Subject: [PATCH RFC 00/11 v4] gpio: Add block GPIO
Date: Tue, 16 Oct 2012 01:31:16 +0200 [thread overview]
Message-ID: <1350343887-7344-1-git-send-email-stigge@antcom.de> (raw)
This set of patches adds:
* Block GPIO API to gpiolib
* Sysfs support for GPIO API, to provide userland access
* Devicetree support to instantiate GPIO blocks via DT
* Example implementations in several gpio drivers since they need
special accessor functions for block wise GPIO access
Signed-off-by: Roland Stigge <stigge@antcom.de>

Changes since v3:
* Added driver support for pca953x, em, pl061, max732x, pcf857x
* Coding style improvements
* Fixed krealloc memory leak in error case
* sysfs: values in hex
* Register blocks in a list
* Narrowing lock scope
* Use S_IWUSR and S_IRUGO instead of direct octal values
* Use for_each_set_bit()
* Change from unsigned to unsigned long for masks and values
Changes since v2:
* Added sysfs support
* Added devicetree support
* Added support for lpc32xx, generic
* Added functions for GPIO block registration
* Added more error checking
* Bit remapping bugfix
Changes since v1:
* API change to 32/64 bit word, bit masks
Thanks to Ryan Mallon, Linus Walleij, Stijn Devriendt, Jean-Christophe
