cpm_uart: Add generic clock API support to set baudrates

2008-07-28T13:47:32+00:00

This patch introduces baudrate setting support via the generic clock API.
When present the optional device tree clock property is used instead of
fsl-cpm-brg. Platforms can then define complex clock schemes, to output
the serial clock on an external pin for instance.

cpm_uart: Modem control lines support

2008-07-28T12:48:04+00:00

This patch replaces the get_mctrl/set_mctrl stubs with modem control line
read/write access through the GPIO lib.

Available modem control lines are described in the device tree using GPIO
bindings. The driver expect a GPIO pin for each of the CTS, RTS, DCD, DSR,
DTR and RI signals. Unused control lines can be left out.

cpm1: don't send break on TX_STOP, don't interrupt RX/TX when adjusting termios parameters

2008-07-24T17:47:30+00:00

Before setting STOP_TX, set _brkcr to 0 so the SMC does not send a break
character.  The driver appears to properly re-initialize _brkcr when the
SMC is restarted.

Do not interrupt RX/TX when the termios is being adjusted; it results in
corrupted characters appearing on the line.

port_fixups: Fix ups for tty port changes

2008-07-22T20:03:29+00:00

I missed the cpm_uart one. Thanks to Kumar Gala for reporting it. A double
check found samsung also needed fixing up.

cpm_uart: Support uart_wait_until_sent()

2008-07-14T12:55:38+00:00

Set port->fifosize to the software FIFO size, and update the port timeout
when the baud rate is modified. SCC ports have an optional 32 byte hardware
FIFO which is currently not taken into account, as there is no documented way
to check when the FIFO becomes empty.

cpm_uart: Fix cpm uart corruption with PREEMPT_RT

2008-07-14T12:55:29+00:00

Fix CPM serial port corruption when running with CONFIG_PREEMPT_RT.
Userland usage of console, and kernel printf's were stepping on each others toes.
Also only take lock if not in an oops.

cpm_uart: Remove !CONFIG_PPC_CPM_NEW_BINDING code

2008-06-26T06:49:04+00:00

Now that arch/ppc is gone we always define CONFIG_PPC_CPM_NEW_BINDING so
we can remove all the code associated with !CONFIG_PPC_CPM_NEW_BINDING.
