Wei Yongjun 2207a4e1ca pinctrl: vt8500: wmt: remove redundant dev_err call in wmt_pinctrl_probe()
There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.

Axel Lin 97fc463769 pinctrl: Don't override the error code in probe error handling
Otherwise, we return 0 in probe error paths when gpiochip_remove() returns 0.
Also show error message if gpiochip_remove() fails.

Tony Prisk 1c7ad8f001 pinctrl: vt8500: Fix incorrect data in WM8750 pinctrl table
WMT_PIN_WAKEUP1 should be declared as WMT_PIN(0, 17) rather than
WMT_PIN(0, 16). This currently generates a runtime warning because
WMT_PIN_WAKEUP0 is already defined as WMT_PIN(0, 16).

Tony Prisk 170c6152ae pinctrl: gpio: vt8500: Add pincontrol driver for arch-vt8500
This patch adds support for the GPIO/pinmux controller found on the VIA
VT8500 and Wondermedia WM8xxx-series SoCs.

Each pin within the controller is capable of operating as a GPIO or as
an alternate function. The pins are numbered according to their control
bank/bit so that if new pins are added, the existing numbering is maintained.

All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and
WM8850.
