patch "serial: 8250_pci: Enumerate Elkhart Lake UARTs via dedicated driver" added to tty-linus

This is a note to let you know that I've just added the patch titled

serial: 8250_pci: Enumerate Elkhart Lake UARTs via dedicated driver

to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: serial: 8250_pci: Enumerate Elkhart Lake UARTs via dedicated driver

Elkhart Lake UARTs are PCI enumerated Synopsys DesignWare v4.0+ UART integrated with Intel iDMA 32-bit DMA controller. There is a specific driver to handle them, i.e. 8250_lpss. Hence, disable 8250_pci enumeration for these UARTs.
