Subject: [PATCH v3] dt-bindings: i2c: renesas,rcar-i2c: allow 6 DMA channels
Date: Wed, 9 Sep 2026 20:35:32 +0200 [thread overview]
Message-ID: <20260909184200.3319-2-wsa+renesas@sang-engineering.com> (raw)
R-Car Gen5 can make use of it.
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

Changes since v2:
- dropped extra limits for Gen3/4 based on a discussion with Geert[1].
I dropped Conor's ack because of this being a bigger change. If
Sashiko complains again, we will ignore it
- not a a change, but after an internal discussion with Geert, we
concluded that his suggestion of raising to 8 is not fully backed
with current documentation and we keep it 6 (for now)
