Subject: [PATCH v12 33/35] ARM: tegra: Add Memory Client resets to Tegra20 GR2D, GR3D and Host1x
Date: Mon, 20 Sep 2021 21:11:43 +0300	[thread overview]
Message-ID: <20210920181145.19543-34-digetx@gmail.com> (raw)
In-Reply-To: <20210920181145.19543-1-digetx@gmail.com>

Memory access must be blocked before hardware reset is asserted and before
power is gated, otherwise a serious hardware fault is inevitable. Add
reset for memory clients to the GR2D, GR3D and Host1x nodes.
