Subject: [PATCH 0/2] OMAP2/3: fix the i2c,gpio reset timeouts during boot.
Date: Fri, 1 Apr 2011 21:04:05 +0530 [thread overview]
Message-ID: <1301672047-31903-1-git-send-email-avinashhm@ti.com> (raw)
Hi ,
The patches solve the reset timeouts seen in i2c and gpio modules while
booting omap2 and omap3.
Baseline:
The patches are based on
* git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git
* master branch.
* v2.6.39-rc1 commit (0ce790e)
Testing:
* build tested omap2plus_defconfig for warnings and errors. none introduced.
* boot tested on 2430.
* tested for 'core off' in suspend resume on 3430 sdp. core off counters
increment after suspend resume. Core off works with below commands,
echo 1 > /debug/pm_debug/enable_off_mode
echo mem > /sys/power/state
cat /debug/pm_debug/count | grep ^core
Dependencies:
* need patch "OMAP2+: hwmod data: Set hwmod flags to only allow 16-bit
accesses to i2c" from Andry Green for accessing i2c_sysc. Without this even
with this patch, we will see i2c reset timeouts.
