From f21af4257cf3ec82736083dabc5fa230efebf61c Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 12 Mar 2021 10:11:24 +0200 Subject: [PATCH] ARM: OMAP2+: Stop building legacy code for dra7 and omap4/5 With the recent changes we are now booting am3/4, dra7, and omap4/5 without legacy data using devicetree, simple-pm-bus and genpd. Let's not initialize and build the legacy data unless CONFIG_OMAP_HWMOD is selected based on the SoCs enabled in .config.
