From dc8fbeb0ffde1f2395449006019e2c89c177df50 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Fri, 22 Jun 2018 00:41:26 +0200 Subject: ARM: OMAP1: Get rid of Split the header file into two parts and move them to directories where they belong. Information on internal structure of FIQ buffer is moved to for ams-delta-serio driver use. Other information used by ams-delta board init file and FIQ code is made local to mach-omap1 root directory.
