ARM: OMAP4: CPUidle: Make C-state description field more precise (eb495d33) · Commits · 戴 / test

It is useful to know the CPU power state along with MPUSS power state in a supported C-state. Since the data is available via sysfs, one can avoid scrolling the source code for precise construction of C-state. Reported-by:
