Russel and other maintainers prefered that ACPI learned how to create AMBA devices rather than converting/adding platform_device support to AMBA drivers. http://comments.gmane.org/gmane.linux.ports.arm.kernel/431364 1) Adds basic AMBA device probing support to ACPI, it uses a whitelist of device IDs as the number of AMBA devices is limited. Currently the two ids present are those used in QEMU for arm64. 2) Adds the plumbing into ACPI probe sequence. 3) From ACPI pl011 is only defined (SBSA document) to be in SBSA mode which has reduced functionality. There may be a better method to do this that I have overlooked. v4: - A memory leak has been fixed (Vladimir Zapolskiy) - ACPI_COMPANION() -> has_acpi_companion() (Andy Shevchenko) - pr_err() -> dev_err() (Andy Shevchenko) - The call to amba_register_dummy_clk() has been moved to to acpi_amba_init() (Vladimir Zapolskiy) - Return value has been fixed (Vladimir Zapolskiy) v3: https://lkml.kernel.org/g/1450716100-13688-1-git-send-email-aleksey.makarov@linaro.org - Compilation without CONFIG_ARM_AMBA has been fixed v2: https://lkml.kernel.org/g/1450709399-7246-1-git-send-email-aleksey.makarov@linaro.org - A new ACPI scan handler for AMBA devices has been implemented - The order of `if` branches in amba-pl011.c has been changed - A couple of `static`s have been added - The compilation of the acpi_amba.c unit has made conditional - A comment on SBSA UART has been added v1: https://lkml.kernel.org/g/1443609530-21524-1-git-send-email-graeme.gregory@linaro.org Graeme Gregory (3): ACPI: amba bus probing support ACPI: scan add in amba probing serial: amba-pl011: add ACPI support to AMBA probe drivers/acpi/Makefile | 1 + drivers/acpi/acpi_amba.c | 140 ++++++++++++++++++++++++++++++++++++++++ drivers/acpi/internal.h | 5 ++ drivers/acpi/scan.c | 1 + drivers/tty/serial/amba-pl011.c | 37 +++++++---- 5 files changed, 173 insertions(+), 11 deletions(-) create mode 100644 drivers/acpi/acpi_amba.c -- 2.6.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
