[PATCH 0/3] ARM: dts: vf610: USB/GPIO fixes

[Stefan Agner]

Hi Shawn,

This patchset collects some vf610 device tree fixes. The first patch
was part of the "vf610: Add GPIO support" patchset. GPIO support is
merged by know, so I rebased that on top of your for-next branch.

The second patch is a USB fix I uncovered while testing the 3rd patch,
which adds regulators, mainly for proper USB VBUS support, as we have
them on our carrier boards.

[PATCH 1/3] ARM: dts: vf610: use new GPIO support

[Stefan Agner]

Use GPIO support by adding SD card detection configuration and
GPIO pinmux for Colibri's standard GPIO pins. Attach the GPIO
pins to the iomuxc node to get the GPIO pin settings applied.

[PATCH 2/3] ARM: dts: vf610: enable USB misc/phy nodes where necessary

[Stefan Agner]

Since restructuring of the device tree files, the USB misc/phy
nodes are disabled by default. Hence we need to enable those
explicitly when USB is used.

The numbering generally starts from 0 instead of 1.

We used to know the GPIO usage by looking for the phandle reference to
the node.  But it doesn't work for VF610 case now.

I guess this is for usbh_vbus_reg usage?  It would be nice to have a
comment telling the usage of the GPIO.

Yeah its true, its assign is not required for Vybird. However, we could
assign them anyway, it would even enforce correct pin setup from
Startup... This would then make a comment superfluous. What do you
think?

This is not yet used. It is more or less the OTG-ID pin, but on 3.3V
level. We use that on the Colibri standard to switch between Host/Device
mode, however a driver which uses that GPIO is still outstanding. I can
also leave that away for now, if you prefer....

I agree with the approach of assigning the phandle anyway.
