SHort summary: can we use a single image for all 5.4 platforms (by using v5 signatures, by using v6 signatures, v3 or any other kind of quirk).Thanks for your comment. We have discussed with the firmware team and other teams if we can use the same firmware binary. The result is we'd better use different firmware files. They should respond in the firmware binary thread. I will push them and hope them respond as quickly as possible and give reasons.+}; + static const struct freq_tbl sdm660_freq_table[] = { { 979200, 518400000 }, { 489600, 441600000 }, @@ -937,6 +986,7 @@ static const struct of_device_id venus_dt_match[] = { { .compatible = "qcom,msm8916-venus", .data = &msm8916_res, }, { .compatible = "qcom,msm8996-venus", .data = &msm8996_res, }, { .compatible = "qcom,msm8998-venus", .data = &msm8998_res, }, + { .compatible = "qcom,qcs615-venus", .data = &qcs615_res, },The hardware seems to be the same as sc7180, only the frequencies differ. Can we change the driver in a way that we don't have to add another compat entry just for the sake of changing freqs / bandwidths?Thank you for your comment. I agree with you. But based on the Venus code architecturE ANd the distinction between different platforms, I think the current changes are the simplest.Well, it is simplest, correct. But not the best one. There is no plan no migrate these platforms to the iris driver. So instead, please improve the venus driver instead of just pushing the simplest change. I should have been more explicit about it earlier.
Based on the current code architecture, I don't know if there is a better way. If we
refactor the code, it will take a lot of effort. Therefore, I submit this change. Do you have a better approach? Also, the driver architecture of iris is implemented as you said.
