* qtnfmac: send EAPOL frames via control pathSergey Matyukevich2019-11-141-1/+0
| | | | | | | | | | | | Send EAPOL frames via control path so they can be treated in a different way rather than normal data frames. In this case EAPOLs are sent with higher priority and with disabled aggregation and encryption. Besides, all devices benefit from sending EAPOL frames via high priority path, so move the functionality from chip specific to common code.

* qtnfmac: modify Rx descriptors queue setupSergey Matyukevich2019-11-141-3/+2
| | | | | | | | | Rx descriptors queue length is hardware specific. Current common default value is no more than an accident. So move Rx descriptor queue setup to platform PCIe backend in the same way as it is already done for Tx.

* qtnfmac: fix debugfs support for multiple cardsSergey Matyukevich2019-11-141-1/+5
| | | | | | | | | Fix merge artifact for commit 0b68fe10b8e8 ("qtnfmac: modify debugfs to support multiple cards") and finally add debugfs support for multiple qtnfmac wireless cards.

* qtnfmac_pcie: Use dev_get_drvdataChuhong Yuan2019-08-061-2/+2
| | | | | | | | Instead of using to_pci_dev + pci_get_drvdata, use dev_get_drvdata to make code simpler. Signed-off-by: Chuhong Yuan <hslester96@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* qtnfmac: send EAPOL frames via control pathIgor Mitsyanko2019-04-041-0/+1
| | | | | | | | Use control path to send EAPOL frames to make sure they are sent with higher priority with aggregation disabled. Signed-off-by: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* qtnfmac: simplify firmware state trackingSergey Matyukevich2019-04-041-6/+4
| | | | | | | | | | | | | This patch streamlines firmware state tracking. In particular, state QTNF_FW_STATE_FW_DNLD_DONE is removed, states QTNF_FW_STATE_RESET and QTNF_FW_STATE_DETACHED are merged into a single state. Besides, new state QTNF_FW_STATE_RUNNING is introduced to distinguish between the following two cases: - firmware load succeeded, firmware init process is ongoing - firmware init succeeded, firmware is fully functional Signed-off-by: Sergey Matyukevich <sergey.matyukevich.os@quantenna.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* qtnfmac: fix core attach error path in pcie backendSergey Matyukevich2019-04-041-17/+8
| | | | | | | | | | | Report that firmware is up and running only for successful firmware download. Simplify qtnf_pcie_fw_boot_done: modify error path so that no need to pass firmware dowload result to this function. Finally, do not create debugfs entries if firmware download succeeded, but core attach failed.

* qtnfmac: add support for Topaz chipsetsSergey Matyukevich2018-11-061-1/+4
| | | | | | | | | | | | | | | | | | This patch adds support for QSR1000/QSR2000 family of chipsets to qtnfmac_pcie platform driver. QSR1000/QSR2000 (aka Topaz) is a family of 80MHz, 11ac Wave2, 4x4/2x4/2x2 chips, including single and dual band devices. Depending on specific chip model and firmware in use, either STA or both STA and AP modes are supported. Patch adds Topaz support to qtnfmac_pcie driver. Proper platform bus will be selected on probing based on chip ID.

* qtnfmac_pcie: use single PCIe driver for all platformsIgor Mitsyanko2018-11-061-84/+195
| | | | | | | | Single PCIe driver can identify hardware type by reading CHIP ID at probe time and invoking a correct initialization sequence. Signed-off-by: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* qtnfmac: drop redundant data copy in control pathSergey Matyukevich2018-10-051-2/+3
| | | | | | | | | | | Command responses and events from the firmware are copied twice in control path: at first in shm core (qtnf_shm_handle_new_data) and then in pcie bus drivers (qtnf_pcie_control_rx_callback). There is no need to copy this data twice, it can be done only once in rx callbacks.

* qtnfmac: wait for FW load work to finish at PCIe removeIgor Mitsyanko2018-10-011-3/+1
| | | | | | | | | Waiting for "completion" to be set in FW load thread can not be used in case PCIe remove is called before FW load work was scheduled. Just wait for work completion instead to avoid problems. Signed-off-by: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
