This patch series improves the UART performance in PCI1XXXX from C0 rev using burst mode operation. Each transaction processes DWORDs at a time and the remaining bytes are handled byte-by-byte. With burst mode access the baud rate support is extended from 1.5 Mbps to 3.9 Mbps. v1 Initial Submission for review Rengarajan S (4): 8250: microchip: pci1xxxx: Rearranging the structure declarations 8250: microchip: pci1xxxx: Add Syslock support for reading UART system registers 8250: microchip: pci1xxxx: Add Burst mode reception support in uart driver for writing into FIFO 8250: microchip: pci1xxxx: Add Burst mode transmission support in uart driver for reading from FIFO drivers/tty/serial/8250/8250_pci1xxxx.c | 313 ++++++++++++++++++++++-- 1 file changed, 299 insertions(+), 14 deletions(-) -- 2.25.1
