Subject: [PATCH 0/2] i2c: Add new driver for Renesas RZ/V2M controller
Date: Fri, 24 Jun 2022 11:17:34 +0100 [thread overview]
Message-ID: <20220624101736.27217-1-phil.edworthy@renesas.com> (raw)
Hi,
The Renesas RZ/V2M SoC (r9a09g011) has a new i2c controller. This series
add the driver. One annoying problem is that the SoC uses a single reset
line for two i2c controllers, and unfortunately one of the controllers
is managed by some firmware, not by Linux. Therefore, the driver just
deasserts the reset.
