remoteproc: st_slim_rproc: add a slimcore rproc driver
slim core is used as a basis for many IPs in the STi chipsets such as fdma and demux. To avoid duplicating the elf loading code in each device driver a slim rproc driver has been created. This driver is designed to be used by other device drivers such as fdma, or demux whose IP is based around a slim core. The device driver can call slim_rproc_alloc() to allocate a slim rproc and slim_rproc_put() when finished. This driver takes care of ioremapping the slim registers (dmem, imem, slimcore, peripherals), whose offsets and sizes can change between IP's. It also obtains and enables any clocks used by the device. This approach avoids having a double mapping of the registers as slim_rproc does not register its own platform device. It also maps well to device tree abstraction as it allows us to have one dt node for the whole device. All of the generic rproc elf loading code can be reused, and we provide start() stop() hooks to start and stop the slim core once the firmware has been loaded. This has been tested successfully with fdma driver. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
