This patch series adds the driver for the DPIO object which is a
step to addressing the final item in the staging TODO list-- adding
a functional driver on top of the bus driver. The DPIO driver is a
dependency for other functional drivers such as Ethernet.
An overview of the DPIO object and driver components are in patch 1.
Patches 2-6 are internal components of the DPIO driver-- bit twiddling
of hardware registers, DPAA2 data structures, and the queuing APIs exposed
to other drivers.
Patch 7 adds the fsl-mc driver for the DPIO object. It provides
the probe/remove functions, demonstrating a working example of
how fsl-mc drivers initialize, interact with the management
complex hardware, map their mappable MMIO regions, initialize
interrupts, register an ISR, etc. All other DPAA2 drivers will
follow a similar initialization pattern.
version 4 changes
-removed the patch moving the bus driver out of staging, updated
all paths referenced in dpio (e.g. includes) to be drivers/staging
-defined macros for constants where needed
-copyright updates
-cleanup: fixed whitespace, alignment issues, typos, removed unneeded
comments
-fixed bug in SDQCR #define
-adding missing free in an error path
version 3 changes
-zero memory allocated for a dpio store
-replace hardcoded dequeue token with a #define and look for
that token when checking for a new result
version 2 changes (mostly feedback from Ioana Radulescu)
-removed unused structs and defines in dpio command definitions
-added setter/getter for the FD ctrl field
-corrected comment for SG format_offset field description
-added support for short length field in FD
-fix bug in buffer release command, by setting bpid field
-handle error (NULL) return value from qbman_swp_mc_complete()
-fix bug in sending management commands where the verb was
properly initialized
-use service_select_by_cpu() for re-arming DPIO interrupts
-replace use of NR_CPUS with num_possible_cpus()
-handle error case where number of DPIOs exceeds number of possible
CPUs
-error message cleanup
-updated MAINTAINERS file with proper location for both fsl-mc bus
driver and dpio driver
