Subject[PATCH v3 00/10] serial: uartps: Add run time support for more IPs than hardcoded 2
Date
Hi,

this series is trying to address discussion I had with Alan in past
https://patchwork.kernel.org/patch/9738445/ and also with Rob in v1
https://lkml.org/lkml/2018/4/26/551.

These patches are doing preparation to enable dynamic ID port allocation
which is capable to create devices with higher IDs.

For example this is how it works.
uart0 on higher alias
serial0 = &uart1;
serial30 = &uart0;

~# ls -la /dev/ttyPS*
crw------- 1 root root 252, 0 Jun 6 12:19 /dev/ttyPS0
crw--w---- 1 root root 253, 100 Jan 1 1970 /dev/ttyPS30

Thanks,
Michal

Changes in v3:
- New patch found by testing
- New patch - can be sent separately but there is dependency that's why
sent in this series
- Fix uart_unregister_driver() in error path or when driver is removed.
- Change commit message
- s/,/;/ in filling structure
- get cdns_uart_uart_driver out of PS_UART_CONSOLE ifdefs
- New patch in series
- Rebase on the top of previous broken patch
- Change patch subject ("was serial: uartps: Remove CDNS_UART_NR_PORTS
macro")
- Keep CDNS_UART_NR_PORTS in this patch and remove it in next one and
align commit message to reflect this
- Allocate struct console dynamically too to be unique for every
instance
- Cleanup error path
- New patch in series

Changes in v2:
- new patch - it can be sent separately too
- new patch - it can be sent separately too
- new patch - it can be sent separately too
- Remove nr field logic
- new patch - it can be sent separately too
- Register one uart_driver with unique minor at probe time
