| * ath5k: wake queues on resetBruno Randolf2010-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We can wake all queues after a chip reset since everything should be set up and we are ready to transmit. If we don't do that we might end up starting up with stopped queues, not beeing able to transmit. (This started to happen after "ath5k: clean up queue manipulation" but since periodic calibration also stopped and started the queues this effect was hidden most of the time). This way we can also get rid of the superfluous ath5k_reset_wake() function. Signed-off-by: Bruno Randolf <br1@einfach.org> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | Probably no one has used this driver on big-endian systems, since it was setting up descriptor swapping if CONFIG_BIG_ENDIAN is set, which it never is, since that symbol is not mentioned anywhere else in the kernel source.

* | sfc: Get port number from CS_PORT_NUM, not PCI function numberBen Hutchings2010-06-03
| | | | | | | | | | | | | | | | | | | | | | | | A single shared memory region used to communicate with firmware is mapped into both PCI PFs of the SFC9020 and SFL9021. Drivers must be able to identify which port they are addressing in order to use the correct sub-region. Currently we use the PCI function number, but the PCI address may be virtualised. Use the CS_PORT_NUM register field defined for just this purpose. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* | korina: fix deadlock on RX FIFO overrunPhil Sutter2010-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By calling korina_restart(), the IRQ handler tries to disable the interrupt it's currently serving. This leads to a deadlock since disable_irq() waits for any running IRQ handlers to finish before returning. This patch addresses the issue by turning korina_restart() into a workqueue task, which is then scheduled when needed. Reproducing the deadlock is easily done using e.g. GNU netcat to send large amounts of UDP data to the host running this driver. Note that the same problem (and fix) applies to TX FIFO underruns, but apparently these are less easy to trigger. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: David S.

* | enic: bug fix: make the set/get netlink VF_PORT support symmetricalScott Feldman2010-06-02
| | | | | | | | | | | | | | | | | | | | | | | | To make get/set netlink VF_PORT truly symmetrical, we need to keep track of what items are set and only return those items on get. Previously, the driver wasn't differentiating between a set of attr with a NULL string, for example, and not setting the attr at all. We only want to return the NULL string if the attr was actually set with a NULL string. Otherwise, don't return the attr. Signed-off-by: Scott Feldman <scofeldm@cisco.com> Signed-off-by: David S.

* | bnx2: Fix hang during rmmod bnx2.Michael Chan2010-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The regression is caused by: commit 4327ba435a56ada13eedf3eb332e583c7a0586a9 bnx2: Fix netpoll crash. If ->open() and ->close() are called multiple times, the same napi structs will be added to dev->napi_list multiple times, corrupting the dev->napi_list. This causes free_netdev() to hang during rmmod. We fix this by calling netif_napi_del() during ->close(). Also, bnx2_init_napi() must not be in the __devinit section since it is called by ->open().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rdc321x southbridge PCI device has no MEM PCI resources that we could pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the mem_base argument that we set to NULL. Changing the resources passed to our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use those resources as offsets to the PCI configuration space base address of the southbridge device this is also more adequate.

If the power driver is not able to monitor them (for example, due to the IRQ line not having been wired up on the system) then any charger interrupt will prevent the system suspending for any meaningful amount of time since nothing will ack them. Avoid this issue by manually acknowledging these interrupts when we suspend the WM831x core device if they are masked. If software is actually using the interrupts then they will be unmasked and this change will have no effect.

| | * | mfd: Initialise WM831x IRQ masks on chip even if interrupts not in useMark Brown2010-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that the hardware has interrupts masked if we are not using the interrupt controller on the WM831x by initialising the masks before we check for the setup data required for the IRQ line. This avoids signalling an unused IRQ line and improves the robustness of checks that the IRQ is in use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add touch screen input driver for TPS6507x family of multi-function chips. Uses the TPS6507x MFD driver. No interrupt support due to testing limitations of current hardware. Signed-off-by: Todd Fischer <todd.fischer@ridgerun.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
| | * | mfd: Add TPS6507x supportTodd Fischer2010-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TPS6507x are multi function (PM, touchscreen) chipsets from TI. This commit also changes the corresponding regulator driver from being standalone to an MFD subdevice.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add mfd structure which refrences sub-driver initialization data. For example, for a giving hardware implementation, the voltage regulator sub-driver initialization data provides the mapping betten a voltage regulator and what the output voltage is being used for.
