2011-01-14mfd: Convert 88PM860x driver to new irq_ APIsMark Brown1-21/+15
The interrupt controller APIs are being updated to pass a struct irq_data rather than the interrupt number. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-01-14mfd: Staticise internal functions in HTC I2CCPLD driverMark Brown1-5/+5
Most of these are GPIO operations, though a couple are just internal only functions. Signed-off-by: Mark Brown <[email protected]> Acked-by: Cory Maccarrone <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-01-14mfd: Use NULL to initialise NULL pointers in ab8500-debugfsMark Brown1-7/+7
Partly for coding style reasons, but mostly because sparse warns on it. Signed-off-by: Mark Brown <[email protected]> Acked-by: Mattias Wallin <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-01-14mfd: Correct ASIC3 IRQ_OWM resource setupMark Brown1-1/+1
We should specify both a start and an end for the IRQ range rather than initialise the start twice. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-01-14mfd: Staticise unexported symbols in ASIC3Mark Brown1-2/+2
There's no use of either of these outside of the driver so they can be declared static. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-01-14mfd: Remove tps6586x device ID checkStephen Warren1-7/+1
... and convert it to a dev_info print at probe time. There are many variants of this chip with different values of VERSIONCRC. The set of values is large, and not useful to enumerate. All are SW compatible. The difference lies in default settings of the various power rails, and other similar differences. The driver, or clients of the driver, shouldn't be affected by this, since all rails should be programmed into the desired state in all cases for correct operation.

2011-01-14mfd: ab8500-core wake up from suspendMattias Wallin1-1/+2
This patch makes the system wake up from suspend when an ab8500 interrupt occur. This can for example be USB cable insert or an RTC alarm. Signed-off-by: Mattias Wallin <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-01-14mfd: Export ab8500 chip id to sysfsMattias Wallin1-0/+25

2011-01-14gpio/misc: Add MODULE_ALIAS entries for CS5535 functionsAndres Salomon2-0/+2
This adds MODULE_ALIAS entries to the various cs5535 subdevice modules; this allows the modules to automatically be loaded when cs5535-mfd loads. Signed-off-by: Andres Salomon <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-01-14misc: Convert cs5535-mfgpt from pci device to platform deviceAndres Salomon1-52/+21

2011-01-14mfd: Implement runtime PM for WM8994 core driverMark Brown1-23/+23
Allow the WM8994 to completely power off, including disabling the LDOs if they are software controlled, when it goes idle. The CODEC subdevice controls activity for the MFD as a whole. If the GPIOs need to be used while the device is active runtime PM should be disabled for the device by machine specific code.

2011-01-14mfd: Provide pm_runtime_no_callbacks flag in cell dataMark Brown2-0/+10
Allow MFD cells to have pm_runtime_no_callbacks() called on them during registration. This causes the runtime PM framework to ignore them, allowing use of runtime PM to suspend the device as a whole even if not all drivers for the MFD can usefully implement runtime PM. For example, RTCs are likely to run continuously regardless of the power state of the system. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>

2011-01-14block cfq: compensate preempted queue even if it has no slice assignedShaohua Li1-4/+15
If a queue is preempted before it gets slice assigned, the queue doesn't get compensation, which looks unfair. For such queue, we compensate it for a whole slice. Signed-off-by: Shaohua Li <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2011-01-14block cfq: make queue preempt work for queues from different workloadShaohua Li1-0/+9
I got this: fio-874 [007] 2157.724514: 8,32 m N cfq874 preempt fio-874 [007] 2157.724519: 8,32 m N cfq830 slice expired t=1 fio-874 [007] 2157.724520: 8,32 m N cfq830 sl_used=1 disp=0 charge=1 iops=0 sect=0 fio-874 [007] 2157.724521: 8,32 m N cfq830 set_active wl_prio:0 wl_type:0 fio-874 [007] 2157.724522: 8,32 m N cfq830 Not idling. st->count:1 cfq830 is an async queue, and preempted by a sync queue cfq874. But since we have cfqg->saved_workload_slice mechanism, the preempt is a nop. Looks currently our preempt is totally broken if the two queues are not from the same workload type. Below patch fixes it. This will might make async queue starvation, but it's what our old code does before cgroup is added.

2011-01-13r8169: keep firmware in memory.françois romieu1-12/+31
The firmware agent is not available during resume. Loading the firmware during open() (see eee3a96c6368f47df8df5bd4ed1843600652b337) is not enough. close() is run during resume through rtl8169_reset_task(), whence the mildly natural release of firmware in the driver removal method instead. It will help with http://bugs.debian.org/609538.

2011-01-13USB CDC NCM: Don't deref NULL in cdc_ncm_rx_fixup() and don't use ↵Jesper Juhl1-1/+3
uninitialized variable. skb_clone() dynamically allocates memory and may fail. If it does it returns NULL. This means we'll dereference a NULL pointer in drivers/net/usb/cdc_ncm.c::cdc_ncm_rx_fixup(). As far as I can tell, the proper way to deal with this is simply to goto the error label. Furthermore gcc complains that 'skb' may be used uninitialized: drivers/net/usb/cdc_ncm.c: In function ‘cdc_ncm_rx_fixup’: drivers/net/usb/cdc_ncm.c:922:18: warning: ‘skb’ may be used uninitialized in this function and I believe it is right. On the line where we pr_debug("invalid frame detected (ignored)" ... we are using the local variable 'skb' but nothing has ever been assigned to that variable yet. I believe the correct fix for that is to use 'skb_in' instead. Signed-off-by: Jesper Juhl <[email protected]> Signed-off-by: David S. Miller <[email protected]>
