linux-toradex.git/drivers/gpio/gpio-vx855.c, branch v4.9.123 Linux kernel for Apalis and Colibri modules gpio: vx855: use the new open drain callback 2016-04-14T12:03:28+00:00 Linus Walleij linus.walleij@linaro.org 2016-04-10T10:26:08+00:00 640b9135c888f02afd058c213303ffbd10d3908d The vx855 driver clearly states it has three groups of lines: GPI, GPO and GPIO. The GPO are assumedly push-pull. The GPIO are implicit open drain, but if the GPIO subsystem ask for them to be explicitly open drain (i.e. set the flag on a machine table that we want open drain) it will currently misbehave: it will switch the GPIOs to input mode (emulate open drain). Instead: indicate in the .set_single_ended() callback that we support open drain and open drain only. Cc: Daniel Drake <drake@endlessm.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

gpio/pinctrl: make gpio_chip members typed boolean 2013-12-04T13:42:46+00:00 Linus Walleij linus.walleij@linaro.org 2013-12-04T13:42:46+00:00 9fb1f39eb2d6707d265087ee186376e24995f55a This switches the two members of struct gpio_chip that were defined as unsigned foo:1 to bool, because that is indeed what they are. Switch all users in the gpio and pinctrl subsystems to assign these values with true/false instead of 0/1. The users outside these subsystems will survive since true/false is 1/0, atleast we set some kind of more strict typing example. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
