Subject: [PATCH v3 1/2] ARM: OMAP2+: hwmod: AM43x: add hwmod support for ADC on AM43xx
Date: Fri, 21 Nov 2014 15:44:21 +0530 [thread overview]
Message-ID: <1416564862-23056-2-git-send-email-vigneshr@ti.com> (raw)
In-Reply-To: <1416564862-23056-1-git-send-email-vigneshr@ti.com>
This patch adds hwmod support for ADC on AM43xx. Since clockdomain
and offsets of adc_tsc are different from AM33xx, ADC data has been
directly added to AM43xx hwmod file.
