I was looking for the patch that adds the DT data to the soc dts file... Somehow I thought it's in this series. Tomi
This is intended to be the last patch series. I'll apply these trough drm-misc-next tomorrow. Changes since v8: - "dt-bindings: display: ti,k2g-dss: Add dt-schema yaml binding" - Remove ports-node from the dts example in - "drm/tidss: New driver for TI Keystone platform Display SubSystem" - Rename dispc_write_irqenable() to dispc_set_irqenable() to avoid conflict exported omapfb function with same name. - Add Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> - "MAINTAINERS: add entry for tidss" - Add Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Changes since v7: - "drm/tidss: New driver for TI Keystone platform Display SubSystem" - Remove idle debug prints from dispc_init() - Add Reviewed-by: Benoit Parrot <bparrot@ti.com> - "MAINTAINERS: add entry for tidss" - Add Reviewed-by: Benoit Parrot <bparrot@ti.com> Changes since v6: - Rebase on top of drm-misc-next-2020-01-10 - Fix all checkpatch.pl -q --emacs --strict --show-types issues - all issues but these have been fixed: - over 80 char lines in scale coefficients found in tidss_scale_coefs.c - Co-developed-by and Signed-off-by: name/email do not match - added, moved or deleted file(s), does MAINTAINERS need updating - Add Acked-by: Sam Ravnborg <sam@ravnborg.org> to "drm/tidss: New driver ..." Changes since v5: - Add Add Reviewed-by: from Rob Herring <robh@kernel.org> and Benoit Parrot <bparrot@ti.com> to binding patches - Color property changes and fixes to the driver implementation patch - Check CTM and gamma support from dispc_features when creating crtc - Implement CTM support for k2g and fix k3 CTM implementation - Remove gamma property persistence and always write color properties in a new modeset Changes since v4: - itemize named resource property descriptions in dt binding - fix wp to wb in the ti,j721e-dss reg property description - remove fifo underflow irq handling, it is not an error and it should be used for debug purposes only - memory tuning, prefetch plane fifo up to high-threshold value to minimize possibility of underflows. Changes since v3: - Add descriptions some yaml binding properites - Remove redundant minItems directives from yaml bindings - Remove ports node from ti,k2g-dss yaml binding - no change to MAINTAINERS or to the driver code Changes since v2: - Add version history to commit messages - Fix yaml bindings now that got dt_binding_check dtbs_check working property - Move tidss entry in MAINTAINERS after omapdrm and add "T: git git://anongit.freedesktop.org/drm/drm-misc" - no change to driver code Changes since the first version of the patch series [2]: - "drm/tidss: New driver for TI Keystone platform Display SubSystem" - rebased on top of drm-next-2019-11-27 - sort all include lines in all files - remove all include <drm/drmP.h> - remove select "select VIDEOMODE_HELPERS" - call dispc_vp_setup() later in tidss_crtc_atomic_flush() (there is no to call it in new modeset case as it is also called in vp_enable()) - change probe sequence and drm_device allocation (follow example in drm_drv.c) - use __maybe_unused instead of #ifdef for pm functions - remove "struct drm_fbdev_cma *fbdev;" from driver data - check panel connector type before connecting it - No change to binding or MAINTAINERS patches There was couple of attempts upstream an earlier version of this driver about a year ago [1]. Back then I needed to stop my efforts to implement support for next Keystone DSS version, so now the driver supports three different Keystone DSS version on three different SoCs. I am starting the patch series versioning from the beginning because it has been over a year since the previous patch set and the structure of the driver has evolved quite a bit. However, all the earlier comments should be addressed in this series.
