6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paul Cercueil paul@crapouillou.net
commit 84228d5e29dbc7a6be51e221000e1d122125826c upstream.
The kernel hangs for a good 12 seconds without any info being printed to dmesg, very early in the boot process, if this regulator is not enabled.
Force-enable it to work around this issue, until we know more about the underlying problem.
