The Timer/PWM Module (TPM) supports input capture, output compare,
and the generation of PWM signals to control electric motor and power
management applications. The counter, compare and capture registers
are clocked by an asynchronous clock that can remain enabled in low
power modes. TPM can support global counter bus where one TPM drives
the counter bus for the others, provided bit width is the same.
This patch only adds the timer support. PWM would be added later.
ChangeLog:
v1->v2:
* change to readl/writel from __raw_readl/writel according to Arnd's
suggestion to avoid endian issue
* add help information in Kconfig
* add more error checking
