2020-03-17mt76: mt7615: introduce mt7615_register_mapLorenzo Bianconi
In order to reuse mt7615 code adding support for mt7663e driver, introduce mt7615e_reg_map since mt7663e and mt7615 rely on a different base registers definitions. Co-developed-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Sean Wang <sean.wang@mediatek.com> Co-developed-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-03-17mt76: mt7615: move more mcu commands in mt7615_mcu_ops data structureLorenzo Bianconi
Move mt7615_mcu_set_beacon_offload, mt7615_mcu_set_dev and mt7615_mcu_set_bss routine in mt7615_mcu_ops data structure. This is a preliminary patch to support mt7663 firmware Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-03-17mt76: mt7615: remove a stray if statementDan Carpenter
This if statement was supposed to be deleted, but it wasn't. It means that we sometimes don't set the sensitivity correctly. Fixes: 2cad515ece8a ("mt76: mt7615: add missing settings for simultaneous dual-band support") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-03-17mt76: mt7615: fix monitor injection of beacon framesFelix Fietkau
When injecting beacon frames via monitor interface, they must not be sent to the beacon hardware queue, because they don't follow normal hardware beacon tx rules. Fix sending them by adding a flag to mt7615_mac_write_txwi that selects the beacon queue for tx, and use it only from mt7615_mcu_set_bcn. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: Introduce mt76_mcu data structureLorenzo Bianconi
Introduce mt76_mcu data structure to contain common fields between mt76u_mcu and mt76e_mcu. Initialize mcu common fields in mt76_alloc_device(). Rely on mt76_mcu in mt76_mcu_rx_event and in mt76_mcu_get_response in order to reuse them in usb code Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: rework rx phy index handlingFelix Fietkau
Overwriting the RMAC_CHFREQ register is not reliable enough, as the firmware could potentially write it again. Since there is no PHY index indication in the rx info, we need to use another way: If both PHYs are using different channels, find the PHY where chfreq matches the register value. The only corner case remaining is when both PHYs are using the same channel. In that case, the per-packet noise value on the primary PHY will have information belonging to the chains of the secondary PHY from the previous received packet of that PHY. The secondary PHY will set noise to 0 for extra chains. 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: 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: add missing settings for simultaneous dual-band supportRyder Lee
MT7615 supports dual-wiphy which means that it can run on 2.4G and 5GHz channels simultaneously, and driver should configure each band. Add missing register settings, and refine band related definitions to avoid duplicate codes. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: measure channel noise and report it via surveyFelix Fietkau

2020-02-14mt76: mt7615: Fix build with older compilersPablo Greco
Some compilers (tested with 4.8.5 from CentOS 7) fail properly process FIELD_GET inside an inline function, which ends up in a BUILD_BUG_ON. Convert inline function to a macro. Fixes commit bf92e7685100 ("mt76: mt7615: add support for per-chain signal strength reporting") Reported in https://lkml.org/lkml/2019/9/21/146 Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Pablo Greco <pgreco@centosproject.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: select the correct tx queue for frames sent to the second phyFelix Fietkau
Beacons and management frames need to explicitly select the alternate tx queues in order to be sent out on the right phy Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7615: add multiple wiphy support to the rx pathFelix Fietkau
Program the RMAC CHFREQ registers to properly indicate the band that the frames are received on. Add some sanity checks to the programmed values, because the firmware programs these registers differently 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: remove useless MT_HW_RDD0/1 enumFelix Fietkau
