Now, our many SoC codes are using 0x4 in "interrupts". Do you think we should use IRQ_TYPE_LEVEL_HIGH ?

Sure, of course. I was actually thinking about sending a patch to convert our DT sources to use the IRQ_* macros. Morimoto-san, are you working on that already ? If not I'll do it. Simon, would you like one patch per SoC or would a single patch do ? Only .dts(i) files will be touched.

I would prefer one patch per SoC. The reason is that in general that approach makes backporting easier. -- To unsubscribe from this list: send the line "unsubscribe linux-sh" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I've already posted the series on Saturday, it's called "[PATCH 0/7] ARM: shmobile: Use interrupt macros in DT files". Could you please have a look ? I can split patches 1/7 to 3/7 in 28 patches and repost if you would like me to, but that sounds like a really high number of patches for something so simple, especially for patch 1/7.
