/*
 * For some reason the speaker amplifier is connected to the second SD line
 * (MI2S_2_D1) instead of the first (MI2S_2_D0). This must be configured in the
 * device tree, otherwise audio will seemingly play fine on the wrong SD line
 * but the speaker stays silent.
 *
 * When routing audio via QDSP6 (the default) the &lpass node is reserved and
 * the definitions from &q6afedai are used. When the modem is disabled audio can
 * be alternatively routed directly to the LPASS hardware with reduced latency.
 * The definitions for &lpass are here for completeness to simplify changing the
 * setup with minor changes to the DT (either manually or with DT overlays).
