From f95440ca5bdd3ed3e31c2fbad07b9056b31ad18c Mon Sep 17 00:00:00 2001 From: "Avinash.H.M" Date: Tue, 5 Apr 2011 21:10:15 +0530 Subject: OMAP2/3: hwmod: fix gpio-reset timeouts seen during bootup. GPIO module expects the debounce clocks to be enabled during reset. It doesn't reset properly and timeouts are seen, if this clock isn't enabled during reset. Add the HWMOD_CONTROL_OPT_CLKS_IN_RESET flags to the GPIO HWMODs, with which the debounce clocks are enabled during reset.
