Hi Ulf
We've tested your change. It seems to be working fine. We mainly focused on
testing stability and that the performance wasn't decreased. All tests
passed.
As far as performance improvement: it wasn't affected because of BKOPs
feature.
Please let me know if there is any specific test

When switching SD and SDIO cards from 3.3V to 1.8V signal levels, the
clock should be gated for 5 ms during the step. After enabling the
clock, the host should wait for at least 1 ms before checking for
failure. Failure by the card to switch is indicated by dat[0:3] being
pulled low. The host
