From mboxrd@z Thu Jan 1 00:00:00 1970 From: prabhakar.mahadev-lad.rj@bp.renesas.com (Lad Prabhakar) Date: Sat, 1 Feb 2020 12:26:51 +0000 Subject: [cip-dev] [PATCH 4.19.y-cip 03/14] dt-bindings: i2c: sh_mobile: Rename bindings documentation file In-Reply-To: <1580560022-26873-1-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com> References: <1580560022-26873-1-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com> Message-ID: <1580560022-26873-4-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com> To: cip-dev@lists.cip-project.org List-Id: cip-dev.lists.cip-project.org From: Simon Horman commit 23c2556d8fbec57e72e2c8fd8b7be2715c192b25 upstream. Rename the bindings documentation file for sh_mobile I2C controller from i2c-sh_mobile.txt to renesas,iic.txt. This is part of an ongoing effort to name bindings documentation files for Renesas IP blocks consistently, in line with the compat strings they document.
