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.
