* [SERIAL] mark several serial tables constArjan van de Ven2005-11-28

| * [SERIAL] Fix status reporting with PL011 serial driverRussell King2005-11-19
| | | | | | | | | | | | | | | | | | The receiver status register reports latched error conditions, which must be cleared by writing to it. However, the data register reports unlatched conditions which are associated with the current character. Use the data register to interpret error status rather than the RSR.

* | [PARISC] Define port->timeout to fix a long msleep in mux.cRyan Bradetich2005-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is in response to a bug reported by Vesa on the irc channel a couple of weeks ago. The bug was that the console would apparently hang (not return) while using the mux console. The root cause of this bug is that bash (with readline support) makes a call to the tcsetattr() glibc function with the argument TCSADRAIN. This causes the serial core in the kernel use the uart_wait_until_sent() to be called. This function verifies the mux transmit queue is empty or calls the msleep_interruptable() with a calculated timeout value that is dependant upon the port->timeout variable. The real problem here is that the port->timeout was not defined so it was defaulted to 0 and the timeout calculation performs the following calculation: char_time = (port->timeout - HZ/50) / port->fifosize; where char_time is an unsigned long. Since the serial Mux does not use interrupts, the msleep_interruptable() function waits until the timeout has been reached ... and when the port->timeout < HZ/50 this timeout will be a long time. (I have validated that the console will eventually return ... but it takes quite a while for this to happen). This patch simply sets the port->timeout on the Mux to HZ/50 to avoid this long timeout period.

| * [SERIAL] don't disable xscale serial ports after autoconfigLennert Buytenhek2005-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xscale-type UARTs have an extra bit (UUE) in the IER register that has to be written as 1 to enable the UART. At the end of autoconfig() in drivers/serial/8250.c, the IER register is unconditionally written as zero, which turns off the UART, and makes any subsequent printch() hang the box. Since other 8250-type UARTs don't have this enable bit and are thus always 'enabled' in this sense, it can't hurt to enable xscale-type serial ports all the time as well. The attached patch changes the autoconfig() exit path to see if the port has an UUE enable bit, and if yes, to write UUE=1 instead of just putting a zero into IER, using the same test as is used at the beginning of serial8250_console_write().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.
