48c2ecf20Sopenharmony_ciDescription:
58c2ecf20Sopenharmony_ci		DMA buffers tend to have a alignment requirement for the
68c2ecf20Sopenharmony_ci		buffers. If this alignment requirement is not met samples might
78c2ecf20Sopenharmony_ci		be dropped from the buffer.
88c2ecf20Sopenharmony_ci
98c2ecf20Sopenharmony_ci		This property reports the alignment requirements in bytes.
108c2ecf20Sopenharmony_ci		This means that the buffer size in bytes needs to be a integer
118c2ecf20Sopenharmony_ci		multiple of the number reported by this file.
128c2ecf20Sopenharmony_ci
138c2ecf20Sopenharmony_ci		The alignment requirements in number of sample sets will depend
148c2ecf20Sopenharmony_ci		on the enabled channels and the bytes per channel. This means
158c2ecf20Sopenharmony_ci		that the alignment requirement in samples sets might change
168c2ecf20Sopenharmony_ci		depending on which and how many channels are enabled. Whereas
178c2ecf20Sopenharmony_ci		the alignment requirement reported in bytes by this property
188c2ecf20Sopenharmony_ci		will remain static and does not depend on which channels are
198c2ecf20Sopenharmony_ci		enabled.
