m68k/irq - Use polled IRQ flag for MFP timer cascaded interrupts

2014-01-13T08:29:10+00:00

Some Atari hardware has no capacity to raise interrupts (e.g. network or USB adapter hardware attached via ROM port). The driver interrupt routine is called from a timer interrupt (timer D) in these cases, using chained device specific pseudo interrupts (IRQ_MFP_TIMER1 ff.) These interrupts will more often than not, return IRQ_NONE as there is not always work for the device handler when called. Too many unhandled interrupts will result in the interrupt being disabled by the stuck interrupt watchdog. As preferred option to flag interrupts as needing exclusion from the watchdog mechanism, tglx added the IRQ_IS_POLLED flag for use in such a case. Currently, two interrupts need to use this flag. Add more users as needed. Signed-off-by: Michael Schmitz Signed-off-by: Geert Uytterhoeven

m68k/atari: EtherNAT - add interrupt chip definition for CPLD interrupts

2013-04-16T19:35:39+00:00

Add a dedicated interrupt chip definition for the EtherNAT CPLD interrupts. SMC91C111 and ISP1160 chips have separate interrupts that can be enabled and disabled in a CPLD register at offset 0x23 from the card base. Note the CPLD interrupt control register is mapped on demand, whenever any interrupt enable/disable action is requested. The EtherNAT USB driver still needs interrupts disabled around reset and start actions. In particular, we cannot entirely rely on the irq_startup being called first. The smc91x and isp116x-hcd drivers will use this feature. Signed-off-by: Michael Schmitz Signed-off-by: Geert Uytterhoeven

m68k/atari: use dedicated irq_chip for timer D interrupts

2013-04-16T19:09:21+00:00

Add a special irq_chip for the Atari MFP timer D interrupt, which is used as a polling timer for EtherNEC and NetUSBee Signed-off-by: Michael Schmitz Signed-off-by: Geert Uytterhoeven

m68k/atari: Change VME irq numbers from unsigned long to unsigned int

2012-04-22T18:16:49+00:00

Device interrupts numbers were changed to unsigned int in 1997, the year IRQ_MACHSPEC was killed as well. Also kill a related cast while we're at it. Signed-off-by: Geert Uytterhoeven Cc: netdev@vger.kernel.org

m68k/irq: Remove obsolete support for user vector interrupt fixups

2011-11-08T21:35:52+00:00

It was used on Apollo only, before its conversion to genirq. Signed-off-by: Geert Uytterhoeven

m68k/atari: Remove code and comments about different irq types

2011-11-08T21:35:49+00:00

This code was obsoleted during the irq restructuring in 2006. Signed-off-by: Geert Uytterhoeven

m68k/irq: Add m68k_setup_irq_controller()

2011-11-08T21:35:48+00:00

This is a wrapper around m68k_setup_irq_chip() that discards its dummy second parameter, to ease the future transition to genirq. Signed-off-by: Geert Uytterhoeven
