Subject: [PATCH 2/3] bus: ti-sysc: Detect display subsystem related devices
Date:   Mon, 24 Feb 2020 11:12:29 -0800

Precedence: bulk

In order to prepare probing display subsystem (DSS) with ti-sysc
interconnect target module driver and device tree data, let's
detect DSS related modules.

We need to also add reset quirk handling for DSS, but until that's
done, let's just enable the optional clock quirks for DSS and
omap4 HDMI. The rest is just naming of modules if CONFIG_DEBUG
is set.
