Poweroff the fans when shutting down the system.

2014-12-04i2c: cadence: Set the hardware time-out register to maximum valueVishnu Motghare
Cadence I2C controller has bug wherein it generates invalid read transactions after timeout in master receiver mode. This driver does not use the HW timeout and this interrupt is disabled but the feature itself cannot be disabled. Hence, this patch writes the maximum value (0xFF) to this register. This is one of the workarounds to this bug and it will not avoid the issue completely but reduces the chances of error.

2014-12-04i2c: davinci: generate STP always when NACK is receivedGrygorii Strashko
According to I2C specification the NACK should be handled as follows: "When SDA remains HIGH during this ninth clock pulse, this is defined as the Not Acknowledge signal. The master can then generate either a STOP condition to abort the transfer, or a repeated START condition to start a new transfer." [I2C spec Rev. 6, 3.1.6: http://www.nxp.com/documents/user_manual/UM10204.pdf] Currently the Davinci i2c driver interrupts the transfer on receipt of a NACK but fails to send a STOP in some situations and so makes the bus stuck until next I2C IP reset (idle/enable). For example, the issue will happen during SMBus read transfer which consists from two i2c messages write command/address and read data: S Slave Address Wr A Command Code A Sr Slave Address Rd A D1..Dn A P <--- write -----------------------> <--- read ---------------------> The I2C client device will send NACK if it can't recognize "Command Code" and it's expected from I2C master to generate STP in this case. But now, Davinci i2C driver will just exit with -EREMOTEIO and STP will not be generated. Hence, fix it by generating Stop condition (STP) always when NACK is received. This patch fixes Davinci I2C in the same way it was done for OMAP I2C commit cda2109a26eb ("i2c: omap: query STP always when NACK is received").

2014-12-04[media] img-ir/hw: Fix potential deadlock stopping timerJames Hogan
The end timer is used for switching back from repeat code timings when no repeat codes have been received for a certain amount of time. When the protocol is changed, the end timer is deleted synchronously with del_timer_sync(), however this takes place while holding the main spin lock, and the timer handler also needs to acquire the spin lock. This opens the possibility of a deadlock on an SMP system if the protocol is changed just as the repeat timer is expiring. One CPU could end up in img_ir_set_decoder() holding the lock and waiting for the end timer to complete, while the other CPU is stuck in the timer handler spinning on the lock held by the first CPU. Lockdep also spots a possible lock inversion in the same code, since img_ir_set_decoder() acquires the img-ir lock before the timer lock, but the timer handler will try and acquire them the other way around: ========================================================= [ INFO: possible irq lock inversion dependency detected ] 3.18.0-rc5+ #957 Not tainted --------------------------------------------------------- swapper/0/0 just changed the state of lock: (((&hw->end_timer))){+.-...}, at: [<4006ae5c>] _call_timer_fn+0x0/0xfc but this lock was taken by another, HARDIRQ-safe lock in the past: (&(&priv->lock)->rlock#2){-.....} and interrupts could create inverse lock ordering between them. other info that might help us debug this: Possible interrupt unsafe locking scenario: CPU0 CPU1 ---- ---- lock(((&hw->end_timer))); local_irq_disable(); lock(&(&priv->lock)->rlock#2); lock(((&hw->end_timer))); <Interrupt> lock(&(&priv->lock)->rlock#2); *** DEADLOCK *** This is fixed by releasing the main spin lock while performing the del_timer_sync() call.

2014-12-04[media] img-ir/hw: Always read data to clear bufferDylan Rajaratnam
A problem was found on Polaris where if the unit it booted via the power button on the infrared remote then the next button press on the remote would return the key code used to power on the unit. The sequence is: - The polaris powered off but with the powerdown controller (PDC) block still powered. - Press power key on remote, IR block receives the key. - Kernel starts, IR code is in IMG_IR_DATA_x but neither IMG_IR_RXDVAL or IMG_IR_RXDVALD2 are set. - Wait any amount of time. - Press any key. - IMG_IR_RXDVAL or IMG_IR_RXDVALD2 is set but IMG_IR_DATA_x is unchanged since the powerup key data was never read. This is worked around by always reading the IMG_IR_DATA_x in img_ir_set_decoder(), rather than only when the IMG_IR_RXDVAL or IMG_IR_RXDVALD2 bit is set.

2014-12-04SSB / B44: fix WOL for BCM4401Andrey Skvortsov
Wake On Lan was not working on laptop DELL Vostro 1500. If WOL was turned on, BCM4401 was powered up in suspend mode. LEDs blinked. But the laptop could not be woken up with the Magic Packet. The reason for that was that PCIE was not enabled as a system wakeup source and therefore the host PCI bridge was not powered up in suspend mode. PCIE was not enabled in suspend by PM because no child devices were registered as wakeup source during suspend process. On laptop BCM4401 is connected through the SSB bus, that is connected to the PCI-Express bus. SSB and B44 did not use standard PM wakeup functions and did not forward wakeup settings to their parents. To fix that B44 driver enables PM wakeup and registers new wakeup source using device_set_wakeup_enable(). Wakeup is automatically reported to the parent SSB bus via power.wakeup_path. SSB bus enables wakeup for the parent PCI bridge, if there is any child devices with enabled wakeup functionality. All other steps are done by PM core code.

2014-12-04ARM: at91/defconfig: add DM9000 to at91_dtNicolas Ferre
This chip is present on at91sam9261ek board: add it to the at91_dt_defconfig. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2014-12-04ARM: at91/defconfig: add QT1070 to at91_dtNicolas Ferre
As this touch button driver is used on at91sam9x5ek, it's better to enable it. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2014-12-04ARM: at91/defconfig: add TCB PWM driver selectionNicolas Ferre
This is the selection of the new PWM driver using TC Blocks. This driver is useful so we enable it in both sama5 and at91_dt defconfig files. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2014-12-04ARM: at91/defconfig: add the XDMA driverNicolas Ferre
Add the Atmel eXtended DMA Controller driver option. This driver is first used on SAMA5D4 SoCs and only relevant in sama5_defconfig file. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
