Thank you very much for making requested changes and your patience. I
think we just need a few finishing touches and we can commit this
driver.

I wonder if we really need to pass "response" as a parameter here.

Let's call it "int i" - the standard loop variable.

I do not think we need "msg" anymore.

I think I already asked this, but I do not recall the answer: can we
supply commands with bits pre-reversed (i.e. specify PSX_CMD_POLL as
0x80, 0x42, 0x00, ... and PSX_CMD_ENTER_CFG as 0x80, 0xc2, 0x00, 0x80,
0x00, ... and so on, and reverse arguments when you supply them? See
more in psxpad_setenablemotor().

Just return directly here:

We only use returned data when we poll the device. Maybe we should do
this bit-reversing outsize of psxpad_command()?

psxpad_control_motor() and there is really no need for "const" on scalar
arguments.

Assuming that the commands are "pre-revrsed":
memcpy(pad->sendbuf, PSX_CMD_ENTER_CFG, sizeof(PSX_CMD_ENTER_CFG);
err = psxpad_command(pad, sizeof(PSX_CMD_ENTER_CFG));
if (err) {
dev_err(&pad->spi->dev,
"%s: failed to enter config mode: %d\n",
__func__, err);
return err;
}
memcpy(pad->sendbuf, PSX_CMD_ENABLE_MOTOR, sizeof(PSX_CMD_ENABLE_MOTOR);
pad->sendbuf[3] = motor1enable ? 0x00 : 0xff;
pad->sendbuf[4] = motor2enable ? 0x80 : 0xff;
err = psxpad_command(pad, sizeof(PSX_CMD_ENABLE_MOTOR));
if (err) {
dev_err(&pad->spi->dev,
"%s: ENABLE_MOTOR command failed: %d\n",
__func__, err);
return err;
}
...

So we need to control motors both while polling and explicitly at end of
poll?

Please use pad->spi->dev in error messages, so errors are associated
with a physical device and not abstract one (inputNNN).

Please use BIT() macro; there is also no need to convert to true/false
as input_report_key also does it.
input_report_key(pad->idev, BTN_DPAD_UP,
pad->response[3] & BIT(4));
input_report_key(pad->idev, BTN_DPAD_DOWN,
pad->response[3] & BIT(7));
and so on.

platform_data usually reserved for platform (board) code, not driver
data.
struct input_polled_dev *pdev = input_get_drvdata(input);

No need for "psxpad-spi: " prefix - dev_err adds driver name to error
messages.

Just
return -ENOMEM;
devm will take care of freeing "pad" memory. That is is point of devm_*
