| * gpio: add a userspace chardev ABI for GPIOsLinus Walleij2016-02-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new chardev that is to be used for userspace GPIO access is added in this patch. It is intended to gradually replace the horribly broken sysfs ABI. Using a chardev has many upsides: - All operations are per-gpiochip, which is the actual device underlying the GPIOs, making us tie in to the kernel device model properly. - Hotpluggable GPIO controllers can come and go, as this kind of problem has been know to userspace for character devices since ages, and if a gpiochip handle is held in userspace we know we will break something, whereas the sysfs is stateless. - The one-value-per-file rule of sysfs is really hard to maintain when you want to twist more than one knob at a time, for example have in-kernel APIs to switch several GPIO lines at the same time, and this will be possible to do with a single ioctl() from userspace, saving a lot of context switching. We also need to add a new bus type for GPIO. This is necessary for example for userspace coldplug, where sysfs is traversed to find the boot-time device nodes and create the character devices in /dev. This new chardev ABI is *non* *optional* and can be counted on to be present in the future, emphasizing the preference of this ABI. The ABI only implements one single ioctl() to get the name and number of GPIO lines of a chip. Even this is debatable: see it as a minimal example for review. This ABI shall be ruthlessly reviewed and etched in stone. The old /sys/class/gpio is still optional to compile in, but will be deprecated. Unique device IDs are created using IDR, which is overkill and insanely scalable, but also well tested.

* | gpio: Add GPIO support for the ACCES 104-DIO-48EWilliam Breathitt Gray2016-01-281-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ACCES 104-DIO-48E device provides 48 lines digital I/O via two Programmable Peripheral Interface (PPI) chips of type 82C55. Bit C3 at each 24-bit Group can be used as an external interrupt, triggered by a rising edge. This driver provides GPIO and IRQ support for these 48 channels of digital I/O. The base port address for the device may be configured via the dio_48e_base module parameter. The interrupt line number for the device may be configured via the dio_48e_irq module parameter.

BIOS can reassign one or more Root Ports to appear within a VMD domain instead of the primary domain. The immediate benefit is that additional PCIe domains allow more than 256 buses in a system by letting bus numbers be reused across different domains. VMD domains do not define ACPI _SEG, so to avoid domain clashing with host bridges defining this segment, VMD domains start at 0x10000, which is greater than the highest possible 16-bit ACPI defined _SEG. This driver enumerates and enables the domain using the root bus configuration interface provided by the PCI subsystem. The driver provides configuration space accessor functions (pci_ops), bus and memory resources, an MSI IRQ domain with irq_chip implementation, and DMA operations necessary to use devices through the VMD endpoint's interface. VMD routes I/O as follows: 1) Configuration Space: BAR 0 ("CFGBAR") of VMD provides the base address and size for configuration space register access to VMD-owned root ports. It works similarly to MMCONFIG for extended configuration space. Bus numbering is independent and does not conflict with the primary domain. 2) MMIO Space: BARs 2 and 4 ("MEMBAR1" and "MEMBAR2") of VMD provide the base address, size, and type for MMIO register access. These addresses are not translated by VMD hardware; they are simply reservations to be distributed to root ports' memory base/limit registers and subdivided among devices downstream. 3) DMA: To interact appropriately with an IOMMU, the source ID DMA read and write requests are translated to the bus-device-function of the VMD endpoint. Otherwise, DMA operates normally without VMD-specific address translation. 4) Interrupts: Part of VMD's BAR 4 is reserved for VMD's MSI-X Table and PBA. MSIs from VMD domain devices and ports are remapped to appear as if they were issued using one of VMD's MSI-X table entries. Each MSI and MSI-X address of VMD-owned devices and ports has a special format where the address refers to specific entries in the VMD's MSI-X table. As with DMA, the interrupt source ID is translated to VMD's bus-device-function. The driver provides its own MSI and MSI-X configuration functions specific to how MSI messages are used within the VMD domain, and provides an irq_chip for independent IRQ allocation to relay interrupts from VMD's interrupt handler to the appropriate device driver's handler. 5) Errors: PCIe error message are intercepted by the root ports normally (e.g., AER), except with VMD, system errors (i.e., firmware first) are disabled by default. AER and hotplug interrupts are translated in the same way as endpoint interrupts. 6) VMD does not support INTx interrupts or IO ports. Devices or drivers requiring these features should either not be placed below VMD-owned root ports, or VMD should be disabled by BIOS for such endpoints.

From the new material perspective the most significant are the driver core changes that should allow USB devices to stay suspended over system suspend/resume cycles if they have been runtime-suspended already beforehand. Apart from that, ACPICA is updated to upstream revision 20160108 (cosmetic mostly, but including one fixup on top of the previous ACPICA update) and there are some devfreq updates the didn't make it before (due to timing). A few recent regressions are fixed, most importantly in the cpuidle menu governor and in the ACPI backlight driver and some x86 platform drivers depending on it. Some more bugs are fixed and cleanups are made on top of that. Specifics: - Modify the driver core and the USB subsystem to allow USB devices to stay suspended over system suspend/resume cycles if they have been runtime-suspended already beforehand and fix some bugs on top of these changes (Tomeu Vizoso, Rafael Wysocki). - Update ACPICA to upstream revision 20160108, including updates of the ACPICA's copyright notices, a code fixup resulting from a regression fix that was necessary in the upstream code only (the regression fixed by it has never been present in Linux) and a compiler warning fix (Bob Moore, Lv Zheng). - Fix a recent regression in the cpuidle menu governor that broke it on practically all architectures other than x86 and make a couple of optimizations on top of that fix (Rafael Wysocki). - Clean up the selection of cpuidle governors depending on whether or not the kernel is configured for tickless systems (Jean Delvare). - Revert a recent commit that introduced a regression in the ACPI backlight driver, address the problem it attempted to fix in a different way and revert one more cosmetic change depending on the problematic commit (Hans de Goede). - Add two more ACPI backlight quirks (Hans de Goede). - Fix a few minor problems in the core devfreq code, clean it up a bit and update the MAINTAINERS information related to it (Chanwoo Choi, MyungJoo Ham). - Improve an error message in the ACPI fan driver (Andy Lutomirski). - Fix a recent build regression in the cpupower tool (Shreyas Prabhu)" * tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (32 commits) cpuidle: menu: Avoid pointless checks in menu_select() sched / idle: Drop default_idle_call() fallback from call_cpuidle() cpupower: Fix build error in cpufreq-info cpuidle: Don't enable all governors by default cpuidle: Default to ladder governor on ticking systems time: nohz: Expose tick_nohz_enabled ACPICA: Update version to 20160108 ACPICA: Silence a -Wbad-function-cast warning when acpi_uintptr_t is 'uintptr_t' ACPICA: Additional 2016 copyright changes ACPICA: Reduce regression fix divergence from upstream ACPICA ACPI / video: Add disable_backlight_sysfs_if quirk for the Toshiba Satellite R830 ACPI / video: Revert "thinkpad_acpi: Use acpi_video_handles_brightness_key_presses()" ACPI / video: Document acpi_video_handles_brightness_key_presses() a bit ACPI / video: Fix using an uninitialized mutex / list_head in acpi_video_handles_brightness_key_presses() ACPI / video: Revert "ACPI / video: driver must be registered before checking for keypresses" ACPI / fan: Improve acpi_device_update_power error message ACPI / video: Add disable_backlight_sysfs_if quirk for the Toshiba Portege R700 cpuidle: menu: Fix menu_select() for CPUIDLE_DRIVER_STATE_START == 0 MAINTAINERS: Add devfreq-event entry MAINTAINERS: Add missing git repository and directory for devfreq ...

Each bank (chip select) is dynamically mapped to the CPU-viewed address base via the bus controller. The bus controller must be configured before any access to the bus. This driver parses the "ranges" property of the System Bus node and initialized the bus controller. After the bus becomes ready, devices below it are populated. Note: Each bank can be mapped anywhere in the supported address space; there is nothing preventing us from assigning bank 0 on 0x42000000, 0x43000000, or anywhere as long as such region is not used by others. So, the "ranges" is just one possible software configuration, which does not seem to fit in device tree because device tree is a hardware description language. However, of_translate_address() requires "ranges" in every bus node between CPUs and device mapped on the CPU address space. In other words, "ranges" properties must be statically defined in device tree. After some discussion, I decided the dynamic address reassignment by the driver is too bothersome. Instead, the device tree should provide a reasonable translation setup that the OS can rely on.
