Subject: [PATCH v5 6/8] clk: core: Avoid double initialization of clocks
Date: Tue,  5 Jul 2016 18:23:32 +0200	[thread overview]
Message-ID: <1467735814-23518-9-git-send-email-ricardo.ribalda@gmail.com> (raw)
In-Reply-To: <1467735814-23518-1-git-send-email-ricardo.ribalda@gmail.com>

Some clock providers can be initialized via of_clk_init() and also via
platform device probe.

Avoid double initialization of them by setting the OF_POPULATED flag.
