Could you think about different access widths, please? Not all buses are 32-bits wide and even on 64-bit CPUs one might have 16-bit bus and 32 bits accesses are not allowed or perform two accesses, etc... So to cover the use-cases which I see one needs to have a possibility to select between __raw_writeb()/__raw_writew()/__raw_writel()/__raw_writeq() (now that I'm thinking about it, I think these native-Endianness functions are preferred and if one has a bus with different Endianness he should think about the conversion in the reg property of subnodes). Very important is readback with corresponding __raw_read*(), but maybe you want to do this optional via additional DT property... -- Best regards, Alexander Sverdlin. -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
