| * power_supply_sysfs: Handle -ENODATA in a special wayAnton Vorontsov2009-12-02
| | | | | | | | | | | | | | | | | | | | | | There are cases when some device can not report any meaningful value, e.g. TWL4030 charger can report voltage only when charging is active. In these cases drivers will return -ENODATA, and we shouldn't flood kernel log with error messages. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>

| * pcf50633: Query charger status directlyPaul Fertser2009-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Current scheme is fragile and is likely to go off sync, especially on batfull->adapter charging automatic MBC transition. Query the status bit every time we need it instead. We need to export another function to query for USB presence because we can't read anything from PCF50633 (via I2C) inside irq context and that is needed by usb gadgets.

| * pcf50633: Properly reenable charging when the supply conditions changePaul Fertser2009-11-15
| | | | | | | | | | | | | | | | | | | | | | | | If chgmod == BATFULL, setting chgena has no effect. Datasheet says we need to set resume instead but when autoresume is used resume doesn't work. Clear and set chgena instead. This enables a user to force charging by re-plugging USB even when the charger entered Battery Full mode, might be handy before a long trip.

| * pcf50633: Get rid of charging restart software auto-triggeringPaul Fertser2009-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After reaching Battery Full condition MBC state machine switches back into charging mode when the battery voltage falls below 96% of a battery float voltage. The voltage drop in Li-Ion batteries is marginal (1-2%) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 75-80%. That is a desired behaviour recommended by battery manufacturers, don't mess with it. Signed-off-by: Paul Fertser <fercerpav@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
| * pcf50633: introduces battery charging current controlBalaji Rao2009-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new sysfs attribute to allow changing MBC charging limit on the fly independently of usb current limit. It also gets set automatically every time usb current limit is changed. Limiting charging current also prevents violating USB specification in the case when the whole device is shut down and usb current limit is reset to the factory default by the pcf50633 state transition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB drivers that create character devices call usb_register_dev in their probe function. This associates the usb_interface device with that minor number and creates the character device and announces it to the world. However, the driver's probe function is called before the new usb_interface is added to the driver's klist_devices. This is a problem because userspace will respond to the character device creation announcement by opening the character device. The driver's open function will the call usb_find_interface to find the usb_interface associated with that minor number. usb_find_interface will walk the driver's list of devices and find the usb_interface with the matching minor number. Because the announcement happens before the usb_interface is added to the driver's klist_devices, a race condition exists. A straightforward fix is to walk the list of devices on usb_bus_type instead since the device is added to that list before the announcement occurs. bus_find_device calls get_device to bump the reference count on the found device. It is arguable that the reference count should be dropped by the caller of usb_find_interface instead of usb_find_interface, however, the current users of usb_find_interface do not expect this. The original version of this patch only matched against minor number instead of driver and minor number. This version matches against both.

* | | lis3: scale output values to mgSamu Onkalo2009-12-15

Output values from lis3 can be read from sysfs position entry and from input device. Input device can be accessed as event device and as joystick device. Joystick device can be in two modes. Meaning of the output values varies from case to case depending on the chip type and configuration (scale). Only joystick interface in JS_CORR_BROKEN mode returned somehow similar output values in different configurations. Joystick device is in that state by default in case of lis3. Position sysfs entry, input event device and raw joystick device have been little bit broken since meaning of the output values has been varied between 12 and 8 bit devices. Applications which relayed on those methods failed if the chip is different than the expected one. This patch converts output values to mean similar thing in different configurations. Both 8 and 12 bit devices reports now same acceleration values. If somebody implements full scale support to the driver, output values will still mean the same. Scaling factor and input device range must be updated in that case. Joystick interface in JS_CORR_BROKEN mode is not touched by this patch. All other interfaces have different scale after this change. For 12 bit device scaling factor is 0.977 which keeps scaled and unscaled values are quite close to each others. For 8 bit device, scaled values are 18 times bigger than unscaled values.

Control: read selftest sysfs entry Response: "OK x y z" or "FAIL x y z" where x, y, and z are difference between selftest mode and normal mode. Test is passed when values are within acceptance limit values. Acceptance limits are provided via platform data. See chip spesifications for acceptance limits. If limits are not properly set, OK / FAIL decision is meaningless. However, userspace application can still make decision based on the numeric x, y, z values. Selftest is meant for HW diagnostic purposes. It is not meant to be called during normal use of the chip. It may cause false interrupt events. Selftest mode delays polling of the normal results but it doesn't cause wrong values. Chip must be in static state during selftest. Any acceration during the test causes most probably failure.

This must happen before the data transfer command is sent. A new function is able to differentiate MCI2 code and is based on knowledge of processor id (cpu_is_xxx()).

Add a module parameter to set whether cards are assumed removable or non-removable, with the default set by CONFIG_MMC_UNSAFE_RESUME. In general, it is not possible to tell whether a card present in an MMC slot after resume is the same that was there before suspend. So there are two possible behaviours, each of which will cause data loss in some cases: CONFIG_MMC_UNSAFE_RESUME=n (default): Cards are assumed to be removed during suspend. Any filesystem on them must be unmounted before suspend; otherwise, buffered writes will be lost. CONFIG_MMC_UNSAFE_RESUME=y: Cards are assumed to remain present during suspend. They must not be swapped during suspend; otherwise, buffered writes will be flushed to the wrong card. Currently the choice is made at compile time and this allows that to be overridden at module load time.

The variables which store the value returned by edma_alloc_channel() have to be 32 bit wide now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for MMC/SD controller driver for all DaVinci family SoC. This patch supports davinci family SoC's DM6446, DM355, DM365 and DA830/OMAPL137. The patch has been tested on DM355 EVM.

* | | sdio: rework cis tuple parsingAlbert Herranz2009-12-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework the current CIS tuple parsing code, reusing the existing infrastructure and providing an easy way to add new CISTPL_FUNCE parsers by TPLFE_TYPE. Valid known CIS tuples are now silently queued for the SDIO function driver when not parsed/processed (-EILSEQ) by the SDIO core. Unknown CIS tuples (-ENOENT) are queued too for the SDIO function driver without aborting the initialization, but emit a warning in the kernel log. CISTPL_FUNCE tuples can be "whitelisted" now by adding a matching entry to the cis_tpl_funce_list table.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than have the EDD depend on !ia64 (and assuming that only ia64, x86, x86_64 will be including this Kconfig), have EDD depend on the only arches which can support this code. This should allow all other arches to cleanly include the firmware Kconfig. Also simplify the x86 string used by FIRMWARE_MEMMAP to match EDD.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently, We marked strstrip() as must_check. because it was frequently misused and it should be checked. However, we found one exception. scsi/ipr.c intentionally ignore return value of strstrip. Because it wishes to keep the whitespace at the beginning. Thus we need to keep with and without checked whitespace trim function. This patch adds a new strim() and changes ipr.c to use it.
