* [PATCH v4 11/16] dt-bindings: pinctrl: samsung: Add compatible for Tesla FSD SoC

Add compatible for Tesla Full Self-Driving SoC. The
pinctrl hardware IP is similar to what found on most of the
Exynos series of SoC, so this new compatible is added in
Samsung pinctrl binding.

* [PATCH v4 02/16] dt-bindings: clock: Add bindings definitions for FSD CMU blocks

In-Reply-To: <20220123190729.1852-1-alim.akhtar@samsung.com>
Clock controller driver of FSD platform is designed to have separate
instances for each particular CMU. So clock IDs in this bindings header
also start from 1 for each CMU block.

Adds basic support for the Tesla Full Self-Driving (FSD)
SoC. This SoC contains three clusters of four Cortex-A72 CPUs,
as well as several IPs.
Patches 1 to 9 provide support for the clock controller
(which is designed similarly to Exynos SoCs).
The remaining changes provide pinmux support, initial device tree support.
- Changes since v3
* Addressed Stefen's review comments on patch 14/16
* Fixed kernel test robot warning on patch 04/16
* rebsaed this series on Krzysztof's pinmux new binding schema work [1]
- Changes since v2
* Addressed Krzysztof's and Stephen's review comments
* Added Reviewed-by and Acked-by tags
* Rebased on next-20220120
- Changes since v1
* fixed make dt_binding_check error as pointed by Rob
* Addressed Krzysztof's and Rob's review comments
* Added Reviewed-by and Acked-by tags
* Dropped SPI, MCT and ADC from this series (to be posted in small sets)
NOTE: These patches are based on Krzysztof's pinmux for-next branch

* [PATCH 4/5] drivers: bus: add driver for initializing the SSC bus on (some) qcom SoCs

In-Reply-To: <20220123183547.15830-1-michael.srba@seznam.cz>
From: Michael Srba <Michael.Srba@seznam.cz>
This patch adds bindings for the AHB bus which exposes the SCC block in
the global address space. This bus (and the SSC block itself) is present
on certain qcom SoCs.
In typical configuration, this bus (as some of the clocks and registers
that we need to manipulate) is not accessible to Linux, and the resources
on this bus are indirectly accessed by communicating with a hexagon CPU
core residing in the SSC block. In this configuration, the hypervisor is
the one performing the bus initialization for the purposes of bringing
the haxagon CPU core out of reset.
However, it is possible to change the configuration, in which case this
driver will initialize the bus.
In combination with drivers for resources on the SSC bus, this driver can
aid in debugging, and for example with a TLMM driver can be used to
directly access SSC-dedicated GPIO pins, removing the need to commit
to a particular usecase during hw design.
Finally, until open firmware for the hexagon core is available, this
approach allows for using sensors hooked up to SSC-dedicated GPIO pins
on mainline Linux simply by utilizing the existing in-tree drivers for
these sensors.

This patch adds four clocks which need to be manipulated in order to

Care should be taken not to write to these registers unless the device is
known to be configured such that writing to these registers from Linux
is permitted.

* [PATCH v2 3/5] dt-bindings: bus: add device tree bindings for qcom,ssc-block-bus

From: Michael Srba <Michael.Srba@seznam.cz>
This patch adds bindings for the AHB bus which exposes the SCC block in
the global address space. This bus (and the SSC block itself) is present
on certain qcom SoCs.
In typical configuration, this bus (as some of the clocks and registers
that we need to manipulate) is not accessible to the OS, and the
resources on this bus are indirectly accessed by communicating with a
hexagon CPU core residing in the SSC block. In this configuration, the
hypervisor is the one performing the bus initialization for the purposes
of bringing the haxagon CPU core out of reset.
However, it is possible to change the configuration, in which case this
binding serves to allow the OS to initialize the bus.

+
+description: |
+ This binding describes the dependencies (clocks, resets, power domains) which
+ need to be turned on in a sequence before communication over the AHB bus
+ becomes possible.
+
+ Additionally, the reg property is used to pass to the driver the location of
+ two sadly undocumented registers which need to be poked as part of the sequence.
+
+ Currently, this binding is known to apply to msm8998. If the binding applies
+ in it's current form, the compatible should contain "qcom,ssc-block-bus-v1".
+ If the binding needs tweaking in order to apply to another SoC, this binding
+ shall be extended.

I'd drop this (and the colorspace field in ti_csi2rx_fmt). This driver
doesn't care about colorspaces, it should accept any value set by
userspace, which should match the colorspace produced by the source
subdev.
ti_csi2rx_v4l2_init() will have to set a default colorspace explicitly.

You should adjust the field, not return an error, so this can just
become

I would inline the ti_csi2rx_video_register() function here, it's not
large, and it's only called in a single place.

Is there any hardware frame counter that could be used, to detect
dropped frames ? Or maybe a SOF hardware interrupt somewhere (either in

If this buffer fails to be queued, do you expect that the next buffer in
the list would succeed ? It seems to be a fatal error to me.

> + break;
Shouldn't all pending buffers be queued to the DMA engine ? It seems
that you're queuing one buffer at a time, which would cause an underrun
if the system is too slow to queue the next buffer during vertical
blanking. It defeats the point of having multiple buffers in the V4L2
queue. You should instead queue the buffers to the DMA engine as soon as
they're received by the driver.

Shouldn't you start DMA before starting the source subdev ? You may miss
the first frame otherwise.

... to here could be moved to a separate function that takes a VB2 buf
state parameter, to be also used in the error path of
ti_csi2rx_start_streaming().

Usage of USERPTR and READ is not recommended, I'd drop them from the
driver.

That's interesting, why do you use the dmaengine device and not csi->dev
?

struct dma_slave_config cfg = { };
and you can drop the memset below. Or possibly even better,
struct dma_slave_config cfg = {
.src_addr_with = DMA_SLAVE_BUSWIDTH_16_BYTES,
};

You can also drop V4L2_CAP_READWRITE if you drop VB2_READ above.

Don't use devm_kzalloc() here (see the explanation in the remove
function).

That's not right, capture should instead be stopped.
The right way to handle this is to call all the unregister functions
here, but not the cleanup functions, and to implement a real
vdev->release handler that will perform all the cleanup and kfree() the
ti_csi2rx_dev.

I'd drop the version, it will never change, so it's quite pointless. If
userspace needs to know if the driver implements a particular feature or
includes a bug fix, it can use the kernel version.

I don't see any warnings about it:

Yes, it was under the phy_external node:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/staging/mt7621-dts/mt7621.dtsi#n350
I had put it under gmac1 node instead since we didn't enable the
phy_external node.
