2020-07-21mt76: mt7615: sdio code must access rate/key regs in preocess contextLorenzo Bianconi
As usb, sdio relies on mt76 workqueue to configure tx rate or upload keys to the hw. This is a preliminary patch to add SDIO support to mt76 driver Co-developed-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-07-21mt76: mt7663u: sync probe sampling with rate configurationLorenzo Bianconi
On usb device rate configuration for sampling is performed relying on a workqueue since it is not possible to access the device in the interrupt context.

2020-07-21mt76: mt7615: schedule tx tasklet and sta poll on mac tx freeFelix Fietkau
Unlike on earlier chips, DMA completion on MT7615 does not imply actually having sent out any packets. Since AQL will prevent filling the hardware queues and will only allow more packets to be passed to the driver after tx completion, it makes much more sense to schedule the tx tasklet there. This is also needed for scheduling tx in testmode support Signed-off-by: Felix Fietkau <nbd@nbd.name>
