media: rppx1: Add framework to support Dreamchip RPPX1 ISPAdd a framework driver for Dreamchip RPPX1 ISP. The driver aims toprovide a framework for other V4L2 based drivers to drive the RPPX1functionality. The reason for this split is that the RPPX1 IP itself donot provide any DMA engines to drive data to/from the device, instead itdepends on other IP blocks to implement these features.While the peripherals around the RPPX1 ISP used in different designs andby different vendors are different the RPPX1 core itself is the same.For this reason the framework solution to be able to split the DreamchipRPPX1 driver from vendors usage of it have been picked in hope to reduceduplication of the common parts.The design is to try and keep the surface of this framework as small aspossible. The intention of this change is to be able to fill all needsof this. * Two functions to create and destroy a RPPX1 instance, rppx1_create() and rppx1_destory(). These are intended to be called in the users probe and remove code paths. * Two functions to start and stop the RPPX1 processing, rppx1_start() and rppx1_stop(). These are intended to be called in the users stream on and stream off code paths. * One function to ask the RPPX1 to process parameters buffer prepared by user space, rppx1_params(). The intention is to call this function when the parameter buffer is queued to the V4L2 driver and the result stored by the driver until the time it needs to be written to the RPPX1. It's the users responsibility to write it either using MMIO or other means. * One function to fill in a statistic buffer based on the current status of the RPPX1, rppx1_stats_fill_isr(). The intention is that the user call's this in its interrupt handler when it knows the RPPX1 is done processing a frame. * One function to ack and retrieve the interrupts generated by the RPPX1, rppx1_interrupt(). The intention is to call this function when the users interrupt handler detects the RPPX1 have raised and interrupt. There is no need for the user to understand, or act, on the actual RPPX1 interrupt, but it can if it wants too.The initial support in the framework is limited and do not implement anyISP processing algorithms other then configuring the RPPX1 to processany Bayer (8-, 10, or 12-bit) image and produce either a RGB or YUYVoutput. It do however probe all function blocks of the RPPX1 and providean interface to interact with both parameter and statistic bufferers.The user of the framework will not change as algorithms for thedifferent function blocks of the ISP are being added.Signed-off-by: Niklas Söderlund Co-developed-by: Jai Luthra Signed-off-by: Jai Luthra Co-developed-by: Jacopo Mondi Signed-off-by: Jacopo Mondi Reviewed-by: Jacopo Mondi Signed-off-by: Sakari Ailus List of files: /linux/drivers/media/platform/dreamchip/Makefile
