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. The first 5 patches are preparation patches to have the last patch as small as possible to focus on changes there. Cases without DT aliases are not solved in this series but one function was shared in RFC v1. The purpose of this series to get feedback on solution where every driver instance allocate at run time own uart_driver. For example this is how it works. uart0 on higher alias serial0 = &uart1; serial100 = &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/ttyPS100 Thanks, Michal Changes in v2: - new patch - it can be sent separately too - Remove nr field logic - new patch - it can be sent separately too - new patch - it can be sent separately too - new patch - it can be sent separately too - Register one uart_driver with unique minor at probe time Michal Simek (6): serial: uartps: Do not initialize field to zero again serial: uartps: Move register to probe based on run time detection serial: uartps: Do not use static struct uart_driver out of probe() serial: uartps: Move alias reading higher in probe() serial: uartps: Fill struct uart_driver in probe() serial: uartps: Remove CDNS_UART_NR_PORTS macro drivers/tty/serial/xilinx_uartps.c | 126 ++++++++++++++++++++----------------- 1 file changed, 68 insertions(+), 58 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
