From 454b60d3360d8c3b638770c460f568513d946883 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Wed, 14 Oct 2020 01:19:28 -0500 Subject: [PATCH 301/351] ASoC: sun8i-codec: Use the provided word size The hardware supports 8 to 24-bit word sizes on all three of its DAIs, only one of which is connected to the CPU DAI. Program the word size based on the actual selected format, instead of assuming limitations from another driver (which, incedentally, has patches pending to remove that limitation).
