| * serial: sh-sci: kgdb console build fixes.Paul Mundt2007-09-211-3/+1
| | | | | | | | | | | | | | | | | | | | | | The kgdb console code requires uart_set_options() and friends, which are only provided by the serial core when console support is enabled. These were sitting under CONFIG_SH_KGDB and resulted in a link error when console support wasn't enabled, work that by rolling the console routines under CONFIG_SH_KGDB_CONSOLE, which they should have been all along.

| * | [POWERPC] cpm: Describe multi-user ram in its own device node.Scott Wood2007-10-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way the current CPM binding describes available multi-user (a.k.a. dual-ported) RAM doesn't work well when there are multiple free regions, and it doesn't work at all if the region doesn't begin at the start of the muram area (as the hardware needs to be programmed with offsets into this area). The latter situation can happen with SMC UARTs on CPM2, as its parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't support moving it. It is now described with a muram node, similar to QE. The current CPM binding is sufficiently recent (i.e. never appeared in an official release) that compatibility with existing device trees is not an issue. The code supporting the new binding is shared between cpm1 and cpm2, rather than remain separated. QE should be able to use this code as well, once minor fixes are made to its device trees.

| * | [POWERPC] cpm_uart: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING ↵Scott Wood2007-10-046-25/+260
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is set. The existing OF glue code was crufty and broken. Rather than fix it, it has been removed, and the serial driver now talks to the device tree directly. The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms are dropped from arch/ppc (which will hopefully be soon), and existing arch/powerpc boards that I wasn't able to test on for this patchset get converted (which should be even sooner).

| | | | | | | | | | | | | | | | | | | | | Reading the LSR clears the break, parity, frame error, and overrun bits in the 8250 chip, but these are not being saved in all places that read the LSR. Same goes for the MSR delta bits. Save the LSR bits off whenever the lsr is read so they can be handled later in the receive routine. Save the MSR bits to be handled in the modem status routine. Also, clear the stored bits and clear the interrupt registers before enabling interrupts, to avoid handling old values of the stored bits in the interrupt routines.

| | | | | | | | | | | | | | | | | | | The uart_set_termios() function will bail out early without bothering to touch the hardware, if it decides that nothing "relevant" has changed. Unfortunately, its idea of "relevant" doesn't include c_[io]speed. So if the baud rate bits are BOTHER and you just change the speed, the change gets optimised away. This patch makes it ignore the old Bfoo bits in c_cflag and just check whether c_ispeed and c_ospeed have changed. Those integers are always set appropriately for us by set_termios().

| | | | | | | | | | the early setup function serial8250_console_early_setup() can be called from non __init code (eg. hotpluggable serial ports like serial_cs) so remove the __init from the call chain to avoid crashes.

* sb1250-duart: __maybe_unused, etc. fixesMaciej W. Rozycki2007-08-011-8/+6
| | | | | | | | | | | | | This is a set of small fixes addressing points raised with the original driver submission. In particular, __maybe_unused is used rather than a local hack and sbd_ops is made const. Additionally I have made two local string variables automatic as rodata space was wasted for pointers unnecessarily. Signed-off-by: Maciej W.
