* Input: psmouse - fix Synaptics detection when protocol is disabledDaniel Drake2010-01-07
| | | | | | | | | | | | | | | | | | | | | For configurations where Synaptics hardware is present but the Synaptics extensions support is not compiled in, the mouse is reprobed and a new device is allocated on every suspend/resume. During probe, psmouse_switch_protocol() calls psmouse_extensions() with set_properties=1. This calls the dummy synaptics_init() which returns an error code, instructing us not to use the synaptics extensions. During resume, psmouse_reconnect() calls psmouse_extensions() with set_properties=0, in which case call to synaptics_init() is bypassed and PSMOUSE_SYNAPTICS is returned. Since the result is different from previous attempt psmouse_reconnect() fails and full re-probe happens. Fix this by tweaking the set_properties=0 codepath in psmouse_extensions() to be more careful about offering PSMOUSE_SYNAPTICS extensions.

* Input: evdev - be less aggressive about sending SIGIO notifiesAdam Jackson2010-01-06
| | | | | | | | | | | | | | | | | | When using realtime signals, we'll enqueue one signal for every event. This is unfortunate, because (for example) keyboard presses are three events: key, msc scancode, and syn. They'll be enqueued fast enough in kernel space that all three events will be ready to read by the time userspace runs, so the first invocation of the signal handler will read all three events, but then the second two invocations still have to run to do no work. Instead, only send the SIGIO notification on syn events. This is a slight abuse of SIGIO semantics, in principle it ought to fire as soon as any events are readable. But it matches evdev semantics, which is more important since SIGIO is rather vaguely defined to begin with.

* Input: serio - fix potential deadlock when unbinding driversEric W. Biederman2010-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs_remove_group() waits for sysfs attributes to be removed, therefore we do not need to worry about driver-specific attributes being accessed after driver has been detached from the device. In fact, attempts to take serio->drv_mutex in attribute methods may lead to the following deadlock: sysfs_read_file() fill_read_buffer() sysfs_get_active_two() psmouse_attr_show_helper() serio_pin_driver() serio_disconnect_driver() mutex_lock(&serio->drv_mutex); <--------> mutex_lock(&serio_drv_mutex); psmouse_disconnect() sysfs_remove_group(... psmouse_attr_group); .... sysfs_deactivate(); wait_for_completion(); Fix this by removing calls to serio_[un]pin_driver() and functions themselves and using driver-private mutexes to serialize access to attribute's set() methods that may change device state.

| | | | | | | | | | | | | | | | The commit 9e68177ef93b2f34eee5a1e1707bceef4b9ba69c changed 'gain' from signed to unsigned to fix an issue with rumble effect calculation, however it introduced problems when calculating constant effects. Having 'gain' being unsigned int was an unfortunate choice since it dominates all implicit type conversions causing everything to be treated as unsigned int.

Second, make the logic a bit more explicit so that gcc can statically prove that the copy_from_user() is safe. Once the condition of the beyond-end filepointer is eliminated, the copy is safe but gcc can't prove it, causing build failures for i386 allyesconfig. Third, eliminate the entirely superfluous variable "len", and just use the passed-in variable "count" instead. Signed-off-by: H.

This patch fixes out-of-bounds writes (see URL above) by adding per-CPU msr structs which are used on the respective cores.

Full duplex, spi mode 0-3, active high cs, 3-wire and lsb first should all be supported, but the driver has so far only been tested with "mmc_spi". The MSIOF hardware comes with 32-bit FIFOs for receive and transmit, and this driver simply breaks the SPI messages into FIFO-sized chunks. The MSIOF hardware manages the pins for clock, receive and transmit (sck/miso/mosi), but the chip select pin is managed by software and must be configured as a regular GPIO pin by the board code. Performance wise there is still room for improvement, but on a Ecovec board with the built-in sh7724 MSIOF0 this driver gets Mini-sd read speeds of about half a megabyte per second. Future work include better clock setup and merging of 8-bit transfers into 32-bit words to reduce interrupt load and improve throughput.

If gpio_request() fails and the previous chipselect was a negative number, the while loop is endless (i is never decremented). Also, the error loop would never call gpio_free on chipselect[0]. And finally, the error message was missing an endline. Signed-off-by: John Ogness <john.ogness@linutronix.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
| | * | | spi/i.mx: drain MXC SPI transfer buffer when probing deviceDaniel Mack2009-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the MX31litekit, the bootloader seems to communicate with the MC13783 PMIC chip before booting Linux. However, it does not flush all the buffers properly after that, which makes the imx-spi driver read bogus data when probing the MC13783. Fix that by draining the SPI receive buffer on startup.

| | * | | xilinx_spi: add support for the DS570 IP.Richard Röjfors2009-12-08

It's register compatible with the DS464, but adds support for 8/16/32 SPI. The 8/16/32 support is added by attaching callbacks reading/writing the proper amount of data. To indicate to the driver which amount of bits to use a new field is introduced in the platform data struct.
