* mt76: mt76x02: remove check in mt76x02_mcu_msg_sendLorenzo Bianconi2020-05-281-1/+1
| | | | | | | | mt76x02_mcu_msg_send is run just by mmio code so get rid of mt76_is_mmio() check Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
* mt76: add headroom and tailroom to mt76_mcu_ops data structureLorenzo Bianconi2020-05-121-1/+1
| | | | | | | | | Introduce headroom and tailroom to mt76_mcu_ops data structure in order to unify the routine used for mcu message allocation. This is a preliminary patch to add mt7663u support Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
* mt76: mt76x02: fix handling MCU timeouts during hw restartFelix Fietkau2020-05-121-0/+3
| | | | | | | | | | | | If a MCU timeout occurs before a hw restart completes, another hw restart is scheduled, and the station state gets corrupted. To speed up dealing with that, do not issue any MCU commands after the first timeout, and defer handling timeouts until the reset has completed. Also ignore errors in MCU commands during start/config to avoid making user space fail on this condition. If it happens, another restart is scheduled quickly, and that usually recovers the hardware properly. Signed-off-by: Felix Fietkau <nbd@nbd.name>
* mt76: Introduce mt76_mcu data structureLorenzo Bianconi2020-02-141-5/+5
| | | | | | | | | | | 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>
* mt76: use mt76_dev in mt76_is_{mmio,usb}Lorenzo Bianconi2019-11-201-1/+1
| | | | | | | | | Convert mt76_is_mmio and mt76_is_usb to rely on mt76_dev instead of mt76x02_dev since this is a property not strictly related to hw chipset and it will be more reusable Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
* mt76: switch to SPDX tag instead of verbose boilerplate textRyder Lee2019-09-051-12/+1
| | | | | | | | | No functional change intended. Add SPDX identifiers to all remaining files in /mt76. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
* mt76: mt76x02: fix some checkpatch warningsRyder Lee2019-09-051-6/+7
| | | | | | | | | | | | | | | This fixes the following checkpatch warnings: ERROR: code indent should use tabs where possible CHECK: Alignment should match open parenthesis CHECK: No space is necessary after a cast CHECK: Please don't use multiple blank lines CHECK: Avoid precedence issues in macro WARNING: Statements should start on a tabstop WARNING: Unnecessary space before function pointer arguments Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
* mt76: mt76x02: issue watchdog reset on MCU request timeoutFelix Fietkau2019-02-261-0/+1
| | | | | | | MCU request timeout usually indicates that the device is no longer responsive, and it usually does not recover without a reset Signed-off-by: Felix Fietkau <nbd@nbd.name>
* mt76: move mt76_dma_tx_queue_skb_raw in mt76-core moduleLorenzo Bianconi2019-02-181-32/+8
| | | | | | | | | | Move mt76_dma_tx_queue_skb_raw routine in dma.c and add the corresponding entry in mt76_queue_ops data structure. mt76_dma_tx_queue_skb_raw will be reused adding support for mt7603 driver Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

* mt76: remove wait argument from mt76x02_mcu_calibrateStanislaw Gruszka2018-11-301-4/+4
| | | | | | | | | We always wait for CMD_CALIBRATION_OP mcu message, but wait argument is used for do additional MT_MCU_COM_REG0 register operations, which are needed for mt76x2e devices and we can use appropriate check instead of wait argument.

* mt76: remove wait argument from mt76x02_mcu_set_radio_stateStanislaw Gruszka2018-11-301-4/+2
| | | | | | | | | | Remove wait argument from mt76x02_mcu_set_radio_state and newer wait for response when sending CMD_POWER_SAVING_OP mcu command. Note this change behaviour for PCIe devices, but the change is in align with vendor driver. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
* mt76: remove wait argument from mt76x02_mcu_function_selectStanislaw Gruszka2018-11-301-5/+7
| | | | | | | | | | | | | Remove wait argument from mt76x02_mcu_function_select and wait for response when function is not Q_SELECT, what is the same behaviour like in vendor driver. Note this change behaviour for PCIe devices for Q_SELECT function form wait to no-wait, and for mt76x0u BW_SETTING from no-wait to wait. But the change is in align with vendor driver.

* mt76: remove mcu_msg_allocStanislaw Gruszka2018-11-301-14/+12
| | | | | | | | | | | | We almost always use patter like this: skb = mt76_mcu_msg_alloc(dev, &msg, sizeof(msg)); return mt76_mcu_send_msg(dev, skb, CMD_FUN_SET_OP, wait_resp); This is not needed, we can allocate skb in mcu_send_msg routine.
