2016-11-23soc/qman: Drop unused field from eqcr/dqrr descriptorsClaudiu Manoil
ORP ("Order Restoration Point") mechanism not supported. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>
2016-11-23soc/qman: Fix accesses to fqid, cleanupClaudiu Manoil
Preventively mask every access to the 'fqid' h/w field, since it is defined as a 24-bit field, for every h/w descriptor. Add generic accessors for this field to ensure correct access. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>
2016-11-23soc/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.

2016-11-23soc/qman: Remove redundant checks from qman_create_cgr()Claudiu Manoil
opts is checked redundantly. Move local_opts declaration inside its usage scope. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>
2016-11-23soc/qman: test: Don't use dummy platform device for dma mappingClaudiu Manoil
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>
2016-11-23soc/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>
2016-11-23soc/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.

2016-11-23soc/qman: Fix direct access to fd's addr_lo, use proper accesorClaudiu Manoil
Use the proper accessor to get the FD address. Accessing the internal field "addr_lo" directly is not portable and error prone. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>
2016-11-23soc/qbman: Fix resource leak on portal probing error pathClaudiu Manoil
In case init_pcfg() returns with error the CI region must be unmapped too. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>
2016-11-23soc/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).

2016-11-23soc/qman: Replace of_get_property() with portable equivalentMadalin Bucur
Use arch portable of_property_read_u32() instead, which takes care of endianness conversions. Signed-off-by: Madalin Bucur <madalin.bucur@nxp.com> Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>

2016-11-22soc/fsl: fix spelling mistakes in critical error messagesColin Ian King
Trivial fix to spelling mistake "uncommited" to "uncommitted" in critical error messages. Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Scott Wood <oss@buserror.net>
2016-09-25soc/qman: Add self-test for QMan driverClaudiu Manoil
Add self tests for the DPAA 1.x Queue Manager driver. The tests ensure that the driver can properly enqueue and dequeue to/from frame queues using the QMan portal infrastructure.

2016-09-25soc/bman: Add self-test for BMan driverClaudiu Manoil
Add a self test for the DPAA 1.x Buffer Manager driver. This test ensures that the driver can properly acquire and release buffers using the BMan portal infrastructure.

2016-09-25soc/fsl: Introduce DPAA 1.x QMan device driverClaudiu Manoil
This driver enables the Freescale DPAA 1.x Queue Manager block. QMan is a hardware accelerator that manages frame queues. It allows CPUs and other accelerators connected to the SoC datapath to enqueue and dequeue ethernet frames, thus providing the infrastructure for data exchange among CPUs and datapath accelerators.

2016-09-25soc/fsl: Introduce DPAA 1.x BMan device driverClaudiu Manoil
This driver enables the Freescale DPAA 1.x Buffer Manager block. BMan is a hardware accelerator that manages buffer pools. It allows CPUs and other accelerators connected to the SoC datapath to acquire and release buffers during data processing.
