2013-04-01spi/omap-mcspi: check condition also after timeoutSebastian Andrzej Siewior
It is possible that the handler gets interrupted after checking the status. After it resumes the time out is due but the condition it was waiting for might be true as well. Therefore it is necessary to check the condition in case of an time out to be sure that the condition is not true after the time passed by.

2013-04-01spi: add ability to validate xfer->bits_per_word in SPI coreStephen Warren
Allow SPI masters to define the set of bits_per_word values they support. If they do this, then the SPI core will reject transfers that attempt to use an unsupported bits_per_word value.

2013-03-12spi: add driver for BCM2835Chris Boot
The BCM2835 contains two forms of SPI master controller (one known simply as SPI0, and the other known as the "Universal SPI Master", in the auxilliary block) and one form of SPI slave controller. This patch adds support for the SPI0 controller. This driver is taken from Chris Boot's repository at git://github.com/bootc/linux.git rpi-linear as of commit 6de2905 "spi-bcm2708: fix printf with spurious %s". In the first SPI-related commit there, Chris wrote: Thanks to csoutreach / A Robinson for his driver which I used as an inspiration. You can find his version here: http://piface.openlx.org.uk/raspberry-pi-spi-kernel-driver-available-for Changes made during upstreaming: * Renamed bcm2708 to bcm2835 as per upstream naming for this SoC. * Removed support for brcm,realtime property. * Increased transfer timeout to 30 seconds. * Return IRQ_NONE from the IRQ handler if no interrupt was handled. * Disable TA (Transfer Active) and clear FIFOs on a transfer timeout. * Wrote device tree binding documentation. * Request unnamed clock rather than "sys_pclk"; the DT will provide the correct clock. * Assume that tfr->speed_hz and tfr->bits_per_word are always set in bcm2835_spi_start_transfer(), bcm2835_spi_transfer_one(), so no need to check spi->speed_hz or tft->bits_per_word. * Re-ordered probe() to remove the need for temporary variables. * Call clk_disable_unprepare() rather than just clk_unprepare() on probe() failure. * Don't use devm_request_irq(), to ensure that the IRQ doesn't fire after we've torn down the device, but not unhooked the IRQ. * Moved probe()'s call to clk_prepare_enable() so we can be sure the clock is enabled if the IRQ handler fires immediately. * Remove redundant checks from bcm2835_spi_check_transfer() and bcm2835_spi_setup(). * Re-ordered IRQ handler to check for RXR before DONE. Added comments to ISR. * Removed empty prepare/unprepare implementations. * Removed use of devinit/devexit. * Added BCM2835_ prefix to defines.

2013-03-09Atmel MXT touchscreen: increase reset timeoutsLinus Torvalds
There is a more complete atmel patch-series out by Nick Dyer that fixes this and other things, but in the meantime this is the minimal thing to get the touchscreen going on (at least my) Pixel Chromebook. Not that I want my dirty fingers near that beautiful screen, but it seems that a non-initialized touchscreen will also end up being a constant wakeup source, so you have to disable it to go to sleep. And it's easier to just fix the initialization sequence. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This same driver can be used by atmel based touchscreens and touchpads (buttonpads). Platform data may specify a device is a touchpad using the is_tp flag. This will cause the driver to perform some touchpad specific initializations, such as: * register input device name "Atmel maXTouch Touchpad" instead of Touchscreen. * register BTN_LEFT & BTN_TOOL_* event types. * register axis resolution (as a fixed constant, for now) * register BUTTONPAD property * process GPIO buttons using reportid T19 Input event GPIO mapping is done by the platform data key_map array. key_map[x] should contain the KEY or BTN code to send when processing GPIOx from T19. To specify a GPIO as not an input source, populate with KEY_RESERVED, or 0.

2013-03-08drm/mgag200: Bug fix: Renesas board now selects native resolution.Julia Lemire
Renesas boards were consistently defaulting to the 1024x768 resolution, regardless of the native resolution of the monitor plugged in. It was determined that the EDID of the monitor was not being read. Since the DAC is a shared line, in order to read from or write to it we must take control of the DAC clock. This can be done by setting the proper register to one. This bug fix sets the register MGA1064_GEN_IO_CTL2 to one. The DAC control line can be used to determine whether or not a new monitor has been plugged in. But since the hotplug feature is not one we will support, it has been decided to simply leave the register set to one.

2013-03-07HID: logitech-dj: do not directly call hid_output_raw_report() during probeBenjamin Tissoires
hid_output_raw_report() makes a direct call to usb_control_msg(). However, some USB3 boards have shown that the usb device is not ready during the .probe(). This blocks the entire usb device, and the paired mice, keyboards are not functional. The dmesg output is the following: [ 11.912287] logitech-djreceiver 0003:046D:C52B.0003: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-2/input2 [ 11.912537] logitech-djreceiver 0003:046D:C52B.0003: logi_dj_probe:logi_dj_recv_query_paired_devices error:-32 [ 11.912636] logitech-djreceiver: probe of 0003:046D:C52B.0003 failed with error -32 Relying on the scheduled call to usbhid_submit_report() fixes the problem. related bugs: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1072082 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1039143 https://bugzilla.redhat.com/show_bug.cgi?id=840391 https://bugzilla.kernel.org/show_bug.cgi?id=49781 Reported-and-tested-by: Bob Bowles <bobjohnbowles@gmail.com> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
