drivers: of: add automated assignment of reserved regions to client devices
This patch adds code for automated assignment of reserved memory regions to struct device. reserved_mem->ops->device_init()/device_cleanup() callbacks are called to perform reserved memory driver specific initialization and cleanup Based on previous code provided by Josh Cartwright <joshc@codeaurora.org> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Grant Likely <grant.likely@linaro.org>
