2006-01-06[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ↵Dominik Brodowski1-50/+8
callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2006-01-06[PATCH] pcmcia: remove dev_list from driversDominik Brodowski1-15/+2
The linked list of devices managed by each PCMCIA driver is, in very most cases, unused. Therefore, remove it from many drivers. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2006-01-06[PATCH] pcmcia: unify detach, REMOVAL_EVENT handlers into one remove callbackDominik Brodowski1-14/+5
Unify the "detach" and REMOVAL_EVENT handlers to one "remove" function. Old functionality is preserved, for the moment. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2006-01-06[PATCH] pcmcia: new suspend coreDominik Brodowski1-21/+10
Move the suspend and resume methods out of the event handler, and into special functions. Also use these functions for pre- and post-reset, as almost all drivers already do, and the remaining ones can easily be converted.

2005-11-18[PARISC] Define port->timeout to fix a long msleep in mux.cRyan Bradetich1-0/+7
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.

2005-11-13[SERIAL] don't disable xscale serial ports after autoconfigLennert Buytenhek1-1/+4
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().

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King7-37/+24
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.
