wifi: mac80211: simplify non-chanctx drivers There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.

wifi: mac80211: add wake_tx_queue callback to drivers mac80211 is fully switching over to the internal TX queue (iTXQ) implementation. Update all drivers not yet providing the now mandatory wake_tx_queue() callback. As an side effect the netdev interfaces of all updated drivers will switch to the noqueue qdisc.

rt2x00: pci: use generic power management Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. The callbacks make use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device() and pci_set_power_state() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use dev_get_drvdata() to get drv data. The .suspend() callback is invoking rt2x00lib_suspend() which needs to be modified as generic rt2x00pci_suspend() has no pm_message_t type argument, passed to it, which is required by it according to its declaration. Although this variable remained unused in the function body. Hence, remove it from the function definition & declaration. rt2x00lib_suspend() is also invoked by rt2x00usb_suspend() and rt2x00soc_suspend(). Thus, modify the functional call accordingly in their function body. Earlier, .suspend() & .resume() were exported and were used by the following drivers: - drivers/net/wireless/ralink/rt2x00/rt2400pci.c - drivers/net/wireless/ralink/rt2x00/rt2500pci.c - drivers/net/wireless/ralink/rt2x00/rt2800pci.c - drivers/net/wireless/ralink/rt2x00/rt61pci.c Now, we only need to bind "struct dev_pm_ops" variable to "struct pci_driver". Thus, make the callbacks static. Declare an "extern const struct dev_pm_ops" variable and bind PM callbacks to it. Now, export the variable instead and use it in respective drivers. Compile-tested only.

rt2800: add helpers for reading dma done index For mmio we do not properlly trace dma done Q_INDEX_DMA_DONE index for TX queues. That would require implementing INT_SOURCE_CSR_*_DMA_DONE interrupts, what is rather not worth to do due to adding extra CPU load (small but still somewhat not necessary otherwise). We can just read TX DMA done indexes from registers directly. What will be used by watchdog. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
