USB2517 got three additionl downstream ports, which can
as well be mapped to another logical ports. USB251xb driver
currently doesn't fully support such setting configuration
from dts file. This patch doesn't change this, but adds
usb2517 spcific ports default liner mapping.

The driver used to be developed with legacy GPIO API support. It's
better to use descriptor-based interface for several reasons. First
of all the legacy API doesn't support the ACTIVE_LOW/HIGH flag of dts
nodes, which is essential since different hardware may have different
GPIOs connectivity inclu
USB2517 supports two LED modes: USB mode and speed (default) indication
mode. The last one can be switched on by corresponding dts property.
Since USB251xb hubs doesn't support LEDs settings, we need to ignore
this setting.

The methods like of_property_read_u32 utilizing the specified
pointer permit only the pointer to a preallocated u32 storage as the
third argument. As a result the driver crashes on NULL pointer
dereference in case if "oc-delay-us" or "power-on-time-ms" declared
in dts file.

This parameters may be varied in accordance with hardware specifics.
So lets add the corresponding settings to the usb251xb driver dts
specification.

Battery charging settings are supported by USB251xb hubs only.
USB2517i isn't one of them. So we need to reflect it within the
device-specific data structure. The driver doesn't support dts
property changing this setting, but instead defaults it with zero.
So the flag isn't used anywhere in the dri
USB electrical signaling drive strength boost bit is also supported
by USB2517 hub. Since it got three addition ports, the designers
needed to add one more register for initialization. It turned out
to be formerly reserved 0xF7. As before we just initialize it with
default zeros.

There are USB2517 and USB2517i hubs, which have almost the same
registers space as already supported USB251xBi series. The difference
it in DIDs and in a few functions. This patch adds the USB2517/i data
structures to the driver, so it would have different setting depending
on the device discovered
Since hub usb2517 is going to be supported by the usb251xb driver,
the bindings need to be properly updated. Particularly:
- add "microchip,usb2517" and "microchip,usb2517i" compatible strings.
- add "boolean" description to all the properties, which really accept
a boolean value including a new on
Primarily it was intended to just add USB2517 hub support to the driver.
But after tests a bug and inconistency were discovered. So it was decided
to make the following changes:
Changelog v1:
- Add USB2517/i hub specifics support to the driver
- Fix property_u32 NULL-pointer dereference
- Add new
USB251xb as well as USB2517 datasheet states, that all these
hubs differ by number of ports declared as the last digit in the
model name. So USB2512 got two ports, USB2513 - three, and so on.
Such setting must be reflected in the device specific data
structure and corresponding dts property should

Dear all,
I got the reviews from all maintainers related to this patch.
So, I make the immutable branch on extcon.git and then send
the pull request in order to prevent the possible merge conflict.
Best Regards,
