[PATCH v8 0/7] Support DRM bridges on NVIDIA Tegra
by Dmitry Osipenko 30 Jun '20

30 Jun '20

Hello, This series adds initial support for the DRM bridges to NVIDIA Tegra DRM driver. This is required by newer device-trees where we model the LVDS encoder bridge properly. Changelog: v8: - The new of_graph_get_local_port() helper is replaced with the of_graph_presents(), which simply checks the graph presence in a given DT node. Thank to Laurent Pinchart for the suggestion! - The of_graph_get_local_port() is still there, but now it isn't a public function anymore. In the review to v7 Laurent Pinchart suggested that the function's doc-comments and name could be improved and I implemented these suggestions in v8. - A day ago I discovered that devm_drm_panel_bridge_add() requires panel to have connector type to be properly set, otherwise function rejects panels with the incomplete description. So, I checked what LVDS panels are used on Tegra and fixed the missing connector types in this new patch: drm/panel-simple: Add missing connector type for some panels v7: - Removed the obscure unused structs (which GCC doesn't detect, but CLANG does) in the patch "Wrap directly-connected panel into DRM bridge", which was reported by kernel test robot for v6. v6: - Added r-b and acks from Rob Herring and Sam Ravnborg. - Rebased on a recent linux-next, patches now apply without fuzz. v5: - Added new patches that make drm_of_find_panel_or_bridge() more usable if graph isn't defined in a device-tree: of_graph: add of_graph_get_local_port() drm/of: Make drm_of_find_panel_or_bridge() to check graph's presence - Updated "Support DRM bridges" patch to use drm_of_find_panel_or_bridge() directly and added WARN_ON(output->panel || output->bridge) sanity-check. - Added new "Wrap directly-connected panel into DRM bridge" patch, as was suggested by Laurent Pinchart. v4: - Following review comments that were made by Laurent Pinchart to the v3, we now create and use the "bridge connector". v3: - Following recommendation from Sam Ravnborg, the new bridge attachment model is now being used, i.e. we ask bridge to *not* create a connector using the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag. - The bridge is now created only for the RGB (LVDS) output, and only when necessary. For now we don't need bridges for HDMI or DSI outputs. - I noticed that we're leaking OF node in the panel's error code path, this is fixed now by the new patch "Don't leak OF node on error". v2: - Added the new "rgb: Don't register connector if bridge is used" patch, which hides the unused connector provided by the Tegra DRM driver when bridge is used, since bridge provides its own connector to us. Dmitry Osipenko (7): of_graph: add of_graph_presents() drm/of: Make drm_of_find_panel_or_bridge() to check graph's presence drm/tegra: output: Don't leak OF node on error drm/tegra: output: Support DRM bridges drm/tegra: output: rgb: Support LVDS encoder bridge drm/tegra: output: rgb: Wrap directly-connected panel into DRM bridge drm/panel-simple: Add missing connector type for some panels drivers/gpu/drm/drm_of.c | 9 +++ drivers/gpu/drm/panel/panel-simple.c | 7 ++ drivers/gpu/drm/tegra/drm.h | 2 + drivers/gpu/drm/tegra/output.c | 21 ++++-- drivers/gpu/drm/tegra/rgb.c | 102 ++++++++++++++------------- drivers/of/property.c | 52 +++++++++++--- include/linux/of_graph.h | 6 ++ 7 files changed, 137 insertions(+), 62 deletions(-) -- 2.26.0

[PATCH] dt-bindings: backlight: Convert common backlight bindings to DT schema
by Rob Herring 30 Jun '20

30 Jun '20

Convert the common GPIO, LED, and PWM backlight bindings to DT schema format. Given there's only 2 common properties and the descriptions are slightly different, I opted to not create a common backlight schema.

[PATCH v5 0/8] Enable ili9341 and l3gd20 on stm32f429-disco
by dillon.minfei＠gmail.com 30 Jun '20

30 Jun '20

From: dillon min <dillon.minfei(a)gmail.com> V5's update based on Mark Brown's suggestion, use 'SPI_MASTER_MUST_RX' for SPI_SIMPLEX_RX mode on stm32 spi controller. V5: 1 instead of add send dummy data out under SIMPLEX_RX mode, add flags 'SPI_CONTROLLER_MUST_TX' for stm32 spi driver 2 bypass 'SPI_CONTROLLER_MUST_TX' and 'SPI_CONTROLLER_MUST_RX' under 'SPI_3WIRE' mode V4: According to alexandre torgue's suggestion, combine ili9341 and l3gd20's modification on stm32f429-disco board to one patchset. Changes: ili9341: 1 update ili9341 panel driver according to Linus's suggestion 2 drop V1's No.5 patch, sumbit new changes for clk-stm32f4 3 merge l3gd20's change to this patchset V3: 1 merge original tiny/ili9341.c driver to panel/panel-ilitek-ili9341.c to support serial spi & parallel rgb interface in one driver. 2 update ilitek,ili9341.yaml dts binding documentation. 3 update stm32f429-disco dts binding V2: 1 verify ilitek,ili9341.yaml with make O=../linux-stm32 dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/panel/ ilitek,ili9341.yaml V1: 1 add ili9341 drm panel driver 2 add ltdc, spi5 controller for stm32f429-disco 3 add ltdc, spi5 pin map for stm32f429-disco 4 add docs about ili9341 5 fix ltdc driver loading hang in clk set rate bug L3gd20: V3: 1 merge stm32f429-disco dtbs binding with ili9341 part V2: 1 insert blank line at stm32f420-disco.dts line 143 2 add more description for l3gd20 in commit message V1: 1 enable spi5 controller on stm32f429-disco (dts) 2 add spi5 pinmap for stm32f429-disco (dts) 3 add SPI_SIMPLEX_RX, SPI_3WIRE_RX support for stm32f4 dillon min (8): ARM: dts: stm32: Add dma config for spi5 ARM: dts: stm32: Add pin map for ltdc & spi5 on stm32f429-disco board ARM: dts: stm32: enable ltdc binding with ili9341, gyro l3gd20 on stm32429-disco board dt-bindings: display: panel: Add ilitek ili9341 panel bindings clk: stm32: Fix stm32f429's ltdc driver hang in set clock rate, fix duplicated ltdc clock register to 'clk_core' case ltdc's clock turn off by clk_disable_unused() drm/panel: Add ilitek ili9341 panel driver spi: stm32: Add 'SPI_SIMPLEX_RX', 'SPI_3WIRE_RX' support for stm32f4 spi: flags 'SPI_CONTROLLER_MUST_RX' and 'SPI_CONTROLLER_MUST_TX' can't be coexit with 'SPI_3WIRE' mode .../bindings/display/panel/ilitek,ili9341.yaml | 69 ++ arch/arm/boot/dts/stm32f4-pinctrl.dtsi | 67 + arch/arm/boot/dts/stm32f429-disco.dts | 48 + arch/arm/boot/dts/stm32f429.dtsi | 3 + drivers/clk/clk-stm32f4.c | 7 +- drivers/gpu/drm/panel/Kconfig | 12 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-ilitek-ili9341.c | 1301 ++++++++++++++++++++ drivers/spi/spi-stm32.c | 19 +- drivers/spi/spi.c | 3 +- 10 files changed, 1521 insertions(+), 9 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/panel/ilitek,ili9341.yaml create mode 100644 drivers/gpu/drm/panel/panel-ilitek-ili9341.c -- 2.7.4

[PATCH] drm/i915/display: fix missing null check on allocated dsb object
by Colin King 30 Jun '20

30 Jun '20

From: Colin Ian King <colin.king(a)canonical.com> Currently there is no null check for a failed memory allocation on the dsb object and without this a null pointer dereference error can occur. Fix this by adding a null check. Note: added a drm_err message in keeping with the error message style in the function.
