media: i2c: ov5695: Fix power on and off sequences
From the measured hardware signal, OV5695 reset pin goes high for a
short period of time during boot-up. From the sensor specification, the
reset pin is active low and the DT binding defines the pin as active
low, which means that the values set by the driver are inverted and thus
the value requested in probe ends up high.
Fix it by changing probe to request the reset GPIO initialized to high,
which makes the initial state of the physical signal low.
In addition, DOVDD rising must occur before DVDD rising from spec., but
regulator_bulk_enable() API enables all the regulators asynchronously.
Use an explicit loops of regulator_enable() instead.
For power off sequence, it is required that DVDD falls first. Given the
bulk API does not give any guarantee about the order of regulators,
change the driver to use regulator_disable() instead.
The sensor also requires a delay between reset high and first I2C
transaction, which was assumed to be 8192 XVCLK cycles, but 1ms is
recommended by the vendor. Fix this as well.

media: ti-vpe: cal: fix a kernel oops when unloading module
After the switch to use v4l2_async_notifier_add_subdev() and
v4l2_async_notifier_cleanup(), unloading the ti_cal module would cause a
kernel oops.
This was root cause to the fact that v4l2_async_notifier_cleanup() tries
to kfree the asd pointer passed into v4l2_async_notifier_add_subdev().
In our case the asd reference was from a statically allocated struct.
So in effect v4l2_async_notifier_cleanup() was trying to free a pointer
that was not kalloc.
So here we switch to using a kzalloc struct instead of a static one.
To achieve this we re-order some of the calls to prevent asd allocation
from leaking.

Since the draining and stop phase of the HW decoder mem2mem bahaviour is
now clearly defined, we can move handling of the following states to the
common v4l2-mem2mem core code:
- draining
- stopped
- next-buf-is-last
By introducing the following v4l2-mem2mem APIs:
- v4l2_m2m_encoder_cmd/v4l2_m2m_ioctl_encoder_cmd to handle start/stop command
- v4l2_m2m_decoder_cmd/v4l2_m2m_ioctl_decoder_cmd to handle start/stop command
- v4l2_m2m_update_start_streaming_state to update state on start of streaming
of the de/encoder queue
- v4l2_m2m_update_stop_streaming_state to update state on stop of streaming
of the de/encoder queue
- v4l2_m2m_last_buffer_done to make the current dest buffer as the last one
And inline helpers:
- v4l2_m2m_mark_stopped to mark the de/encoding process as stopped
- v4l2_m2m_clear_state to clear the de/encoding state
- v4l2_m2m_dst_buf_is_last to detect the current dequeued dst_buf is the last
- v4l2_m2m_has_stopped to detect the de/encoding stopped state
- v4l2_m2m_is_last_draining_src_buf to detect the current source buffer should
be the last processing before stopping the de/encoding process
The special next-buf-is-last when min_buffers != 1 case is also handled
in v4l2_m2m_qbuf() by reusing the other introduced APIs.
This state management has been stolen from the vicodec implementation,
and is no-op for drivers not calling the v4l2_m2m_encoder_cmd or
v4l2_m2m_decoder_cmd and v4l2_m2m_update_start/stop_streaming_state.
