The git branch bellow is updated. Changes since v2: - Add: "drm/tilcdc: Fix load mode bit-field setting in tilcdc_crtc_enable()" - Drop: "drm/tilcdc: Free palette dma memory in tilcdc_crtc_destroy()" - Add: "drm/tilcdc: Add timeout wait for palette loading to complete" - Add: "drm/tilcdc: Call reset() before loading the palette" - Add: "drm/tilcdc: Use complete_all() to indicate completed palette loading" - Add "drm/tilcdc: Enable frame done irq and functionality for LCDC rev 1" - Bartosz: Please test if this works! The symptom for not working is "timeout waiting for framedone" message when screen is blanked. Changes since first version of the series: - Move tilcdc_regs.h changes from "drm/tilcdc: Enable palette loading for revision 2 LCDC too" to "drm/tilcdc: Add tilcdc_write_mask() to tilcdc_regs.h" These patches are inspired by this series form Bartosz Golaszewski: https://www.spinics.net/lists/arm-kernel/msg539629.html The patches are based on drm-next plus the earlier patches that I plan to send in a pull request for 4.10. The base + these patches are pushed here: https://github.com/jsarha/linux drm-next-tilcdc-for-4.10-wip Bartosz, please test if this branch works for rev1 LCDC, with your dts file!
