Subject: [PATCH 0/2] serial: sc16is7xx: fix registers accesses and Tx FIFO corruption

From: Hugo Villeneuve <hvilleneuve@...onoff.com>

Hello,
this patch series fixes enhanced/special register set accesses and Tx
FIFO corruption.

I have tested the changes on a custom board with two SC16IS752 DUART over
a SPI interface using a Variscite IMX8MN NANO SOM. The four UARTs are
configured in RS-485 mode.

Thank you.
