But for doing that it needs to know which OPPs to pick from the table as, in cases like yours or qcom, not all OPPs might be available. One of the ways to do that is: - the platform reads its efuses (or whatever) and encodes the information into a string. - This string should match with the strings present (somewhere) in the OPP table. That location can be like what I proposed few mails back. - Then the *generic* OPP code can parse only those OPP nodes which match with that string. This way, we can avoid pushing the platform code to parse OPP tables. > Back to my question; how would you like arbitrary version information, > which means different things to different vendors to be used in > shared/generic/framework code? Exactly like I wrote above. The platform just needs to give a string that should match with the OPPs .. -- viresh -- 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
