[ALSA] ASoC: dynamic audio power management (DAPM)
This patch adds Dynamic Audio Power Management (DAPM) to ASoC.
Dynamic Audio Power Management (DAPM) is designed to allow portable and
handheld Linux devices to use the minimum amount of power within the
audio subsystem at all times. It is independent of other kernel PM and
as such, can easily co-exist with the other PM systems.
DAPM is also completely transparent to all user space applications as
all power switching is done within the ASoC core. No code changes or
recompiling are required for user space applications. DAPM makes power
switching decisions based upon any audio stream (capture/playback)
activity and audio mixer settings within the device.
DAPM spans the whole machine. It covers power control within the entire
audio subsystem, this includes internal codec power blocks and machine
level power systems.
There are 4 power domains within DAPM:-
1. Codec domain - VREF, VMID (core codec and audio power)
Usually controlled at codec probe/remove and suspend/resume, although
can be set at stream time if power is not needed for sidetone, etc.
2. Platform/Machine domain - physically connected inputs and outputs
Is platform/machine and user action specific, is configured by the
machine driver and responds to asynchronous events e.g when HP are
inserted
3. Path domain - audio subsystem signal paths
Automatically set when mixer and mux settings are changed by the user.
e.g. alsamixer, amixer.
4. Stream domain - DAC's and ADC's.
Enabled and disabled when stream playback/capture is started and stopped
respectively. e.g. aplay, arecord.
All DAPM power switching decisions are made automatically by consulting
an audio routing map of the whole machine. This map is specific to each
machine and consists of the interconnections between every audio
component (including internal codec components).

[ALSA] ASoC: core code
This patch is the core of ASoC functionality.
The ASoC core is designed to provide the following features :-
o Codec independence. Allows reuse of codec drivers on other platforms
and machines.
o Platform driver code reuse. Reuse of platform specific audio DMA and
DAI drivers on different machines.
o Easy I2S/PCM digital audio interface configuration between codec and
SoC. Each SoC interface and codec registers their audio interface
capabilities with the core at initialisation. The capabilities are
subsequently matched and configured at run time for best power and
performance when the application hw params are known.
o Machine specific controls/operations: Allow machines to add controls
and operations to the audio subsystem. e.g. volume control for speaker
amp.
To achieve all this, ASoC splits an embedded audio system into 3
components :-
1. Codec driver: The codec driver is platform independent and contains
audio controls, audio interface capabilities, codec dapm and codec IO
functions.
2. Platform driver: The platform driver contains the audio dma engine
and audio interface drivers (e.g. I2S, AC97, PCM) for that platform.
3. Machine driver: The machine driver handles any machine specific
controls and audio events. i.e. turning on an amp at start of playback.

We need to be able to get from an irq number to a struct msi_desc.
The msi_desc array in msi.c had several short comings the big one was
that it could not be used outside of msi.c. Using irq_data in struct
irq_desc almost worked except on some architectures irq_data needs to
be used for something else.
So this patch adds a msi_desc pointer to irq_desc, adds the appropriate
wrappers and changes all of the msi code to use them.

With the removal of msi_lookup_irq all of the functions using msi_lock
operated on a single device and none of them could reasonably be

Since what little synchronization that needs to happen needs to happen

such is useless and just complicates the code.

The function msi_lookup_irq was horrible. As a side effect of running
it changed dev->irq, and then the callers would need to change it
back. In addition it does a global scan through all of the irqs,
which seems to be the sole justification of the msi_lock.
To remove the neede for msi_lookup_irq I added first_msi_irq to struct
pci_dev. Then depending on the context I replaced msi_lookup_irq with
dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled.
msi_enabled and msix_enabled were already present in pci_dev for other

MSI: Combine pci_(save|restore)_msi/msix_state
The PCI save/restore code doesn't need to care about MSI vs MSI-X, all
it really wants is to say "save/restore all MSI(-X) info for this device".
This is borne out in the code, we call the MSI and MSI-X save routines
side by side, and similarly with the restore routines.
So combine the MSI/MSI-X routines into pci_save_msi_state() and
pci_restore_msi_state(). It is up to those routines to decide what state
needs to be saved.

MSI: Replace pci_msi_quirk with calls to pci_no_msi()
I don't see any reason why we need pci_msi_quirk, quirk code can just
call pci_no_msi() instead.
Remove the check of pci_msi_quirk in msi_init(). This is safe as all
calls to msi_init() are protected by calls to pci_msi_supported(),
which checks pci_msi_enable, which is disabled by pci_no_msi().
The pci_disable_msi routines didn't check pci_msi_quirk, only
pci_msi_enable, but as far as I can see that was a bug not a feature.

PCI: cleanup MSI code
Cleanup MSI code as follows:
- fix some types
- fix strange local variable definition
- delete unnecessary blank line
- add comment to #endif which is far from corresponding #ifdef

PCI: Speed up the Intel SMBus unhiding quirk
Speed up the Intel SMBus PCI quirk by avoiding tests which can only
fail. This also makes the compiled code significantly smaller when
using gcc 3.2/3.4. gcc 4.x appears to optimize the code by itself so
this change doesn't make a difference there.

PCI Quirk: 1k I/O space IOBL_ADR fix on P64H2
There's an existing quirk for the kernel to use 1k IO space granularity
on the Intel P64H2. It turns out however that pci_setup_bridge() in
drivers/pci/setup-bus.c reads in the IO base and limit address register
masks it off to the nearest 4k, and writes it back. This causes the
kernel to be on 1k boundaries and the hardware to be 4k aligned. The
patch below fixes the problem.

The CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODE config option is not
needed because polling mechanism for shpc hotplug events can be
enabled through module option 'shpchp_poll_mode'. This patch removes
CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODE.
