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: MFGPT: make mfgpt_timer_setup available outside of mfgpt_32.c

2008-02-09T22:24:08Z

We need to be called from elsewhere, and this gets some #ifdefs out of the .c file. Signed-off-by: Andres Salomon Signed-off-by: Jordan Crouse Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

x86: GEODE: MFGPT: drop module owner usage from MFGPT API

2008-02-09T22:24:08Z

We had planned to use the 'owner' field for allowing re-allocation of MFGPTs; however, doing it by module owner name isn't flexible enough. So, drop this for now. If it turns out that we need timers in modules, we'll need to come up with a scheme that matches the write-once fields of the MFGPTx_SETUP register, and drops ponies from the sky.

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.

GEODE: use symbolic constant in cs5536 reboot fixup

2007-10-19T18:35:02Z

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 Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

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.
