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 Michal Simek (9): serial: uartps: console_setup() can't be placed to init section serial: uartps: Do not initialize field to zero again serial: uartps: Do not use static struct uart_driver out of probe() serial: uartps: Move alias reading higher in probe() serial: uartps: Move register to probe based on run time detection serial: uartps: Fill struct uart_driver in probe() serial: uartps: Change logic how console_port is setup serial: uartps: Register own uart console and driver structures serial: uartps: Move Port ID to device data structure Nava kishore Manne (1): serial: uartps: Fix suspend functionality drivers/tty/serial/xilinx_uartps.c | 203 +++++++++++++++++++------------------ 1 file changed, 107 insertions(+), 96 deletions(-) -- 1.9.1
