Subject: [PATCH 0/4] Fix rockchip I2C bus
Date: Fri, 08 Sep 2023 12:16:45 +0200	[thread overview]
Message-ID: <20230908-bugfix-i2c-rockchip-v1-0-f8235d811f6b@wolfvision.net> (raw)

The rockchip I2C driver does not send a stop condition, this violates the
timing on the SCL line. iThe first patch fixes this and puts all related
functions on the same level.

Furthermore, we have seen nested calls to the rockchip_i2c_xfer function.
The second patch adds a check of pending interrupts and avoids
interrupting an ongoing transfer.

The last two patches propagate I2C errors from the KSZ9477 driver to the
DSA subsystem to react accordingly.
