These 4 patches fix two issues that existed on Tegra regarding DMA: 1) The bit indicating whether to use an IOMMU or not was hardcoded ; make this a platform property and use it in instmem 2) The DMA mask was not set for platform devices. Fix this by converting more pci_dma* to the DMA API, and use that more generic code to set the DMA mask properly for all platforms. Tested on both x86

This patch series is the leftovers of a patch series sent in September 2023 [1] in an attempt to get some of the patches landed finally. This patch series originally came about after a _long_ discussion between me and Maxime Ripard in response to a different patch I sent out [2]. As part of that discussion, we realized that it would be good if DRM drivers consistently called

This patch series came about after a _long_ discussion between me and Maxime Ripard in response to a different patch I sent out [1]. As part of that discussion, we realized that it would be good if DRM drivers consistently called drm_atomic_helper_shutdown() properly at shutdown and driver remove time as it's documented that they should do. The eventual goal of this would be to enable removing

GP10B is the chip used in Tegra X2 SoCs. This patchset adds support for its base engines after reworking secboot a bit to accomodate its calling convention better. This patchset has been tested rendering simple off-screen buffers using Mesa and yielded the expected result. Alexandre Courbot (15): secboot: allow to boot multiple falcons secboot: pass instance to LS firmware loaders secboot:
