From ffc1fac549d72ce85205dcdde9af9dfe0f04fd76 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Fri, 28 Apr 2017 18:33:57 +0200 Subject: [PATCH] rockchip: clk: rk3399: allow requests for HDMI clocks This allows requests (via the DTS) for PCLK_HDMI_CTRL/PCLK_VIO_GRF, which are clock gates in the HDMI output path for the RK3399. As these are enabled by default (i.e. after reset), we don't implement any logic to actively open/close these clock gates and simply assume that their reset-default has not been changed.
