From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Subject: [PATCH 1/7] dt-bindings: timer: renesas, cmt: Add CMT0234 to sh73a0 and r8a7740 Date: Thu, 18 Jul 2019 20:44:12 +0900 Message-ID: <156345025207.5307.17135263586186534810.sendpatchset@octo> References: <156345023791.5307.6113391102648394591.sendpatchset@octo> Return-path: In-Reply-To: <156345023791.5307.6113391102648394591.sendpatchset@octo> Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org Cc: mark.rutland@arm.com, devicetree@vger.kernel.org, geert+renesas@glider.be, daniel.lezcano@linaro.org, linux-renesas-soc@vger.kernel.org, robh+dt@kernel.org, Magnus Damm , tglx@linutronix.de List-Id: devicetree@vger.kernel.org From: Magnus Damm Document the on-chip CMT devices included in r8a7740 and sh73a0. Included in this patch is DT binding documentation for 32-bit CMTs CMT0, CMT2, CMT3 and CMT4. They all contain a single channel and are quite similar however some minor differences still exist: - "Counter input clock" (clock input and on-device divider) One example is that RCLK 1/1 is supported by CMT2, CMT3 and CMT4. - "Wakeup request" (supported by CMT0 and CMT2) Because of this one unique compat string per CMT device is selected.
