2019-11-14staging: align to fix warnings of line over 80 charactersJules Irenge1-25/+53
Align to fix multiple warnings of line over 80 characters. Issue detected by checkpatch tool. Signed-off-by: Jules Irenge <jbi.octave@gmail.com> Link: https://lore.kernel.org/r/20191113110052.14855-1-jbi.octave@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-10-10staging: wfx: fix spelling mistake "non existant" -> "non-existent"Colin Ian King1-1/+1
There is a spelling mistake in a dev_warn message. Fix it. Signed-off-by: Colin Ian King <colin.king@canonical.com> Link: https://lore.kernel.org/r/20191010095748.17047-1-colin.king@canonical.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-10-04staging: wfx: implement the rest of mac80211 APIJérôme Pouiller1-0/+53
Finish to fill struct ieee80211_ops with necessary callbacks. Driver is now ready to be registered to mac80211.

2019-10-04staging: wfx: allow to scan networksJérôme Pouiller1-0/+13
Chip can make foreground scan or background, but both can't be mixed in same request. So, we need to split each mac80211 requests into multiple HIF requests.

2019-10-04staging: wfx: allow to receive 802.11 framesJérôme Pouiller1-0/+23
Again, this task is more complex than it should since driver try to handle itself power saving of stations.

2019-10-04staging: wfx: allow to send 802.11 framesJérôme Pouiller1-0/+37
Three things make this task more complex than it should: - Chip necessitate to associate a link-id to each station. It is same thing than association ID but, using 8 bits only. - Rate policy is sent separately from Tx frames - Driver try to handle itself power saving of stations and multicast data Signed-off-by: Jérôme Pouiller <jerome.pouiller@silabs.com> Link: https://lore.kernel.org/r/20190919142527.31797-17-Jerome.Pouiller@silabs.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-10-04staging: wfx: add debug files and trace debug eventsJérôme Pouiller1-0/+80
Add traces when debug events happen and allow to ask internal information to chip. These features work independently from mac80211.

2019-10-04staging: wfx: setup initial chip configurationJérôme Pouiller1-0/+11
A few tasks remain to be done in order to finish chip initial configuration: - configure chip to use multi-tx confirmation (speed up data transfer) - configure chip to use wake-up feature (save power consumption during runtime) - set hardware configuration (clocks, RF, pinout, etc...) using a Platform Data Set (PDS) file On release, driver completely shutdown the chip to save power consumption. Documentation about PDS and PDS data for sample boards are available here[1]. One day, PDS data may find a place in device tree but, currently, PDS is too much linked with firmware to allowing that. This patch also add "send_pds" file in debugfs to be able to dynamically change PDS (only for debug, of course).

2019-10-04staging: wfx: introduce "secure link"Jérôme Pouiller1-0/+17
Chip support encryption of the link between host and chip. This feature is called "secure link". Driver code on github[1] support it. However, it relies on mbedtls for cryptographic functions. So, I decided to not import this feature in current patch. However, in order to keep code synchronized between github and kernel, I imported all code related to this feature, even if most of it is just no-op.

2019-10-04staging: wfx: allow to send commands to chipJérôme Pouiller1-0/+45
Chip has multiple input buffers and can handle multiple 802.11 frames in parallel. However, other HIF command must be sent sequentially. wsm_send_cmd() handles these requests. This commit also add send_hif_cmd in debugfs. This file allows to send arbitrary commands to chip. It can be used for debug and testing.

2019-10-04staging: wfx: add support for start-up indicationJérôme Pouiller1-0/+57
Once firmware is loaded, it send a first indication to host. This indication signalize that host can start to communicate with firmware. In add, it contains information about chip and firmware (MAC addresses, firmware version, etc...).
