[PATCH 00/31] staging/wfx: apply suggestions from the linux-wireless review

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Most of the patches of this series are the result of the review process on
linux-wireless[1].

The patches 1 to 25 are cosmetics. The last 3 patches are not fully backward
compatible. I believe it is not a problem in the staging area.

Is the Apache-2.0 license really mandatory? LICENSES/dual/Apache-2.0 is
not really supportive.

[usual "I am not a lawyer" preamble]

hmm... I don't think it is really mandatory. However, I would more
confident if we could keep the original license also (I think the idea
behind is to not prevent someone to reuse this header in any other
project).

[PATCH 11/31] staging: wfx: preserve endianness of struct hif_ind_startup

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

The hardware fills struct hif_ind_startup with little endian values. So,
declare it with little endian fields.

It is now a bit more verbose to access to fields of struct
hif_ind_startup, but it is less confusing.

[PATCH 15/31] staging: wfx: prefix functions from hwio.h with wfx_

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

All the functions related to a driver should use the same prefix.

[PATCH 19/31] staging: wfx: prefix structs tx_policy and hwbus_ops with wfx_

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

All the types related to a driver should use the same prefix.

[PATCH 20/31] staging: wfx: reformat code on 100 columns

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Until now, this driver was written in 80 columns style. However, since
all the functions are prefixed with "wfx_", this constraint is no more
respected in the last patches.

From the perspective of kernel Coding Style, it is not a problem since
it is now allowed to write code on 100 columns.

This patch just unify the code to use 100 columns.

Signed-off-by: Jérôme Pouiller <jerome.pouiller@silabs.com>

[PATCH 21/31] staging: wfx: reformat comments on 100 columns

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Until now, this driver was written in 80 columns style. However, since
all the functions are prefixed with "wfx_", this constraint is no more
respected in the last patches.

From the perspective of kernel Coding Style, it is not a problem since
it is now allowed to write code on 100 columns.

This patch just unify the code to use 100 columns in every comments.

Signed-off-by: Jérôme Pouiller <jerome.pouiller@silabs.com>

[PATCH 25/31] staging: wfx: do not display functions names in logs

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

It is not necessary to prefix error logs with the function name when an
error message is unique in the code.

Note this patch still prefixes the message 'received event for
non-existent vif' with the function name since it is used several
times.

[PATCH 26/31] staging: wfx: remove force_ps_timeout

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

ps_timeout should be in nl80211, not in debugfs. Let's remove it until
the driver is accepted.

[PATCH 27/31] staging: wfx: map 'compatible' attribute with board name

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

"WF200" only designates the chip. To make a WiFi board, the chip must be
associated with an antenna. The antenna configuration is located in
separate files (aka PDS files in Silabs wording). Currently, user has to
write in his DT something like:

    compatible = "silabs,wf200";
    config = "brd4001a.pds";

It is far better to embed a list of known boards (chip + antenna) in the
driver. So the user just have to declare:

    compatible = "silabs,brd4001a";

This patch add the configurations for the evaluation boards sold by
Silabs. To provide a full plug-and-play experience, the associated PDS
files[1] will be available in linux-firmware.

This patch does not break compatibility with existing setups.

[PATCH 28/31] staging: wfx: fix firmware location

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

There is currently, a mismatch between the location of the firmware in
linux-firmware and the path written in the driver.

We take this opportunity to relocate the WF200 firmware in wfx/ instead
of silabs/.

[PATCH 29/31] staging: wfx: drop legacy compatible values

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Values "silabs,wfx-sdio" and "silabs,wfx-spi" are deprecated for a while
now. We take advantage of getting out of the staging tree to drop them
and start from a blank sheet.

[PATCH 30/31] staging: wfx: rename "config-file" DT attribute

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

"config-file" is too broad. Replace it by "silabs,antenna-config-file"
which is more explicit.

The attribute "config-file" is probably not widely used. This patch
obviously breaks setups that use this attribute.

[PATCH 31/31] staging: wfx: do not probe the device if not in the DT

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Since the WF200 VID/PID are not reliable, it's recommended to declare it
in the DT. Until now, if the device was not declared, the driver just
printed a warning and continue. But, the risk of a collision is too
high, the driver now returns an error.
