| * Regulator: add suspend-finish API for regulator core.MyungJoo Ham2011-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The regulator core had suspend-prepare that turns off the regulators when entering a system-wide suspend. However, it did not have suspend-finish that pairs with suspend-prepare and the regulator core has assumed that the regulator devices and their drivers support autonomous recover at resume. This patch adds regulator_suspend_finish that pairs with the previously-existed regulator_suspend_prepare. The function regulator_suspend_finish turns on the regulators that have always_on set or positive use_count so that we can reset the regulator states appropriately at resume. In regulator_suspend_finish, if has_full_constraints, it disables unnecessary regulators.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables IRQ handling for MAX8997/8966 chips. Please note that Fuel-Gauge-related IRQs are not implemented in this initial release. The fuel gauge module in MAX8997 is identical to MAX17042, which is already in Linux kernel. In order to use the already-existing MAX17042 driver for fuel gauge module in MAX8997, the main interrupt handler of MAX8997 should relay related interrupts to MAX17042 driver. However, in order to do this, we need to modify MAX17042 driver as well because MAX17042 driver does not have any interrupt handlers for now. We are not going to implement this in this initial release as it is not crucial in basic operations of MAX8997.

| * | mfd: Add mfd_clone_cell(), convert cs5535-mfd/olpc-xo1 to itAndres Salomon2011-03-26
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace mfd_shared_platform_driver_register with mfd_clone_cell. The former was called by an mfd client, and registered both a platform driver and device. The latter is called by an mfd driver, and registers only a platform device. The downside of this is that mfd drivers need to be modified whenever new clients are added that share a cell; the upside is that it fits Linux's driver model better. It's also simpler. This also converts cs5535-mfd/olpc-xo1 from the old API. cs5535-mfd now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to them via platform drivers.

NOTE! This merge commit was created to fix compilation error. The block tree was merged upstream and removed the 'elv_queue_empty()' function which the new 'mtdswap' driver is using. So a simple merge of the mtd tree with upstream does not compile. And the mtd tree has already be published, so re-basing it is not an option. To fix this unfortunate situation, I had to merge upstream into the mtd-2.6.git tree without committing, put the fixup patch on top of this, and then commit this. The result is that we do not have commits which do not compile. In other words, this merge commit "merges" 3 things: the MTD tree, the upstream tree, and the fixup patch.
| * | | mtd: nand: add software BCH ECC supportIvan Djelic2011-03-11

It does so by adding a new ecc mode (NAND_ECC_SOFT_BCH) for use by board drivers, and a new Kconfig option to enable BCH support. It relies on the generic BCH library introduced in a previous patch. When a board driver uses mode NAND_ECC_SOFT_BCH, it should also set fields chip->ecc.size and chip->ecc.bytes to select BCH ecc data size and required error correction capability. See nand_bch_init() documentation for details. It has been tested on the following platforms using mtd-utils, UBI and UBIFS: x86 (with nandsim), arm926ejs.

Binary BCH (Bose-Chaudhuri-Hocquenghem) codes are widely used to correct errors in NAND flash devices requiring more than 1-bit ecc correction; they are generally better suited for NAND flash than RS codes because NAND bit errors do not occur in bursts. Latest SLC NAND devices typically require at least 4-bit ecc protection per 512 bytes block. This library provides software encoding/decoding, but may also be used with ASIC/SoC hardware BCH engines to perform error correction. It is being currently used for this purpose on an OMAP3630 board (4bit/8bit HW BCH). It has also been used to decode raw dumps of NAND devices with on-die BCH ecc engines (e.g. Micron 4bit ecc SLC devices). Latest NAND devices (including SLC) can exhibit high error rates (typically a dozen or more bitflips per hour during stress tests); in order to minimize the performance impact of error correction, this library implements recently developed algorithms for fast polynomial root finding (see bch.c header for details) instead of the traditional exhaustive Chien root search; a few performance figures are provided below: Platform: arm926ejs @ 468 MHz, 32 KiB icache, 16 KiB dcache BCH ecc : 4-bit per 512 bytes Encoding average throughput: 250 Mbits/s Error correction time (compared with Chien search): average worst average (Chien) worst (Chien) ---------------------------------------------------------- 1 bit 8.5 µs 11 µs 200 µs 383 µs 2 bit 9.7 µs 12.5 µs 477 µs 728 µs 3 bit 18.1 µs 20.6 µs 758 µs 1010 µs 4 bit 19.5 µs 23 µs 1028 µs 1280 µs In the above figures, "worst" is meant in terms of error pattern, not in terms of cache miss / page faults effects (not taken into account here). The library has been extensively tested on the following platforms: x86, x86_64, arm926ejs, omap3630, qemu-ppc64, qemu-mips.

If a device such as an asynchronous flash needs to be attached to the EMIFA, then either GPIO pins or a chip select may be used to control the flash device's upper address lines. This patch adds support for the NOR flash on the OMAP-L137/ AM17x user interface daughter board using the latch-addr-flash MTD mapping driver which allows flashes to be partially physically addressed. The upper address lines are set by a board specific code which is a separate patch.

This patch presents two functions that are used to allocate or release HW resources for using blue flame; the caller need to supply a struct mlx4_bf object when allocating resources. Consumers that make use of this API should post doorbells to the UAR object pointed by the initialized struct mlx4_bf; Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: David S.

This is due to commit 97c145f7c87453cec90e91238fba5fe2c1561b32 (PCI: read current power state at enable time) which resets dev->current_state to D0. Due to this the call to pcie_aspm_pm_state_change() is never made. Note the equality check (below) that returns early: ./drivers/pci/pci.c: pci_raw_set_pci_power_state() 546 /* Check if we're already there */ 547 if (dev->current_state == state) 548 return 0; Therefore OSPM never configures the PCIe links for ASPM to turn them "on". Fix it by configuring ASPM from the pci_enable_device() code path. This also allows a driver such as the e1000e networking driver a chance to disable ASPM (L0s, L1), if need be, prior to enabling the device. A driver may perform this action if the device is known to mis-behave wrt ASPM. Signed-off-by: Naga Chumbalkar <nagananda.chumbalkar@hp.com> Acked-by: Rafael J.

In the former case we should not report ASPM support to the BIOS through ACPI _OSC, but in the latter case we should do that. Introduce pcie_aspm_support_enabled() that can be used by acpi_pci_root_add() to determine whether or not it should report ASPM support to the BIOS through _OSC.

The driver expects to be provided with a read callback function through its platform data. The read function is assumed to do the lowlevel HDQ handling and read out the value of a certain register.
