Flush mechanism for DSPP blocks has changed in sc7280 family, it allows individual sub blocks to be flushed in coordination with master flush control. Representation: master_flush && (PCC_flush | IGC_flush .. etc ) This change adds necessary support for the above design. Changes in v1: - Few nits (Doug, Dmitry) - Restrict sub-block flush programming to dpu_hw_ctl file (Dmitry) Changes in v2: - Move the address offset to flush macro (Dmitry) - Separate ops for the sub block flush (Dmitry) Changes in v3: - Reuse the DPU_DSPP_xx enum instead of a new one (Dmitry) Changes in v4: - Use shorter version for unsigned int (Stephen) Changes in v5: - Spurious patch please ignore. Changes in v6: - Add SOB tag (Doug, Dmitry) Changes in v7: - Cache flush mask per dspp (Dmitry) - Few nits (Marijn) Changes in v8: - Few nits (Marijn) Changes in v9: - Use DSPP enum while accessing flush mask to make it readable (Dmitry) - Few nits (Dmitry) Changes in v10: - Fix white spaces in a separate patch (Dmitry) Changes in v11: - Define a macro for dspp flush selection (Marijn) - Few nits (Marijn) Changes in v12: - Minor comments (reorder macros and a condition) (Marijn) Signed-off-by: Kalyan Thota <quic_kalyant@quicinc.com> Tested-by: Douglas Anderson <dianders@chromium.org> Patchwork: https://patchwork.freedesktop.org/patch/520701/ Link: https://lore.kernel.org/r/1674814487-2112-1-git-send-email-quic_kalyant@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.
