Subject: [PATCH 2/2] net: mwifiex: add support for the SD8777 chipset
Date:   Sun, 29 Oct 2023 12:08:17 +0100

Marvell SD8777 is a wireless chipset used for instance in the PXA1908
SoC found for example in the samsung,coreprimevelte smartphone, with
which this was tested. The driver seems to be compatible with this
chipset so enable this support by adding the necessary information based
on the downstream code.
