The branch stable/13 has been updated by manu: URL: https://cgit.FreeBSD.org/src/commit/?id=ac90d8077136a3bb573824ebad0332e6e1a2f187 commit ac90d8077136a3bb573824ebad0332e6e1a2f187 Author: Emmanuel Vadot <manu@FreeBSD.org> AuthorDate: 2021-05-16 12:50:10 +0000 Commit: Emmanuel Vadot <manu@FreeBSD.org> CommitDate: 2021-07-22 17:09:39 +0000 mmc_fdt_helpers: Parse the optional pwrseq element.
