Please drop this commit. Adding a mdp3-mutex compatible is not needed here.

Thanks for checking. We probably would need a fallback compatible. We can only 
know from the HW engineers that can confirm if the IP block is the same as the 
disp mutex or a different one.

I'll drop both patches for now until things got clear.

Matthias

They're located in a different iospace from each other, but either the platform
data needs to *not be* joined together, or if they're together, I would not like
having two different compatible strings for essentially the same thing.

I would at this point prefer dropping '-disp' from 'mediatek,mt8186-disp-mutex'
so that we would be able to declare two 'mediatek,mt8186-mutex' in devicetree...
...or simply have two mediatek,mt8186-disp-mutex (although logically incorrect?).

Angelo

Thanks for your opinion.

They are two different hardwares for different address spaces. 

I think we drop '-disp' from 'mediatek,mt8186-disp-mutex' will be
excessive because we also need to modify mutex node in all exited dts
files.

I prefer havingg two mediatek,mt8186-disp-mutex. 

ex:
mutex: mutex@14001000 {
	compatible = "mediatek,mt8186-disp-mutex";
	..
}

mdp3_mutex0: mutex@1b001000 {
	compatible = "mediatek,mt8186-disp-mutex";
	...
}

What do you think?

Allen

I'm a bit undecided instead, now... because from what I understand now,
the platform data fields

	.mutex_mod  and  .mutex_sof

are *not valid* for mutex at 0x1b001000 but only for the instance at 0x14001000.

If we go this way, at this point, we would be free (and allowed by the driver)
to try to set these for 0x1b001000, and to try to set MDP3 table paths on
0x14001000, which is something that shouldn't be logically allowed, as the
hardware does *not* support that.

Unless I got that wrong, and these fields for MUTEX_MOD_DISP_xxxx do exist in
the mutex instance at 0xb001000, in which case, I fully agree with Matthias.

But otherwise, I have my doubts.

Angelo

I got your point. 

The disp and mdp3 drivers work with the same data field beacase 
14001000 (disp mutex) would not use .mutex_table_mod and 1b001000 (mdp3
mutex) would not use .mutex_mod/.mutex_sof.


How about ...

static const struct mtk_mutex_data mt8186_mutex_driver_data = {
	.mutex_mod = mt8186_mutex_mod,
	.mutex_sof = mt8186_mutex_sof,
	.mutex_mod_reg = MT8183_MUTEX0_MOD0,
	.mutex_sof_reg = MT8183_MUTEX0_SOF0,
};

static const struct mtk_mutex_data mt8186_mutex_mdp_driver_data = {
	.mutex_table_mod = mt8186_mutex_table_mod,
};

{ .compatible = "mediatek,mt8186-disp-mutex",
.data = &mt8186_mutex_driver_data},
{ .compatible = "mediatek,mt8186-mdp3-mutex",
.data = &mt8186_mutex_mdp_driver_data},


 mutex: mutex@14001000 {
    compatible = "mediatek,mt8186-disp-mutex";
    ..
 }
 mdp3_mutex0: mutex@1b001000 {
    compatible = "mediatek,mt8186-mdp3-mutex";
    ...
 }

Do you think that is feasible?

I got your point. 

The disp and mdp3 drivers work with the same data field beacase 
14001000 (disp mutex) would not use .mutex_table_mod and 1b001000 (mdp3
mutex) would not use .mutex_mod/.mutex_sof.


How about ...

static const struct mtk_mutex_data mt8186_mutex_driver_data = {
	.mutex_mod = mt8186_mutex_mod,
	.mutex_sof = mt8186_mutex_sof,
	.mutex_mod_reg = MT8183_MUTEX0_MOD0,
	.mutex_sof_reg = MT8183_MUTEX0_SOF0,
};

static const struct mtk_mutex_data mt8186_mutex_mdp_driver_data = {
	.mutex_table_mod = mt8186_mutex_table_mod,
};

{ .compatible = "mediatek,mt8186-disp-mutex",
.data = &mt8186_mutex_driver_data},
{ .compatible = "mediatek,mt8186-mdp3-mutex",
.data = &mt8186_mutex_mdp_driver_data},


 mutex: mutex@14001000 {
    compatible = "mediatek,mt8186-disp-mutex";
    ..
 }
 mdp3_mutex0: mutex@1b001000 {
    compatible = "mediatek,mt8186-mdp3-mutex";
    ...
 }

Do you think that is feasible?

This makes a lot more sense to me.

Though, you have to also add the mod and sof regs, because the mutex instance
for MDP_MUTEX does have these registers, even though they are used for different
mods/sofs.

static const struct mtk_mutex_data mt8186_mutex_driver_data = {
	.mutex_mod = mt8186_mutex_mod,
	.mutex_sof = mt8186_mutex_sof,
	.mutex_mod_reg = MT8183_MUTEX0_MOD0,
	.mutex_sof_reg = MT8183_MUTEX0_SOF0,
};

static const struct mtk_mutex_data mt8186_mdp_mutex_driver_data = {
  	.mutex_mod_reg = MT8183_MUTEX0_MOD0,
  	.mutex_sof_reg = MT8183_MUTEX0_SOF0,
	.mutex_table_mod = mt8186_mdp_mutex_table_mod,
};

P.S.: Notice that mt8186_mdp_mutex_driver_data instead of
       mt8186_mutex_mdp_driver_data was chosen on purpose:
       like that, we're referencing to real block names.

Though, you have to also add the mod and sof regs, because the mutex instance
for MDP_MUTEX does have these registers, even though they are used for different
mods/sofs.

static const struct mtk_mutex_data mt8186_mutex_driver_data = {
	.mutex_mod = mt8186_mutex_mod,
	.mutex_sof = mt8186_mutex_sof,
	.mutex_mod_reg = MT8183_MUTEX0_MOD0,
	.mutex_sof_reg = MT8183_MUTEX0_SOF0,
};

static const struct mtk_mutex_data mt8186_mdp_mutex_driver_data = {
  	.mutex_mod_reg = MT8183_MUTEX0_MOD0,
  	.mutex_sof_reg = MT8183_MUTEX0_SOF0,
	.mutex_table_mod = mt8186_mdp_mutex_table_mod,
};

P.S.: Notice that mt8186_mdp_mutex_driver_data instead of
       mt8186_mutex_mdp_driver_data was chosen on purpose:
       like that, we're referencing to real block names.

You don't need this entry, as mediatek,mt8186-disp-mutex already uses the same
driver data as this one.

Please drop that.

Everything else looks good.

We would need clarification if the HW block for MDP3 mutex is different from the 
one used for the disp mutex. It does not seem so. In this case we can just add a
