disable clocks in phy_init/phy_exit.

By default clock is disabled for all the lanes. Whenever phy_init called
from USB, SATA, or display driver, etc. It enabled the required clock
for requested lane. On phy_exit cycle, it disabled clock for the active
PHYs.

During the suspend/resume cycle, each USB/ SATA/ display driver called
phy_exit/phy_init individually. It disabled clock on exit, and enabled
on initialization for the active PHYs.
