From b401d1fd805379344750dffb0e3938676a047a2a Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 29 Sep 2022 16:27:43 +0200 Subject: ASoC: pxa: remove unused board support Most PXA/MMP boards were removed, so the board specific ASoC support is no longer needed, leaving only support for DT based ones, as well as the "gumstix" and "spitz" machines that may get converted to DT later.
