Chen-Yu Tsai de2a3eaea5 nvmem: sunxi_sid: Optimize register read-out method ... SID cells are 32-bit aligned, and a multiple of 32 bits in length. The only outlier is the thermal sensor calibration data, which is 16 bits per sensor. However a whole 64 bits is allocated for this purpose, so we could consider it conforming to the rule above. Also, the register read-out method assumes native endian, unlike the direct MMIO method, which assumes big endian. Thus no endian conversion is involved. Under these assumptions, the register read-out method can be slightly optimized. Instead of reading one word then discarding 3 bytes, read the whole word directly into the buffer. However, for reads under 4 bytes or trailing bytes, we still use a scratch buffer to extract the requested bytes. We could go one step further if .word_size was 4, but changing that would affect the sysfs interface's behavior.
