[PATCH 0/6] arm64: dts: freescale: imx8mp-verdin: Add Toradex Capacitive Touch Display 10.1" LVDS V1 and V2

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@toradex.com>

This series adds device tree overlays for the Toradex Capacitive Touch
Display 10.1" LVDS V1 and V2 with the Verdin iMX8M Plus SoM.

The display addition covers two interface types:

- Native LCDIF (LVDS)
- DSI-to-LVDS adapter based on the SN65DSI84

This change depends on other patch series, and should be applied after
it:

- https://lore.kernel.org/linux-arm-kernel/20260623195741.495734-1-leoreis.costa@gmail.com/T/#t

  Adds the Toradex Capacitive Touch Display 10.1" LVDS V2 overlays for
  the Verdin AM62. This series is required because it adds the panel
  bindings for the display. It is currently in linux-next.

[PATCH 1/6] arm64: dts: freescale: imx8mp-verdin: Add Toradex Capacitive Touch Display 10.1" LVDS

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@toradex.com>

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
LVDS connected via Verdin iMX8M Plus LCDIF on carrier boards exposing LVDS
interface (e.g., Mallow). The panel is a LogicTechno LT170410-2WHC 10.1"
WXGA IPS LCD and the touch input is provided by an Atmel MaxTouch
capacitive touch controller.

[PATCH 2/6] arm64: dts: freescale: imx8mp-verdin: Add Toradex DSI to LVDS adapter with 10.1" display

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@toradex.com>

Add a device tree overlay for the Toradex DSI to LVDS Adapter with the
Toradex Capacitive Touch Display 10.1" LVDS. The adapter connects to the
Verdin DSI_1 interface. It is based on the Texas Instruments SN65DSI84
DSI-to-LVDS bridge and drives a LogicTechno LT170410-2WHC 10.1" WXGA LVDS
panel. Touch input is provided by an Atmel MaxTouch capacitive touch
controller.

[PATCH 3/6] arm64: dts: freescale: imx8mp-verdin: Add Mezzanine with Toradex Display 10.1" LVDS

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@toradex.com>

Add a device tree overlay enabling the Toradex Capacitive Touch Display
10.1" LVDS on the Verdin Development Board with Verdin iMX8M Plus
Mezzanine expansion board. The panel connects via the i.MX8M Plus LCDIF
on the Mezzanine LVDS interface (J10). The panel is a LogicTechno
LT170410-2WHC 10.1" WXGA IPS LCD and the touch input is provided by an
Atmel MaxTouch capacitive touch controller.

[PATCH 4/6] arm64: dts: freescale: imx8mp-verdin: Add Toradex Capacitive Touch Display 10.1" LVDS V2

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@toradex.com>

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
LVDS V2 connected via Verdin iMX8M Plus LCDIF on carrier boards exposing
LVDS interface (e.g., Mallow). The panel is an Opto Logic
SCX1001511GGC49 10.1" WXGA TFT LCD and the touch input is provided by an
ILITEK ILI251x capacitive touch controller.

[PATCH 5/6] arm64: dts: freescale: imx8mp-verdin: Add Toradex DSI to LVDS adapter with the 10.1" V2 display

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@toradex.com>

Add a device tree overlay for the Toradex DSI to LVDS Adapter with the
Toradex Capacitive Touch Display 10.1" LVDS V2. The adapter connects to the
Verdin DSI_1 interface. It is based on the Texas Instruments SN65DSI84
DSI-to-LVDS bridge and drives an Opto Logic SCX1001511GGC49 10.1" WXGA TFT
LCD LVDS panel. Touch input is provided by an ILITEK ILI251x capacitive
touch controller.

[PATCH 6/6] arm64: dts: freescale: imx8mp-verdin: Add Mezzanine with Toradex Display 10.1" LVDS V2

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@toradex.com>

Add a device tree overlay enabling the Toradex Capacitive Touch Display
10.1" LVDS V2 on the Verdin Development Board with Verdin iMX8M Plus
Mezzanine expansion board. The panel connects via the i.MX8M Plus LCDIF
on the Mezzanine LVDS interface (J10). The panel is an Opto Logic
SCX1001511GGC49 10.1" WXGA TFT LCD LVDS and the touch input is provided
by an ILITEK ILI251x capacitive touch controller.

Hi Frank,

There are two main differences:

1. The mezzanine one uses different backlight controll pins, so here we
use the 'backlight-mezzanine' node, instead of the 'backlight' one, used
in the one without the mezzanine.

2. The touchscreen GPIO and interrupt pins are also different with the
mezzanine board.

And there are for imx8mm
https://lore.kernel.org/imx/20260724-v1-verdin-imx8mm-dtbos-v2-3-9d7988bd76f6@toradex.com/

https://lore.kernel.org/imx/sr26lfvwasgcosfzcf4ydtwxwjjutlio2yqpgxldatpzjo7e4y@77k7gefnjzvl/

Any ways, it is too late for 7.3, we have enough time for 7.4 to discuss
work on optimization solution.

If use nexus connectors, we can share one dtso now if there are not
clock settings.

clock patches is close to pick up

Hi Frank,

I tried implementing the nexus connectors in imx8mp-verdin-wifi-dev.dts, and
modify the Mezzanine overlay for the LVDS V2 display to do an initial test
(diff with the changes at the end of the email). They worked partially, but it
introduced an issue where the drivers come up much later. Before, the drivers
relevant for the display (in this case, LCDIF and the touch controller
specifically) came up at around ~8s. After introducing the nexus connector they
come up at around ~20s, after the board has already booted (complete logs at
https://paste.debian.net/hidden/81acfa7d):

    [   21.008400] input: ILI210x Touchscreen as /devices/platform/soc@0/30800000.bus/30a30000.i2c/i2c-1/1-0041/input/input3
    [   21.014785] [drm] Initialized imx-lcdif 1.0.0 for 32e90000.display-controller on minor 2
    [   21.029634] Console: switching to colour frame buffer device 160x50
    [   21.029823] imx-lcdif 32e90000.display-controller: [drm] fb0: imx-lcdifdrmfb frame buffer device
    [   21.031376] imx8m-blk-ctrl 32ec0000.blk-ctrl: sync_state() pending due to 32e30000.dwe

Was this behavior observed before? It may have not been noticed, since the
drivers do come up at some point, and it may not be an issue for other
interfaces, or they may actually come up earlier in other cases. In our case
this is important though, since visual feedback from the display is expected
early.

It seems that the drivers are being deferred at boot start by the
device_links_check_suppliers() function. It runs through the drivers before
they're initialized and defers them if their suppliers are not available. The
GPIO and PWM drivers are able to follow the gpio-map and pwm-map properties
(through the of_parse_phandle_with_args_map() function), but from what I see,
device_links_check_suppliers() has no such mechanism. It follows the phandle to
the nexus connector node only, and since there's no compatible driver for it,
the function defers the consumer drivers used in the overlay.

I think this is what is happening mainly because setting the
fw_devlink=permissive kernel parameter (which sets the DL_FLAG_SYNC_STATE_ONLY
flag) solved the issue, though I could be misunderstanding something.

	int device_links_check_suppliers(struct device *dev)
	{
		...
		list_for_each_entry(link, &dev->links.suppliers, c_node) {
			...

			if (link->status != DL_STATE_AVAILABLE &&
			    !device_link_test(link, DL_FLAG_SYNC_STATE_ONLY)) {

				...
				device_links_missing_supplier(dev);
				ret = dev_err_probe(dev, -EPROBE_DEFER,
						    "supplier %s not ready\n", dev_name(link->supplier));
				break;
			}
			WRITE_ONCE(link->status, DL_STATE_CONSUMER_PROBE);
		}
		...
	}

Has this behavior been observed before? Do you know of any work being done that
addresses this?

See below the changes that I made for this test, relative to my last patch
(only a draft):

Thank you for working on this.

Understand, we have not notified this problem before.

Does a dummy container driver (for debug) to proof your analyer?  Let
me to find time to debug it.
