pinctrl: Flag strict is a field in struct pinmux_ops

2016-10-07T13:23:41+00:00

commit 7440926ed9623dceca3310c5f437d06c859dc02b upstream. Documentation incorrectly refers to struct pinctrl_desc, where no such flag is available. Replace the name of the struct.

pinctrl: move strict option to pinmux_ops

2015-05-06T12:45:19+00:00

While the pinmux_ops are ideally just a vtable for pin mux calls, the "strict" setting belongs so intuitively with the pin multiplexing that we should move it here anyway. Putting it in the top pinctrl_desc makes no sense. Cc: Sonic Zhang Signed-off-by: Linus Walleij

pinctrl: allow exlusive GPIO/mux pin allocation

2015-05-06T12:45:19+00:00

Disallow simultaneous use of the the GPIO and peripheral mux functions by setting a flag "strict" in struct pinctrl_desc. The blackfin pinmux and gpio controller doesn't allow user to set up a pin for both GPIO and peripheral function. So, add flag strict in struct pinctrl_desc to check both gpio_owner and mux_owner before approving the pin request. v2-changes: - if strict flag is set, check gpio_owner and mux_onwer in if and else clause v3-changes: - add kerneldoc for this struct - augment Documentation/pinctrl.txt Signed-off-by: Sonic Zhang Signed-off-by: Linus Walleij

pinctrl: remove doc mention of the enable/disable API

pinctrl: remove enable/disable callbacks from documentation

2015-03-18T01:02:17+00:00

Commit 03e9f0cac5d (pinctrl: clean up after enable refactoring) updated the documentation to remove mention of disable(), and rename enable() to set_mux(). One in-text mention was forgotten. Fix this. Fixes: 03e9f0cac5d ('pinctrl: clean up after enable refactoring') Signed-off-by: Baruch Siach Signed-off-by: Linus Walleij

pinctrl: remove maxpin from documentation

2015-03-09T17:11:00+00:00

struct pinctrl_desc does not contain the maxpin member since commit 0d2006bbf0 (pinctrl: remove unnecessary max pin number). Fixes: 0d2006bbf0 ('pinctrl: remove unnecessary max pin number') Signed-off-by: Baruch Siach Signed-off-by: Linus Walleij

pinctrl: clean up after enable refactoring

2014-09-04T08:05:07+00:00

commit 2243a87d90b42eb38bc281957df3e57c712b5e56 "pinctrl: avoid duplicated calling enable_pinmux_setting for a pin" removed the .disable callback from the struct pinmux_ops, making the .enable() callback the only remaining callback. However .enable() is a bad name as it seems to imply that a muxing can also be disabled. Rename the callback to .set_mux() and also take this opportunity to clean out any remaining mentions of .disable() from the documentation.

pinctrl: Fix some typos and grammar issues in the documentation

2014-01-15T12:59:50+00:00

I had been trying to learn a bit more about the pinctrl subsystem, and I realized several typos and grammar issues while going through the documentation. I have probably not caught all the possible issues, but this change is addressing several places for improvement. Signed-off-by: Laszlo Papp Signed-off-by: Linus Walleij
