Some SoC have a 32 bit variant of Timer Counter Blocks. We do not
need the chaining of two 16 bit counters anymore for them.The SoC nature is deduced from the device tree "compatible" string.
For non-device-tree configurations, backward compatibility is maintained
by using the default 16 bit counter configuration.This patch addresses both the atmel_tclib and its user: tcb_clksrc
clocksource.Signed-off-by: Nicolas Ferre

Create based on 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
* 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.Signed-off-by: David Brownell
