Using the kernels shipped with Debian, since linux 4.18 the
beagleboard-x15 no longer recognizes microSD or eMMC.
Reverting to the earlier 4.17.x kernels "fixes" it, but Debian buster
will be released with 4.19.x, and it would be a shame for it to not work
out of the box.
the omap_hsmmc module loads fine, but doesn't detect anything, and
doesn't leave any obvious error or warnings in the logs.
Are there any changes to the needed regulators or some soft module
dependency in newer kernel versions that might need to be updated in the
kernel config? Other ideas?
