From 6c38ca03406edf905c7b66ffdc8e9ea6d09b2b44 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Thu, 19 May 2022 11:17:31 -0500 Subject: dt-bindings: mfd: rk808: Convert bindings to yaml Convert the rk808 bindings into yaml format. clock-output-names varies in maxItems depending on whether or not the clock-cells is 0 or 1. For the rk805, rk809, and rk817. This preserves behavior with the existing driver handling setting the clock for these specific PMICs. When this driver is corrected and the devicetrees updated this logic can be removed (since the rk805, rk808, and rk817 only have one actual clock). Note this patch was previously sent as a series, all of the patches in the series except this one have been committed to mainline.
