Subject: [PATCH v2] thermal: ti-soc-thermal: Add set_emul_temp hook
Date: Wed, 1 Jun 2016 09:29:10 +0530 [thread overview]
Message-ID: <1464753550-2529-1-git-send-email-j-keerthy@ti.com> (raw)
Setting the emulation temperature helps reproduce critical
temperature scenarios without risking the actual hardware at
extreme temperatures. Adding __ti_thermal_set_emul_temp as
the set_emul_temp hook.
Signed-off-by: Keerthy <j-keerthy@ti.com>

Changes in v2:
* Rebased on top of:
git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal sysfs_locking
Tested on DRA7/DRA72 baords.
