    "content": "Hello all\n\nThese small changes helped resolve issues we experienced using the\ni2c-imx driver on a multi-master bus. The device was losing\narbitration which triggered the driver to attempt to recover the bus\nrather than retry the transfer. The set stops the bus recovery\nattempts on lost arbitration and instructs the driver to retry\ntransfers 3 times, which seems sufficient for our setup.\n\nI had intended to make a larger change that added a new devicetree\nproperty for i2c-controller.yaml that held the number of retries an\nadapter should use, and then parse that to set adap->retries. I found\na relatively old discussion on the list though in which a similar\nidea was discussed and rejected so I dropped that, but I thought I'd\nmention it in case things had changed.\n\nThanks\nDan\n\nSigned-off-by: Daniel Scally <dan.scally@ideasonboard.com>\n---\nChanges in v2:\n- Updated the commit message in v1, and added a Fixes tag.\n- Link to v1: https://lore.kernel.org/r/20260311-i2c-imx-fixes-v1-0-e625034d8202@ideasonboard.com\n\n---\nDaniel Scally (2):\n      i2c: imx: Don't recover bus when arbitration lost\n      i2c: imx: Retry failed transfers 3 times\n\n drivers/i2c/busses/i2c-imx.c | 3 ++-\n 1 file changed, 2 insertions(+), 1 deletion(-)\n---\nbase-commit: 4a181746639404023abfcb28eb6f6c66974be5a7\nchange-id: 20260311-i2c-imx-fixes-3e23164a8a8f\n\nBest regards,"
