Subject: [PATCH v4 12/25] firmware: xilinx: Remove eemi ops for reset_assert
Date: Thu,  9 Apr 2020 12:12:01 -0700	[thread overview]
Message-ID: <1586459534-8997-13-git-send-email-jolly.shah@xilinx.com> (raw)
In-Reply-To: <1586459534-8997-1-git-send-email-jolly.shah@xilinx.com>

From: Rajan Vaja <rajan.vaja@xilinx.com>

Use direct function call instead of using eemi ops for
reset_assert.
