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).

2016-09-25soc/fsl/qe: fix Oops on CPM1 (and likely CPM2)Christophe Leroy
Commit 0e6e01ff694ee ("CPM/QE: use genalloc to manage CPM/QE muram") has changed the way muram is managed. genalloc uses kmalloc(), hence requires the SLAB to be up and running. On powerpc 8xx, cpm_reset() is called early during startup. cpm_reset() then calls cpm_muram_init() before SLAB is available, hence the following Oops. cpm_reset() cannot be called during initcalls because the CPM is needed for console. This patch removes the call to cpm_muram_init() from cpm_reset(). cpm_muram_init() will be called from a new function called cpm_init() which is declared as subsys_initcall, unless cpm_muram_alloc() is called earlier for the serial console in which case cpm_muram_init() will be called from there. The reason for calling it from two places is that some drivers (e.g. i2c-cpm) need some of the initialisations done by cpm_muram_init() but don't call cpm_muram_alloc(). The console driver calls cpm_muram_alloc() but some platforms might not use the CPM serial ports for console.
