2019-10-31bus: fsl-mc: add the fsl_mc_get_endpoint functionIoana Ciornei1-0/+53
Using the newly added fsl_mc_get_endpoint function a fsl-mc driver can find its associated endpoint (another object at the other link of a MC firmware link). The API will be used in the following patch in order to discover the connected DPMAC object of a DPNI. Also, the fsl_mc_device_lookup function is made available to the entire fsl-mc bus driver and not just for the dprc driver.

2019-05-20bus: mc-bus: Add support for mapping shareable portalsRoy Pledge1-3/+27
Starting with v5 of NXP QBMan devices the hardware supports using regular cacheable/shareable memory as the backing store for the portals. This patch adds support for the new portal mode by switching to use the DPRC get object region v2 command which returns both a base address and offset for the portal memory. The new portal region is identified as shareable through the addition of a new flag.

Move the source files out of staging into their final locations: -mc.h include file in drivers/staging/fsl-mc/include go to include/linux/fsl -source files in drivers/staging/fsl-mc/bus go to drivers/bus/fsl-mc -overview.rst, providing an overview of DPAA2, goes to Documentation/networking/dpaa2/overview.rst Update or delete other remaining staging files -- Makefile, Kconfig, TODO. Update dpaa2_eth and dpio staging drivers. Add integration bits for the documentation build system.
