4ae4b2d2b2 camera: oot: use reg number as channel id 
When parsing sensor DT, use vi input endpoint reg
number as chan id. And allocate as many tegra_mc_vi
objects as vi input endpoints.

Remove port index assignment when creating graph.
This can cause issue when csi port index is more
than MAX_NVCSI_STREAM_IDS(6).

06b833d570 block: virt-storage: tegra: Fix build for Linux v5.14 
For Linux v5.14, the function device_add_disk() has a void return type
and compilation now fails with ...

 nvidia-oot/drivers/block/tegra_virt_storage/tegra_hv_vblk.c:1162:8:
 error: invalid use of void expression
  1162 |  (void)!device_add_disk(vblkdev->device, vblkdev->gd, NULL);
       |        ^

Fix the build for kernels prior to v5.15 by not attempting to  access
the return value. Finally, for kernels v5.15 and newer, do not ignore
the return value and report an error if device_add_disk() fails.

78db0d7c41 tsec: Conditionally turn off clock in suspend 
Problem:
=======
In current implementation of tsec_poweroff, tsec clock is getting
turned off unconditionally.

During suspend-resume operation, there is an issue in MB1 as
explained in bug 3796711 (comment 16). Due to this, when
tsec_poweroff function is called for second suspend operation,
tsec clock is turned off even when the power state variable
"pdata->power_on" is not set to true or 1.

This causes the following warning from clock driver highlighting
that tsec clock is already disabled.
