> 
> 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:
> v3->v4:

> v2->v3:
>  * address a few minor comments from Daniel Lezcano
>  * add more explaination on ETIME check in commit message
> 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
