Disabling the crossbar mux between DSC and PINGPONG currently requires a bogus enum dpu_pingpong value to be passed when calling dsc_bind_pingpong_blk() with enable=false, even though the register value written is independent of the current PINGPONG block. Replace that `bool enable` parameter with a new PINGPONG_NONE dpu_pingpong flag that triggers the write of the "special" 0xF "crossbar disabled" value to the register instead. Changes in v4: -- more details to commit text Changes in v5: -- rewording commit text suggested by Marijn -- add DRM_DEBUG_KMS for DSC unbinding case Changes in v8: -- fix checkpatch warning Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Marijn Suijten <marijn.suijten@somainline.org> Patchwork: https://patchwork.freedesktop.org/patch/539505/ Link: https://lore.kernel.org/r/1685036458-22683-6-git-send-email-quic_khsieh@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.
