The branch main has been updated by mw: URL: https://cgit.FreeBSD.org/src/commit/?id=6ad816a999171874c36c73d5794d0d25ff8fd311 commit 6ad816a999171874c36c73d5794d0d25ff8fd311 Author: Bartlomiej Grzesik <bag@semihalf.com> AuthorDate: 2021-07-15 15:20:46 +0000 Commit: Marcin Wojtas <mw@FreeBSD.org> CommitDate: 2021-08-17 07:03:45 +0000 sdhci_xenon: remove redundant code in property parsing Remove redundant ofw property parsing in driver code, is already taken care of in mmc_fdt_helpers. Move ofw parsing to attach method.
