What exactly do you mean by interrupt multiplexing?
Oh, It is mean u-boot providing an interrupt management to manage lots of interrupts from the device. Like linux kernel. So forgive me for asking such unclearly question make you confused.
interrupt handler for my specific device.
Why not? What's wrong with using install_hdlr() / free_hdlr() ?
Having said this, I should ask: why do you think you must use interrupts in the first place?
Actually, I usually using interrupts for device driver. As in u-boot, I am not realize interrupt is not necessary.
Is there any mechanism to inplement the same function?Using polling method and make a fake interrupt?
Normally you don't need interrupts in U-Boot. U-Boot is strictly single-tasking by nature and design. So you can just use polling in your device driver.
Ok, Thanks for you help. I will try to using the polling method to inplement the device driver.
Best Regards. Thanks a lot
