The same definition could be written in the following form:

pcm.hdspm_112 {
	type multi
	slaves.a {
		pcm hdspm_0
		channels 56
	}
	slaves.b {
		pcm hdspm_1
		channels 56
	}
	bindings [
		{ slave a channel  0 }
		{ slave a channel  1 }
		{ slave a channel  2 }
		...
		{ slave a channel 55 }
		{ slave b channel  0 }
		...
		{ slave b channel 55 }
	]
}
