[PATCH v2 00/20] Add support for Silicon Labs WiFi chip WF200 and further

[Jerome Pouiller]

From: JÃrÃme Pouiller <jerome.pouiller@xxxxxxxxxx>

Hello all,

This series add support for Silicon Labs WiFi chip WF200 and further:

   https://www.silabs.com/documents/public/data-sheets/wf200-datasheet.pdf

This driver is an export from:

   https://github.com/SiliconLabs/wfx-linux-driver/
   
I squashed all commits from github (it definitely does not make sense to
import history). Then I split it in comprehensible (at least try to be)
commits. I hope it will help readers to understand driver architecture.
IMHO, firsts commits are clean enough to be reviewed. Things get more
difficult when I introduce mac8011 API. I tried to extract important
parts like Rx/Tx process but, big and complex patches seem unavoidable
in this part.

Architecture itself is described in commit messages.

The series below is aligned on version 2.3.1 on github. If compare this
series with github, you will find traditional differences between
external and a in-tree driver: Documentation, build infrastructure,
compatibility with older kernel revisions, etc... In add, I dropped all
code in CONFIG_WFX_SECURE_LINK. Indeed, "Secure Link" feature depends
on mbedtls and I don't think to pull mbedtls in kernel is an option
(see "TODO" file in first commit).


Changes in v2:
  - Add TODO file (and dropped todo list from cover letter)
  - Drop code relative to compatibility with older kernels
