Dear Renesas Open Source team, We've recently switched from rcar-3.7.x to rcar-3.9.x [1] kernel and the latter contains this patch [2] by virtue of rcar-3.9.0 commit [3], which mirrors v4.18-rc1 commit [4] in mainline. JFYI, quite far away in the delivery chain, we've received below report: > With this patch [2-4] there are reports about broken data > communication with 115200 baud with SXM module. Reverting > this patch results in successful communication, again. While this scarce information barely helps anybody, I thought that sharing it with you might be beneficial in case you collect several reports linked to this specific commit in future, meaning it potentially adds a regression. Also, if you are aware of any userland changes that might be required/assumed by this patch or in case you have any alternative ideas how to avoid reverting this patch, your feedback would be very appreciated.
