2019-05-01mt76usb: use usb_dev private dataStanislaw Gruszka
Setup usb device private data. This allows to remove mt76u_buf->dev and simplify some routines as no longer we need to get usb device through usb interface. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76: unify set_timStanislaw Gruszka
All mt76 drivers (now also USB drivers) require empty .set_tim callback. Add it to common mt76 module and use on all drivers. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76x02u: add mt76_release_buffered_framesStanislaw Gruszka
Create software MT_TXQ_PSD queue for USB and map it to MT_TXQ_VO since we do not have USB endpoint for PSD. This should make mt76_release_buffered_frames() work by sending released frames via MT_TXQ_VO. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76x02u: add sta_psStanislaw Gruszka

2019-05-01mt76x02u: implement beacon_opsStanislaw Gruszka
Add implementation of beacon_ops for USB and exit function to stop the timer if running when device is removed. Still no actual work on pre tbtt event. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76x02: introduce mt76x02_beacon.cStanislaw Gruszka
Move most of beaconing code into separate file and separate beacon initialization for USB and MMIO as pre TBTT implementation for USB will be different. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-03-19mt76x02u: check chip version on probeStanislaw Gruszka
Since some USB device IDs are duplicated between mt76x0u, mt7601u and mt76x2u device, check chip version on probe and return error if not match the driver. Don't think this is serious issue, probe most likely will fail at some other point for wrong device, but we do not have to configure it if we know is not our device.

2019-02-26mt76usb: use synchronous msg for mcu command responsesStanislaw Gruszka
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.

The series "[PATCH 0/2] mt76x0: initialize per-channel max_power" depends on commit d04ca383860b ("mt76x0u: fix suspend/resume"), so merge wireless-drivers into wireless-drivers-next to get that.
2019-02-07mt76x0u: fix suspend/resumeStanislaw Gruszka
We need to reset MCU and do other initializations on resume otherwise MT7610U device will fail to initialize, what cause system hung due to USB requests timeouts. Patch fixes 4.19 -> 4.20 regression.
