From 94d5f62a91aab6ac9c3f4abfd048cbe5f77153ac Mon Sep 17 00:00:00 2001 From: Martin Povišer Date: Thu, 15 Sep 2022 11:44:42 +0200 Subject: ASoC: cs42l83: Extend CS42L42 support to new part MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The CS42L83 part is a headphone jack codec found in recent Apple machines. It is a publicly undocumented part but as far as can be told it is identical to CS42L42 except for two points: * The chip ID is different. * Of those registers for which we have a default value in the existing CS42L42 kernel driver, one register (MCLK_CTL) differs in its reset value on CS42L83. To address those two points (and only those), add to the CS42L42 driver a separate CS42L83 front.
