-Subject: i2c: i2c-qcom-geni: Add shutdown callback for i2c
-
-From: Roja Rani Yarubandi <rojay@codeaurora.org>
-
-[ Upstream commit e0371298ddc51761be257698554ea507ac8bf831 ]
-
-If the hardware is still accessing memory after SMMU translation
-is disabled (as part of smmu shutdown callback), then the
-IOVAs (I/O virtual address) which it was using will go on the bus
-as the physical addresses which will result in unknown crashes
-like NoC/interconnect errors.
-
-So, implement shutdown callback to i2c driver to stop on-going transfer
-and unmap DMA mappings during system "reboot" or "shutdown".
-
-Fixes: 37692de5d523 ("i2c: i2c-qcom-geni: Add bus driver for the Qualcomm GENI I2C controller")
