From 974c7c6d7ba5a4b12d99456b0599aa6326dc2b69 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Thu, 7 Jun 2018 16:39:59 +0930 Subject: [PATCH] clk: aspeed: Mark bclk (PCIe) and dclk (VGA) as critical This is used by the host to talk to the BMC's PCIe slave device. The BMC is not involved, but the clock needs to be enabled so the host can use the device.
