[PATCH] drm/i2c/sil164: Drop no-op remove function
by Uwe Kleine-König 09 Jun '22

09 Jun '22

A remove callback that just returns 0 is equivalent to no callback at all as can be seen in i2c_device_remove(). So simplify accordingly.

[PATCH] drm/ast: Treat AST2600 like AST2500 in most places
by Thomas Zimmermann 09 Jun '22

09 Jun '22

Include AST2600 in most of the branches for AST2500. Thereby revert most effects of commit f9bd00e0ea9d ("drm/ast: Create chip AST2600"). The AST2600 used to be treated like an AST2500, which at least gave usable display output. After introducing AST2600 in the driver without further updates, lots of functions take the wrong branches. Handling AST2600 in the AST2500 branches reverts back to the original settings. The exception are cases where AST2600 meanwhile got its own branch.

[PATCH v6 0/8] Add a panel API to set orientation properly
by Hsin-Yi Wang 09 Jun '22

09 Jun '22

Panels usually call drm_connector_set_panel_orientation(), which is later than drm/kms driver calling drm_dev_register(). This leads to a WARN()[1]. The orientation property is known earlier. For example, some panels parse the property through device tree during probe. The series add a panel API drm_connector_set_orientation_from_panel() for drm/kms drivers. The drivers can call the API to set panel's orientation before drm_dev_register(). Panel needs to implement .get_orientation callback to return the property.

[PATCH] drm: shmobile: Use backlight helper
by Stephen Kitt 08 Jun '22

08 Jun '22

backlight_properties.fb_blank is deprecated. The states it represents are handled by other properties; but instead of accessing those properties directly, drivers should use the helpers provided by backlight.h. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.

[PATCH v2 0/8] drm/i915: ttm for internal
by Robert Beckett 08 Jun '22

08 Jun '22

This series refactors i915's internal buffer backend to use ttm. It uses ttm's pool allocator to allocate volatile pages in place of the old code which rolled its own via alloc_pages. This is continuing progress to align all backends on using ttm. v2: - commit message improvements to add detail - fix i915_ttm_shrink to purge !is_shmem volatile buffers - limit ttm pool allocator to using dma32 on i965G[M] - fix mman selftest to always use smem buffers - create new internal memory region - make internal backend allocate from internal region - Fixed various issues with tests and i915 ttm usage as a result of supporting regions other than lmem via ttm.

[PATCH v1 00/13] Host1x support on Tegra234
by cyndis＠kapsi.fi 08 Jun '22

08 Jun '22

From: Mikko Perttunen <mperttunen(a)nvidia.com> Hi all, This series adds support for Host1x and VIC on the recently released Tegra234 (Orin) SoC. It's split into the following parts: * Device tree binding updates * Cleanup in host1x driver * Add programming of new registers and old registers that now need to be programmed to a non-reset value * Tegra234 device data and headers * Rewrite of the job opcode sequence, and related patches to support MLOCKs on Tegra186+. The rewrite of the job opcode sequence brings Tegra186, Tegra194 and Tegra234 support to a 'full-featured' status that is necessary to support all host1x features in the future. This should not have any impact on older SoCs. This series should be applied on top of the Host1x context isolation series. Tested on Jetson AGX Xavier and Jetson AGX Orin. Thanks, Mikko Mikko Perttunen (13): dt-bindings: Add bindings for Tegra234 Host1x and VIC dt-bindings: Add headers for Host1x and VIC on Tegra234 arm64: tegra: Add Host1x and VIC on Tegra234 gpu: host1x: Deduplicate hardware headers gpu: host1x: Simplify register mapping and add common aperture gpu: host1x: Program virtualization tables gpu: host1x: Allow reset to be missing gpu: host1x: Program interrupt destinations on Tegra234 gpu: host1x: Tegra234 device data and headers gpu: host1x: Rewrite job opcode sequence gpu: host1x: Add MLOCK release code on Tegra234 gpu: host1x: Use RESTART_W to skip timed out jobs on Tegra186+ drm/tegra: vic: Add Tegra234 support .../display/tegra/nvidia,tegra124-vic.yaml | 1 + .../display/tegra/nvidia,tegra20-host1x.yaml | 108 +++++++++-- arch/arm64/boot/dts/nvidia/tegra234.dtsi | 46 +++++ drivers/gpu/drm/tegra/drm.c | 1 + drivers/gpu/drm/tegra/vic.c | 12 ++ drivers/gpu/host1x/Makefile | 3 +- drivers/gpu/host1x/cdma.c | 19 +- drivers/gpu/host1x/dev.c | 112 +++++++---- drivers/gpu/host1x/dev.h | 11 ++ drivers/gpu/host1x/hw/cdma_hw.c | 34 ++++ drivers/gpu/host1x/hw/channel_hw.c | 144 ++++++++------ drivers/gpu/host1x/hw/host1x01_hardware.h | 114 +---------- drivers/gpu/host1x/hw/host1x02_hardware.h | 113 +---------- drivers/gpu/host1x/hw/host1x04_hardware.h | 113 +---------- drivers/gpu/host1x/hw/host1x05_hardware.h | 113 +---------- drivers/gpu/host1x/hw/host1x06_hardware.h | 128 +------------ drivers/gpu/host1x/hw/host1x07_hardware.h | 128 +------------ drivers/gpu/host1x/hw/host1x08.c | 33 ++++ drivers/gpu/host1x/hw/host1x08.h | 15 ++ drivers/gpu/host1x/hw/host1x08_hardware.h | 21 ++ drivers/gpu/host1x/hw/hw_host1x08_channel.h | 11 ++ drivers/gpu/host1x/hw/hw_host1x08_common.h | 11 ++ .../gpu/host1x/hw/hw_host1x08_hypervisor.h | 9 + drivers/gpu/host1x/hw/hw_host1x08_uclass.h | 181 ++++++++++++++++++ drivers/gpu/host1x/hw/hw_host1x08_vm.h | 36 ++++ drivers/gpu/host1x/hw/intr_hw.c | 11 ++ drivers/gpu/host1x/hw/opcodes.h | 150 +++++++++++++++ include/dt-bindings/clock/tegra234-clock.h | 4 + include/dt-bindings/memory/tegra234-mc.h | 5 + .../dt-bindings/power/tegra234-powergate.h | 1 + include/dt-bindings/reset/tegra234-reset.h | 1 + 31 files changed, 877 insertions(+), 812 deletions(-) create mode 100644 drivers/gpu/host1x/hw/host1x08.c create mode 100644 drivers/gpu/host1x/hw/host1x08.h create mode 100644 drivers/gpu/host1x/hw/host1x08_hardware.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x08_channel.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x08_common.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x08_hypervisor.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x08_uclass.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x08_vm.h create mode 100644 drivers/gpu/host1x/hw/opcodes.h -- 2.36.1
