From c90d37c9c41a572ea7183299951341b4640d5b4b Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Tue, 20 Aug 2019 21:35:03 +0900 Subject: [PATCH] dt-bindings: timer: renesas, cmt: Add CMT0234 to sh73a0 and r8a7740 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.
