This patch add some optional configuration for dt. freq-sel can be used
to decide the phy sample clk in order to match the real freq of emmc
controller. dr-sel can be configured to match the requirement of different
drive strength of phy IO. opdelay should be used to adjust the output
delay for clk IO and data IO, which is useful for sloving timing issue.

We must not to adjust the port order, cause the port id is mapping
to VOP type. Current driver just hardcode that VOP Lit is ID 0, and
VOP Big is ID 1.
ret = rockchip_drm_encoder_get_mux_id(dp->dev->of_node, encoder);
if (ret)
val = dp->data->lcdsel_lit | dp->data->lcdsel_mask;
else
val = dp->data->lcdsel_big | dp->data->lcdsel_mask;
Besides eDP could work well with VOP Lit, so we need to revert this
hack. Just revert commit 602f4f79c8.

The PLL function was updated to disallow 32KHz in
commit 501f72e9c5 ("ASoC: da7219: Remove support for 32KHz PLL mode"),
but set_dai_sysclk() was missed and still permits it. This patch resolves

There is a pull up resistor connected to eDP HPD pin on EVB1
hardware, and then eDP controller would always reported that
eDP panel is connected, even if no panel connected.
That would cause driver keep failed on eDP AUX communication,
and lots of annoying error messages would be printed out.
Beside actually the primary panel on EVB1 board is MIPI panel,
few people would have the eDP panel. So let's just disabled
the eDP device on EVB1 board.

Rockchip Socs contain quality of service (qos) blocks managing priority,
bandwidth, etc of the connection of each domain to the interconnect.
These blocks loose state when their domain gets disabled and therefore
need to be saved when disabling and restored when enabling a power-domain.
These qos blocks also are similar over all currently available Rockchip
SoCs.

When changing the clock-rate, currently a new parent is set first and a
divider adapted thereafter. This may result in the clock-rate overflowing
its target rate for a short time if the new parent has a higher rate than
the old parent.
While this often doesn't produce negative effects, it can affect components
in a voltage-scaling environment, like the GPU on the rk3399 socs, where
the voltage than simply is to low for the temporarily to high clock rate.
For general clock hirarchies this may need more extensive adaptions to
the common clock-framework, but at least for composite clocks having
both parent and rate settings it is easy to create a short-term solution to
make sure the clock-rate does not overflow the target.

In OS descriptors handling, if ctrl->bRequestType is USB_RECIP_DEVICE
and w_index != 0x4 or (w_value >> 8) is true, it will not reset
req->length, but use the default value(-EOPNOTSUPP), and queue an
OS desc request with an invalid req->length. It always happens
on the platforms which use os_desc(for example: rk3366,rk3399),
and cause kernel panic as follows(use dwc3 driver):
