2017-12-12soc/qbman: Disable IRQs for deferred QBMan workRoy Pledge
Work for Congestion State Notifications (CSCN) and Message Ring (MR) handling is handled via the workqueue mechanism. This requires the driver to disable those IRQs before scheduling the work and re-enabling it once the work is completed so that the interrupt doesn't continually fire.

2017-12-12soc/qman: Remove unused struct qm_mcc* layoutsClaudiu Manoil
1. qm_mcc_querywq layout not used for now, so drop it; 2. queryfq, queryfq_np and alterfq are used only for accesses to the 'fqid' field, so replace these with a generic 'fq' layout. As a consequence, 'querycgr' turns into 'cgr' following the same reasoning above and for consistent naming.

Replace dummy platform device hack with a reference to a portal's platform device, in order to dma map the test frame for this small unit test. The 2 qman symbols need to be exported because this self test is a kernel module. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>
2017-12-12soc/qman: Don't add a new platform device for dma mappingClaudiu Manoil
The qman portals are platform devices themselves, so they should handle dma mappings. Creating a dummy platform device in order to support dma mapping operations is not justified (and not portable). Instead, do the mapping against the first portal that has been initialised. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>
2017-12-12soc/qman: test: Fix implementation of fd_cmp()Claudiu Manoil
This function must only return the truth value of whether two frame descriptors are different or not. It does NOT have to compute some obscure difference between fd fields and return it as an int, making sparse complain about type conversions in the process.

2017-12-12soc/qman: Fix direct access to fd's addr_lo, use proper accesorClaudiu Manoil

2017-12-12soc/qman: Fix h/w resource cleanup error path handlingClaudiu Manoil
qman_query_fq*() may return other error codes apart from -ERANGE, in which cases the error handling done by the resource cleanup callers would be wrong. The patch fixes the handling of those cases, and cleans up related code inside the resource cleanup & release handlers (i.e. replace hardcoded fqid value with corresponding define).

2017-07-14Fix errata A-007728 for flextimerMeng Yi
If the FTM counter reaches the FTM_MOD value between the reading of the TOF bit and the writing of 0 to the TOF bit, the process of clearing the TOF bit does not work as expected when FTMx_CONF[NUMTOF] != 0 and the current TOF count is less than FTMx_CONF[NUMTOF]. If the above condition is met, the TOF bit remains set. If the TOF interrupt is enabled (FTMx_SC[TOIE] = 1), the TOF interrupt also remains asserted. Above is the errata discription In one word: software clearing TOF bit not works when FTMx_CONF[NUMTOF] was seted as nonzero and FTM counter reaches the FTM_MOD value. The workaround is clearing TOF bit until it works(FTM counter doesn't always reache the FTM_MOD anyway),which may cost some cycles. Signed-off-by: Meng Yi <meng.yi@nxp.com>
