2009-01-04mfd: Pass driver_data onto child devicesMark Brown
The MFD cell structure provides a driver_data field but doesn't pass it on to the child devices when instantiating them - do that. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
2009-01-04mfd: Fix twl4030-core.c build errorSamuel Ortiz
This is a fix for: twl4030-core.c:(.text+0x16a797): undefined reference to `clk_get_rate' twl4030-core.c:(.text+0x16a797): undefined reference to `clk_put' on x86 and x86_64, as the clock API is not defined on those platforms. Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
2009-01-04mfd: twl4030 regulator bug fixesDavid Brownell
This contains two bugfixes to the initial twl4030 regulator support patch related to USB: (a) always overwrite the old list of consumers ... else the regulator handles all use the same "usb1v5" name; (b) don't set up the "usbcp" regulator, which turns out to be managed through separate controls, usually ULPI directly from the OTG controller.

2009-01-04mfd: twl4030: create some regulator devicesDavid Brownell
Initial code to create twl4030 voltage regulator devices, using the new regulator framework. Note that this now starts to care what name is used to declare the TWL chip: - TWL4030 is the "old" chip; newer ones have a bigger variety of VAUX2 voltages. - TWL5030 is the core "new" chip; TPS65950 is its catalog version. - The TPS65930 and TPS65920 are cost-reduced catalog versions of TWL5030 parts ... fewer regulators, no battery charger, etc. Board-specific regulator configuration should be provided, listing which regulators are used and their constraints (e.g. 1.8V only). Code that could ("should"?) leverage the regulator stuff includes TWL4030 USB transceiver support and MMC glue, LCD support for the 3430SDP and Labrador boards, and S-Video output.

2009-01-04mfd: twl4030: cleanup symbols and OMAP dependencyDavid Brownell
Finish removing dependency of TWL driver stack on platform-specific IRQ definitions ... and remove the build dependency on OMAP. This lets the TWL4030 code be included in test builds for most platforms, and will make it easier for non-OMAP folk to update most of this code for new APIs etc. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
2009-01-04mfd: twl4030: simplified child creation codeDavid Brownell
Minor cleanup to twl4030-core: define a helper function to populate a single child node, and use it to replace six inconsistent versions of the same logic. Both object and source code shrink. As part of this, some devices now have more IRQ resources: battery charger, keypad, ADC, and USB transceiver. That helps to remove some irq #defines that block the children's drivers code from compiling on non-OMAP platforms.

2009-01-04mfd: Refactor WM8350 chip identificationMark Brown
Since the WM8350 driver was originally written the semantics for the identification registers of the chip have been clarified, allowing us to do an exact match on all the fields. This avoids mistakenly running on unsupported hardware. Also change to using the datasheet names more consistently for legibility and fix a printk() that should be dev_err().

2009-01-04power_supply: Add support for WM8350 PMUMark Brown
This patch adds support for the PMU provided by the WM8350 which implements battery, line and USB supplies including a battery charger. The hardware functions largely autonomously, with minimal software control required to initiate fast charging. Support for configuration of the USB supply is not yet implemented. This means that the hardware will remain in the mode configured at startup, by default limiting the current drawn from USB to 100mA. This driver was originally written by Liam Girdwood with subsequent updates for submission by Mark Brown.

2009-01-04ALSA: sound/usb: Use negated usb_endpoint_xfer_control, etcJulia Lawall
This patch extends 42a6e66f1e40a930d093c33ba0bb9d8d8e4555ed by using usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk, and usb_endpoint_xfer_int in the negated case as well. This patch also rewrites some calls to usb_endpoint_dir_in as negated calls to !usb_endpoint_dir_out, and vice versa, to better correspond to the intent of the original code.

2009-01-04intel-iommu: fix build error with INTR_REMAP=y and DMAR=nIngo Molnar
dmar.o can be built in the CONFIG_INTR_REMAP=y case but iommu_calculate_agaw() is only available if VT-d is built as well. So create an inline version of iommu_calculate_agaw() for the !CONFIG_DMAR case. The iommu->agaw value wont be used in this case, but the code is cleaner (has less #ifdefs) if we have it around unconditionally. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-01-05ext4: provide function to release metadata pages under memory pressureToshiyuki Okajima
Pages in the page cache belonging to ext4 data files are released via the ext4_releasepage() function specified in the ext4 inode's address_space_ops. However, metadata blocks (such as indirect blocks, directory blocks, etc) are managed via the block device address_space_ops, and they can not be released by try_to_free_buffers() if they have a journal head attached to them. To address this, we supply a release_metadata function which calls jbd2_journal_try_to_free_buffers() function to free the metadata, and which is called by the block device's blkdev_releasepage() function.

2009-01-04HID: add proper support for pensketch 12x9 tabletMatt Helsley
The Genius PenSketch 12x9 tablet has a puck (labeled a "Tablet Mouse") in addition to a pen. Without registering a quirk the tablet appears to be a single input device that reports the wrong axis information in /proc/bus/input/devices, and sends incorrect events (e.g. ABS_Z instead of ABS_Y). This information confuses the X evdev driver and makes the device impossible to use. The quirk fixes events and splits the device into multiple input event devices so that at least the puck is useful.

2009-01-04HID: hiddev cleanup -- handle all error conditions properlyOliver Neukum
This is a cleanup of hiddev and fixes the following issues: - thread safety by locking in read & ioctl, introducing a per device mutex - race between ioctl and disconnect, introducing a flag and locking in form of a per low level device mutex - race between open and other methods, making sure only successfully opened devices are put on the list, changing order of events - range checking both upper and lower limits of the minor range - make sure further calls to open fail for unplugged devices even if the device still has opened files - error checking for low level open - possible loss of wakeup events, using standard waiting macros - race in initialisation by moving registration after full initialisation Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2009-01-04HID: struct device - replace bus_id with dev_name(), dev_set_name()Kay Sievers
This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

2009-01-04HID: automatically call usbhid_set_leds in usbhid driverAlan Stern
This patch (as1146c) makes usbhid automatically call usbhid_set_leds() for any device that supports the keyboard boot protocol. In theory this should be perfectly safe. BIOSes send the LED output report as part of their normal device initialization, so any keyboard device supporting the boot protocol has to be able to handle it. As a side effect, the hid-dell and hid-bright drivers are no longer needed, and the Logitech keyboard driver can be removed from hid-lg.
