Is there a > name for the input line on the JPEG block this is plugged into? There is unfortunately no such name for SCLK_JPEG clock in the IP's block documentation. For most of the multimedia IPs clocks are documented only in the clock controller chapter, hence the names may appear global. Probably "gate", "sclk" would be good names, rather than "<IP_NAME>", "<IP_NAME>-sclk". But people kept using the latter convention and now it's spread all over and it's hard to change it. Since now we can't rename "jpeg" and other IPs I'd assume it's best to stay with "jpeg", "sclk-jpeg". -- Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
