Subject: [v3 4/7] mfd: intel_soc_pmic_core: ADD PWM lookup table for CRC PMIC based PWM
Date: Fri, 26 Jun 2015 14:32:07 +0530 [thread overview]
Message-ID: <1435309330-50725-5-git-send-email-shobhit.kumar@intel.com> (raw)
In-Reply-To: <1435309330-50725-1-git-send-email-shobhit.kumar@intel.com>
On some BYT PLatform the PWM is controlled using CRC PMIC. Add a lookup
entry for the same to be used by the consumer (Intel GFX)
