cs5535: drop the Geode-specific MFGPT/GPIO code

2009-12-15T16:53:28Z

With generic modular drivers handling all of this stuff, the geode-specific code can go away. The cs5535-gpio, cs5535-mfgpt, and cs5535-clockevt drivers now handle this.

x86, geode: add a VSA2 ID for General Software

2008-06-19T12:19:03Z

General Software writes their own VSA2 module for their version of the Geode BIOS, which returns a different ID then the standard VSA2. This was causing the framebuffer driver to break for most GSW boards. Signed-off-by: Jordan Crouse Cc: tglx@linutronix.de Cc: linux-geode@lists.infradead.org Signed-off-by: Ingo Molnar

x86: GEODE: cache results from geode_has_vsa2() and uninline

2008-05-08T13:43:50Z

This moves geode_has_vsa2 into a .c file, caches the result we get from the VSA virtual registers, and causes the function to no longer be inline.

x86: GEODE: MFGPT: Use "just-in-time" detection for the MFGPT timers

2008-02-09T22:24:08Z

There isn't much value to always detecting the MFGPT timers on Geode platforms; detection is only needed when something wants to use the timers. Move the detection code so that it gets called the first time a timer is allocated.

x86: GEODE: update GPIO API to support setting multiple GPIOs at once

2008-01-30T12:33:35Z

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.

x86: Geode Multi-Function General Purpose Timers support

2007-10-12T21:04:06Z

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.
