The function kobject_init_and_add alloc memory like: kobject_init_and_add->kobject_add_varg->kobject_set_name_vargs ->kvasprintf_const->kstrdup_const->kstrdup->kmalloc_track_caller ->kmalloc_slab, in err branch this memory not free. If use kmemleak, this path maybe catched. These changes are to add kobject_put in kobject_init_and_add failed branch, fix potential memleak. Signed-off-by:

[why] DP link layer CTS specs updated to change the test parameters in test 4.2.1.1. Before it requires source to delay 400us on aux no reply. With the specs updates Errata5, it requires source to delay 3.2ms (based on LTTPR aux timeout) This causes our test to fail after updating with the latest test equipment firmware. [how] the change is to allow LTTPR 3.2ms aux timeout delay by default. And set back to 400us if LTTPR feature is not enabled. We will set 3.2ms and always enable LTTPR non transparent mode if LTTPR feature is enabled and LTTPR is present. Signed-off-by:

[Why] DMCUB firmware version is now available from firmware metadata block. We should be passing this into dmub_srv so we can know when to apply firmware version specific functionality like using CW4 only instead of the REGION4. [How] We don't have the helpers for DM to actually extract out firmware metadata block themselves. We could add that and add helpers in DM to grab this, but not every creation sequence has firmware instruction before dmub_srv_create. Easiest way to handle this is to fill this in automatically per DM in the place we do have it - when calculating the region parameters. But only fill it in if DM already hasn't in case we need to override with a specific version. We aren't do anything firmware version specific in dmub_srv_create today that does require fw_version, so while it's a little unituitive to do it when calculating region parameters it works for now.

[Why] All YCbCr420 resolutions 5K and above have tiling and discoloration issues. The issue can be remedied by forcing ODM combine from 5K to 8K. 10K resolution requires ODM 4:1. The mechanism of what the real problem is, that is inherent in ODM combine programming, doesn't seem to be pointed at singular register programming (CLK, MPC, DCSURF, etc.), and needs more in-depth programming sequence review for these new use case scenarios. Until then, workaround to enable ODM combine is proposed. While it is not our policy, HW spreadsheet also recommends turning on ODM for these scenario to lower the voltage.

There would choose dppclk for request voltage when dispclk wouldn't be updated case. If dispclk need to be updated, then it'll choose the bigger one from dppclk and dispclk for request voltage.

[Why] DC global validation can fail when userspace requests to draw large plane without performing the clipping themselves. This is observed in the IGT kms_plane panning tests for 4K displays where they draw an 8K plane without any clipping while expecting only the top 4K to be drawn. [How] DRM already has helpers to take care of the clipping necessary and to mark whether a plane is visible or not, so make use of these helpers in DM before passing the plane to DC. Signed-off-by:

[Why] Side-by-side and Top-and-bottom stereo configurations fail DML mode validation due to Viewport exceeded. This is because we consider the planes as being pipe split in pipe population so we end up doubling the viewport width, eg. from 4k to 8k.
