2022-02-03mt76: sdio: disable interrupt in mt76s_sdio_irqSean Wang1-0/+1
It is unnecessary to keep the interrupt enabled in mt76s_sdio_irq because the driver is already aware of the interrupt, schedules the mt76s_txrx_worker to handle the corresponding actions, and eventually, the interrupt would be enabled again when mt76s_txrx_worker finishes its work. So we can safely disable the interrupt in mt76s_sdio_irq as soon as possible to increase the CPU productivity by dropping the redundant interrupt triggers. Note that sdio lock acquired/released would be handled in sdio_irq_work at mmc driver so we don't take care in mt76s_sdio_irq at function driver.

2022-02-03mt76: mt7921: fix crash when startup fails.Ben Greear1-0/+1
If the nic fails to start, it is possible that the reset_work has already been scheduled. Ensure the work item is canceled so we do not have use-after-free crash in case cleanup is called before the work item is executed. This fixes crash on my x86_64 apu2 when mt7921k radio fails to work. Radio still fails, but OS does not crash.

2022-02-03mt76: mt7921e: fix possible probe failure after rebootSean Wang4-123/+139
It doesn't guarantee the mt7921e gets started with ASPM L0 after each machine reboot on every platform. If mt7921e gets started with not ASPM L0, it would be possible that the driver encounters time to time failure in mt7921_pci_probe, like a weird chip identifier is read [ 215.514503] mt7921e 0000:05:00.0: ASIC revision: feed0000 [ 216.604741] mt7921e: probe of 0000:05:00.0 failed with error -110 or failing to init hardware because the driver is not allowed to access the register until the device is in ASPM L0 state. So, we call __mt7921e_mcu_drv_pmctrl in early mt7921_pci_probe to force the device to bring back to the L0 state for we can safely access registers in any case. In the patch, we move all functions from dma.c to pci.c and register mt76 bus operation earilier, that is the __mt7921e_mcu_drv_pmctrl depends on.

2022-02-03mt76: mt7921s: fix mt7921s_mcu_[fw|drv]_pmctrlLeon Yen2-0/+40
According to the firmware behavior (even the oldest one in linux-firmware) If the firmware is downloaded, MT7921S must rely on the additional mailbox mechanism that resides in firmware to check if the device is the right state for mt7921s_mcu_[fw|drv]_pmctrl. Otherwise, we still apply the old way for that. That is a necessary patch before we enable runtime pm for mt7921s as default.
