Description
Describe the bug
Serial communication using sc16is7xx randomly fail to send data. Receiving doesn’t seems to be affected.
Issue appears with one port or more ports used in parallel but it does not seems related to the loading or amount of data transmitted.
Last working kernel version was 5.4.83-v7+ - Raspberry Pi reference 2021-06-15 -Generated using pi-gen, https://github.com/RPi-Distro/pi-gen, bf8c9f53833016e1b9410d2eb3ed0149390975a7.
Rebuilding kernel 5.10.17-v7+ with sc16is7xx driver from 5.4.83-v7+ commit 5da6b1c079e6804a81e63ab8337224cbd2148c91 didn't solve the problem.
In our program (not the linux-serial-test) we got randomly 4096 bytes in buffer and this was the reason to link the issue to the kernel tty.
Versions above 5.4.83-v7+ also have the #4228 issue.
To reproduce
Raspberry Pi 3 Model B+
SD image: 2021-10-30-raspios-bullseye-armhf-lite.zip
Custom board witn 2 x SC16IS752 and tpm-slb9670 (@pelwell has one)

Set /boot/cmdline.txt:
console=serial0,115200 console=tty1 root=PARTUUID=e94b1ac0-02 rootfstype=ext4 fsck.repair=yes rootwait
Update system, enable I2C, SPI and autologin to console:
sudo apt update && sudo apt install -y git &&\
sudo raspi-config nonint do_i2c 0 &&\
sudo raspi-config nonint do_spi 0 &&\
SUDO_USER="${FIRST_USER_NAME}" sudo raspi-config nonint do_boot_behaviour B2 &&\
sudo poweroff
List serial ports available to check that sc16is752 is loaded: ls /dev/ttyS*
Clone and build linux-serial-test:
git clone --depth 1 https://github.com/cbrake/linux-serial-test &&\
cd linux-serial-test &&\
gcc -o linux-serial-test linux-serial-test.c
Expected behaviour
All data sent (Tx) should be received (Rx) using a loopback cable or just conecting Rx to Tx of same port.
Actual behaviour
Some date is not transmitted so not received.
Using an ttyUSB0 is OK:
