This patch set adds a new clocksource driver that uses the OS Timer (OSTM) that exists in the R7S72100 (RZ/A1) SoC. The operation of the driver was tested with a simple user application that does multiple calls to nanosleep() and gettimeofday(). The purpose of adding this driver is to get better time keeping accuracy over the default MTU2 clocksource timer. v2: * The biggest change was now the channels are independent of each other and have separate nodes in the DT. The first probed will be set up as a clock source, and any additional channels probed will become a clock event.
