      media: camss: Split power domain management · 46cc0317
      Vladimir Zapolskiy authored 
      There are three cases of power domain management on supported platforms:
1) CAMSS on MSM8916, where a single VFE power domain is operated outside
   of the camss device driver,
2) CAMSS on MSM8996 and SDM630/SDM660, where two VFE power domains are
   managed separately by the camss device driver, the power domains are
   linked and unlinked on demand by their functions vfe_pm_domain_on()
   and vfe_pm_domain_off() respectively,
3) CAMSS on SDM845 and SM8250 platforms, and there are two VFE power
   domains and their parent power domain TITAN_TOP, the latter one
   shall be turned on prior to turning on any of VFE power domains.

Due to a previously missing link between TITAN_TOP and VFEx power domains
in the latter case, which is now fixed by [1], it was decided always to
turn on all found VFE power domains and TITAN_TOP power domain, even if
just one particular VFE is needed to be enabled or none of VFE power
domains are required, for instance the latter case is when vfe_lite is in
use. This misusage becomes more incovenient and clumsy, if next generations
are to be supported, for instance CAMSS on SM8450 has three VFE power
domains.

The change splits the power management support for platforms with TITAN_TOP
parent power domain, and, since 'power-domain-names' property is not
present in camss device tree nodes, the assumption is that the first
N power domains from the 'power-domains' list correspond to VFE power
domains, and, if the number of power domains is greater than number of
non-lite VFEs, then the last power domain from the list is the TITAN_TOP
power domain.

      media: camss: Collect information about a number of lite VFEs · be11096d
      Vladimir Zapolskiy authored 
      VFE lite IPs are found on CAMSS with TITAN_TOP power domains, and in
some aspects these types of VFEs are different, in particular there
is no need to enable VFE power domains to operate over VFE lite IPs.

      media: camss: Do not attach an already attached power domain on MSM8916 platform · 3d658980
      Vladimir Zapolskiy authored 
      The change to dynamically allocated power domains neglected a case of
CAMSS on MSM8916 platform, where a single VFE power domain is neither
attached, linked or managed in runtime in any way explicitly.

This is a special case and it shall be kept as is, because the power
domain management is done outside of the driver, and it's very different
in comparison to all other platforms supported by CAMSS.

      media: camss: Clean up received buffers on failed start of streaming · c8f35823
      Vladimir Zapolskiy authored 
      It is required to return the received buffers, if streaming can not be
started. For instance media_pipeline_start() may fail with EPIPE, if
a link validation between entities is not passed, and in such a case
a user gets a kernel warning:

  WARNING: CPU: 1 PID: 520 at drivers/media/common/videobuf2/videobuf2-core.c:1592 vb2_start_streaming+0xec/0x160
  <snip>
  Call trace:
   vb2_start_streaming+0xec/0x160

   video_usercopy+0x37c/0x7b0
   video_ioctl2+0x24/0x40
   v4l2_ioctl+0x4c/0x70

The fix is to correct the error path in video_start_streaming() of camss.
