From a355d67817eccdbe869020f8f5a3123f21f8106f Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 12 Feb 2014 13:42:50 +0000 Subject: ASoC: Intel: Add a mfld prefix to Intel SST drivers. Resent with correct email for Mark. In order to differentiate the different Intel SST audio core drivers we need to rename the current drivers with a mfld prefix. This also includes renaming in the Makefile and Kconfig Acked-by: Vinod Koul Signed-off-by: Liam Girdwood Signed-off-by: Mark Brown --- sound/soc/intel/Kconfig | 4 +- sound/soc/intel/Makefile | 4 +- sound/soc/intel/sst-mfld-dsp.h | 134 +++++++ sound/soc/intel/sst-mfld-platform.c | 725 ++++++++++++++++++++++++++++++++++++ sound/soc/intel/sst-mfld-platform.h | 153 ++++++++ sound/soc/intel/sst_dsp.h | 134 ------- sound/soc/intel/sst_platform.c | 725 ------------------------------------ sound/soc/intel/sst_platform.h | 153 -------- 8 files changed, 1016 insertions(+), 1016 deletions(-) create mode 100644 sound/soc/intel/sst-mfld-dsp.h create mode 100644 sound/soc/intel/sst-mfld-platform.c create mode 100644 sound/soc/intel/sst-mfld-platform.h delete mode 100644 sound/soc/intel/sst_dsp.h delete mode 100644 sound/soc/intel/sst_platform.c delete mode 100644 sound/soc/intel/sst_platform.h diff --git a/sound/soc/intel/Kconfig b/sound/soc/intel/Kconfig index 61c10bf503d2..4d9d0a546cb1 100644 --- a/sound/soc/intel/Kconfig +++ b/sound/soc/intel/Kconfig @@ -2,12 +2,12 @@ config SND_MFLD_MACHINE tristate "SOC Machine Audio driver for Intel Medfield MID platform" depends on INTEL_SCU_IPC select SND_SOC_SN95031 - select SND_SST_PLATFORM + select SND_SST_MFLD_PLATFORM help This adds support for ASoC machine driver for Intel(R) MID Medfield platform used as alsa device in audio substem in Intel(R) MID devices Say Y if you have such a device If unsure select "N". -config SND_SST_PLATFORM +config SND_SST_MFLD_PLATFORM tristate diff --git a/sound/soc/intel/Makefile b/sound/soc/intel/Makefile index 639883339465..eb899fc90d92 100644 --- a/sound/soc/intel/Makefile +++ b/sound/soc/intel/Makefile @@ -1,5 +1,5 @@ -snd-soc-sst-platform-objs := sst_platform.o +snd-soc-sst-mfld-platform-objs := sst-mfld-platform.o snd-soc-mfld-machine-objs := mfld_machine.o -obj-$(CONFIG_SND_SST_PLATFORM) += snd-soc-sst-platform.o +obj-$(CONFIG_SND_SST_MFLD_PLATFORM) += snd-soc-sst-mfld-platform.o obj-$(CONFIG_SND_MFLD_MACHINE) += snd-soc-mfld-machine.o diff --git a/sound/soc/intel/sst-mfld-dsp.h b/sound/soc/intel/sst-mfld-dsp.h new file mode 100644 index 000000000000..3b63edc04b7f --- /dev/null +++ b/sound/soc/intel/sst-mfld-dsp.h @@ -0,0 +1,134 @@ +#ifndef __SST_MFLD_DSP_H__ +#define __SST_MFLD_DSP_H__ +/* + * sst_mfld_dsp.h - Intel SST Driver for audio engine + * + * Copyright (C) 2008-12 Intel Corporation + * Authors: Vinod Koul + * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; version 2 of the License. + * + * This program is distributed in the hope that it will be useful, but + * WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Add support for Intel Smart Sound Technology (SST) audio DSPs. This driver provides the low level IO, reset, boot and IRQ management for Intel audio DSPs. These files make up the low level part of the SST audio driver stack and will be used by many Intel SST cores like Haswell, Broadwell and Baytrail. SST DSPs expose a memory mapped region (shim) for config and control. The shim layout is mostly shared without much modification across cores and this driver provides a uniform API to access the shim and to enable basic shim functions. It also provides functionality to abstract some shim functions for cores with different shim features.

It makes sense to avoid duplication of the driver enumeration logic and concentrate the functionality into a single ACPI SST enumeration file. Idea of this loader is to parse data we get from ACPI and to be able to load needed other SST drivers and ASoC machine driver runtime based on single ACPI ID what BIOS gives to us.

Provide services for Intel SST drivers to load SST modular firmware. SST Firmware can be made up of several modules. These modules can exist within any of the compatible SST memory blocks. Provide a generic memory block and firmware module manager that can be used with any SST firmware and core.

However plain request_firmware doesn't work in driver probe paths if userspace is not ready to handle it. For instance when drivers are built-in. Implementing asynchronous firmware request in SST platform driver initialization complicates code needlessly since it anyway will fail if firmware is missing. This is more simple to handle by requesting firmware asynchronously in sst_acpi_probe() and register SST platform only after firmware is loaded.

It was known restriction to be improved incrementally. This patch is now changing this that SST ACPI ID refers purely to platform specific data which refers to machine drivers on this platform, not vice versa. Matching machine driver is found by looking at ACPI ID which would best match with the driver. Typically this would be the ACPI ID of audio codec but is not tied to it. This patch also changes that DSP firmware name is machine not platform specific.
