Sure, sdma-imx6sl.bin is incorrect since there is no imx6sl specific sdma firmware. Instead, it reuses imx6q one. > > $ fgrep sdma-ram-script-name arch/arm/boot > arch/arm/boot/dts/imx6qdl.dtsi: fsl,sdma-ram-script-name = "imx/sdma/sdma-imx6q.bin"; > arch/arm/boot/dts/imx6sl.dtsi: fsl,sdma-ram-script-name = "imx/sdma/sdma-imx6sl.bin"; > arch/arm/boot/dts/imx51.dtsi: fsl,sdma-ram-script-name = "imx/sdma/sdma-imx51.bin"; > arch/arm/boot/dts/imx53.dtsi: fsl,sdma-ram-script-name = "imx/sdma/sdma-imx53.bin"; > > Also, last patch containing sdma firmware blobs sent to the mailing list > [1] uses "sdma-imx6.bin" name.

No, I do not think so, and that's why I sent my version with you on Cc.

I do not like the name, simply because imx6 > is not a SoC name. IMHO "sdma-imx6.bin" is much more descriptive then "sdma-imx6q.bin" in this case. It could have been named "foobar" as far as I am concerned. But because it was named "sdma-imx6q.bin" in imx6qdl.dtsi error was made when new imx6sl.dtsi was created. Naming it "sdma-imx6.bin" or "sdma-imx6x.bin" would help avoiding confusions in the future (despite it's not SoC name). Luka ^ permalink raw reply [flat|nested] 6+ messages in thread

"sdma-imx6q.bin" tells that the firmware is created for imx6q and gets reused on imx6sl, while "sdma-imx6.bin" tells nothing about that compatibility info. > > It could have been named "foobar" as far as I am concerned. But because > it was named "sdma-imx6q.bin" in imx6qdl.dtsi error was made when new > imx6sl.dtsi was created. The error is there only because the author of imx6sl.dtsi (me) was not aware of there is no imx6sl specific sdma firmware. > Naming it "sdma-imx6.bin" or "sdma-imx6x.bin" > would help avoiding confusions in the future (despite it's not SoC > name). Just for example, if the next imx6 SoC uses a different sdma firmware, I guess "sdma-imx6.bin" or "sdma-imx6x.bin" would become the source of confusion.
