* [PATCH] USB: pxa27x OHCI - Separate platform code from main driverRichard Purdie2006-01-041-0/+18
| | | | | | | | | | | | | | | | To allow multiple platforms to use the PXA27x OHCI driver, the platform code needs to be moved into the board specific files in arch/arm/mach-pxa. This patch does this for mainstone and adds preliminary hooks to allow other boards to use the driver. This has been compile tested for mainstone and successfully run on Spitz (Sharp Zaurus SL-C3000) with the addition of an appropriate board support file.

* [ARM SMP] Use event instructions for spinlocksRussell King2005-12-011-2/+24
| | | | | | | | | | | | | ARMv6K CPUs have SEV (send event) and WFE (wait for event) instructions which allow the CPU clock to be suspended until another CPU issues a SEV, rather than spinning on the lock wasting power. Make use of these instructions. Note that WFE does not wait if an event has been sent since the last WFE cleared the event status, so although it may look racy, the instruction implementation ensures that these are dealt with.

| | | | | | | | | | | | | | | | | | | | | | | Patch from Liam Girdwood This patch allows users of the pxa SSP driver to register their own irq handlers instead of using the default SSP handler. It also cleans up the CKEN clock and irq detection as the values are now stored in a table. This patch replaces 2845/1 Changes:- o Added flags parameter to ssp_init() o Added SSP_NO_IRQ flag to disable registering of ssp irq handler (for drivers that want to register their own handler) o Cleaned up clock and irq detection, values are now stored in table. o Added build changes to allow other drivers (e.g audio) to select the ssp driver. o corgi_ssp.c changed to use new interface.

* [ARM] 3096/1: Add SharpSL Zaurus power and battery management core driverRichard Purdie2005-11-101-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | Patch from Richard Purdie This patch adds a power and battery management core driver which with the addition of the right device files, supports the c7x0 and cxx00 series of Sharp Zaurus handhelds. The driver is complex for several reasons. Battery charging is manually monitored and controlled. When suspended, the device needs to periodically partially resume, check the charging status and then re-suspend. It does without bothering the higher linux layers as a full resume and re-suspend is unnecessary. The code is carefully written to avoid interrupts or calling code outside the module under these circumstances. It also vets the various wake up sources and monitors the device's power situation. Hooks to limit the backlight intensity and to notify the battery monitoring code of backlight events are connected/added as the backlight is one of the biggest users of power on the device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Alessandro Zummo This patch adds support for the LinkSys NSLU2 running with both big and little-endian kernels. The LinkSys NSLU2 is a cost engineered ARM, XScale 420 based system similar to the the Intel IXDP425 evaluation board. It uses the IXP4XX ARCH. While this patch applies independently of other patches the resultant kernel requires further patches to successfully use onboard devices, including the onboard flash. Since these patches are independent of this one they will be submitted separately. A defconfig is not included here because not all of the required drivers are actually in the kernel. We intend to provide one as soon as the patches will be incorporated in mainstream.
