Subject: [PATCH 1/2] ASoC: Intel: baytrail: Fix register access
Date: Thu,  7 May 2020 09:34:04 -0400	[thread overview]
Message-ID: <20200507133405.32251-1-amadeuszx.slawinski@linux.intel.com> (raw)

Baytrail has 64 bit registers, so we should use *read64* to read from it
and then use proper mask values to check status.
