From mboxrd@z Thu Jan 1 00:00:00 1970 From: mylene.josserand@free-electrons.com (=?UTF-8?q?Myl=C3=A8ne=20Josserand?=) Date: Tue, 31 Jan 2017 11:05:45 +0100 Subject: [PATCH v3 1/8] ASoC: sun4i-i2s: Update binding documentation to include A31 In-Reply-To: <20170131100552.27949-1-mylene.josserand@free-electrons.com> References: <20170131100552.27949-1-mylene.josserand@free-electrons.com> Message-ID: <20170131100552.27949-2-mylene.josserand@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add a new compatible for sun4i-i2s driver to handle some SoCs that have a reset line that must be asserted/deasserted. This new compatible, "allwinner,sun6i-a31-i2s", requires the property "resets" which should be a phandle to the reset line. Except these differences, the compatible is identical to previous one which will not handle a reset line.
