From bb09bd5f6913c69a94a89cbc6e6576b5fb3a4c11 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Thu, 12 Sep 2019 09:17:09 +0000 Subject: [PATCH] arm: mxs: fix register definitions for clkctrl_gpmi and clkctrl_sspX I tried clearing a bit by writing to hw_clkctrl_gpmi_clr, then busy-waiting for it to actually clear. My board hung. The data sheet agrees, these registers do not have _set, _clr, _tog, so fix up the definitions. git grep -E 'clkctrl_(gpmi|ssp[0-9])_' says that nobody uses those non-existing ops registers.
