Subject: [PATCH v3 0/2] drm/komeda: Add SMMU support on Komeda driver

Hi,

This serie aims at adding the support for SMMU on Komeda driver.
Also updates the device-tree doc about how to enable SMMU by devicetree.

This patch series depends on:
- https://patchwork.freedesktop.org/series/58710/
- https://patchwork.freedesktop.org/series/59000/
- https://patchwork.freedesktop.org/series/59002/
- https://patchwork.freedesktop.org/series/61650/

Changes since v1:
- Rebase to the patch in which convert dp_wait_cond() was changed to
return -ETIMEDOUT and update d71_disconnect_iommu() to be consistent.
- If connected IOMMU failed, set mdev->iommu as NULL.

Changes since v2:
- Correct the code flow by not returning -ETIMEDOUT if dp_wait_cond()
returns zero in d71_connect_iommu().

Thanks,
Lowry
