From aae7948d564c614c26eb896eb8be57879146240c Mon Sep 17 00:00:00 2001 From: "Nícolas F. R. A. Prado" Date: Fri, 8 Jul 2022 15:26:05 -0400 Subject: Revert "dt-bindings: usb: mtk-xhci: Make all clocks required" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit ebc4969ae125e65fdb563f66f4bfa7aec95f7eb4. That commit was supposed to make the binding better reflect the MediaTek XHCI hardware block by requiring all clocks to be present. But doing that also causes too much noise in the devicetrees, since it requires updating old MediaTek DTs to add clock handles for the fixed clocks, and going forward every new clock added to the binding would require even more updates. The commit also didn't update the example to match the changes, causing additional warnings. Instead let's keep the clocks optional so that old devicetrees can keep omitting the fixed clocks, and we'll just add the clocks as required on new DTs.
