PATCH 1/1 ARM: OMAP1: fix incorrect INT_DMA_LCD

Quoted 6 lines · Aaro Koskinen

Commit 685e2d08c54b ("ARM: OMAP1: Change interrupt numbering for sparse IRQ") turned on SPARSE_IRQ on OMAP1, but forgot to change the number of INT_DMA_LCD. This broke the boot at least on Nokia 770, where the device hangs during framebuffer initialization.
Fix by defining INT_DMA_LCD like the other interrupts.

OK good to hear, applying into omap-for-v4.3/fixes. If it does not get pulled for v4.3, then it's already tagged cc: stable. BTW, you should not send mail to cc stable when posting patches, Greg will send you a note on that.

I'm having hard time booting 770 and n800 after I had to change my motherboard last sring.

Somehow 0xFFFF can't get anything loaded over USB. I even installed a new PCIe OHCI + EHCI adapter but still no luck.

Regards,

Tony
