atmel_tc library
Create <linux/atmel_tc.h> based on <asm-arm/arch-at91/at91-tc.h> and the
at91sam9263 and at32ap7000 datasheets. Most AT91 and AT32 SOCs have one
or two of these TC blocks, which include three 16-bit timers that can be
interconnected in various ways.
These TC blocks can be used for external interfacing (such as PWM and
measurement), or used as somewhat quirky sixteen-bit timers.
Changes relative to the original version:
* Drop unneeded inclusion of <linux/mutex.h>
* Support an arbitrary number of TC blocks
* Return a struct with information about a TC block from
atmel_tc_alloc() instead of using a combination of return values
and "out" parameters.
* ioremap() the I/O registers on allocation
* Look up clocks and irqs for all channels
* Add "name" parameter to atmel_tc_alloc() and use this when
requesting the iomem resource.
* Check if the platform provided the necessary resources at probe()
time instead of when the TCB is allocated.
