2008-01-30	x86: GEODE: update GPIO API to support setting multiple GPIOs at once	Andres Salomon
	The existing Geode GPIO API only allows for updating one GPIO at once. There are instances where users want to update multiple GPIOs at once. With the current API, they are given two choices; either ignore the GPIO API: outl(0xc000, gpio_base + GPIO_OUTPUT_VAL); outl(0xc000, gpio_base + GPIO_OUTPUT_ENABLE); Alternatively, call each GPIO update separately: geode_gpio_set(14, GPIO_OUTPUT_VAL); geode_gpio_set(15, GPIO_OUTPUT_VAL); geode_gpio_set(14, GPIO_OUTPUT_ENABLE); geode_gpio_set(15, GPIO_OUTPUT_ENABLE); Neither are desirable. This patch changes the GPIO API to allow for setting of multiple GPIOs at once; rather than being passed an integer, we pass a bitmask and provide a translation function. The above code would now look like this: geode_gpio_set(geode_gpio(14)\|geode_gpio(15), GPIO_OUTPUT_VAL); geode_gpio_set(geode_gpio(14)\|geode_gpio(15), GPIO_OUTPUT_ENABLE); Since there are no upstream users of the GPIO API yet (afaik), best to change this now. This also adds a bit of sanity checking; it is no longer possible to use a GPIO above 28. Note the semantics of geode_gpio_isset() have changed: geode_gpio_isset(geode_gpio(3)\|geode_gpio(4), ...) will only return true iff both GPIOs are set.

2007-10-19	GEODE: use symbolic constant in cs5536 reboot fixup	Andres Salomon
	Simple cosmetic update for the cs5536 reboot fixup; define the MSR that's used for rebooting in geode.h, and use the define. Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2007-10-12	x86: Geode Multi-Function General Purpose Timers support	Andres Salomon
	This adds support for Multi-Function General Purpose Timers. It detects the available timers during southbridge init, and provides an API for allocating and setting the timers. They're higher resolution than the standard PIT, so the MFGPTs come in handy for quite a few things. Note that we never clobber the timers that the BIOS might have opted to use; we just check for unused timers.
