> Best regards,
This series has undergone many iterations mostly driven by Sashiko alone.
I was hoping for some human review on the dts parts before re-submitting.
Anything holding up this series? Any guidance?
We are planning to submit RZ/V2N based boards too, and the older SoCs
in this series were the testing ground on upstream acceptance.
Sashiko had two minor nits on this series:
Patch 7: using ronbo compatible string when panel vendor is winstar.
The *only* in-tree user of the compatible is:
arch/arm64/boot/dts/freescale/imx8mp-hummingboard-iiot-panel-dsi-WJ70N3TYJHMNG0.dtso:
/* This is a Winstar panel, but the ronbo panel uses same
controls. */
arch/arm64/boot/dts/freescale/imx8mp-hummingboard-iiot-panel-dsi-WJ70N3TYJHMNG0.dtso:
compatible = "ronbo,rb070d30";
So I still feel it unnecessary to add a different vendor for name sake only.
Maintainers please correct me if necessary.
Patch 8: which specific dtsi file should include <dt-bindings/leds/common.h>
Minor and easy to fix.
