And /* EPIT1 */ comment can be removed, it is quite clear from the same line context.

Should I also update other boards ? I only did it for imx6qdl.dtsi, but the EPIT is present in other boards but i can't test it myself. > > > + compatible = "fsl,imx6q-epit", "fsl,imx31-epit"; > > reg = <0x020d0000 0x4000>; > > interrupts = <0 56 IRQ_TYPE_LEVEL_HIGH>; > > + clocks = <&clks IMX6QDL_CLK_IPG_PER>, > > + <&clks IMX6QDL_CLK_EPIT1>; > > + clock-names = "ipg", "per"; > > + status = "disabled"; > > }; > > > > epit2: epit@20d4000 { /* EPIT2 */ > > Same as above. > > > + compatible = "fsl,imx6q-epit", "fsl,imx31-epit"; > > reg = <0x020d4000 0x4000>; > > interrupts = <0 57 IRQ_TYPE_LEVEL_HIGH>; > > + clocks = <&clks IMX6QDL_CLK_IPG_PER>, > > + <&clks IMX6QDL_CLK_EPIT2>; > > + clock-names = "ipg", "per"; > > + status = "disabled"; > > }; > > > > src: src@20d8000 { > > > > -- > With best wishes, > Vladimir

One change per one dtsi file will suffice, and I see that imx25.dtsi already contains the requested change, however probably you may want to update its compatible = "fsl,imx25-epit" line. Regarding compatibles for other imx6* SoCs, I think all of them should be documented in fsl,imxepit.txt and then added to the correspondent dtsi files one per SoC. And I forgot the outcome of one former discussion with Uwe Kleine-König, but if my bad memory serves me, we agreed that i.MX25 was released later than i.MX31, so the most generic (the last value in the list) compatible should be a compatible with i.MX31 like in imx25.dtsi:367: compatible = "fsl,imx25-gpt", "fsl,imx31-gpt"; -- With best wishes, Vladimir
