A series patches to address three issues one customer managed to hit all at once. 1) Rewrite pericom_do_set_divisor() to always calc divisor and to use the uartclk instead of a hard coded value. Always calculate divisor without passing control to serial8250_do_set_divisor() Tested with 14.7456 and 24 MHz crystals 2) Re-enable higher baud rates on Pericom chips. serial8250_get_baud_rate() added range checking, but Pericom chips have a wider range than what is being enforced. Make use of UPF_MAGIC_MULTIPLIER. Tested with 14.7456 and 24 MHz crystals 3) Fourth port not being setup correctly on some Pericom chips. Fix entries in pci_serial_quirks array Jay Dolan (3): serial: 8250_pci: rewrite pericom_do_set_divisor serial: 8250_pci: Re-enable higher baud rates on Pericom chips serial: 8250_pci: Fix ACCES entries in pci_serial_quirks array drivers/tty/serial/8250/8250_pci.c | 44 +++++++++++++++++++++--------- 1 file changed, 31 insertions(+), 13 deletions(-) -- 2.25.1
