ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs
This patch series covers both ASoC and extcon subsystems and fixes an interaction between the HPDET function and the headphone outputs - we really shouldn't run HPDET while the headphone is active. The first patch is a refactoring to make the extcon side easier. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJRUcMYAAoJELSic+t+oim9PkAP/RQWC98LrD3kQgVk22MIDdyk P7dr37AePy+nMHP/sp3XIVyeD6pwuRWrlf31jAgMsXSb/+8ymJ3oO3t6aPUa9V9+ KsxxoSUW+/ZO+88aK4r/w/Y45XMqMXsoEwllIxZoEpHXhDIxYFyF8wloPBXLzzbw AALowigrNbeYuijr5R1oV+kUOcT8DpzbamoK0jSbpdBdoPEP3ypD/yJTdi/RSyu/ ELRNZFy4jUw2B3HVOB1YxUeCPpPA63u1oTypFgD7XrQX5v4MDuWyCv5bbBd7KhBk vbK/PHti5CMvi5RbA2EHbkI+n/Lb1qfnxIggN5BaSOQ1tlqrHnMlHYoSE/Sjterh TDGyYDNrWU1Wve2NTDJEd8oECPwm+8ABBnRYgwtnth/4D/EFkT+6Pv8FuIlYg1ku Tj/jwS2q/q26WfssDOph/GfUXtaagMALY99yy/HXM9RPYztOnUyvJIXLzKUUdapT KluChggzbj5ytsSy3L808BkgDxYTwHxva4q+n0ST4hDIeqe95HyE8gZA8jrYOf7T oA4tsBL3i0YGkPoPkVhMY9qeV0AOwDVlZioGP9Qcs8EI/Z9Bri8NZ4iW8VWkNoTt QG7EyuJy90VI/XvGgpITXKXxWQStMZG4+df6pXcn1h47K6ujtDyK/PBBt3t0OPCp WihSDHwuFQPSDWYULbZQ =gc7f -----END PGP SIGNATURE----- Merge tag 'arizona-extcon-asoc' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc into asoc-arizona ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs This patch series covers both ASoC and extcon subsystems and fixes an interaction between the HPDET function and the headphone outputs - we really shouldn't run HPDET while the headphone is active.

Introduction

Currently the ALPS touchpad driver supports five protocol versions in use by
|
||||
ALPS touchpads, called versions 1, 2, 3, 4 and 5.
|
||||
|
||||
Currently the ALPS touchpad driver supports four protocol versions in use by
|
||||
ALPS touchpads, called versions 1, 2, 3, and 4. Information about the various
|
||||
protocol versions is contained in the following sections.
|
||||
Since roughly mid-2010 several new ALPS touchpads have been released and
|
||||
integrated into a variety of laptops and netbooks. These new touchpads
|
||||
have enough behavior differences that the alps_model_data definition
|
||||
table, describing the properties of the different versions, is no longer
|
||||
adequate. The design choices were to re-define the alps_model_data
|
||||
table, with the risk of regression testing existing devices, or isolate
|
||||
the new devices outside of the alps_model_data table. The latter design
|
||||
choice was made. The new touchpad signatures are named: "Rushmore",
|
||||
"Pinnacle", and "Dolphin", which you will see in the alps.c code.
|
||||
For the purposes of this document, this group of ALPS touchpads will
|
||||
generically be called "new ALPS touchpads".
|
||||
|
||||
We experimented with probing the ACPI interface _HID (Hardware ID)/_CID
|
||||
(Compatibility ID) definition as a way to uniquely identify the
|
||||
different ALPS variants but there did not appear to be a 1:1 mapping.
|
||||
In fact, it appeared to be an m:n mapping between the _HID and actual
|
||||
hardware type.

With protocol versions 3 and 4, the E7 report model signature is always

3.3 Multiqueue tuntap interface:
|

|
||||
From version 3.8, Linux supports multiqueue tuntap which can uses multiple
|
||||
file descriptors (queues) to parallelize packets sending or receiving. The
|
||||
device allocation is the same as before, and if user wants to create multiple
|
||||
queues, TUNSETIFF with the same device name must be called many times with
|
||||
IFF_MULTI_QUEUE flag.
|
||||
|
||||
char *dev should be the name of the device, queues is the number of queues to
|
||||
be created, fds is used to store and return the file descriptors (queues)
|
||||
created to the caller. Each file descriptor were served as the interface of a
|
||||
queue which could be accessed by userspace.

1.1 What is an Operating Performance Point (OPP)?
|
||||
|
||||
Complex SoCs of today consists of a multiple sub-modules working in conjunction.
|
||||
In an operational system executing varied use cases, not all modules in the SoC
|
||||
need to function at their highest performing frequency all the time. To
|
||||
facilitate this, sub-modules in a SoC are grouped into domains, allowing some
|
||||
domains to run at lower voltage and frequency while other domains are loaded
|
||||
more. The set of discrete tuples consisting of frequency and voltage pairs that
|
||||
domains to run at lower voltage and frequency while other domains run at
|
||||
voltage/frequency pairs that are higher.
|
||||
|
||||
The set of discrete tuples consisting of frequency and voltage pairs that
|
||||
the device will support per domain are called Operating Performance Points or
|
||||
OPPs.
|
||||
|
||||
As an example:
|
||||
Let us consider an MPU device which supports the following:
|
||||
{300MHz at minimum voltage of 1V}, {800MHz at minimum voltage of 1.2V},
|
||||
{1GHz at minimum voltage of 1.3V}
|
||||
|
||||
We can represent these as three OPPs as the following {Hz, uV} tuples:
|
||||
{300000000, 1000000}
|
||||
{800000000, 1200000}
|
||||
{1000000000, 1300000}
|
||||
|
||||
1.2 Operating Performance Points Library
|
||||
|
||||
OPP library provides a set of helper functions to organize and query the OPP
|
||||
information. The library is located in drivers/base/power/opp.c and the header
|

is located in include/linux/opp.h. OPP library can be enabled by enabling
