From 2664b24a8c51c21b24c2b37b7f10d6485c35b7c1 Mon Sep 17 00:00:00 2001 From: Ariel D'Alessandro Date: Fri, 19 Nov 2021 12:32:45 -0300 Subject: [PATCH] ASoC: tlv320aic31xx: Add support for pll_r coefficient When the clock used by the codec is BCLK, the operation parameters need to be calculated from input sample rate and format. Low frequency rates required different r multipliers, in order to achieve a higher PLL output frequency.
