Subject: [PATCH 1/7] dt-bindings: timer: renesas, cmt: Add CMT0234 to sh73a0 and r8a7740
Date: Thu, 18 Jul 2019 20:44:12 +0900 [thread overview]
Message-ID: <156345025207.5307.17135263586186534810.sendpatchset@octo> (raw)
In-Reply-To: <156345023791.5307.6113391102648394591.sendpatchset@octo>
From: Magnus Damm <damm+renesas@opensource.se>
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.
