| Series | ARM: dts: at91: sama5d29_curiosity: Add device tree for sama5d29_curiosity board | expand |
Hey, Firstly, $subject is missing a "v2" inside the []s.

Perhaps Claudiu would be willing to fix it, but certainly for future versions this needs fixing. Thanks, Conor. > > Signed-off-by: Mihai Sain <mihai.sain@microchip.com> > ---

I don't understand who is saying what here.

We have added in dt-overlay the codec which uses the i2s0 and i2c1 nodes and pinctrls. overlay means additional DT bindings to me. So, I suggest to move the i2s node there, too. It is the same approach that you've taken for ethernet node.

Add initial device tree file for sama5d29_curiosity board. Changes in v2: * drop dt-bindings patch * remove vdd_1v8 regulator * fix flx4 node to use 1 spi node and pinctrl * add i2s0 node and pinctrl * remove macb0 node and pinctrl * remove unused pinctrl * sort in alphabetical order all nodes and pinctrl * replace "_" with "-" in node names Signed-off-by: Mihai Sain <mihai.sain@microchip.com> --- arch/arm/boot/dts/microchip/Makefile | 2 + .../dts/microchip/at91-sama5d29_curiosity.dts | 615 ++++++++++++++++++ 2 files changed, 617 insertions(+) create mode 100644 arch/arm/boot/dts/microchip/at91-sama5d29_curiosity.dts
