* ------------------
* The PWM region contains Doorbell Pages. The first is reserverd for

* trusted applications, typically from user space. Each page, called a
* doorbell page is sectioned into windows that allow doorbells to be
* issued in parallel by the kernel/application. The size of such a
* window (a.k.a. WID) is 1kB.
* Summary:
* 1kB WID x N WIDS = DPI page size
* DPI page size x N DPIs = PWM region size
* Notes:
* The size of the DPI page size must be in multiples of OSAL_PAGE_SIZE
* in order to ensure that two applications won't share the same page.
* It also must contain at least one WID per CPU to allow parallelism.
* It also must be a power of 2, since it is stored as a bit shift.
*
* The DPI page size is stored in a register as 'dpi_bit_shift' so that
* 0 is 4kB, 1 is 8kB and etc. Hence the minimum size is 4,096
* containing 4 WIDs.
