Subject: [PATCH v6 0/3] Move mediatek system clock reset to reset folder

This series move mediatek system clock reset to drivers/reset/mediatek.

Changes for v6:
1. Separate patches.
a. Move data and drivers to reset/mediatek.
b. Implement auxiliary bus driver in clk/mediatek/clk-mtk.c.
c. Implement auxiliary bus interface in reset/mediatek.
2. This version is based on 6.1-rc1.

Changes for v5:
1. Replace reset-mtxxxx.h with reset-mtxxxx.c and after using this,
we don't need to add many "#if #endif" in reset-mediatek-sysclk.c.
2. Use mediatek clock common KConfig to control whether to build in
reset-mtxxxx.c.
3. Rebased on linux-next-1007.

Changes for v4:
1. Rebased oo linux-next-1004.
2. Move reset data which are scattered around the mediatek drivers to
reset-mtxxxx.h.
3. Add reset data of mt6795.

Version for this series:
v5 : https://lore.kernel.org/all/[email protected]/
v4 : https://lore.kernel.org/all/[email protected]/
v3 : https://lore.kernel.org/all/[email protected]/
v2 : https://lore.kernel.org/all/[email protected]/

Subject: [PATCH v6 2/3] clk: mediatek: Add auxiliary bus support for sysclk reset

To see the relationship in sysfs between devices and they're "real"
device drivers for the reset component of the device:

- Add auxiliary bus support for sysclk reset.
- Change to use the mtk_reset_controller_register() to register sysclk
reset for mediatek clock drivers using device.

Subject: [PATCH v6 1/3] reset: mediatek: Move MediaTek system clock reset to reset/mediatek

To manager MediaTek system clock reset easier, we move the driver to
drivers/reset/mediatek.

- Create reset/mediatek folder.
- Move clk/mediatek/reset.c to reset/mediatek/reset-mediatek-sysclk.c
- Because we don't want to build in unsed static variable, we use clk
KConfig to separate them. For example, when we use MT8186, we don't
want to build in the static constants for MT8195.
- Move reset data which are scattered around the mediatek drivers to
reset-mtxxxx.c.
- There are two version for mtk_reset_init because some mediatek clock
drivers (mt8135 and mt8173) are using device_node instead of device,
so we need to add two version for the init function.

I'd be more for

obj-$(CONFIG_ARCH_MEDIATEK) += mediatek/

as there's no reason to even compile these if MTK support isn't enabled at all.

Why do we have this "clk_mt8135." prefix here (and also mt8173), when all of
the others don't have any prefix?

That's not consistent and shall be changed, unless there's a valid reason not to.

Is this really informative?
There's sysfs telling you infos about drivers that has been (or hasn't been yet)
registered... so, please change that to a pr_debug() instead.

Apart from that, looks good.

Can we have devm_auxiliary_device_add() that sets the parent and
registers the device?

Hello Angelo,

thanks for your review.
I obj-y += mediatek/ because if I don't write like this, it will build
fail for x86.
Is there any suggestion for this?

The reason I rename it as this because the limitation of name in
struct auxiliary_device_id. It's 32. The
KBUILD_MODNAME "clk_mt6795_infracfg" and "clk_mt6795_pericfg" is fixed,
so I need to modify the device_name.

I do this because in patch [3/3], other name will be added
KBUILD_MODNAME and for 8135 and 8173, we can not use the aux bus
interface because there is no have not device provided by them.

Hello Stephen,

I can't find the definition of devm_auxiliary_device_add(). Is there
any information for this function?

From the errors it seems like you're compiling the clock drivers (like
clk-mt8135.c) but not the sysclk reset driver (reset-mediatek-sysclk.c). Given
that this happened when you added CONFIG_ARCH_MEDIATEK to that Makefile, then it
must mean that that config is disabled, which would make sense for a x86 build.
But then the fact that the clock driver was built even in this case must mean
that you have COMPILE_TEST enabled.

I guess in order to have a working COMPILE_TEST=y build, you do need to have
obj-y += mediatek/, and on the Kconfig below...

... have instead

if ARCH_MEDIATEK || COMPILE_TEST

I think that should fix the issue.
