This patch series enables support of i2c bus for Intel Alder Lake PCH-P and PCH-M on kernel version 5.10. These patches add ID's of Alder lake platform in these drivers: i801, intel-lpss, pinctrl. ID's were taken from linux kernel version 5.15.

Intel Alder Lake-P has the same pin layout as the Tiget Lake-LP so add support for this to the existing Tiger Lake driver.

-- 2.33.8
Have you read the kernel documentation for how to submit patches here?
I thought my bot sent this in the past, if not, here it is again:
<formletter>
This is not the correct way to submit patches for inclusion in the stable kernel tree. Please read: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly.
</formletter>
Is there something in that document that describes the format of what you submitted here?
thanks,
