Subject: [PATCH v3 00/14] serial: liteuart: add IRQ support
Add IRQ support to the LiteX LiteUART serial interface
Changes from v2:
- further split out "separate RX loop from poll timer" into
dedicated patches highlighting additional changes explicitly:
- factoring out tty_flip_buffer_push() (6/14)
- ack only RX events in RX loop (7/14)
- pass constant flag to uart_insert_char() directly (8/14)
- fix variable types in rx loop (9/14)
- separating RX loop from poll timer (10/14)
- added patch (11/14) to move function definitions to a more
convenient location, making subsequent changes easier to read
in diff patch form.
- fixes and clarifications for RX path IRQ support patch (now 12/14):
- only return IRQ_HANDLED for RX events
- use pr_fmt() to improve style of irq setup error message
- remove unnecessary locking from around single-register access
- modify TX path to support both IRQ-mode and polling (13/14)
- move polling-only liteuart_putchar() behind same conditional
(CONFIG_SERIAL_LITEUART_CONSOLE) as the rest of the code that's
still using it.
