[RFC 0/1] ARM: print MHz in /proc/cpuinfo

2016-06-07 Thread Jon Mason
Many users (and some applications) are expecting the CPU clock speed to be output in /proc/cpuinfo (as is done in x86, avr32, c6x, tile, parisc, ia64, and xtensa). This can be trivially added by simply querying the clock described in the CPU node of the device tree. It appears that many of the DT
