Move layer mixer-specific section of dpu_crtc_get_crc() into a separate helper method. This way, we can make it easier to get CRCs from other HW blocks by adding other get_crc helper methods. Changes since V1: - Move common bitmasks to dpu_hw_util.h - Move common CRC methods to dpu_hw_util.c - Update copyrights - Change crcs array to a dynamically allocated array and added it as a member of crtc_state Changes since V2: - Put changes for hw_util into a separate commit - Revert crcs array to a static array - Add else case for set_crc_source to return EINVAL if no valid source is selected - Add DPU_CRTC_MAX_CRC_ENTRIES macro Changes since V3: - Move crcs array into dpu_crtc_get_lm_crc - Remove comment about crcs array in dpu_crtc_state struct - Revert `lm` rename - Remove DPU_CRTC_MAX_CRC_ENTRIES macro - Return EINVAL in dpu_crtc_get_crc if no valid CRC source is set Signed-off-by: Jessica Zhang <quic_jesszhan@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/490735/ Link: https://lore.kernel.org/r/20220622171835.7558-2-quic_jesszhan@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
