2018-06-28media: venus: keep resolution when adjusting formatAlexandre Courbot2-4/+0
When checking a format for validity, the resolution is reset to 1280x720 whenever the pixel format is not supported. This behavior can mislead user-space into believing that this is the only resolution supported, and looks strange considering that if we try/set the same format with just the pixel format changed to a valid one, the call will this time succeed without altering the resolution. Resolution is managed independently of the pixel format, so remove this reset.

2018-06-28media: rcar-vin: sync which hardware buffer to start capture fromNiklas Söderlund2-1/+17
When starting the VIN capture procedure we are not guaranteed that the first buffer written to is VnMB1 to which we assigned the first buffer queued. This is problematic for two reasons. Buffers might not be dequeued in the same order they where queued for capture. Future features planed for the VIN driver is support for outputting frames in SEQ_TB/BT format and to do that it's important that capture starts from the first buffer slot, VnMB1. We are guaranteed that capturing always happens in sequence (VnMB1 -> VnMB2 -> VnMB3 -> VnMB1). So drop up to two frames when starting capturing so that the driver always returns buffers in the same order they are queued and prepare for SEQ_TB/BT output.

2018-06-26bpf: fix attach type BPF_LIRC_MODE2 dependency wrt CONFIG_CGROUP_BPFSean Young1-12/+2
If the kernel is compiled with CONFIG_CGROUP_BPF not enabled, it is not possible to attach, detach or query IR BPF programs to /dev/lircN devices, making them impossible to use. For embedded devices, it should be possible to use IR decoding without cgroups or CONFIG_CGROUP_BPF enabled. This change requires some refactoring, since bpf_prog_{attach,detach,query} functions are now always compiled, but their code paths for cgroups need moving out. Rather than a #ifdef CONFIG_CGROUP_BPF in kernel/bpf/syscall.c, moving them to kernel/bpf/cgroup.c and kernel/bpf/sockmap.c does not require #ifdefs since that is already conditionally compiled.

2018-06-18media: pxa_camera: remove the dmaengine compat needRobert Jarzmik1-19/+3
