v2:

  • Fix the fact that devm_regulator_get_enable_read_voltage() is not available.

ad7768_scale() is dependent on the st->vref voltage. Hence, simplify the
code and get the voltage only during probe (as it should not change at
runtime) with devm_regulator_get_enable_read_voltage()

[nsa: devm_regulator_get_enable_read_voltage() is not available in
2023_R2, so do it by hand to get the voltage during probe]

(cherry picked from commit 44e7ac1)
Similar to

commit 7ebe866 ("iio: adc: adrv9002: fixup tx2 power level")

we need to apply the same fixup even in rx2tx2. The reasoning for not
doing it at the time was that if the channels are tuned together and
have the same SSI delays, it should not be needed. Well...

While at it (and as advised by HW folks), we're now doing the fixup for
all TX channels.

Alright, the Fixes hash does not exist in the 2023_R2 branch as the original faulty commit was also cherry-picked in to the release branch. As this is yet another cherry-pick, I don't think it's that important to change the fixes tag so I would say to ignore the CI failure.
