| |
Some devices (e.g. CYW5557x) require autobaud mode to enable FW loading. Autobaud mode can also be required on some boards where the controller device is using a non-standard baud rate when first powered on.
This patch adds a property, "brcm,uses-autobaud-mode", to enable autobaud mode selection.
