    Subject[PATCH v2 1/2] pinctrl: show pin name when request pins
    Date
    From: Dong Aisheng <dong.aisheng@linaro.org>

    Pin name is more useful to users.

    Signed-off-by: Dong Aisheng <dong.aisheng@linaro.org>

    No changes since v1.

    After change, when call pinctrl_get_*, the debug information becomes :
    pinctrl-imx 20e0000.iomuxc: request pin 305 (MX6Q_PAD_SD4_CMD) for 219c000.usdhc
    pinctrl-imx 20e0000.iomuxc: request pin 306 (MX6Q_PAD_SD4_CLK) for 219c000.usdhc
