Before reboot if the DCDC is disabled,
the DCDC is still disabled after restart.
We have an method to workaround:
Use vsel pin to switch the voltage between value in FAN53555_VSEL0
and FAN53555_VSEL1. If VSEL pin is inactive, the voltage of DCDC
are controlled by FAN53555_VSEL0, when we pull vsel pin to active,
they would be controlled by FAN53555_VSEL1.
In this case, we can set FAN53555_VSEL1 to disable dcdc,
So we can make vsel pin to active to disable dcdc,
VSEL pin is inactive to enable DCDC.

When we use the MIPI screen, the driver will unprepare and disable
the phy_cfg, it will diable its parent pclk_vio:
dw_mipi_dsi_phy_init
--> clk_disable_unprepare
--> clk_disable
--> clk_core_disable(core->parent)
The pclk_vio supply power for pclk_vio_grf, hence, disable pclk_vio_grf will
cause other drivers failed to operate GRF.

Therefore, we can select dclk_vopx below the dclk_vopx_div directly.

Some EHCI controllers use usic phy (e.g rk3399/rk3288),
in order to enable these controllers, we need to set
some additional EHCI vendor-specific registers.
Support this feature in device tree when using the ehci

For the hardware bug of RK3288 OHCI, we use commit cfe6f1dd57
("usb: ehci: add rockchip relinquishing port quirk support") to fix
it previously. However, it have been ineffective after upstream commit
94c43b9897 ("USB: Check for dropped connection before switching to
full speed") was merged due to the condition of relinquishing port was
changed.
This patch adds an additional condition for the previous commit to ensure
no relinquish port quirk can take effect for RK3288 EHCI.

We observed the failure of initializing card after resume
accidentally. It's hard to reproduce but we did get report from
the suspend/resume test of our RK3399 mp test farm .Unfortunately,
we still fail to figure out what was going wrong at that time.
Also we can't achieve it by retrying the host->f_init without falling
back it. But this patch will solve the problem as we could add some log
there and see that we resume the mmc card successfully after falling
back the host->f_init. There is no obviousside effect found, so it seems
this patch will improve the stability.
