Subject: [PATCH v4 1/6] ARM: dts: dra762: Add MCAN clock support
Date: Thu, 5 Jul 2018 19:53:14 +0530	[thread overview]
Message-ID: <20180705142319.19583-2-faiz_abbas@ti.com> (raw)
In-Reply-To: <20180705142319.19583-1-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.
