Below mentioned register sequence should be part of acp init sequence. 1) Set ACP clock mux selection register to ACP_ACLK clock source. 2) Enable ACP global interrupt enable register 3) Enable ACP error interrupt mask. ACP reset sequence should contain code related to asserting acp soft reset and release the soft reset. Move the rest of the registers programming to acp init sequence.
