My apologies, misunderstood the error. Proposed changes for the next version, Add dma, dma-names, reg-names properties, and do the changes in example (rename node to mcpdm since it is different from generic pdm). reg-names: items: - const: mpu - const: dma dmas: maxItems: 2 dma-names: items: - const: up_link - const: dn_link examples: - | #include <dt-bindings/interrupt-controller/arm-gic.h> mcpdm@0 { compatible = "ti,omap4-mcpdm"; reg = <0x0 0x7f>, /* MPU private access */ <0x49032000 0x7f>; /* L3 Interconnect */ reg-names = "mpu", "dma"; interrupts = <GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>; interrupt-parent = <&gic>; dmas = <&sdma 65>, <&sdma 66>; dma-names = "up_link", "dn_link"; ti,hwmods = "mcpdm"; clocks = <&twl6040>; clock-names = "pdmclk"; }; Remove ti.hwmods from required since some dts like omap4-duovero-parlor, omap4-panda etc do not use it which causes dtbs_check to not pass. -- Best Regards, Mithil
