Subject: gpio: lpc32xx: Use priv_data instead of platdata
X-Git-Tag: v2015.07~27^2~9
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=1f9e5e228c23831bb8e8896209bb67ebcfaf59a7;p=u-boot

gpio: lpc32xx: Use priv_data instead of platdata

The LPC32XX GPIO driver platdata currently contains GPIO state information,
which should go into priv_data. Thus rename lpc32xx_gpio_platdata to
lpc32xx_gpio_priv and convert to use dev_get_priv() instead.
