cyw43455 driver for i.mx6ull

[zhanglei2015xx]

From Session#AMF-SOL-T3536, I know "meta-muruta-wireless" could be used for Muruta m.2 wifi+ble combo module(PN:LBEE5HY1MW, based on cyw43455), but i have no LBEE5HY1MW on hand. Instead, I 'v got Azurewave AW-CM256SM module(also based on cyw43455). Is it possible to use "meta-muruta-wireless"for   AW-CM256SM, since both have the same SDIO interface？ Thanks.

HI. To anyone who has the same question and can't find the answer - Cypress cyw43455 chip is actually is based on Broadcom BCM43xx family. This means that you do not need special drivers for any module based on it. So I would assume Murata and Azurwave modules are interchangeable as long as there are no "tricks" in Murata drivers, then again, you can just use Broadcom drivers for both of them.

I have confirmed it using 1MW and Armbian Linux on custom hardware that it runs with out-of-the-box Broadcom driver included in current mainline kernel:

Hi felix

different modules may require different firmware, may be useful to post it on murata support link

Best regards
