I want to request a peripheral interrupt task use the GPIO PH2,but when I do it like this:

request_irq(IRQ_PH2, My_task,IRQF_TRIGGER_HIGH,DEVICE_NAME,NULL);

a error was happened：

"bfin-gpio: GPIO 34 is already reserved as Peripheral by bfin-spi !

setting trigger mode 4 for irq 105 failed (_bfin_gpio_irq_type+0x0/0x154)

Request the IRQ_PH2 failed!"

how to request it?

you didnt say what version of software or hardware you're using.  going by the names, and assuming you're using BF51x, you need to update your tree to the latest svn to get a fix for the issue.

怎么修改呢？为什么更新后会出现这样的错误？是不是和page_alloc.c这个文件有关系？

Message: 91271    You have both mmc_spi (spi0.5) and bfin-sdh enabled - Is this intended?

Spi0.5 is PORT PG3 as well as bfin-sdh uses PG3 as Data0...

Message: 91289    Looking at your kernel start messages - shows.

bfin-spi bfin-spi.1: Blackfin on-chip SPI Controller Driver, Version 1.0, regs_b

ase@ffc03400, dma channel@5

SPI1 requests SPI1_MISO which is the same pins as GPIO 34.

If you don't need SPI1 (bfin_spi1_device) - remove it from your platform data.

Can I delete those struct direct?like :
