generic gpio support interfaces for pl2303 USB Serial devices
in pl2303_type_data and pl2303_serial_private, then use them
to add GPIOs support for one type of them, PL2303HXA.

Since the dwc2 hcd driver is currently not looking for a clock node during
init, we should not completely fail if there isn't a clock provided.
Add a check for a valid clock before calling clock functions.

This series fixes a possible lock in the uvc-gadget.
It also adds ENUM_FMT to the v4l2 ioctl list. This
way it will be possible to use gstreamer with it.
At last we increase isoc requests in flight.

This patch adds ENUM_FMT as possible ioctl to the uvc v4l2 device.
That makes userspace applications with a generic IOCTL calling

If the pending buffers in the queue could not be pushed to the udc

According to the datasheet, PHYPARAM1_PCS_TXDEEMPH_3P5DB is a
correct name. Thus, a _3P5DB suffix for the PHYPARAM1_PCS_TXDEEMPH
register bit field definition is added.
In addition, PHYPARAM1_PCS_TXDEEMPH_3P5DB(_x) is added in order to
keep the same style, as other register bit field definitions a
According to the datasheet, PHYPARAM1_PCS_TXDEEMPH is set as
6 bits [5:0]. Thus, the bit mask should be set as 0x3f, instead
of 0x1f.
