From: Sebastian Reichel <[email protected]>
Hi,
This adds adds support for the UNI-T UTi260B thermal camera, which is
based on i.MX6ULL. Patches 1-11 clean up all warnings reported by
CHECK_DTBS for i.MX6ULL (i.e. for an empty board). They are not specific
to the UTi260B and in fact that machine has most of the IP handled by
these patches marked as disabled. Then patches 12+13 introduce the vendor
and board compatible DT bindings. Finally the last patches adds support
for the thermal camera itself.
The DT is based on reverse engineered information. More information about
the device can be found in this presentation from Embedded Recipes 2023:
* https://embedded-recipes.org/2023/wp-content/uploads/2023/10/Running-FOSS-on-a-Thermal-Camera-Sebastian-Reichel-compressed.pdf
* https://www.youtube.com/watch?v=uvObsCG-Cqo
I also prepared a branch with these patches (and a minimal kernel config)
and published it here:
https://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-misc.git/log/?h=uti260b

-Device tree bindings for i.MX Wireless External Interface Module (WEIM)
-
-The term "wireless" does not imply that the WEIM is literally an interface
-without wires. It simply means that this module was originally designed for
-wireless and mobile applications that use low-power technology.
-
-The actual devices are instantiated from the child nodes of a WEIM node.
-
-Required properties:
-
- - compatible: Should contain one of the following:
- "fsl,imx1-weim"
- "fsl,imx27-weim"
- "fsl,imx51-weim"
- "fsl,imx50-weim"
- "fsl,imx6q-weim"
- - reg: A resource specifier for the register space
- (see the example below)
- - clocks: the clock, see the example below.
- - #address-cells: Must be set to 2 to allow memory address translation
- - #size-cells: Must be set to 1 to allow CS address passing
- - ranges: Must be set up to reflect the memory layout with four
- integer values for each chip-select line in use:
-
- <cs-number> 0 <physical address of mapping> <size>
-
-Optional properties:
-
- - fsl,weim-cs-gpr: For "fsl,imx50-weim" and "fsl,imx6q-weim" type of
- devices, it should be the phandle to the system General
- Purpose Register controller that contains WEIM CS GPR
- register, e.g. IOMUXC_GPR1 on i.MX6Q. IOMUXC_GPR1[11:0]
- should be set up as one of the following 4 possible
- values depending on the CS space configuration.
-
- IOMUXC_GPR1[11:0] CS0 CS1 CS2 CS3
- ---------------------------------------------
- 05 128M 0M 0M 0M
- 033 64M 64M 0M 0M
- 0113 64M 32M 32M 0M
- 01111 32M 32M 32M 32M
-
- In case that the property is absent, the reset value or
- what bootloader sets up in IOMUXC_GPR1[11:0] will be
- used.
-
- - fsl,burst-clk-enable For "fsl,imx50-weim" and "fsl,imx6q-weim" type of
- devices, the presence of this property indicates that
- the weim bus should operate in Burst Clock Mode.
-
- - fsl,continuous-burst-clk Make Burst Clock to output continuous clock.
- Without this option Burst Clock will output clock
- only when necessary. This takes effect only if
- "fsl,burst-clk-enable" is set.
-
-Timing property for child nodes. It is mandatory, not optional.
-
- - fsl,weim-cs-timing: The timing array, contains timing values for the
- child node. We get the CS indexes from the address
- ranges in the child node's "reg" property.
- The number of registers depends on the selected chip:
- For i.MX1, i.MX21 ("fsl,imx1-weim") there are two
- registers: CSxU, CSxL.
- For i.MX25, i.MX27, i.MX31 and i.MX35 ("fsl,imx27-weim")
- there are three registers: CSCRxU, CSCRxL, CSCRxA.
- For i.MX50, i.MX53 ("fsl,imx50-weim"),
- i.MX51 ("fsl,imx51-weim") and i.MX6Q ("fsl,imx6q-weim")
- there are six registers: CSxGCR1, CSxGCR2, CSxRCR1,
- CSxRCR2, CSxWCR1, CSxWCR2.
-
-Example for an imx6q-sabreauto board, the NOR flash connected to the WEIM:
-
- weim: weim@21b8000 {
- compatible = "fsl,imx6q-weim";
- reg = <0x021b8000 0x4000>;
- clocks = <&clks 196>;
- #address-cells = <2>;
- #size-cells = <1>;
- ranges = <0 0 0x08000000 0x08000000>;
- fsl,weim-cs-gpr = <&gpr>;
-
- nor@0,0 {
- compatible = "cfi-flash";
- reg = <0 0 0x02000000>;
- #address-cells = <1>;
- #size-cells = <1>;
- bank-width = <2>;
- fsl,weim-cs-timing = <0x00620081 0x00000001 0x1c022000
- 0x0000c000 0x1404a38e 0x00000000>;
- };
- };
-
-Example for an imx6q-based board, a multi-chipselect device connected to WEIM:
-
-In this case, both chip select 0 and 1 will be configured with the same timing
-array values.
-
- weim: weim@21b8000 {
- compatible = "fsl,imx6q-weim";
- reg = <0x021b8000 0x4000>;
- clocks = <&clks 196>;
- #address-cells = <2>;
- #size-cells = <1>;

HDMI Audio has been added to the DT binding documentation with an
incorrect index. DT and the driver use index 26. This happened,
because the binding is missing MULTI_SAI type, which is using
index 25.

i.MX6UL(L) uses "fsl,imx6sx-lcdif" as fallback compatible string,
but has only very lightweight DISPLAY power domain. Its DISPLAY
power domain is not supported by the binding / Linux kernel at
the moment. Since the current setup is working, let's remove the
power-domain from being required for that platform to fix the warning
printed by CHECK_DTBS=y.

-Freescale Asynchronous Sample Rate Converter (ASRC) Controller
-
-The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of a
-signal associated with an input clock into a signal associated with a different
-output clock. The driver currently works as a Front End of DPCM with other Back
-Ends Audio controller such as ESAI, SSI and SAI. It has three pairs to support
-three substreams within totally 10 channels.
-
-Required properties:
-
- - compatible : Compatible list, should contain one of the following
- compatibles:
- "fsl,imx35-asrc",
- "fsl,imx53-asrc",
- "fsl,imx8qm-asrc",
- "fsl,imx8qxp-asrc",
-
- - reg : Offset and length of the register set for the device.
-
- - interrupts : Contains the spdif interrupt.
-
- - dmas : Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-
- - dma-names : Contains "rxa", "rxb", "rxc", "txa", "txb" and "txc".
-
- - clocks : Contains an entry for each entry in clock-names.
-
- - clock-names : Contains the following entries
- "mem" Peripheral access clock to access registers.
- "ipg" Peripheral clock to driver module.
- "asrck_<0-f>" Clock sources for input and output clock.
- "spba" The spba clock is required when ASRC is placed as a
- bus slave of the Shared Peripheral Bus and when two
- or more bus masters (CPU, DMA or DSP) try to access
- it. This property is optional depending on the SoC
- design.
-
- - fsl,asrc-rate : Defines a mutual sample rate used by DPCM Back Ends.
-
- - fsl,asrc-width : Defines a mutual sample width used by DPCM Back Ends.
-
- - fsl,asrc-clk-map : Defines clock map used in driver. which is required
- by imx8qm/imx8qxp platform
- <0> - select the map for asrc0 in imx8qm/imx8qxp
- <1> - select the map for asrc1 in imx8qm/imx8qxp
-
-Optional properties:
-
- - big-endian : If this property is absent, the little endian mode
- will be in use as default. Otherwise, the big endian
- mode will be in use for all the device registers.
-
- - fsl,asrc-format : Defines a mutual sample format used by DPCM Back
- Ends, which can replace the fsl,asrc-width.
- The value is 2 (S16_LE), or 6 (S24_LE).
-
-Example:
-

+ The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of
+ a signal associated with an input clock into a signal associated with a
+ different output clock. The driver currently works as a Front End of DPCM
+ with other Back Ends Audio controller such as ESAI, SSI and SAI. It has
+ three pairs to support three substreams within totally 10 channels.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

This patchset does not do what I asked to, but maybe that's just
coincidence that you send conversion now.

If the product name is "uti260b", then it is enough "uni-t,uti260b". If
you added the imx part because there is a SoM, then it is anyway not
correct representation of the SoM.

That's confusing. The imx-thermal has phandle to anatop and is a child
of it. Please sort it out, e.g. deprecate one way.

Time seems like something humans can grasp, so why using hexadecimal

This should fail the testing - judging by Rob's reports, you did not

Would be nice to place a comment above this, which mentions the intended

i'm not sure this is a good idea. In case i.MX6UL(L) is different from
i.MX6SX here, then it should have a different compatible.

The nodename must be unique. So just "regulator" does not work. In
the past this was sometimes solved by adding something like @0,
which is part of the nodename. But that is not ok, since there is no
reg property.

I just used something slow, which should definitely work. I will try
to increase to 1MHz. Note, that the display is not driven via SPI.
SPI is just used for the configuration.
Thanks for the review,

It already has. The i.MX6UL(L) compatible looks like this:
compatible = "fsl,imx6ul-lcdif", "fsl,imx6sx-lcdif"
So the i.MX6SX one is just a fallback compatible. But the current
requirement for power-domains affects i.MX6UL(L), since it says
the compatible only needs to contain "fsl,imx6sx-lcdif" somewhere
to make power-domains mandatory.
Note, that the kernel driver does not use "fsl,imx6ul-lcdif", so
the hardware itself is indeed compatible.

I used "memory-controller", which is what the other bindings in
memory-controller use.

Thanks for clarification. Yes, 1 MHz would be better.

thanks, i misunderstood the commit message. I thought this was a
i.MX6UL(L) specific issue and the i.MX6SX is slightly different. In the
past the fallback compatible was sometimes abused.
So everything makes sense now.
