v7 cover phy: sunxi: Add Allwinner sun4i USB PHY

This series rework of previous version where it removes legacy usb phy handling and added phy driver on generic-phy framework.

Current implementation phy driver is unable to get pinctrl, clock and reset details from DT since the dm code on these will add it future.

Changes for v7:
- rebase on master

Changes for v6:
- Create private config for passing through driver_data instead directly passing musb_config. This make room for adding new configs in coming patches.
- memset to pdata in musb-new/sunxi.c

Changes for v5:
- Rework of previous series
- Used driver_data on sunxi.c since dt supported
- tested on bpi-m2-plus, orangepi_pc2/prime, bananapi-m64

Changes for v4:
- Rework of previous series
- Add Allwinner sun4i USB PHY driver
- Drop legacy arch/arm/mach-sunxi/usb_phy.c and related code

PATCH v7 3/35 musb: sunxi: Use simple way to fill musb_hdrc pdata

In reply to Jagan Teki

Filling musb_hdrc pdata using structure will unnecessary add extra ifdefs, so fill them inside probe call for better code understanding and get rid ifdefs using devicetree compatible.

PATCH v7 4/35 musb: sunxi: Add fifo config

In reply to Jagan Teki

Unlike other Allwinner SOC's H3/H5/V3s OTG support 4 endpoints with relevant fifo configs, rest all have 5 endpoints. So add the fifo configs and defer them based on driver_data.

PATCH v7 5/35 sunxi: clock: Fix clock gating for H3/H5/A64

In reply to Jagan Teki

clock gating bits on a64 are different than H3_H5, so fixed only required bits on clock_sun6i.h.

Add OTG device clkgate and reset for H3/H5 through driver_data.

Why don't you implement a clock driver for this SoC instead ?

Aren't you asking a bit too much?

Since the first post of these patches, you've asked to rework in a significant manner the driver already, including doing a new PHY driver to use the device model, and making other substantial changes to it.

Jagan complied to all your requests so far, but this one is going to create yet another ton of patches on top of an (already) 35 patches series. And this request comes out of nowhere at the 7th version.

Creating a new clock driver will take a lot of effort, and this really surprise me given that we've had strictly no feedback from you on this considering all the previous SoCs bringups we've done so far.

Add OTG device clkgate and reset for H3/H5 through driver_data.

Why don't you implement a clock driver for this SoC instead ?

Aren't you asking a bit too much?

I am not asking for anything, this is a question, not a request.

I asked why not implement a clock driver and use it just like any other civilized modern driver would instead of digging in the clock controller registers from a USB framework driver (which is icky).

I think that if we are doing some sort of conversion, we should do it completely and properly instead of leaving in hacks like this. A clock driver which allows enabling/disabling clock is probably like what, 2 hour work ? So maybe it's worth investing that time up front to save maintenance burden in the future.

Since the first post of these patches, you've asked to rework in a significant manner the driver already, including doing a new PHY driver to use the device model, and making other substantial changes to it.

Well yes, because it was crap at the beginning and I don't want to see the crap accumulating. It has become much better since, as you can see I only had a few minor comments.

What do you mean by "this" ? I think i did review the previous iterations of this series ? If not, was I on CC ?

I have to admit, I don't really care about the rest of the Allwinner SoC code or what you do there, I only care about the USB part and this poking of clock controller registers seems wrong in a DM/DT driver.

I also don't mind if the clock driver comes later, but I would like to see it happen at some point (soon) to remove this register poking.

This is definitely not a 2 hours job. More like 2 weeks if you want to do it properly, and by which I mean creating the clock driver, converting all the users to it, and then making sure you don't have any regressions.

This is on our radar, but this won't happen overnight.

You did, and thanks a lot for that. The only thing I'm noting is that it's the first time you're being so picky about a series.

You are in a situation of power here. Asking the exact same question when you are the one in power or is a peer doesn't have the same impact, unless you make it clear that it is an actual question and not some way to have it fixed.

I don't have any issue with the end goal, and your willingness to have the code ported over to new APIs. But if from one day to another every maintainer goes like this, this will simply not fly. This is not just about having just a simple clock driver, but also a pinctrl one, and converting all the consumer drivers to the device model, oh, and btw, the DM doesn't fit in the SPL anymore, so we would probably need to do an SPL driver as well. Probably with some painful Kconfig conversions all over the tree even.

This is no longer a simple request, but some huge spaghetti changes that need to be done, mostly by volunteers. And at some point, it just becomes easier to give up, fork, and just maintain our stuff like we were doing before. Or just stop maintaining it entirely. And I'm not sure either situation is something we want.

tl; dr: I'd like some moderation.

Having to deal with code from 2012 everywhere.

This sounds like a massive generalization and an incorrect one to me *.

Since the first post of these patches, you've asked to rework in a significant manner the driver already, including doing a new PHY driver to use the device model, and making other substantial changes to it.

Well yes, because it was crap at the beginning and I don't want to see the crap accumulating. It has become much better since, as you can see I only had a few minor comments.

Quoted 5 lines

And that's totally your role, but at the same time, the point of this series is not to fix the whole world, but rather add support for one particular SoC that is using pretty much the same design than any of our other SoCs' USB phy before. And here we are, 35 patches and counting.

Quoted 4 lines

If I said "yes" to every single patch adding just a minor additional bit of crap to the codebase, we'd be in the state in which we were in 2012, sinking under the boatload of ifdeffery and ad-hoc solutions. So I think some push is needed to avoid that situation.

Quoted 8 lines

I don't have any issue with the end goal, and your willingness to have the code ported over to new APIs. But if from one day to another every maintainer goes like this, this will simply not fly. This is not just about having just a simple clock driver, but also a pinctrl one, and converting all the consumer drivers to the device model, oh, and btw, the DM doesn't fit in the SPL anymore, so we would probably need to do an SPL driver as well. Probably with some painful Kconfig conversions all over the tree even.

You are massively exaggerating right there. I recently did such a conversion for a platform and it didn't take nearly as much effort as you describe and/or it could be well segmented.

Quoted 2 lines

This is no longer a simple request, but some huge spaghetti changes that need to be done, mostly by volunteers.

I am not sure this "volunteers" argument really works in this discussion, since this looks like a commercial contribution to me.

But if you want to discuss volunteering, did you ever consider that I also do the USB maintaining in my free time and the bulk of communication is random people demanding random stuff ? I also don't see people coming up saying "oh, hey, I'll spend some of my own free time to help out maintaining this piece of code". It tends to make people stressed and burnt out ...

Quoted 6 lines

And at some point, it just
becomes easier to give up, fork, and just maintain our stuff like we were doing before. Or just stop maintaining it entirely. And I'm not sure either situation is something we want.

tl; dr: I'd like some moderation.

So much dramatization for a simple question which could've had equally simple answer, really.

Creating a new clock driver will take a lot of effort, and this really surprise me given that we've had strictly no feedback from you on this considering all the previous SoCs bringups we've done so far.

What do you mean by "this" ? I think i did review the previous iterations of this series ? If not, was I on CC ?

You did, and thanks a lot for that. The only thing I'm noting is that it's the first time you're being so picky about a series.

Er, no, I am always picky and hard.

Quoted 6 lines

I appreciate that you have to draw the line somewhere, and when things you want in your subsystem aren't moving as fast as you'd like them to be you have to enforce new rules. But if you were unhappy about something, you never told us, which doesn't seem like a good path forward either. Even in your previous reviews of that particular series.

I think I pointed out pretty much all of it ? If I missed something, it's because it was hidden and didn't surface until the patchset got into some better shape.

And yet, this is the first time you bring up the phy and clock support.

I have to admit, I don't really care about the rest of the Allwinner SoC code or what you do there, I only care about the USB part and this poking of clock controller registers seems wrong in a DM/DT driver.

And I do agree on that. But we also have some history to carry.

I also don't mind if the clock driver comes later, but I would like to see it happen at some point (soon) to remove this register poking.

Is this going to happen at some point ?

At some point, yes, but I can't give you a deadline.

That usually means never, sadly (and see * above).

rmobile? The scale isn't quite the same. It looks like there's 4 similar SoCs, with a dozen of boards supported. We have a dozen of SoCs supported, and around 120-130 boards. The clock tree looks much simpler too, and it seems like it has less drivers.

And I don't really know what the constraints are on the SPL side, but it's really tight on our end. So maybe I'm exagerating, but you're definitely understating it too.

PATCH v7 6/35 musb: sunxi: Add OTG device clkgate and reset for H3/H5

In reply to Marek Vasut

Hi Marek,

Quoted 6 lines · Marek Vasut
Quoted 3 lines · Jagan Teki

Add OTG device clkgate and reset for H3/H5 through driver_data.

Why don't you implement a clock driver for this SoC instead ?

As of now we are unable to get pinctrl, clock and reset details from DT since the dm code on these will add it in future and the same I have mentioned in the cover-letter patch. Since Allwinner is big SOC's collection along with numerous amount of boards, and shortage of binary size (with few SOC's) we need to be careful while adding these features and which obviously taking some amount of time. Hope you understand.

Jagan.

PATCH v7 10/35 phy: Add Allwinner A64 USB PHY driver

In reply to Jagan Teki

USB PHY implementation for Allwinner SOC's can be handling in to single driver with different phy configs.

This driver handle all Allwinner USB PHY's start from 4I to 50I(except 9I). Currently added A64 compatibility more will add in next coming patches.

Current implementation is unable to get pinctrl, clock and reset details from DT since the dm code on these will add it future.

Driver named as phy-sun4i-usb.c since the same PHY logic work for all Allwinner SOC's start from 4I to A64 except 9I with different phy configurations.

PATCH v7 14/35 phy: sun4i-usb: Add A83T USB PHY config

In reply to Jagan Teki

Unlike, other Allwinner SUN4I Phy supporting SOC, A83T has 2 USB PHY's and second one is HSIC. So phy control need to configure to handle these HSIC and SIDDQ requirement.

PATCH v7 21/35 phy: sun4i-usb: Add a sunxi specific function for setting squelch-detect

In reply to Jagan Teki

The sunxi otg phy has a bug where it wrongly detects a high speed squelch when reset on the root port gets de-asserted with a lo-speed device.

The workaround for this is to disable squelch detect before de-asserting reset, and re-enabling it after the reset de-assert is done. Add a sunxi specific phy function to allow the sunxi-musb glue to do this.

Allwinner PHY USB code is now part of generic-phy framework, so drop existing legacy handling like arch/arm/mach-sunxi.c and related code areas.

v7 cover phy: sunxi: Add Allwinner sun4i USB PHY

In reply to Jagan Teki

Hi Jun,

Quoted 64 lines · Jagan Teki

This series rework of previous version where it removes legacy usb phy handling and added phy driver on generic-phy framework.

Current implementation phy driver is unable to get pinctrl, clock and reset details from DT since the dm code on these will add it future.

Changes for v7:
- rebase on master

Changes for v6:
- Create private config for passing through driver_data instead directly passing musb_config. This make room for adding new configs in coming patches.
- memset to pdata in musb-new/sunxi.c

Changes for v5:
- Rework of previous series
- Used driver_data on sunxi.c since dt supported
- tested on bpi-m2-plus, orangepi_pc2/prime, bananapi-m64

Changes for v4:
- Rework of previous series
- Add Allwinner sun4i USB PHY driver
- Drop legacy arch/arm/mach-sunxi/usb_phy.c and related code
