[PATCH 0/4] mt76: mcu api clenups

[Stanislaw Gruszka]

Simplify mcu api and wait for response for mcu commands the same
as vendor driver.

This is on top of:

[PATCH 1/4] mt76: remove mcu_msg_alloc

[Stanislaw Gruszka]

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.

[PATCH 2/4] mt76: remove wait argument from mt76x02_mcu_calibrate

[Stanislaw Gruszka]

We always wait for CMD_CALIBRATION_OP mcu message, but wait argument is used
for do additioanl MT_MCU_COM_REG0 register operations, which are needed
for MMIO devices and we can use mt76_is_mmio() check instead of wait argument.

[PATCH 3/4] mt76: remove wait argument from mt76x02_mcu_function_select

[Stanislaw Gruszka]

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.

With this commit, I hit the WARN_ON on polling the MT_MCU_COM_REG0
register on mt76x0e. It seems to me that this register polling should be
moved out of mt76x02 and into a mt76x2 wrapper function.

I think it would be better to just do mt76x2e check like this:

        bool is_mt76x2e = mt76_is_mmio(dev) && is_mt76x2(dev);

        if (is_mt76x2e)
                mt76_rmw(dev, MT_MCU_COM_REG0, BIT(31), 0);

Then we will not have sparate calibration functions for mt76x2e and
mt76x2u, so code could be easier shared between those.

Thanks
Stanislaw

My suggestion would have been making a wrapper function that checks for
mt76_is_mmio(dev) and gets put into mt76x2-common. What you're proposing
is fine with me as well, I guess it's a matter of preference.

Applied patches 1,3,4.
