2019-11-20mt76: use mt76_dev in mt76_is_{mmio,usb}Lorenzo Bianconi1-6/+6
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>

2019-06-27mt76: mt76x0: fix RF frontend initialization for external PAFelix Fietkau1-6/+7
When loading EEPROM data from flash, the RF frontend settings need to be initialized from flash data. Without this, the chip loads the wrong values from its internal eFuse ROM. Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-02-26mt76: mt76x02: fix ED/CCA enabling/disablingFelix Fietkau1-5/+1
ED/CCA needs to be disable before stopping the MAC to avoid hangs from tx being blocked. It must only be enabled again after the MAC has been started again. In many places this wasn't done properly, so fix this by always clearing the relevant ED/CCA bits in mt76x2_mac_stop and set it up again after channel change or calibration is done Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76x0: init: introduce mt76x0_init_txpower routineLorenzo Bianconi1-2/+2

The series "[PATCH 0/2] mt76x0: initialize per-channel max_power" depends on commit d04ca383860b ("mt76x0u: fix suspend/resume"), so merge wireless-drivers into wireless-drivers-next to get that.

2018-11-30mt76: remove wait argument from mt76x02_mcu_calibrateStanislaw Gruszka1-8/+6
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.

2018-11-30mt76x02: assure we update gain after scanStanislaw Gruszka1-1/+2
Assure that after we initialize dev->cal.low_gain to -1 this will cause update gain calibration. Otherwise this might or might not happen depending on value of second bit of low_gain and values read from registers in mt76x02_phy_adjust_vga_gain().

2018-11-30mt76x02: run calibration after scanningStanislaw Gruszka1-1/+1
If we are associated and scanning is performed, sw_scan_complete callback is done after we get back to operating channel, so we do not perform queue cal work. Fix this queue cal work from sw_scan_complete(). On mt76x0 we have to restore gain in MT_BBP(AGC, 8) register after scanning, as it was multiple times modified by channel switch code. So queue cal work without any delay to set AGC gain value. Similar like in mt76x2 init AGC gain only when set operating channel and just check before queuing cal work in sw_scan_complete() if initialization was already done.

2018-11-30mt76: remove wait argument from mt76x02_mcu_function_selectStanislaw Gruszka1-1/+1
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.

2018-11-30mt76x0: use band parameter for LC calibrationStanislaw Gruszka1-2/+3
We use always 1 as band parameter for MCU_CAL_LC, this break 2GHz, we should use 0 for this band instead.

2018-11-30mt76x0: do not overwrite other MT_BBP(AGC, 8) fieldsStanislaw Gruszka1-3/+1
MT_BBP(AGC, 8) register has values depend on band in mt76x0_bbp_switch_tab, so we should not overwrite other fields than MT_BBP_AGC_GAIN when setting gain. This can fix performance issues when connecting to 2.4GHz AP.

Plus small MT7630E quirk for MT_CMB_CTRL register which vendor driver dedicated to this chip do. This make MT7630E workable with mt76x0e driver and do not cause any problems on MT7610U for me.

2018-11-30mt76: mt76x0: handle chip specific initval differencesFelix Fietkau1-2/+45
