Hi Bjorn, Abel, Konrad,
Please drop this patch.
I re-tested on Shikra EVK with and without the RF_CLK2 clock described on
the wcn3988-pmu nodes, and Bluetooth comes up in both cases. The
commit message claim that Bluetooth fails to come up without the clock
does not hold, so the patch is not needed for Bluetooth. Thanks to
Abel and Konrad for the reviews.
Sorry for the noise.
