mm81x is the first Wi-Fi HaLow driver to support the Morse Micro mm81x chip family via USB and SDIO. S1G support in the kernel is only new, and as a result this driver has been scoped to be simple and only support station and AP interface. The Wi-Fi specific features only cover the minimum required for basic use such as powersave, aggregation, rate control and so on. The driver will be extended into the future as S1G support for operations such as ACS, channel switching and so on are added into the wireless stack. The driver has been build tested on a long list of architectures and compilers via Intels LKP. The driver currently supports IEEE80211-2024 US channels only, with AU 2020 also available. In order for this to be expanded additional non-trivial kernel work is required which will begin once the driver is upstream. The driver has had many authors who are listed below in alphabetical order: Co-developed-by: Andrew Pope <andrew.pope@morsemicro.com> Signed-off-by: Andrew Pope <andrew.pope@morsemicro.com> Co-developed-by: Arien Judge <arien.judge@morsemicro.com> Signed-off-by: Arien Judge <arien.judge@morsemicro.com> Co-developed-by: Ayman Grais <ayman.grais@morsemicro.com> Signed-off-by: Ayman Grais <ayman.grais@morsemicro.com> Co-developed-by: Bassem Dawood <bassem@morsemicro.com> Signed-off-by: Bassem Dawood <bassem@morsemicro.com> Co-developed-by: Chetan Mistry <chetan.mistry@morsemicro.com> Signed-off-by: Chetan Mistry <chetan.mistry@morsemicro.com> Co-developed-by: Dan Callaghan <dan.callaghan@morsemicro.com> Signed-off-by: Dan Callaghan <dan.callaghan@morsemicro.com> Co-developed-by: James Herbert <james.herbert@morsemicro.com> Signed-off-by: James Herbert <james.herbert@morsemicro.com> Co-developed-by: Sahand Maleki <sahand.maleki@morsemicro.com> Signed-off-by: Sahand Maleki <sahand.maleki@morsemicro.com> Co-developed-by: Simon Wadsworth <simon@morsemicro.com> Signed-off-by: Simon Wadsworth <simon@morsemicro.com> Signed-off-by: Lachlan Hodges <lachlan.hodges@morsemicro.com>
