[alsa-devel] [PATCH 15/17] AsoC: Intel: Add quirks for MinnowBoard MAX

[Pierre-Louis Bossart]

From: Irina Tirdea <irina.tirdea at intel.com>

I2S MCLK has been routed to LSE connector on the MinnowBoard
starting with HW version 3. Older versions of the board do
not have MCLK wired.

Add dmi quirk to disable MCLK for MinnowBoard MAX (v2).
