Add helper function to update register bits instead of overwriting the
entire control register when updating the flow-control settings.
This specifically avoids having the tranceiver suspend mode (bit 0)
depend on the flow control setting.
The tranceiver is currently configured at probe to be dis
Older pl2303 devices do not support automatic xon/xoff flow control, so
add add a flag to prevent trying to enable it for legacy device types.
Refactor the IXON test into a helper function to improve readability.
Fixes: 7041d9c3f01b ("USB: serial: pl2303: add support for tx xon/xoff flow

These patches fix two issues with the current flow-control
implementation.
Tested using an HXD device.

Hi Felipe,
Do you know why? In that case, I can't change property, eg changing qmult at NCM

Hi,
Theses patches tries to clean a bit dwc2's phy initialization and
fix an issue in gadget mode where the utmi phy width is set
regardless of utmi being used or not.
I believe that when using ulpi a phy width of 8 bits must be used,
but this wasn't the case as the variable phyif was set by defa
As the phy initialization is almost the same in host and gadget
mode. This only move the phy initialization functions into core.c
for now, the goal is to share theses functions between the two modes.

Most of the phy initialization is shared between host and gadget,
this adds the turnaround configuration only used by gadgets to
the global phy init.

The phy utmi width information is already set in hsotg params,
phyif is only used in few places and I don't see any reason to
not use hsotg's params.
Moreover the utmi width was being forced to 16 bits by platform
initialization which doesn't take in account HW configuration.

The function dwc2_hsotg_init is only called once just before calling
dwc2_hsotg_core_init_disconnected which does the same initialization:
setting the usbcfg register with turnaround time, timeout calibration
and phy width.
