2018-12-10ARM: dts: imx6qdl: Fix memory node duplicationMarco Franchi1-0/+1
Boards based on imx6qdl have duplicate memory nodes: - One coming from the board device tree file: memory@ - One coming from the imx6qdl.dtsi file. Fix the duplication by removing the memory node from the imx6qdl.dtsi file and by adding 'device_type = "memory";' in the board Device Tree. Converted using the following command: perl -p0777i -e 's/memory\@10000000 \{\n/memory\@10000000 \{\n\t\tdevice_type = \"memory\";\n/m' `find ./arch/arm/boot/dts -name "imx6*"`` Reported-by: Rob Herring <robh@kernel.org> Signed-off-by: Marco Franchi <marco.franchi@nxp.com> Reviewed-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2018-04-16ARM: dts: hummingboard: convert onboard audio to simple-audio-cardMatt Porter1-8/+39
The HB onboard audio currently makes use of the imx-audio-sgtl5000 binding. This binding does not support auxiliary audio devices such as external amplifiers. The simple-audio-card binding does support this property which allows systems incorporating the HB to add an auxiliary device that's attached to the HB audio jack with an overlay. Convert the HB onboard audio to use simple-audio-card for this additional flexibility.

However, the codec should always provide #sound-dai-cells regardless, so fix all the occurrences.

Pass the memory unit-adress to fix the following build warnings with W=1: Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name There are cases where dts passes an empty memory node, which will be filled by the bootloader. Passing the memory base address still allows the bootloader to fill the memory size.

The USB 2-4 regulators are fixed regulators and are always on, as they are not a VBUS supply for a single USB host port on the i.MX6, but supply VBUS to ports behind a USB hub and there is currently no way to model this in mainline.
