Initially I found this driver has set priv_auto_alloc_size but it actually never use dev->priv. The U_BOOT_DEVICE(lpc32xx_gpios) does not provide the platdata and all fields in struct lpc32xx_gpio_platdata are set in probe. It looks like the struct lpc32xx_gpio_platdata actually should be a priv data. Thus this patch renames lpc32xx_gpio_platdata to lpc32xx_gpio_priv and converts all dev_get_platdata() to dev_get_priv().
Signed-off-by: Axel Lin axel.lin@ingics.com --- Hi Albert, I don't have this h/w for testing, so only compile test. I'd appreciate if you can review and test this patch.
