GPIO pin interrupt IRQ's #7

Open Zodiac-69 opened 11 years ago

Zodiac-69 commented 11 years ago

Every GPIO pin can generate an interrupt with number 40 + GPIO pin number. But the init code set the max value to 48 - irq.h - "#define NR_IRQS 48" Thus GPIO(1) to GPIO(8) only.

Please increase this to at least 54, this will give us IRQ's for all the GPIO's available to us.

I will take a look at this once I am done with OpenWRT upstream merging (2 month schedule, #6)

I see that in "carambola-master\target\linux\ramips\files\arch\mips\include\asm\mach-ralink\rt305x\irq.h" the number of IRQ's is still only 8 - #define NR_IRQS 48

No plan to increase this to the full 14 I/O's that are available to us?
