2007-05-07	serial: define FIXED_PORT flag for serial_core	David Gibson	1	-1/+2
	At present, the serial core always allows setserial in userspace to change the port address, irq and base clock of any serial port. That makes sense for legacy ISA ports, but not for (say) embedded ns16550 compatible serial ports at peculiar addresses. In these cases, the kernel code configuring the ports must know exactly where they are, and their clocking arrangements (which can be unusual on embedded boards). It doesn't make sense for userspace to change these settings. Therefore, this patch defines a UPF_FIXED_PORT flag for the uart_port structure. If this flag is set when the serial port is configured, any attempts to alter the port's type, io address, irq or base clock with setserial are ignored. In addition this patch uses the new flag for on-chip serial ports probed in arch/powerpc/kernel/legacy_serial.c, and for other hard-wired serial ports probed by drivers/serial/of_serial.c.

2007-05-02	[POWERPC] Rename get_property to of_get_property: drivers	Stephen Rothwell	1	-2/+2
	These are all the remaining instances of get_property. Simple rename of get_property to of_get_property. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-02-14	[POWERPC] Open Firmware serial port driver	Arnd Bergmann	1	-0/+143
	This can be used for serial ports that are connected to an OF platform bus but are not autodetected by the lecacy serial support. It will automatically take over devices that come from the legacy serial detection, which usually is only one device. In some cases, rtas may be set up to use the serial port in the firmware, which allows easier debugging before probing the serial ports. In this case, the "used-by-rtas" property must be set by the firmware. This patch also adds code to the legacy serial driver to check for this.
