[PATCH 0/2] arm64: dts: tegra: smaug: Add Wi-Fi and BT DT nodes

[Diogo Ivo]

Hello,

These patches add DT nodes separately for the BRCM4354 Wi-FI + BT combo
module in the Pixel C, and have both been tested on it.

Thanks!

Both patches applied, thanks!

Given that this is a rather old device that we rarely see third party
contributions for, would you mind sharing some details on your setup?
Are you running any of the after market OSes on this?

Hello,

I am running the latest Arch Linux ARM image on it, and the 5.19 kernel,
which allow the device to be used from the TTY, since there are
some bugs in the graphics stack preventing a full desktop environment.

Best regards,
Diogo
