[PATCH v13 00/13] media: staging/imx7: add i.MX7 media driver
Hi, This series introduces the Media driver to work with the i.MX7 SoC. it uses the already existing imx media core drivers but since the i.MX7, contrary to i.MX5/6, do not have an IPU and because of that some changes in the imx media core are made along this series to make it support that case. This patches adds CSI and MIPI-CSI2 drivers for i.MX7, along with several configurations changes for this to work as a capture subsystem. Some bugs are also fixed along the line. And necessary documentation. For a more detailed view of the capture paths, pads links in the i.MX7 please take a look at the documentation in PATCH 10. The system used to test and develop this was the Warp7 board with an OV2680 sensor, which output format is 10-bit bayer. So, only MIPI interface was tested, a scenario with an parallel input would nice to have. Bellow goes an example of the output of the pads and links and the output of v4l2-compliance testing. The v4l-utils version used is: v4l2-compliance SHA: 1a6c8fe9a65c26e78ba34bd4aa2df28ede7d00cb, 32 bits The Media Driver fail some tests but this failures are coming from code out of scope of this series (imx-capture), and some from the sensor OV2680 but that I think not related with the sensor driver but with the testing and core. The csi and mipi-csi entities pass all compliance tests.

instead of custom attribute. This is a small step towards removing any
unnecessary custom attribute.

This doesn't match your email. You should probably add a From: to
give your @analog.com address authorship credit.

Only one 'n' in "chan", please. But we actually pass the address not
the channel here so that was unexpected to me. I think the channel is
always the same as the address? So maybe it doesn't matter.

I don't understand why we have two frequencies when we only ever use
one.

[PATCH v14 00/13] media: staging/imx7: add i.MX7 media driver
Hi, This series introduces the Media driver to work with the i.MX7 SoC. it uses the already existing imx media core drivers but since the i.MX7, contrary to i.MX5/6, do not have an IPU and because of that some changes in the imx media core are made along this series to make it support that case. This patches adds CSI and MIPI-CSI2 drivers for i.MX7, along with several configurations changes for this to work as a capture subsystem. Some bugs are also fixed along the line. And necessary documentation. For a more detailed view of the capture paths, pads links in the i.MX7 please take a look at the documentation in PATCH 10. The system used to test and develop this was the Warp7 board with an OV2680 sensor, which output format is 10-bit bayer. So, only MIPI interface was tested, a scenario with an parallel input would nice to have. Bellow goes an example of the output of the pads and links and the output of v4l2-compliance testing. The v4l-utils version used is: v4l2-compliance SHA: 1a6c8fe9a65c26e78ba34bd4aa2df28ede7d00cb, 32 bits The Media Driver fail some tests but this failures are coming from code out of scope of this series (imx-capture), and some from the sensor OV2680 but that I think not related with the sensor driver but with the testing and core.

[PATCH v14 02/13] media: staging/imx: rearrange group id to take in account IPU
Some imx system do not have IPU, so prepare the imx media drivers to
support this kind of devices. Rename the group ids to include an _IPU_
prefix, add a new group id to support systems with only a CSI without
IPU, and also rename the create internal links to make it clear that
only systems with IPU have internal subdevices.

It has two sink pads to select from either camera +sensor with a parallel interface or from MIPI CSI-2 virtual channel 0. It has +a single source pad that routes to the CSI. + +csi +--- + +The CSI enables the chip to connect directly to external CMOS image sensor.

[PATCH v14.1] media: staging/imx: refactor imx media device probe
Refactor and move media device initialization code to a new common
module, so it can be used by other devices, this will allow for example
a near to introduce imx7 CSI driver, to use this media device.

[PATCH net-next v4 00/12] net: Introduce ndo_get_port_parent_id()
Hi all, Based on discussion with Ido and feedback from Jakub there are clearly two classes of users that implement SWITCHDEV_ATTR_ID_PORT_PARENT_ID: - PF/VF drivers which typically only implement return the port's parent ID, yet have to implement switchdev_port_attr_get() just for that - Ethernet switch drivers: mlxsw, ocelot, DSA, etc. which implement more attributes which we want to be able to eventually veto in the context of the caller, thus making them candidates for using a blocking notifier chain Changes in v4: - remove superfluous net/switchdev.h inclusions in a few files - added Jiri's Acked-by where given - removed err = -EOPNOTSUPP initializations - changed according to Jiri's suggestion in net/ipv4/ipmr.c Changes in v3: - keep ethsw's switchdev_ops assignment - remove inclusion of net/switchdev.h in netdevsim which is no longer necesary Changes in v2: - resolved build failures spotted by kbuild test robot - added helpers functions into the core network device layer: dev_get_port_parent_id() and netdev_port_same_parent_id(); - added support for recursion to lower devices Changes from RFC: - introduce a ndo_get_port_parent_id() and convert all relevant drivers to use it - get rid of SWITCHDEV_ATTR_ID_PORT_PARENT_ID A subsequent set of patches will convert switchdev_port_attr_set() to use a blocking notifier call, and still get rid of switchdev_port_attr_get() altogether.

[PATCH net-next v4 02/12] bnxt: Implement ndo_get_port_parent_id()
BNXT only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a
great candidate to be converted to use the ndo_get_port_parent_id() NDO
instead of implementing switchdev_port_attr_get(). The conversion is
straight forward here since the PF and VF code use the same getter.
Since bnxt makes uses of switchdev_port_same_parent_id() convert it to
use netdev_port_same_parent_id().

[PATCH net-next v4 01/12] net: Introduce ndo_get_port_parent_id()
In preparation for getting rid of switchdev_ops, create a dedicated NDO
operation for getting the port's parent identifier. There are
essentially two classes of drivers that need to implement getting the
port's parent ID which are VF/PF drivers with a built-in switch, and
pure switchdev drivers such as mlxsw, ocelot, dsa etc.
We introduce a helper function: dev_get_port_parent_id() which supports
recursion into the lower devices to obtain the first port's parent ID.
Convert the bridge, core and ipv4 multicast routing code to check for
such ndo_get_port_parent_id() and call the helper function when valid
before falling back to switchdev_port_attr_get(). This will allow us to
convert all relevant drivers in one go instead of having to implement
both switchdev_port_attr_get() and ndo_get_port_parent_id() operations,
then get rid of switchdev_port_attr_get().

[PATCH net-next v4 12/12] net: Get rid of SWITCHDEV_ATTR_ID_PORT_PARENT_ID
Now that we have a dedicated NDO for getting a port's parent ID, get rid
of SWITCHDEV_ATTR_ID_PORT_PARENT_ID and convert all callers to use the
NDO exclusively. This is a preliminary change to getting rid of
switchdev_ops eventually.

Finally this will give us a way to distinguish two ports with the same switch
and port IDs on a system with two disjoint switch trees, thanks!

So here's a script that does most all of them except
the 50 or so that use the SPDX-License-Identifier
in the middle of a comment block.
Using:
$ git grep --name-only 'SPDX-License-Identifier:' -- '*.h' | \
xargs grep -L '/\* SPDX-License-Identifier:.*\*/'| \
while read file ; do perl -i update_spdx.perl $file ; done
produces
$ git diff --shortstat

And
$ git grep -h "SPDX-License" -- '*.h' | \
perl -p -e 's@Identifier:.*\*/*@Identifier: ... */@; s@Identifier:

sort | uniq -c | sort -rn

[PATCH 0/9] staging: wilc1000: fixes & changes for mainline review comments
From: Ajay Singh
This series contains the following changes:
- fix to set 'vif_num' value correctly. The previous Fixes patch
for vif count had not fixed the issue completely, so reverted it
and added a new patch to fix the issue.
- use 'wilc_' prefix for variables and function names.
- avoid use of unnecessary 'linux_' prefix from file names.

Set correct interface count value in '->vif_num'.
'vif_num' was incorrectly set one less than total number of interfaces
because 'i' is used to set its value, which starts from 0.

[PATCH 1/9] staging: wilc1000: revert fix related to vif index
From: Ajay Singh
This patch reverts 0e490657c721 ("staging: wilc1000: Fix problem with
wrong vif index") commit.
The issue was not completely fixed with the above commit.
After 'for' loop completion, '->idx' value is correct but '->vif_num'
still contains incorrect interface count.

Re: [Linaro-mm-sig] [PATCH 2/4] staging: android: ion: Restrict cache maintenance to dma mapped memory
The CPU may only access DMA mapped memory if ownership has been
transferred back to the CPU using dma_sync_{single,sg}_to_cpu, and then
before the device can access it again ownership needs to be transferred
back to the device using dma_sync_{single,sg}_to_device.
> I've run some testing, and this patch does indeed fix the crash in
> dma_sync_sg_for_cpu when it tried to use the 0 dma_address from the sg
> list.
>
> Tested-by: Ørjan Eide
>
> I tested this on an older kernel, v4.14, since the dma-mapping code
> moved, in v4.19, to ignore the dma_address and instead use sg_phys() to
> get a valid address from the page, which is always valid in the ion sg

Can you also test is with CONFIG_DMA_API_DEBUG enabled, as that should
catch all the usual mistakes in DMA API usage, including the one found?
