Subject: [PATCH 5/5] ASoC: rockchip-i2s: enable "hclk" for rockchip I2S controller
Date: Sat, 13 Sep 2014 08:43:13 +0800	[thread overview]
Message-ID: <1410568993-21874-1-git-send-email-jay.xu@rock-chips.com> (raw)
In-Reply-To: <1410568723-21559-1-git-send-email-jay.xu@rock-chips.com>

As "hclk" is used for rockchip I2S controller, driver must to enable
it in probe.

Tested on RK3288 with max98090.
