Subject: [PATCH v4 4/4] soc: sunxi: sram: Only iterate over SRAM children
Date: Thu, 24 Nov 2022 22:01:12 -0600	[thread overview]
Message-ID: <20221125040112.18160-5-samuel@sholland.org> (raw)
In-Reply-To: <20221125040112.18160-1-samuel@sholland.org>

Now that a regulators child is accepted by the controller binding, the
debugfs show routine must be explicitly limited to mmio-sram children.
