2008-07-25gpiolib: allow user-selectionMichael Buesch
This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.

2008-07-24add HAVE_CLK to Kconfig, for driver dependenciesDavid Brownell
Flag platforms as HAVE_CLK (or not) in Kconfig, based on whether they support <linux/clk.h> calls, so that otherwise portable drivers which need those calls can list that dependency. Something like this is a prerequisite for merging the musb_hdrc driver, currently used on platforms including Davinci, OMAP2430, OMAP3xx ... and the discrete TUSB6010 chip, which doesn't have a natural platform dependency.

2008-02-05gpiolib support for the PXA architecturePhilipp Zabel
This adds gpiolib support for the PXA architecture: - move all GPIO API functions from generic.c into gpio.c - convert the gpio_get/set_value macros into inline functions This makes it easier to hook up GPIOs provided by external chips like ASICs and CPLDs.

2008-02-05gpiolib: add drivers/gpio directoryDavid Brownell
Add an empty drivers/gpio directory for gpiolib infrastructure and GPIO expanders. It will be populated by later patches. This won't be the only place to hold such gpio_chip code. Many external chips add a few GPIOs as secondary functionality (such as MFD drivers) and platform code frequently needs to closely integrate GPIO and IRQ support. This is placed *early* in the build/link sequence since it's common for other drivers to depend on GPIOs to do their work, so they must be initialized early in the device_initcall() sequence.
