Cover letter [PATCH v2 0/3] serial: lantiq: Update driver to support new SoC
There is a new Intel Atom based Lightning Mountain(LGM) network processor SoC which reuses Lantiq ASC serial controller IP. This patch series updates the driver design and code to add support for LGM SoC as well.
These patches are baselined upon Linux 5.3-rc2 at below Git tree:git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
Patch 1 modifies devicetree compatible string to a use explicit string instead of a fixed macro because this patch series adds support for multiple SoCs.
Patch 2 modifies driver design to support dynamic assignment of IRQ resources & ISRs based on devicetree node compatible entries. This is because new LGM SoC supports single IRQ for all tx/rx/err interrupts while older SoCs support three separate IRQs for tx/rx/err interrupts.
Patch 3 adds LGM SoC specific IRQ/ISR support.
v2:
* Address review concerns.
* Separate dt binding document from this patch series. Will try to push it separately by first converting existing txt file to YAML and then add new properties.
* Omit resending one patch in this series which is already reviewed & added to tty-next.
