Subject: [RFC PATCH v2 3/3] ARM: dts: exynos5420: add async-bridge clocks to disp1 power domain
Date: Fri, 06 Feb 2015 11:55:54 +0100	[thread overview]
Message-ID: <1423220154-5333-1-git-send-email-a.hajda@samsung.com> (raw)
In-Reply-To: <54D48701.10105@collabora.co.uk>

FIMD and MIXER IPs in disp1 power domain have async-bridges (to GSCALER),
therefore their clocks should be enabled during power domain switch.

Hi,

This is 2nd version of the patch. After decrypting manual and discussion
with Marek I guess this set of clocks is more apropriate - async-bridges
are present in MIXER and FIMD, so their clocks should be enabled.

The 1st version worked for me due to fact I have forgot to remove
clk_ignore_unused kernel boot option during tests ;)

Regards
Andrzej
