[Why] If the payload_state is DP_PAYLOAD_DELETE_LOCAL in series, current code doesn't delete the payload at current index and just move the index to next one after shuffling payloads. [How] Drop the i++ increasing part in for loop head and decide whether to increase the index or not according to payload_state of current payload. Changes since v1: * Refine the code to have it easy reading * Amend the commit message to meet the way code is modified now. Signed-off-by:

cec4fa75 ("drm/omap: use refcount API to track the number of users of dma_addr") changed omap_gem.c to use refcounting API to track dma_addr uses. However, the driver only tracks the refcounts for non-contiguous buffers, and the patch didn't fully take this in account. After the patch, the driver always decreased refcount in omap_gem_unpin, instead of decreasing the refcount only for non-contiguous buffers. This leads to refcounting mismatch. As for the contiguous cases the refcount is never increased, fix this issue by returning from omap_gem_unpin if the buffer being unpinned is contiguous. Signed-off-by:

The SOR supports multiple display modes, but only when driving an HDMI monitor does it make sense to control the +5V power supply. eDP and DP don't need this, so make it optional. This fixes a crash observed during system suspend/resume. Reviewed-by:

Export the module device table to ensure the VIC compatible strings are listed in the module's aliases table. This in turn causes the driver to be automatically loaded on boot if VIC is the only enabled subdevice of the logical host1x DRM device. Reviewed-by:

Upon system suspend, make sure the +5V HDMI regulator is disabled. This avoids potentially leaking current to the HDMI connector. This also makes sure that upon resume the regulator is enabled again, which in some cases is necessary to properly restore the state of the supply on resume. Reviewed-by:

All the display related blocks on Tegra require contiguous memory. Using the DMA API, there is no knowing at import time which device will end up using the buffer, so it's not known whether or not an IOMMU will be used to map the buffer. Move the check for non-contiguous buffers/mappings to the tegra_dc_pin() function which is now the earliest point where it is known if a DMA BUF can be used by the given device or not. v2: add check for contiguous buffer/mapping in tegra_dc_pin() Reviewed-by:

Thierry Reding authored
Buffers that are imported from a DMA-BUF don't have pages allocated with them. At the same time an SG table for them can't be derived using the DMA API helpers because the necessary information doesn't exist. However there's already an SG table that was created during import, so this can simply be duplicated. Signed-off-by: -
