From: Jerome Brunet Date: Thu, 4 Apr 2019 11:17:32 +0000 (+0200) Subject: ASoC: meson: axg-tdm-formatter: rework quirks settings X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f01bc67f58fde599b48d2dde5d0f48dccd84c4f1;p=openwrt%2Fstaging%2Fblogic.git ASoC: meson: axg-tdm-formatter: rework quirks settings The g12a tdmout requires a different signal skew offset than the axg. With this change, the skew offset is added as a parameter of the tdm formatters to prepare the addition of the g12a support.
