Hi, the following patch: 77a82cebf0eb serial: sc16is7xx: Put IOControl register into regmap_volatile Was introduced in kernel 6.5. Without it, the debugfs register display can be incorrect for this register. I would like it to be applied to the stable kernel 6.1. It applies cleanly and was tested on this kernel using a custom board with a Variscite IMX8MN NANO SOM, a NewHaven LCD, and two SC16IS752 on a SPI bus. Thank you, Hugo Villeneuve
