From 47fabc9cbc05bd5ebc70e1953d118d2a424df841 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Cl=C3=A9ment=20P=C3=A9ron?= Date: Fri, 7 Jun 2019 20:10:48 -0300 Subject: [PATCH] media: dt-bindings: media: sunxi-ir: Add A31 compatible MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Allwinner A31 has introduced a new memory mapping and a reset line. The difference in memory mapping are : - In the configure register there is a new sample bit and Allwinner has introduced the active threshold feature. - In the status register a new STAT bit is present. Note: CGPO and DRQ_EN bits are removed on A31 but present on A13 and on new SoCs like A64/H6. This is actually not an issue as these bits are togglable and new SoCs have a dedicated bindings. Introduce this bindings to make a difference since this generation. And declare the reset line required since A31.
