From b1bcd61665646d3f44e6d0e94a3ef946417027ca Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Thu, 2 Apr 2020 17:11:21 +0530 Subject: [PATCH] clk: rk3399: Set empty for vopl assigned-clocks During vidconsole probe, the device probe will try to check whether the assigned clocks on that video console node is initialized or not? and return an error if not. But, unlike Linux U-Boot won't require to handle these vopl assigned-clocks since core clocks are enough to handle the video out to process. So, mark them as empty in set_rate to satisfy clk_set_defaults so-that probe happened properly.
