Hello everyone, Here's a set of patches that turn the existing SMIA driver into a MIPI CCS driver while maintaining SMIA support. A number of bugs in the existing code are fixed in this set, too. The changes at this point are primarily focused on dealing with new mandatory driver features related to PLL configuration (as CCS allows for much more variation there) and things such as integer conversion from U16.U16 format instead of float. There are some other new features as well such as digital gain and support for getting device specific analogue gain coefficients. A new feature in CCS is CCS static data which makes it possible to obtain sensor's capabilities and limits from a file chosen based on sensor identification. CCS static data is used also for storing MSR registers so supporting new, CCS compliant devices requires no driver changes. Note that the library as well as the register definitions are dual licensed under GNU GPL v2 OR BSD 3-clause licenses for use outside the Linux kernel. Also DT bindings are updated accordingly and converted to YAML format. More information on MIPI CCS can be found here: <URL:https://www.mipi.org/specifications/camera-command-set> Comments are welcome. since v1: - Fix the SPDX tag in mk-ccs-regs script - Add support for producing kernel definitions including use of BIT macro and kernel types in mk-ccs-regs (was C99 only) - Add MAINTAINERS entry for the documentation in the first documentation patch. - Fix compilation issues due to ccs-limits.o missing from Makefile in a few patches early in the set. since the big, big patchset (v2): - Split into more easily reviewable chunks (this is the first of maybe three). The cover page describes the entire big set. This set contains mostly cleanups for the smiapp driver that prepare for support for additional features as well as DT bindings, as well as using CCS limits. - Fix SPDX tags. Some were left accidentally with BSD-3-Clause license only. - Fix bus-type alignment in DT bindings. - Add CCS driver documentation - Add -u option to the CCS register definition generator. - Add static keyword for ccs_limit_offset array. - Add generated CCS register definitions, and do not generate the definitions as part of the build process. - Remove ccs-os.h header.
