Author: gonzo Date: Mon Jan 23 20:51:29 2017 New Revision: 312671 URL: https://svnweb.freebsd.org/changeset/base/312671 Log: MFC r311911, r311923 r311911: [sdhci] Add ACPI platform support for SDHCI driver - Create ACPI version of SDHCI attach/detach/accessors logic. Some platforms (e.g. BayTrail-based Minnowboard) expose SDHCI devices via ACPI, not PCI - Add sdchi_acpi kernel module Reviewed by: ian, imp Differential Revision: https://reviews.freebsd.org/D9112 r311923: Add acpi_if.h and opt_acpi.h to Makefile to unbreak "make depend" with sys/modules/sdhci_acpi X-MFC with: r311911 Reported by: Jenkins Added: stable/11/sys/dev/sdhci/sdhci_acpi.c - copied unchanged from r311911, head/sys/dev/sdhci/sdhci_acpi.c stable/11/sys/modules/sdhci_acpi/ - copied from r311911, head/sys/modules/sdhci_acpi/ Modified: stable/11/sys/conf/files stable/11/sys/modules/Makefile stable/11/sys/modules/sdhci_acpi/Makefile Directory Properties: stable/11/ (props changed) Modified: stable/11/sys/conf/files ============================================================================== --- stable/11/sys/conf/files Mon Jan 23 19:20:55 2017 (r312670) +++ stable/11/sys/conf/files Mon Jan 23 20:51:29 2017 (r312671) @@ -2557,6 +2557,7 @@ dev/scd/scd.c optional scd isa dev/scd/scd_isa.c optional scd isa dev/sdhci/sdhci.c optional sdhci dev/sdhci/sdhci_if.m optional sdhci +dev/sdhci/sdhci_acpi.c optional sdhci acpi dev/sdhci/sdhci_pci.c optional sdhci pci dev/sf/if_sf.c optional sf pci dev/sge/if_sge.c optional sge pci Copied: stable/11/sys/dev/sdhci/sdhci_acpi.c (from r311911, head/sys/dev/sdhci/sdhci_acpi.c) ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ stable/11/sys/dev/sdhci/sdhci_acpi.c Mon Jan 23 20:51:29 2017 (r312671, copy of r311911, head/sys/dev/sdhci/sdhci_acpi.c) @@ -0,0 +1,370 @@ +/*- + * Copyright (c) 2017 Oleksandr Tymoshenko <gonzo@FreeBSD.org> + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
