2023-07-26wifi: mt76: mt7921: move runtime-pm pci code in mt792x-libLorenzo Bianconi
Move the following runtime-pm pci routines in mt792x-lib since they are shared between mt7921 and mt7925 chipsets: - __mt7921e_mcu_drv_pmctrl - mt7921e_mcu_drv_pmctrl - mt7921e_mcu_fw_pmctrl Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Deren Wu <deren.wu@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2023-02-03wifi: mt76: mt7921: reduce polling time in pmctrlDeren Wu
Due to the polling tick is 10ms, the wake up flow in the status waiting would cause more 10~20ms than the real HW response time. Reduce tick-interval from 10ms to 1ms to get better network performance, such as ping latency, in low power mode.

2022-09-15wifi: mt76: mt7921: get rid of the false positive resetSean Wang
False positive reset would be possibly triggered by those commands we applied in suspend with HZ MCU timeout, especially it happened when we enabled kernel log in pm core to diagnose how much time we spend in each driver during suspend procedure. So we enlarge the value and align the MCU timeout as other commands we did to reduce the false positive reset.

2022-02-03mt76: mt7921e: fix possible probe failure after rebootSean Wang
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.
