The initial otg state for the phy defaults to device mode. The actual
state isn't detected until an ID IRQ fires. Fix this by syncing the ID
state during initialization.

Some SoCs have a bvalid falling interrupt, in addition to bvalid rising.
This interrupt can detect OTG cable plugout immediately, so it can avoid
the delay until the next scheduled work.

The "bvalid" and "id" interrupts can trigger on either the rising edge
or the falling edge, so each interrupt has two enable bits and two
status bits. This change allows using a single property for both bits,
checking whether either bit is set.

The bvalid interrupt handler already checks bvalid status. The muxed IRQ

This commit fixes two issues with the muxed interrupt handler. First,
the OTG port has the "bvalid" interrupt enabled, not "linestate". Since
only the linestate interrupt was handled, and not the bvalid interrupt,
plugging in a cable to the OTG port caused an interrupt storm.
Second, the return values from the individual port IRQ handlers need to
be OR-ed together. Otherwise, the lack of an interrupt from the last
port would cause the handler to erroneously return IRQ_NONE.

The D-PHY specification (v1.2) explicitly mentions that the T-CLK-PRE
parameter's unit is Unit Interval(UI) and the minimum value is 8. Also,
kernel doc of the 'clk_pre' member of struct phy_configure_opts_mipi_dphy
mentions that it should be in UI. However, the dphy core driver wrongly
sets 'clk_pre' to 8000, which seems to hint that it's in picoseconds.
So, let's fix the dphy core driver to correctly reflect the T-CLK-PRE
parameter's minimum value according to the D-PHY specification.
I'm assuming that all impacted custom drivers shall program values in
TxByteClkHS cycles into hardware for the T-CLK-PRE parameter. The D-PHY
specification mentions that the frequency of TxByteClkHS is exactly 1/8
the High-Speed(HS) bit rate(each HS bit consumes one UI). So, relevant
custom driver code is changed to program those values as
DIV_ROUND_UP(cfg->clk_pre, BITS_PER_BYTE), then.
Note that I've only tested the patch with RM67191 DSI panel on i.MX8mq EVK.
Help is needed to test with other i.MX8mq, Meson and Rockchip platforms,
as I don't have the hardwares.

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.

Commit 287422a95f ("drm/rockchip: Round up _before_ giving to the clock framework")
changed what rate clk_round_rate() is called with, an additional 999 Hz
added to the requsted mode clock. This has caused a regression on RK3328
and presumably also on RK3228 because the inno-hdmi-phy clock requires an
exact match of the requested rate in the pre pll config table.
When an exact match is not found the parent clock rate (24MHz) is returned
to the clk_round_rate() caller. This cause wrong pixel clock to be used and
result in no-signal when configuring a mode on RK3328.
Fix this by rounding the rate down to closest 1000 Hz in round_rate func,
this allows an exact match to be found in pre pll config table.
