Subject: [PATCH 2/3] ARM: dts: dra762: Add MCAN clock support
Date: Sun, 8 Apr 2018 15:29:01 +0530 [thread overview]
Message-ID: <1523181542-3770-3-git-send-email-faiz_abbas@ti.com> (raw)
In-Reply-To: <1523181542-3770-1-git-send-email-faiz_abbas@ti.com>
From: Lokesh Vutla <lokeshvutla@ti.com>
MCAN is clocked by H14 divider of DPLL_GMAC. Unlike other
DPLL dividers this DPLL_GMAC H14 divider is controlled by
control module. Adding support for these clocks.
