2020-02-14mt76: mt7615: simplify mcu_set_bmc flowRyder Lee
Move set_bmc_wtbl into sta_rec function to simplify flow. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: add support for testing hardware resetFelix Fietkau
Send an undersized corrupt packet to the DMA queue, which causes the firmware to issue a full chip reset Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: implement hardware reset supportFelix Fietkau
When the firmware detects a problem, it needs the host to stop/reset DMA and resume it again when the hardware state has been reset. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: report firmware log event messagesFelix Fietkau
Useful for debugging firmware issues. Can be turned on via the "fw_debug" debugfs file Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: fix and rework tx power handlingFelix Fietkau
Setting the tx power by manipulating EEPROM may in some cases not be enough, since it only covers the base target power and not per-rate offsets. In other cases, it could limit tx power of rates too much, possibly reducing throughput or range. Use firmware support for applying per-rate limit and power offsets for different values of Nss. Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-02-14mt76: mt7615: implement DMA support for MT7622Felix Fietkau
MT7622 does not have the CR4 microcontroller sitting in the data path. Because of that, it uses the chip's native tx descriptor format instead of something parsed and converted by the firmware. Co-developed-by: Shayne Chen <shayne.chen@mediatek.com> Co-developed-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org>
2020-02-14mt76: mt7615: implement probing and firmware loading on MT7622Felix Fietkau

2020-02-14mt76: mt7615: fix MT_INT_TX_DONE_ALL definition for MT7622Felix Fietkau

2020-02-14mt76: mt7603: increase dma mcu rx ring sizeFelix Fietkau
The ring is used for looping back tx powersave filtered frames, so it could use some more room, in case more than one aggregate was queued Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: dma: do not write cpu_idx on rx queue reset until after refillFelix Fietkau
