From ef3c67b6454b8f542f50387ad481633ae30874ac Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 25 Jan 2021 21:39:48 +0200 Subject: mfd: intel_msic: Remove driver for deprecated platform Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. Commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") is also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers, remove the support for outdated platforms completely.
