The branch main has been updated by khng: URL: https://cgit.FreeBSD.org/src/commit/?id=53b5393319dd7b54d63e8bf9aa82e48618552ecb commit 53b5393319dd7b54d63e8bf9aa82e48618552ecb Author: Ka Ho Ng <khng@FreeBSD.org> AuthorDate: 2024-04-12 16:56:42 +0000 Commit: Ka Ho Ng <khng@FreeBSD.org> CommitDate: 2024-04-12 17:04:23 +0000 uart_snps: Register a device xref for UARTs This is useful for other drivers to be able to find the UART (such as the case of UARTs where hardware flow control lines are handled by another device.)
