8250/16?50: Add support for Broadcom TruManage redirected serial port

2013-01-21T19:44:46+00:00

commit ebebd49a8eab5e9aa1b1f8f1614ccc3c2120f886 upstream.

Add support for the UART device present in Broadcom TruManage capable
NetXtreme chips (ie: 5761m 5762, and 5725).

This implementation has a hidden transmit FIFO, so running in single-byte
interrupt mode results in too many interrupts.  The UART_CAP_HFIFO
capability was added to track this.  It continues to reload the THR as long
as the THRE and TSRE bits are set in the LSR up to a specified limit (1024
is used here).

serial/8250_hp300: Missing 8250 register interface conversion bits

2012-10-15T20:26:14+00:00

commit 2655a2c76f80d91da34faa8f4e114d1793435ed3 ("8250: use the 8250
register interface not the legacy one") forgot to fully switch one
instance of struct uart_port to struct uart_8250_port, causing the
following compile failure:

drivers/tty/serial/8250/8250_hp300.c: In function ‘hpdca_init_one’:
drivers/tty/serial/8250/8250_hp300.c:174: error: ‘uart’ undeclared (first use in this function)
drivers/tty/serial/8250/8250_hp300.c:174: error: (Each undeclared identifier is reported only once
drivers/tty/serial/8250/8250_hp300.c:174: error: for each function it appears in.)

This went unnoticed in -next, as CONFIG_HPDCA is not set to y by
allmodconfig.

Pull TTY changes from Greg Kroah-Hartman:
 "As we skipped the merge window for 3.6-rc1 for the tty tree,
  everything is now settled down and working properly, so we are ready
  for 3.7-rc1.  Here's the patchset, it's big, but the large changes are
  removing a firmware file and adding a staging tty driver (it depended
  on the tty core changes, so it's going through this tree instead of
  the staging tree.)

  All of these patches have been in the linux-next tree for a while.

serial: set correct baud_base for EXSYS EX-41092 Dual 16950

2012-09-26T20:35:12+00:00

Apparently the same card model has two IDs, so this patch
complements the commit 39aced68d664291db3324d0fcf0985ab5626aac2
adding the missing one.

8250: blacklist Winbond CIR port

2012-09-26T20:25:41+00:00

The legacy serial driver will detect the Winbond CIR device as a serial
port, since it looks exactly like a serial port unless you know what
it is from the PNP ID.

Here we track this port as a special PORT_8250_CIR type, preventing the
legacy serial driver from probing it.

8250_pnp: do pnp probe before legacy probe

2012-09-26T20:25:41+00:00

We first probe the legacy serial ports and then check pnp. If there
is a non-standard configuration then this might not work, also this
change is needed so we can blacklist Winbond CIR based on PNP ID.

For this to work the 8250_pnp driver must be merged into the 8250
module.

The autoconfig prints messages while holding the

These workarounds do not apply for CONFIG_ARCH_OMAP2PLUS at all,
so let's make it just CONFIG_ARCH_OMAP1.

This is needed to for ARM common zImage changes for
