There is lots left to do - in particular resource claim/release should be an ops method, and it's going to need people to update various embedded 8250 drivers when we finally go for a version of it. On the bright side once we have an ops structure we have the basis for avoiding further mayhem in the arch code. --- Alan Cox (5): 8250: extract out the "odd" port types 8250: evict the hub6 I/O operations 8250: register upio users 8250: introduce the idea of an operations struct for an 8250 port 8250: Make serial_dl_write a port operation drivers/char/mwave/mwavedd.c | 2 drivers/tty/serial/8250.c | 450 ++++++++++++++------------------------- drivers/tty/serial/8250.h | 27 ++ drivers/tty/serial/8250_au.c | 90 ++++++++ drivers/tty/serial/8250_dwapb.c | 120 ++++++++++ drivers/tty/serial/8250_hub6.c | 39 +++ drivers/tty/serial/8250_pci.c | 2 drivers/tty/serial/8250_pnp.c | 2 drivers/tty/serial/8250_rm9k.c | 95 ++++++++ drivers/tty/serial/Kconfig | 9 + drivers/tty/serial/Makefile | 3 drivers/tty/serial/of_serial.c | 2 drivers/tty/serial/serial_cs.c | 2 include/linux/serial_8250.h | 36 ++- include/linux/serial_core.h | 5 15 files changed, 579 insertions(+), 305 deletions(-) create mode 100644 drivers/tty/serial/8250_au.c create mode 100644 drivers/tty/serial/8250_dwapb.c create mode 100644 drivers/tty/serial/8250_rm9k.c -- Words without body bare winter barren trees much unspoken
