cover *** ARM: Update arch-vt8500 to Devicetree ***

This patchset updates arch-vt8500 to devicetree and removes all the old-style code. Support for WM8650 has also been added.

Example dts/dtsi files are given for the three currently supported models.

Major changes:

GPIO code has been converted to a platform_device and rewritten as WM8505 support was broken. Add support for WM8650 gpio controller.

UHCI support was missing. Added this as a generic non-pci uhci controller as it doesn't require anything special. Should be usable by any system that doesn't have special requirements to get the UHCI controller working.

Framebuffer code patched to support WM8650. The bindings for this are of concern but there doesn't seem to be a formalized binding yet. This patch is based off Sascha Hauer's current patch on the dri-devel mailing list and should be easily patched out when its finalized.

Patchset based on Arnd's arm-soc/for-next branch.

Could I get this reviewed, hopefully for inclusion into v3.7.

Regards
Tony Prisk

Add device tree files for VT8500, WM8505 and WM8650 SoC's and reference boards.
arch/arm/boot/dts/vt8500_ref.dts +0 -0

It appears more typical to use "-" rather than "_" in the filename to join SoC and board names.

I guess "_ref" means "reference". Is that how the boards are commonly known? Are you sure there will never be another reference board for these SoCs? Given the "model" values in the file, something more like vt8500-bv07.dts might be more appropriate?

Maybe it's better to just hold off on adding this node, to wait until the binding is complete so this file doesn't churn? Certainly it sounded like Sascha was going to change the binding a little in response to comments it received.

I'm fairly certain there will never be another reference board, as these SoC's seem to disappear after a few months and a new one comes out. Most of the models are chinese in origin with no real identifying names. Having said that, I have renamed the dts files to a less 'generic' name. vt8500-bv07.dts, wm8850-mid.dts.
wm8505-ref is the same as I can't find any other identification for it, and everyone else I've had contact with who has one has the same board design.

My understanding with Sascha's patch is that it won't include a pixel format property and therefore we won't be able to use his binding properly until its revisited. Without this node, we have no display output available other than uart - and that's only available if you modify the hardware.

This patchset will make arch-vt8500 nearly unusable without this node as we would have to leave the framebuffer code out as well.

Always open to suggestions,

Regards

I believe that using hard-coded node names is frowned upon. Better would be to put a phandle into the display controller's node that points at the node representing the display, e.g.:

    fb at d800e400 {
        compatible = "via,vt8500-fb";
        reg = <0xd800e400 0x400>;
        interrupts = <12>;
        via,display = <&display>;
    };
    display: display {
        ...

The patch consisted of changing one value in one line and is commented in the source. I didn't think it justified a separate patch as it has been thoroughly tested and is unlikely to cause any problems.

PATCH 6/8 arm: vt8500: Update arch-vt8500 to devicetree support.

In reply to Tony Prisk

Merged existing board files to a single dt-capable file. Converted irq and timer code to devicetree.
Removed existing device files that are no longer required with devicetree support.
All existing platform devices are converted to devicetree nodes except GPIO and PWM.

GPIO support was limited to VT8500 (non-working on WM8505).

Removed restart.c and moved code into vt8500.c to remove duplicate PMC code.

That looks quite suspicious. What's it doing? Is this something that should be part of a pinctrl driver, or the GPIO driver?

PATCH 6/8 arm: vt8500: Update arch-vt8500 to devicetree support.

Quoted 11 lines · Tony Prisk

Quoted 7 lines
Merged existing board files to a single dt-capable file. Converted irq and timer code to devicetree.
Removed existing device files that are no longer required with devicetree support.
All existing platform devices are converted to devicetree nodes except GPIO and PWM.
Perhaps that also explains what I was commenting on in the GPIO driver patch. Why not convert GPIO too?

GPIO was converted - I hadn't planned on doing it, but apparently I did it anyway :/ Comment is now removed from the commit message.

That looks quite suspicious. What's it doing? Is this something that should be part of a pinctrl driver, or the GPIO driver?

This code is carried over from the original implementation but converted for device tree. It should be part of a pinctrl driver, but we don't have one. It is basically selecting between CCIR or LCD.

Annoyingly, the bit-fields changed between models, so we have it twice, once for each framebuffer driver. It needs to check for compatible nodes so that it only applies the setting for the framebuffer type being requested by the dts because of the conflicting bit-fields.

PATCH 7/8 arm: vt8500: doc: Add device tree bindings for arch-vt8500 devices

In reply to Tony Prisk

Bindings for gpio, interrupt controller, power management controller, timer, realtime clock, serial uart, ehci and uhci controllers and framebuffer controllers used on the arch-vt8500 platform.

Framebuffer binding also specifies a 'display' node which is required for determining the lcd panel data.

What on earth are all those magic numbers?

I *guess* they're enabling some default GPIO settings etc.

But it really needs better structure, #defines for each one or atleast include <linux/bitops.h> and say:

= BIT(4) | /* Enable GPIO pin 5 on this bank */
BIT(5); /* Enable GPIO pin 6 on this bank */

However I suspect this is board specific and should be taken from device tree. Please elaborate on this...

Ditto for the different instances.

What on earth are all those magic numbers?
I *guess* they're enabling some default GPIO settings etc.

No, they are the register offsets you quoted above, per bank. There is no easy way to abstract these, and I suggested putting the values into the source code rather than describing each bank separately in the .dtsi file.

My feeling however is that the "vt8500_chip->regoff" is wrong, which would mean only the first bank works. The code adds the same offsets per bank once more that it sets in this bank table.

Aha I was fooled by this:

+struct vt8500_gpio_bank_regs {

+       int     en;
+       int     dir;
+       int     data_out;
+       int     data_in;
+       int     ngpio;

+};

This needs to be named something intuitive like "vt8500_gpio_bank_regoffsets"

Some kerneldoc intsead of the opaque comment above will also improve readability a lot:

/**
* struct vt8500_gpio_bank_regoffsets
* @en: offset to enable register in the bank
* ...

Oh.. Thanks for picking that up Arnd. You are absolutely correct. I have removed the references for ->regoff. Left over from old code.

Converted the existing arch-vt8500 gpio to a platform_device. Added support for WM8505 and WM8650 GPIO controllers.

Can't you use pdev->dev.of_node instead of searching for it again?

I think that's all just:

module_platform_driver(vt8500_gpio_driver);

(except that _init uses platform_driver_probe() rather than platform_driver_register(), which seems unusual. I guess that explains the of_find_matching_node() above too.)

That should be "GPL v2" given the license header.

Ah, I totally missed both of these. Using platform_driver_register is definitely preferred over platform_driver_probe in cases like this, so using module_platform_driver is the right simplification.

In reply to Tony Prisk

Apologies for the formatting/style errors. Thought I had checkpatch'd these but missed a few (especially the uhci patch). All formatting errors returned by scripts/checkpatch.pl are now fixed locally.

Apologies again,

cover *** ARM: Update arch-vt8500 to Devicetree ***

In reply to Tony Prisk

These patches can be used directly on kernel.org's main tarballs? Or just on gitorious/vt8500 ?

Quoted 136 lines · Tony Prisk

This patchset updates arch-vt8500 to devicetree and removes all the old-style
code. Support for WM8650 has also been added.

Example dts/dtsi files are given for the three currently supported models.

Major changes:

GPIO code has been converted to a platform_device and rewritten as WM8505 support was broken. Add support for WM8650 gpio controller.

UHCI support was missing. Added this as a generic non-pci uhci controller as
it doesn't require anything special. Should be usable by any system that doesn't
have special requirements to get the UHCI controller working.

Framebuffer code patched to support WM8650. The bindings for this are of concern
but there doesn't seem to be a formalized binding yet. This patch is based off
Sascha Hauer's current patch on the dri-devel mailing list and should be easily
patched out when its finalized.

Patchset based on Arnd's arm-soc/for-next branch.

Could I get this reviewed, hopefully for inclusion into v3.7.

Tony Prisk
