2019-02-28mt76: fix a leaked reference by adding a missing of_node_putWen Yang1-8/+16
The call to of_find_node_by_phandle returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage.

2019-02-26mt76usb: use synchronous msg for mcu command responsesStanislaw Gruszka6-74/+15
Use usb_bulk_msg for reading MCU command responses. This simplify code a lot. Together with 97a3005759c ("mt76usb: allow mt76u_bulk_msg be used for reads") it also fix possible problems with rx data buffers not being aligned and contained within single page. After doing page_frag_alloc(1024) consecutive page_frag_alloc(PAGE_SIZE) will alloc PAGE_SIZE buffer at PAGE_SIZE - 1024 offset.

It needs to be always enabled for 76x2 and conditionally enabled/disabled for 76x0. Since mt76x2_mac_stop clears this bit, ensure that it is enabled in mt76x02_edcca_init Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-02-26mt76: mt76x02: fix ED/CCA enabling/disablingFelix Fietkau8-16/+14
ED/CCA needs to be disable before stopping the MAC to avoid hangs from tx being blocked. It must only be enabled again after the MAC has been started again. In many places this wasn't done properly, so fix this by always clearing the relevant ED/CCA bits in mt76x2_mac_stop and set it up again after channel change or calibration is done Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-26mt76: mt76x02: issue watchdog reset on MCU request timeoutFelix Fietkau3-9/+21
MCU request timeout usually indicates that the device is no longer responsive, and it usually does not recover without a reset Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-26mt76: mt76x02: only reset beacon drift counter when enabling beaconsFelix Fietkau2-1/+3
When the timer is already running, there is no need to reset the counter, because the drift will remain the same. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-26mt76: mt76x02: fix beacon timer issueFelix Fietkau1-3/+3
When mt76x0 and mt76x2 beacon code was unified, it changed the order in which beacon enable and beacon interval are configured. Configuring beacon enable before beacon interval can in some cases cause problems with the beacon timer, leading to clients not waking up properly from powersave mode. Fix this by changing the order back to interval first, then enable.

Modify mt76x0_get_tx_power_per_rate and mt76x0_get_power_info signature in order to compute tx power for non-operating channels Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76x0: phy: report target_power in debugfsLorenzo Bianconi1-0/+1
Initialize target_power variable in mt76x0_phy_set_txpower in order to report target_power in debugfs Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: change the return type of mt76_dma_attach()Ryder Lee2-3/+2
There is no need to retun 0 in mt76_dma_attach(), so switch it to void. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76x2: remove mt76x2_alloc_device routineLorenzo Bianconi3-33/+20
Remove mt76x2_alloc_device since it just runs mt76_alloc_device. Move mt76_alloc_device call in mt76x2_probe Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76x0: remove mt76x0u_alloc_device routineLorenzo Bianconi4-38/+24
Remove mt76x0u_alloc_device since it just runs mt76_alloc_device. Move mt76_alloc_device call in mt76x0u_probe and in mt76x0e_probe Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76x2u: remove mt76x2u_alloc_device routineLorenzo Bianconi3-30/+18
Remove mt76x2u_alloc_device since it just runs mt76_alloc_device. Move mt76_alloc_device call in mt76x2u_probe Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: move alloc_device common code in mt76_alloc_deviceLorenzo Bianconi5-13/+14
Move mt76x{0,2} alloc_device common code in mt76_alloc_device and remove duplicated code Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: increase ED/CCA tx block thresholdFelix Fietkau1-1/+1
Block only when the busy time reaches 92%, as lower values can be reached with heavy 802.11 traffic as well. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: measure the time between mt76x02_edcca_check runsFelix Fietkau2-2/+10
Based on system load and time needed by other calibration runs, the time between dev->mac_work runs can vary quite a bit. Calculate busy time based on the actual time difference in order to avoid potentially over-estimating busy time, which could lead to unnecessary tx blocking.

2019-02-18mt76: clear CCA timer stats in mt76x02_edcca_initFelix Fietkau1-0/+3
Avoid triggering too early Signed-off-by: Felix Fietkau <nbd@nbd.name>
