Prepare for adding device_link.
The iommu consumer should use device_link to connect with the
smi-larb(supplier). then the smi-larb should run before the iommu
consumer. Here we delay the iommu driver until the smi driver is ready,
then all the iommu consumers always are after the smi driver.
When there is no this patch, if some consumer drivers run before
smi-larb, the supplier link_status is DL_DEV_NO_DRIVER(0) in the
device_link_add, then device_links_driver_bound will use WARN_ON
to complain that the link_status of supplier is not right.
device_is_bound may be more elegant here. but it is not allowed to
EXPORT from https://lore.kernel.org/patchwork/patch/1334670/.

When the iommu master device enters of_iommu_xlate, the ops may be

[<c06c0d38>] (of_iommu_xlate) from [<c06c10e8>]
(of_iommu_configure+0x144/0x1e8)
BUT the mtk_iommu_v1.c only supports arm32, the probing flow still is a bit
weird. We always expect create the fwspec internally. otherwise it will
enter here and return fail.
static int mtk_iommu_create_mapping(struct device *dev,
struct of_phandle_args *args)

...
if (!fwspec) {
....
} else if (dev_iommu_fwspec_get(dev)->ops != &mtk_iommu_ops) {
>>>>>>>>>>Enter here. return fail.<<<<<<<<<<<<
return -EINVAL;

}
Thus, Free the existed fwspec if the master device already has fwspec.

The quantization tables used in the Hantro JPEG encoder driver are
implicitly sized by the data they contain, but the loop that scales
the tables based on the compression quality hard codes the size to
64. No code exists to check whether the two actually match.
Commit 85bdcb7eaa ("media: hantro: Write the quantization tables in
proper order") introduced two new tables, with sizes hardcoded to 64,
but still no checking if all the sizes are the same.
Commit 41479adb5e ("media: hantro: Avoid global variable for jpeg
quantization tables") added the macro JPEG_QUANT_SIZE, but only the
newly added fields used this.
This has resulted in code scattered with magic numbers and array sizes
that happen to match up, without any sort of sanity checking to enforce
it.
Drop the hard-coded array sizes, replace the magic loop count with
a proper JPEG_QUANT_SIZE macro, and add BUILD_BUG_ON()s to check
that all the table sizes match up.

The Hantro JPEG encoder driver adds various segments to the JPEG header.
While it would be quite complicated to make these segments selectable

the source frame. These are controlled with the H1_REG_IN_IMG_CTRL_OVRFLB
and H1_REG_IN_IMG_CTRL_OVRFLR in the H1_REG_IN_IMG_CTRL register.
The ChromeOS kernel driver that this was based on incorrectly added the
_D4 suffix H1_REG_IN_IMG_CTRL_OVRFLB. This field crops the bottom of the
input frame, and the number is _not_ divided by 4. [1]
Correct the name to avoid confusion when crop support with the selection

The 'maxim,gpio-poc' property is used when the remote camera
power-over-coax is controlled by one of the MAX9286 gpio lines,
to instruct the driver about which line to use and what the line
polarity is.
Add to the max9286 driver support for parsing the newly introduced
property and use it if available in place of the usual supply, as it is
not possible to establish one as consumer of the max9286 gpio
controller.
If the new property is present, no gpio controller is registered and
'poc-supply' is ignored.
In order to maximize code re-use, break out the max9286 gpio handling
function so that they can be used by the gpio controller through the
gpio-consumer API, or directly by the driver code.
Wrap the power up and power down routines to their own function to
be able to use either the gpio line directly or the supply. This will

Use the dma_set_mask_and_coherent helper to set vdec
DMA bit mask to support 34bits iova space(16GB) that
the mt8192 iommu HW support.
Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G,
regarding which iova range VDEC actually locate, it
depends on the dma-ranges property of vdec dtsi node.

Add work queue to process core hardware information.
First, get lat_buf from message queue, then call core
hardware of each codec(H264/VP9/AV1) to decode, finally
puts lat_buf back to the message.

For add new hardware, not only need to lock lat hardware, also
need to lock core hardware in case of different instance start
to decoder at the same time.

For lat and core architecture, lat thread will send message to core
thread when lat decode done. Core hardware will use the message
from lat to decode, then free message to lat thread when decode done.
