soundwire: intel_ace2x: add empty new ops for LunarLake

2023-05-27T10:36:44+00:00

The register map and programming sequences for the ACE2.x IP are
completely different and need to be abstracted with a different set of
callbacks.

This initial patch adds a new file, follow-up patches will add each
required callback.

soundwire: intel: move bus common sequences to different file

2023-03-15T13:54:02+00:00

Now that the bus start/stop/clock_stop sequences use the ops, we can
move them to a different file to reuse them.

Note that we could in theory remove the abstraction for all those
sequences and directly call the functions in intel_auxdevice.c. To
allow for more flexibility and have means to special-case new
platforms, we decided to keep the abstraction. If in time it becomes
clear there is no benefit the abstraction will be simplified.

soundwire: intel: split auxdevice to different file

2022-11-23T14:41:49+00:00

The auxdevice layer is completely generic, it should be split from
intel.c which is only geared to the 'cnl' hw_ops now.

soundwire: Intel: introduce DMI quirks for HP Spectre x360 Convertible

2021-03-22T12:03:10+00:00

HP Spectre x360 Convertible devices expose invalid _ADR fields in the
DSDT, which prevents codec drivers from probing. A possible solution
is to override the DSDT, but that's just too painful for users.

This patch suggests a simple DMI-based quirk to remap the existing
invalid ADR information into valid ones.

soundwire: Add generic bandwidth allocation algorithm

2020-09-18T12:18:51+00:00

This algorithm computes bus parameters like clock frequency, frame
shape and port transport parameters based on active stream(s) running
on the bus.

Developers can also implement their own .compute_params() callback for
specific resource management algorithm, and set if before calling
sdw_add_bus_master()

Credits: this patch is based on an earlier internal contribution by
Vinod Koul, Sanyog Kale, Shreyas Nc and Hardik Shah. All hard-coded
values were removed from the initial contribution to use BIOS
information instead.

soundwire: Replace 'objs' by 'y'

2020-06-22T11:36:08+00:00

`-objs` is designed for building host programs, change to `-y`,
more straightforward for device drivers.

soundwire: intel: use a single module

2020-05-20T13:54:55+00:00

It's not clear why we have two modules for the Intel controller/master
support when there is a single Kconfig. This adds complexity for no
good reason, the two parts need to work together anyways.

soundwire: add Slave sysfs support

2020-05-20T11:52:41+00:00

Expose MIPI DisCo Slave properties in sysfs.

For Slave properties and Data Port 0, the attributes are managed with
simple devm_ support.

A Slave Device may have more than one Data Port (DPN), and each Data
Port can be sink or source. The attributes are created dynamically
using pre-canned macros, but still use devm_ with a name attribute
group to avoid creating kobjects - as requested by GregKH. In the
_show function, we use container_of() to retrieve port number and
direction required to extract the information.

Audio modes are not supported for now. Depending on the discussions
the SoundWire Device Class, we may add it later as is or follow the
new specification.
