Subject: [PATCHv3 3/3] ARM: OMAP4: hwmod_data: add opt clks for dss_hdmi and dss_venc
Date: Thu, 18 May 2017 20:16:12 +0300	[thread overview]
Message-ID: <1495127772-7486-4-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1495127772-7486-1-git-send-email-t-kristo@ti.com>

These extra optional clocks are required as main clock for these modules
are going to be routed to the main module clock. Otherwise, the hdmi / tv
clocks are not going to be enabled during usage, leading to failure.
