Subject: [PATCH] arm64: zynqmp: zynqmp-zcu106-revA: Fix DP PLL configuration
Date: Thu,  5 May 2022 10:56:29 +0200	[thread overview]
Message-ID: <62538b4a04dee28a6fc8ac5b85f8c845a5a76aa4.1651740988.git.michal.simek@amd.com> (raw)

From: Neal Frager <neal.frager@amd.com>

This patch fixes the DP audio and video PLL configurations
for the zynqmp-zcu106-revA evaluation board.

The Linux DP driver expects the DP to be using the following PLL config:
  - DP video PLL should use the VPLL (0x0)
  - DP audio PLL should use the RPLL (0x3)

Register 0xFD1A0070 configures the DP video PLL.
Register 0xFD1A0074 configures the DP audio PLL.
