The NXP's QorIQ processors based on ARM Core have RCPM module (Run Control and Power Management), which performs system level tasks associated with power management such as wakeup source control. Note that this driver will not support PowerPC based QorIQ processors, and it depends on PM wakeup source framework which provide collect wake information.

Before this change, unbinding the QMan portals did not trigger a corresponding unbinding of the dpaa_eth making use of it; the first QMan portal related operation issued afterwards crashed the kernel.

Convert docs to ReST and add them to the arch-specific book. The conversion here was trivial, as almost every file there was already using an elegant format close to ReST standard. The changes were mostly to mark literal blocks and add a few missing section title identifiers. One note with regards to "--": on Sphinx, this can't be used to identify a list, as it will format it badly. This can be used, however, to identify a long hyphen - and "---" is an even longer one. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

2019-06-05soc: fsl: qe: fold qe_get_num_of_snums into qe_snums_initRasmus Villemoes1-30/+16
The comment "No QE ever has fewer than 28 SNUMs" is false; e.g. the MPC8309 has 14. The code path returning -EINVAL is also a recipe for instant disaster, since the caller (qe_snums_init) uncritically assigns the return value to the unsigned qe_num_of_snum, and would thus proceed to attempt to copy 4GB from snum_init_46[] to the snum[] array. So fold the handling of the legacy fsl,qe-num-snums into qe_snums_init, and make sure we do not end up using the snum_init_46 array in cases other than the two where we know it makes sense.

Add driver support for the newly introduced fsl,qe-snums property. Conveniently, of_property_read_variable_u8_array does exactly what we need: If the property fsl,qe-snums is found (and has an allowed size), the array of values get copied to snums, and the return value is the number of snums - we cannot assign directly to num_of_snums, since we need to check whether the return value is negative.

The current array of struct qe_snum use 256*4 bytes for just keeping track of the free/used state of each index, and the struct layout means there's another 768 bytes of padding. If we just unzip that structure, the array of snum values just use 256 bytes, while the free/inuse state can be tracked in a 32 byte bitmap. So this reduces the .data footprint by 1760 bytes. It also serves as preparation for introducing another DT binding for specifying the snum values.

Add a couple of new APIs to check the probing status of the required cpu bound qman and bman portals: 'int bman_portals_probed()' and 'int qman_portals_probed()'. They return the following values. * 1 if qman/bman portals were all probed correctly * 0 if qman/bman portals were not yet probed * -1 if probing of qman/bman portals failed Portals are considered successful probed if no error occurred during the probing of any of the portals and if enough portals were probed to have one available for each cpu. The error handling paths were slightly rearranged in order to fit this new functionality without being too intrusive. Drivers that use qman/bman portal driver services are required to use these APIs before calling any functions exported by these drivers or otherwise they will crash the kernel.
