vi_sensor gated through csus - TEGRA30_CLK_CLK_MAX moved to clk-tegra30 - adjusted commit titles and messages - clk_register_clkdev dropped from pad clock registration - removed tegra30-vi/vip and used tegra20 fallback - added separate csi schema for tegra20-csi and tegra30-csi - fixet number of VI channels - adjusted tegra_vi_out naming - fixed yuv_input_format to main_input_format - MIPI calibration refsctored for Tegra114+ and added support for pre-Tegra114 to use CSI as a MIPI calibration device - switched ENOMEM to EBUSY - added check into tegra_channel_get_remote_csi_subdev - moved avdd-dsi-csi-supply into CSI - next_fs_sp_idx > next_fs_sp_value - removed host1x_syncpt_incr from framecounted syncpoint - csi subdev request moved before frame cycle Changes in v3: - tegra20 and tegra30 csi schema merged - removed unneeded properties and requirements from schema - improved vendor specific properties description - added tegra20 csus parent mux - improved commit descriptions - redesigned MIPI-calibration to expose less SoC related data into header - commit "staging: media: tegra-video: csi: add support for SoCs with integrated MIPI calibration" dropped as unneeded - improved tegra_channel_get_remote_device_subdev logic - avdd-dsi-csi-supply moved from vi to csi for p2597 and p3450-0000 - software syncpoint counters switched to direct reading - adjusted planar formats offset calculation Changes in v4: - removed ifdefs from tegra_mipi_driver - document Tegra132 MIPI calibration device - switched to use BIT macro in tegra114-mipi - pinctrl changes moved to a separate patch - ERESTARTSYS workaround preserved for now - tegra_mipi_add_provider replaced with devm_tegra_mipi_add_provider - reworked bytesperline and sizeimage calculaion --- Svyatoslav Ryhel (24): pinctrl: tegra20: register csus_mux clock clk: tegra: set CSUS as vi_sensor's gate for Tegra20, Tegra30 and Tegra114 dt-bindings: clock: tegra30: Add IDs for CSI pad clocks clk: tegra30: add CSI pad clock gates dt-bindings: display: tegra: document Tegra30 VI and VIP staging: media: tegra-video: expand VI and VIP support to Tegra30 staging: media: tegra-video: vi: adjust get_selection op check staging: media: tegra-video: vi: add flip controls only if no source controls are provided staging: media: tegra-video: csi: move CSI helpers to header gpu: host1x: convert MIPI to use operation function pointers dt-bindings: display: tegra: document Tegra132 MIPI calibration device staging: media: tegra-video: vi: improve logic of source requesting staging: media: tegra-video: csi: move avdd-dsi-csi-supply from VI to CSI arm64: tegra: move avdd-dsi-csi-supply into CSI node staging: media: tegra-video: tegra20: set correct maximum width and height staging: media: tegra-video: tegra20: add support for second output of VI staging: media: tegra-video: tegra20: adjust format align calculations staging: media: tegra-video: tegra20: set VI HW revision staging: media: tegra-video: tegra20: increase maximum VI clock frequency staging: media: tegra-video: tegra20: expand format support with RAW8/10 and YUV422/YUV420p 1X16 staging: media: tegra-video: tegra20: adjust luma buffer stride dt-bindings: display: tegra: document Tegra20 and Tegra30 CSI ARM: tegra: add CSI nodes for Tegra20 and Tegra30 staging: media: tegra-video: add CSI support for Tegra20 and Tegra30 .../display/tegra/nvidia,tegra114-mipi.yaml | 1 + .../display/tegra/nvidia,tegra20-csi.yaml | 135 +++ .../display/tegra/nvidia,tegra20-vi.yaml | 19 +- .../display/tegra/nvidia,tegra20-vip.yaml | 9 +- arch/arm/boot/dts/nvidia/tegra20.dtsi | 19 +- arch/arm/boot/dts/nvidia/tegra30.dtsi | 24 +- .../arm64/boot/dts/nvidia/tegra210-p2597.dtsi | 4 +- .../boot/dts/nvidia/tegra210-p3450-0000.dts | 4 +- drivers/clk/tegra/clk-tegra114.c | 7 +- drivers/clk/tegra/clk-tegra20.c | 20 +- drivers/clk/tegra/clk-tegra30.c | 21 +- drivers/gpu/drm/tegra/dsi.c | 1 + drivers/gpu/host1x/Makefile | 1 + drivers/gpu/host1x/mipi.c | 525 ++---------- drivers/gpu/host1x/tegra114-mipi.c | 483 +++++++++++ drivers/pinctrl/tegra/pinctrl-tegra20.c | 11 +- drivers/staging/media/tegra-video/Makefile | 1 + drivers/staging/media/tegra-video/csi.c | 70 +- drivers/staging/media/tegra-video/csi.h | 16 + drivers/staging/media/tegra-video/tegra20.c | 808 +++++++++++++++--- drivers/staging/media/tegra-video/vi.c | 56 +- drivers/staging/media/tegra-video/vi.h | 6 +- drivers/staging/media/tegra-video/video.c | 8 +- drivers/staging/media/tegra-video/vip.c | 4 +- include/dt-bindings/clock/tegra30-car.h | 3 +- include/linux/host1x.h | 10 -
