AT91 PIO4 controller is a combined gpio-controller, pin-mux and pin-config module.
This patch is to add the pinctrl driver, and rework the atmel-pio4 gpio driver to support driver model and device tree.
Changes in v7:
- Change clk_client.h -> clk.h to adapt to clk API conversion.
- Drop [PATCH]: configs: sama5d2_xplained: Add #ifndef before CONFIG_ATMEL_PIO4.
Changes in v6:
- Add Reviewed-by tag.
- Fixed the return value, -EINVAL -> ret.
Changes in v5:
- Update the clk API based on [PATCH] clk: convert API to match reset/mailbox fstyle (http://patchwork.ozlabs.org/patch/625342/).
- Use clrbits_le32() to replace readl()/writel().
- Fixed the return value, -ENODEV->-EINVAL.
- Remove check on dev_get_parent() return.
- Fixed the return value, -ENODEV->-EINVAL.
- Remove check on dev_get_parent() return.
Changes in v4:
- Remove the redundant log print.
Changes in v3:
- Add bind callback to support the pinctl device regarding as a child of atmel_pio4 device.
- Add clock support.
- Rework due to the pinctrl device is regarded as atmel_pio4 device's child.
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.
