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 probing and firmware loading on MT7622Felix Fietkau
MT7622 does not have a CR4 microcontroller, so it only uses its own N9 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>
2020-02-14mt76: mt7615: add eeprom support for MT7622Felix Fietkau

2020-02-14mt76: mt7615: store N9 firmware version instead of CR4Felix Fietkau
CR4 is used very little, N9 is the main firmware that the driver interacts with Signed-off-by: Felix Fietkau <nbd@nbd.name>

Preparation for adding MT7622 support Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: fix endianness in mt7615_mcu_set_eepromRyder Lee
The field 'u16 len' should be __le16. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: initialize radar specs from host driverLorenzo Bianconi
Introduce dfs radar pattern specs in mt7615 driver in order to make dfs debugging easier. Radar pulse/pattern thresholds are taken from vendor SDK. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: rework set_channel functionRyder Lee
No need to send both MCU_EXT_CMD_SET_RX_PATH and MCU_EXT_CMD_CHANNEL_SWITCH together to MCU. Split them out by passing the proper command in the corresponding flow. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: increase MCU command timeoutFelix Fietkau
MCU_EXT_CMD_EFUSE_BUFFER_MODE needs more time on initialization, and with only 10 seconds it sometimes runs into timeouts. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: report firmware version using ethtoolLorenzo Bianconi

2020-02-14mt76: mt7615: rework chainmask handlingFelix Fietkau
Move chainmask to struct mt7615_phy and instead of needlessly making the format similar to values for older chips, make it refer to the actual chain bits used for the rx/tx path. This is important for multiple wiphy support, where for a secondary phy, antenna_mask will start at 0, and chainmask will start at the chain offset (bit 2) Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: add multiple wiphy support to the dfs support codeFelix Fietkau
There are two DFS detectors on the chip. When using 160 MHz channel bandwidth (not supported in dual-wiphy mode), both are used. Otherwise, one detector is used per wiphy. Rework the code to start/stop them separately per phy and to indicate the radar event on the right phy based on the detector index Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: add dual-phy support for mac80211 opsFelix Fietkau

2019-09-05mt76: mt7615: introduce mt7615_mcu_send_ram_firmware routineLorenzo Bianconi

2019-09-05mt76: mt7615: clean up FWDL TXQ during/after firmware uploadFelix Fietkau
Since we don't clean that tx queue from the tx tasklet, we need to do it after the firmware upload is done. This patch also adds a cleanup step during the upload, to help reclaim memory faster. Fixes unprocessed queued frames eating up memory long after the firmware upload has already completed Signed-off-by: Felix Fietkau <nbd@nbd.name>
