From 535e73cdbf766801e8a4d2be036f50c8db0f0213 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 6 May 2019 14:08:54 -0700 Subject: [PATCH] clk: ti: clkctrl: Fix clkdm_clk handling [ Upstream commit 1cc54078d104f5b4d7e9f8d55362efa5a8daffdb ] We need to always call clkdm_clk_enable() and clkdm_clk_disable() even the clkctrl clock(s) enabled for the domain do not have any gate register bits. Otherwise clockdomains may never get enabled except when devices get probed with the legacy "ti,hwmods" devicetree property.
