* mfd: check for platform_get_irq() return value in sm501Roel Kluin2008-10-221-11/+11
| | | | | | | | sm501_devdata->irq is unsigned, while platform_get_irq() returns a signed int. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
* mfd: use pci_ioremap_bar() in sm501Arjan van de Ven2008-10-221-2/+1
| | | | | | | | | | Use the newly introduced pci_ioremap_bar() function in drivers/mfd. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks.

* mfd: twl4030-gpio driverDavid Brownell2008-10-223-0/+529
| | | | | | | | | | | | | | This adds basic support for the GPIOs in the twl4030 power management chip. That includes two open drain LED drivers, and the use of GPIO-0 (and GPIO-1) as MMC/SD card detect switches which can control whether the VMMC1 (and VMMC2) regulators are active. This version of the code has a debounce call that will probably be replaced before long, when a more generic interface exists.

* mfd: rtc-twl4030 driverDavid Brownell2008-10-223-0/+575
| | | | | | | | | | | | | | | | This adds a driver for the RTC inside the TWL4030 multi-function device. It's a fairly basic RTC, with a wake-capable alarm. Note that many of the pre-release Overo boards now in circulation can't effectively use this RTC, because of a wiring error that puts its TWL chip into "secure" mode. (As in "secure yourself against tampering".) This isn't an issue on other OMAP3 boards now supported in mainline, such as Beagle and Labrador.

* mfd: twl4030 IRQ handling updateDavid Brownell2008-10-223-405/+761
| | | | | | | | | | | | | | | | | | | | | - Move it into a separate file; clean and streamline it - Restructure the init code for reuse during secondary dispatch - Support both levels (primary, secondary) of IRQ dispatch - Use a workqueue for irq mask/unmask and trigger configuration Code for two subchips currently share that secondary handler code. One is the power subchip; its IRQs are now handled by this core, courtesy of this patch. The other is the GPIO module, which will be supported through a later patch. There are also minor changes to the header file, mostly related to GPIO support; nothing yet in mainline cares about those. A few references to OMAP-specific symbols are disabled; when they can all be removed, the TWL4030 support ceases being OMAP-specific.

* Export tiny shmem_file_setup for DRM-GEMHugh Dickins2008-10-201-1/+1
| | | | | | | | | | | | | We're trying to keep the !CONFIG_SHMEM tiny-shmem.c (using ramfs without swap) in synch with CONFIG_SHMEM shmem.c (and mpm is preparing patches to combine them). I was glad to see EXPORT_SYMBOL_GPL(shmem_file_setup) go into shmem.c, but why not support DRM-GEM when !CONFIG_SHMEM too? But caution says still depend on MMU, since !CONFIG_MMU is.. different.

Make the special case be a nice inlien function of its own, clean up the code, and make the warning go away.

The resource flags in this case are PCI_BASE_ADDRESS_MEM_TYPE_64 | PCI_BASE_ADDRESS_MEM_PREFETCH.

A single pci_slot may be associated with multiple pci_dev's, e.g. any multi-function PCI device. - when a pci_slot is released, look for all the pci_dev's it was associated with, and set their pci_slot pointers to NULL - when a pci_dev is created, look for slots to associate with.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are using 28bit pci (bus/dev/fn + 12 bits) as irq number, so the cache for irq number should be 32 bit too.

| * | | PCI PM: Introduce function pci_wake_from_d3Rafael J. Wysocki2008-10-201-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many device drivers use the following sequence of statements to enable the device to wake up the system while being in the D3_hot or D3_cold low power state: pci_enable_wake(pdev, PCI_D3hot, 1); pci_enable_wake(pdev, PCI_D3cold, 1); However, the second call is not necessary if the first one succeeds (the ordering of the statements above doesn't matter here) and it may even be harmful, because we are not supposed to enable PME# after the wake-up power has been enabled for the device. To allow drivers to overcome this problem, introduce function pci_wake_from_d3() that will enable the device to wake up the system from any of D3_hot and D3_cold as long as the wake-up from at least one of them is supported.

As this is a size-reduction option, it depends on CONFIG_EMBEDDED. It allows to save almost 12 kilobytes of kernel code: text data bss dec hex filename 1287806 123596 212992 1624394 18c94a vmlinux.old 1275854 123596 212992 1612442 189a9a vmlinux -11952 0 0 -11952 -2EB0 +/- This patch has originally been written by Zwane Mwaikambo <zwane@arm.linux.org.uk> and is part of the Linux Tiny project.
