platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.
In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq().

Stop the CODA960 JPEG encoder from overflowing capture buffers.

Commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
added pm_runtime_resume_and_get() in order to automatically handle
dev->power.usage_count decrement on errors.
Use the new API, in order to cleanup the error check logic.
While here, as noted by Phillip, the labels at the coda_open()
function are currently named after what operation failed,
instead of what they do in response. So, change the name of
the error label that it is called when clk_enable fails,
in order to be consistent.

during streamon() this ioctl gets called for all (encoder and decoder)
devices and on encoder devices this causes a null pointer exception.

To avoid potentially overflowing the kernel logs in the case
of corrupted streams, this commit replaces an error message with
a per-stream counter to be read through a driver-specific
control.
Applications can read the per-stream accumulated
error macroblocks count.

It's possible that the VPU was initialized using just one buffer,
containing only codec headers.
In this case, right after the initialization and after updating
the FIFO read pointer, we need to iterate through all the coda_buffer_meta
and release any metas that have been already used by the VPU.
This issue is affecting indirectly the bitstream buffer fill
threshold, which depends on the meta end position of the first
queued meta, which is passed to coda_bitstream_can_fetch_past().
Without this fix, it's possible that for certain videos, the
bitstream buffer level is not filled properly, resulting in a PIC_RUN
timeout.

meaning that the table lenghts and values don't match the standard table

Similar to commit 9ee50a9489f1 ("media: coda: lock capture queue wakeup
against encoder stop command"), make sure that a JPEG decoder stop
command running concurrently with a decoder finish_run always either
flags the last returned buffer or wakes up the capture queue to signal
the end of stream condition afterwards.
This was not necessary for BIT processor contexts because of the need to
release the bitstream buffer with the stream end condition. In contrast,
the JPEG decoder can be finished with decoding the image between the
time the application queues the last output buffer and the time it
issues the decoder stop command.

capture), currently the value vb2_buf.index + CODA_MAX_FRAMEBUFFERS (19)
is written into the DEC_PIC_ROT_INDEX register. At least with firmware

All accesses are either done by hardware DMA masters or userspace
mapping the buffers. This means we don't need a kernel virtual

space by requesting to not have a kernel mapping set up for them.
