But if this is the case then we might want to rename the fck clock to the correct hfclk. On top of this patch a DT patch for the affected boards will be needed after 4.16 to define the hfclk clock (or if we do not rename it, the fck). I'll send a v2 on Monday, but would like to hear your opinion on renaming fck to hfclk from 4.16 onwards (and update the documentation as well). The DT lookup is broken anyways w/o a patch similar to this.
Hi, [This is an automated email] This commit has been processed because it contains a "Fixes:" tag, fixing commit: 7e2e6c5758de mfd: twl-core: Do not create dummy pdata when booted with DT. The bot has also determined it's probably a bug fixing patch. (score: 99.0131) The bot has tested the following trees: v4.16, v4.15.15, v4.14.32, v4.9.92, v4.4.126. v4.16: Build OK! v4.15.15: Build OK! v4.14.32: Build OK! v4.9.92: Build OK! v4.4.126: Build OK! -- Thanks, Sasha-- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

When looking up the clock we must use the client->dev as device since that is the one which is probed via DT.
