[RFT PATCH 0/6] pinctrl: meson: Fix gpio-ranged for GPIO Hog

[narmstrong@baylibre.com (Neil Armstrong)]

Whem trying to add a gpio hog to enable the USB Hub on the Odroid-C2, I
encountered a strange bug where when calling gpiochip_add_data() the gpiolib
code was trying to add the Hog but failed because the gpio ranges were missing.

In the meson-pinctrl driver, the gpio ranges are added manually /after/ the
call to gpiochip_add_data().
The arch/arm meson8 and meson8b patches has not been tested, this is why this
patchset is an RFT.

So this patchset uses the DT gpio-ranges attribute instead and solves the issue.

The final patch is the actual GPIO Hog for the Odroid-C2 board, which is an ugly
hack but is necessary to have USB Ports working on the board until the generic
power sequence framework is merged.
