[PATCH v6 01/14] dt-bindings: clk: imx: Add fsl,scu-clk yaml file

[Viorel Suman (OSS)]

From: Abel Vesa <abel.vesa@nxp.com>

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'clock' child node of the SCU main node.

Added them initially, but later dropped because of some logs like
"pinctrl@xxxxxxx: usdhc1grp:fsl,pins:0: [...] is too long" shown by
"make dt_binding_check dtbs_check DT_SCHEMA_FILES=[...]/fsl,scu-pinctrl.yaml"

Same logs are shown for "fsl,imx8mq-pinctrl.yaml". Will add the items description in the next
version.

The fsl,imx8mq-pinctrl.yaml should be correct and I don't see the reason
why dtschema complains in some of the entries. It's like one define was
not correct... I'll take a look at this later, but anyway keep the same
as fsl,imx8mq-pinctrl.yaml even if it complains.

The issue is that 'fsl,pins' is problematic for the new dtb decoding
because it has a variable definition in terms of matrix bounds as each
i.MX platform has its own length (typ 5 or 6). The tools try to work
around it by figuring out which size fits. That works until there are
multiple answers which seems to be what's happening here.

The easiest solution I think is to just strip the constraints in
occurances of this property. I'll look into that.

The issue is that 'fsl,pins' is problematic for the new dtb decoding
because it has a variable definition in terms of matrix bounds as each
i.MX platform has its own length (typ 5 or 6). The tools try to work
around it by figuring out which size fits. That works until there are
multiple answers which seems to be what's happening here.

The easiest solution I think is to just strip the constraints in
occurances of this property. I'll look into that.

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

[PATCH v6 03/14] dt-bindings: input: Add fsl,scu-key yaml file

[Viorel Suman (OSS)]

From: Abel Vesa <abel.vesa@nxp.com>

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'keys' child node of the SCU main node.

[PATCH v6 08/14] dt-bindings: watchdog: Add fsl,scu-wdt yaml file

[Viorel Suman (OSS)]

From: Abel Vesa <abel.vesa@nxp.com>

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'watchdog' child node of the SCU main node.

This depends on all other previous patches, so it cannot go
independently. Therefore I expect that everything will be going through
one tree thus removal of TXT hunks should happen gradually.

So this explains the unexpected change in the bindings... but actually
it does not explain whether it is correct or not. Just because driver
does not use it, is not a proof that clocks are not there. In different
OS/implementation this DTS might break stuff, so basically it is ABI
break. DTS should describe the hardware fully, so if the clocks are
there, should be in DTS regardless of the driver.


Best regards,
Krzysztof

Hi Krzysztof,

Both XTAL clocks - 24MHz and 32kHz - are still defined in DTSI files, see for instance in
arch/arm64/boot/dts/freescale/imx8qxp.dtsi :
---------------
        xtal32k: clock-xtal32k {
                compatible = "fixed-clock";
                #clock-cells = <0>;
                clock-frequency = <32768>;
                clock-output-names = "xtal_32KHz";
        };

        xtal24m: clock-xtal24m {
                compatible = "fixed-clock";
                #clock-cells = <0>;
                clock-frequency = <24000000>;
                clock-output-names = "xtal_24MHz";
        };
---------------
Both can be seen in /sys/kernel/debug/clk/clk_summary once boot is complete, both can be referenced
in any DTS node, so there is no ABI break.

"DTS should describe the hardware fully" - this is true in case the OS is supposed to controll the
hardware fully. i.MX8 System Controller Unit concept implies resources being allocated and managed
by SCU, there is no direct OS access to some hardware. SCU actually defines the hardware environment
the OS is being able to see and run within. SCU is able to define several such isolated hardware
environments, each having its own OS running. So, in this particular case - i.MX8 SCU concept -
DTS should describe the hardware from the perspective of the hardware environment exposed by SCU to
OS.

Best regards,
Viorel

ABI break is not relevant to the fixed clocks being or not being defined
in the DTS. You have a device which was taking the clock inputs, so the
clocks stayed enabled.

Now, you don't take these inputs, so for example the clocks are getting
disabled as not used.

OK, that sounds good, but the question about these clocks remain - are
they inputs to the SCU or not.

Regardless whether they are actual input or not, you used not
appropriate argument here - that Linux OS implementation does not use
them. The proper argument is - whether the hardware environment has them
connected or not.

ABI break is not relevant to the fixed clocks being or not being defined
in the DTS. You have a device which was taking the clock inputs, so the
clocks stayed enabled.

Now, you don't take these inputs, so for example the clocks are getting
disabled as not used.

OK, that sounds good, but the question about these clocks remain - are
they inputs to the SCU or not.

Regardless whether they are actual input or not, you used not
appropriate argument here - that Linux OS implementation does not use
them. The proper argument is - whether the hardware environment has them
connected or not.

The question context looks a bit shifted. The "clocks" and "clock-names"
attributes are removed from a clock provider device.

The OS clock provider in this case is a client which uses some protocol
to communicate with SCU via a messaging unit. There is no
access to xtal clocks via the existing OS<->SCU communication protocol.

SCU does not need to access them via communication protocol. It's enough
that they are clock inputs, physical clocks being fed to your hardware
which you describe in the DTS.

[PATCH v6 14/14] dt-bindings: arm: freescale: Remove fsl,scu txt file

[Viorel Suman (OSS)]

From: Abel Vesa <abel.vesa@nxp.com>

Now that all the child nodes have been properly documented in the
yaml files, within their proper subystems, we can drop the fsl,scu.txt.

-NXP i.MX System Controller Firmware (SCFW)
---------------------------------------------------------------------
-
-The System Controller Firmware (SCFW) is a low-level system function
-which runs on a dedicated Cortex-M core to provide power, clock, and
-resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
-(QM, QP), and i.MX8QX (QXP, DX).
-
-The AP communicates with the SC using a multi-ported MU module found
-in the LSIO subsystem. The current definition of this MU module provides
-5 remote AP connections to the SC to support up to 5 execution environments
-(TZ, HV, standard Linux, etc.). The SC side of this MU module interfaces
-with the LSIO DSC IP bus. The SC firmware will communicate with this MU
-using the MSI bus.
-
-System Controller Device Node:
-============================================================
-
-The scu node with the following properties shall be under the /firmware/ node.
-
-Required properties:
--------------------
-- compatible:	should be "fsl,imx-scu".
-- mbox-names:	should include "tx0", "tx1", "tx2", "tx3",
-			       "rx0", "rx1", "rx2", "rx3";
-		include "gip3" if want to support general MU interrupt.
-- mboxes:	List of phandle of 4 MU channels for tx, 4 MU channels for
-		rx, and 1 optional MU channel for general interrupt.
-		All MU channels must be in the same MU instance.
-		Cross instances are not allowed. The MU instance can only
-		be one of LSIO MU0~M4 for imx8qxp and imx8qm. Users need
-		to make sure use the one which is not conflict with other
-		execution environments. e.g. ATF.
-		Note:
-		Channel 0 must be "tx0" or "rx0".
-		Channel 1 must be "tx1" or "rx1".
-		Channel 2 must be "tx2" or "rx2".
-		Channel 3 must be "tx3" or "rx3".
-		General interrupt rx channel must be "gip3".
-		e.g.
-		mboxes = <&lsio_mu1 0 0
-			  &lsio_mu1 0 1
-			  &lsio_mu1 0 2
-			  &lsio_mu1 0 3
-			  &lsio_mu1 1 0
-			  &lsio_mu1 1 1
-			  &lsio_mu1 1 2
-			  &lsio_mu1 1 3
-			  &lsio_mu1 3 3>;
-		See Documentation/devicetree/bindings/mailbox/fsl,mu.yaml
-		for detailed mailbox binding.
-
-Note: Each mu which supports general interrupt should have an alias correctly
-numbered in "aliases" node.
-e.g.
-aliases {
-	mu1 = &lsio_mu1;
-};
-

This cannot be separate patch. Conversion is add+remove in one commit,
so even if you remove everything in one patch, it should be then
squashed into patch #9. Anyway, I think better approach is to remove
gradually, so each piece is removed in each converted part.

Best regards,
Krzysztof

This cannot be separate patch. Conversion is add+remove in one commit,
so even if you remove everything in one patch, it should be then
squashed into patch #9. Anyway, I think better approach is to remove
gradually, so each piece is removed in each converted part.

Best regards,
Krzysztof

My comment a about removal of each part of TXT bindings in each patch,
was not addressed. Your approach makes it more difficult to read patches
and makes sense only if each subsystem maintainer will take the patches
(separately). If the patches are going through one tree, then better to
remove the TXT gradually.

So the question - who is going to take each of the patches?

Best regards,
Krzysztof

Hi Krzysztof,

I just understood the context of your comment, will do it in the next version.

Assuming TXT is removed from aggregating TXT - fsl,scu.txt - gradually, do you expect the
removed to be added into the aggregating YAML - fsl,scu.yaml - also gradually within the
same patch ?

Thank you,
Viorel

Each patch making the conversion should remove the piece being
converted. Then finally the patch adding fsl,scu.yaml should remove the
last pieces (remaining ones).

I can take the series through IMX tree if that makes the most sense.

Sounds fine to me. Then however each piece of TXT file should be removed
in each commit doing that piece conversion.

Just sent v7 which removes TXT in each commit which does the conversion.
