Subject: [PATCH 3/3] clocksource/drivers/sh_cmt: Document "cmt-48" as deprecated
Date: Mon, 17 Jun 2019 19:00:32 +0900	[thread overview]
Message-ID: <156076563276.6960.9613487456512544267.sendpatchset@octo> (raw)
In-Reply-To: <156076560641.6960.5508309411424406087.sendpatchset@octo>

From: Magnus Damm <damm+renesas@opensource.se>

Update the CMT driver to mark "renesas,cmt-48" as deprecated.

Instead of documenting a theoretical hardware device based on current software
support level, define DT bindings top-down based on available data sheet
information and make use of part numbers in the DT compat string.

In case of the only in-tree users r8a7740 and sh73a0 the compat strings
"renesas,r8a7740-cmt1" and "renesas,sh73a0-cmt1" may be used instead.

Signed-off-by: Magnus Damm <damm+renesas@opensource.se>

The updated SoC-specific DT bindings are documented in:
[PATCH 2/8] dt-bindings: timer: renesas, cmt: Update CMT1 on sh73a0 and r8a7740
