From dec85a95167a98a4e237df11e234eed8ee718e78 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 20 Sep 2022 00:16:17 +0200 Subject: [PATCH] ARM: davinci: clean up platform support With the board file support gone, and the platform using DT only, a lot of the remaining code is no longer referenced and can be removed. Technically, the DT file only references DA850, but since that is very similar to DA830, I'm leaving the latter.
