Subject: [PATCH 0/5] i2c: clock calculation cleanups for Renesas devices
Date: Wed, 6 Sep 2023 22:00:18 +0200 [thread overview]
Message-ID: <20230906200024.5305-1-wsa+renesas@sang-engineering.com> (raw)
While implementing FastMode+ support for the R-Car IP core, I noticed
potential for other cleanups. It turned out that it makes sense to apply
them first, so here is the series. Tested on a Renesas Falcon board with
an R-Car V3U. The calculated values are identical for 100 and 400kHz.
The RIIC patch is build tested only.
Looking forward to comments!
Wolfram Sang (5):
i2c: rcar: avoid non-standard use of goto
i2c: rcar: properly format a debug output
i2c: rcar: calculate divider instead of brute-forcing it
i2c: rcar: remove open coded DIV_ROUND_CLOSEST
i2c: riic: avoid potential division by zero
