of/gpio: Implement of_gpio_count()

2008-12-21T03:21:14Z

This function is used to count how many GPIOs are specified for a device node. Signed-off-by: Anton Vorontsov Signed-off-by: Paul Mackerras

of/gpio: Implement of_get_gpio_flags()

2008-12-03T10:04:05Z

This adds a new function, of_get_gpio_flags, which is like of_get_gpio(), but accepts a new "flags" argument. This new function will be used by the drivers that need to retrieve additional GPIO information, such as active-low flag. Also, this changes the default ("simple") .xlate routine to warn about bogus (< 2) #gpio-cells usage: the second cell should always be present for GPIO flags.

of_gpio: Should use new header

2008-07-22T00:39:30Z

Since commit 7560fa60fcdcdb0da662f6a9fad9064b554ef46c (gpio: and "no GPIO support here" stubs) drivers can use GPIOs if they're available, but don't require them. This patch actually enables this feature. Signed-off-by: Wolfgang Grandegger Signed-off-by: Anton Vorontsov Signed-off-by: Benjamin Herrenschmidt

[POWERPC] OF helpers for the GPIO API

2008-04-16T21:46:11Z

This implements various helpers to support OF bindings for the GPIO LIB API. Previously this was PowerPC specific, but it seems this code isn't arch-dependent anyhow, so let's place it into of/. SPARC will not see this addition yet, real hardware seem to not use GPIOs at all. But this might change: http://www.leox.org/docs/faq_MLleon.html "16-bit I/O port" sounds promising. :-) Signed-off-by: Anton Vorontsov Acked-by: Grant Likely Signed-off-by: Paul Mackerras
