[U-Boot] [PATCH v2 0/5] ARM: AT91: add AT91 PIO4 pinctrl driver

[Wenyou Yang]

AT91 PIO4 controller is a combined gpio-controller, pin-mux and
pin-config module. This patch is to add the pinctrl driver with
driver model and device tree support.

Changes in v2:
 - remove meaningless comment.
 - add else path for argument of pinconf.
 - add inline attribute for atmel_pio4_bank_base().
 - add handle if the pinmux entries is greater maximum value.
 - add detailed example to show how to configure pinctrl for device.
 - remove interrupt and gpio property description.
 - add reviewed-by tag.
 - integrate the gpio rework patch into this patch series.
 - add the new patch to move the PIO4 definitions to head file
   and rephrase them.
 - add the new patch to add #ifndef before CONFIG_ATMEL_PIO4
   in configs/sama5d2_xplained.h
