From: Franz Schnyder <redacted> The Toradex SMARC iMX95 uses the MAYA-W260 WiFi/Bluetooth module, which uses the UART interface for Bluetooth. Add UART support to enable bluetooth functionality on the MAYA-W260. Signed-off-by: Franz Schnyder <redacted> --- Although Documentation/devicetree/bindings/dts-coding-style.rst recommends an empty line between status and latest property, leave it unchanged for consistency with the rest of the file. v2: no changes --- .../dts/freescale/imx95-toradex-smarc.dtsi | 21 +++++++++++++++++++ 1 file changed, 21 insertions(+)
