MIPS: TXx9: Be sure to clamp return value 2016-01-24T01:22:14+00:00 Linus Walleij linus.walleij@linaro.org 2015-12-22T14:41:01+00:00 6ea6b7faf0fbc7f2bb55277befe478c0a66659fc As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern.

[MIPS] txx9: Make gpio_txx9 entirely spinlock-safe 2008-07-15T17:44:34+00:00 Atsushi Nemoto anemo@mba.ocn.ne.jp 2008-07-09T16:02:08+00:00 14476007c90005c8992b786c15a59cca31f53268 TXx9 GPIO set/get routines are spinlock-safe. This patch make gpio_direction_{input,output} routines also spinlock-safe so that they can be used during early board setup.
