On both MT8183 & MT6765, there add "set/clr" register for
each clkmux setting, and one update register to trigger value change.
It is designed to prevent read-modify-write racing issue.
The sw design need to add a new API to handle this hw change with
a new mtk_clk_mux/mtk_mux struct in new file "clk-mux.c", "clk-mux.h".

[PATCH v2 01/11] clk: mediatek: add new clkmux register API

[Weiyi Lu]

From: Owen Chen <owen.chen@mediatek.com>

On both MT8183 & MT6765, there add "set/clr" register for
each clkmux setting, and one update register to trigger value change.
It is designed to prevent read-modify-write racing issue.
The sw design need to add a new API to handle this hw change with
a new mtk_clk_mux/mtk_mux struct in new file "clk-mux.c", "clk-mux.h".

[PATCH v2 01/11] clk: mediatek: add new clkmux register API

[Weiyi Lu]

From: Owen Chen <owen.chen@mediatek.com>

On both MT8183 & MT6765, there add "set/clr" register for
each clkmux setting, and one update register to trigger value change.
It is designed to prevent read-modify-write racing issue.
The sw design need to add a new API to handle this hw change with
a new mtk_clk_mux/mtk_mux struct in new file "clk-mux.c", "clk-mux.h".

nit: No blank line here. Or at least be consistent with what
mtk_clk_mux_disable_setclr does below.

Also, put everything on one line:
u32 val = BIT(mux->gate_shift);
(or, again, at least be self-consistent)

nit: No blank line here. Or at least be consistent with what

Also, put everything on one line:
u32 val = BIT(mux->gate_shift);
(or, again, at least be self-consistent)

prefer to
return regmap_update_bits(mux->regmap, mux->mux_ofs, mask, ~mask);
just to align with mtk_clk_mux_disable

prefer to
return regmap_write(mux->regmap, mux->mux_clr_ofs, BIT(mux->gate_shift));
and drop u32 val declaration

perfer to
regmap_write(mux->regmap, mux->mux_set_ofs, BIT(mux->gate_shift));
and drop u32 val

an u32 to u8 happens here

regmap_update_bits(mux->regmap, mux->mux_ofs, mask, index << mux->mux_shift);
appears to be sufficient. regmap_update_bits would check whether the
register write is necessary.

[PATCH v2 01/11] clk: mediatek: add new clkmux register API

[Sean Wang]

 >
> From: Owen Chen <owen.chen@mediatek.com>
>
> On both MT8183 & MT6765, there add "set/clr" register for
> each clkmux setting, and one update register to trigger value change.
> It is designed to prevent read-modify-write racing issue.
> The sw design need to add a new API to handle this hw change with
> a new mtk_clk_mux/mtk_mux struct in new file "clk-mux.c", "clk-mux.h".

prefer to
return regmap_update_bits(mux->regmap, mux->mux_ofs, mask, ~mask);
just to align with mtk_clk_mux_disable

prefer to
return regmap_write(mux->regmap, mux->mux_clr_ofs, BIT(mux->gate_shift));
and drop u32 val declaration

perfer to
regmap_write(mux->regmap, mux->mux_set_ofs, BIT(mux->gate_shift));
and drop u32 val

an u32 to u8 happens here

regmap_update_bits(mux->regmap, mux->mux_ofs, mask, index << mux->mux_shift);
appears to be sufficient. regmap_update_bits would check whether the
register write is necessary.

[PATCH v2 02/11] clk: mediatek: add new member to mtk_pll_data

[Weiyi Lu]

From: Owen Chen <owen.chen@mediatek.com>

1. pcwibits: The integer bits of pcw for plls is extend to 8 bits,
   add a variable to indicate this change and
   backward-compatible.
2. fmin: The pll freqency lower-bound is vary from 1GMhz to
   1.5Ghz, add a variable to indicate platform-dependent.

[PATCH v2 02/11] clk: mediatek: add new member to mtk_pll_data

[Weiyi Lu]

From: Owen Chen <owen.chen@mediatek.com>

1. pcwibits: The integer bits of pcw for plls is extend to 8 bits,
   add a variable to indicate this change and
   backward-compatible.
2. fmin: The pll freqency lower-bound is vary from 1GMhz to
   1.5Ghz, add a variable to indicate platform-dependent.

The patch title seems much general. It should be more specific to
reflect the content,
such as add configurable parameters pcwibits and fmin to mtk_pll.

[PATCH v2 03/11] clk: mediatek: Disable tuner_en before change PLL rate

[Weiyi Lu]

From: Owen Chen <owen.chen@mediatek.com>

PLLs with tuner_en bit, such as APLL1, need to disable
tuner_en before apply new frequency settings, or the new frequency
settings (pcw) will not be applied.
The tuner_en bit will be disabled during changing PLL rate
and be restored after new settings applied.

[PATCH v2 03/11] clk: mediatek: Disable tuner_en before change PLL rate

[Weiyi Lu]

From: Owen Chen <owen.chen@mediatek.com>

PLLs with tuner_en bit, such as APLL1, need to disable
tuner_en before apply new frequency settings, or the new frequency
settings (pcw) will not be applied.
The tuner_en bit will be disabled during changing PLL rate
and be restored after new settings applied.

It looks like a bug fix. If so, you should add a fixes tag and even cc
stable tree

Below, you have:
con1 |= CON1_PCW_CHG;

Presumably PCW_CHG is on BIT(31) of CON1(?), so I think this is a good
change. Maybe this needs to be a separate patch, though?

change. Maybe this needs to be a separate patch, though?

Sure, for me it's not easily understood why the change is necessary
from the description. If it's really another fixup, it should be moved
to a separate patch or add more explanations about that in the same
patch.

[PATCH v2 04/11] soc: mediatek: add new flow for mtcmos power.

[Weiyi Lu]

From: Owen Chen <owen.chen@mediatek.com>

Both MT8183 & MT6765 add more bus protect node than previous project,
therefore we add two more register for setup bus protect, which reside
at INFRA_CFG & SMI_COMMON.

With the following change
1. bus protect need not only infracfg but smi_common registers involved
   to setup. Therefore we add a set/clr APIs with more customize arguments.

The second change is that we also add subsys CG control flow before/after
the bus protect/sram control, due to bus protect need SMI bus relative CGs
enable to feed-back its ack, and some master's sram control need CG enable
to on/off its resource sequentially.

With the following change
1. turn on subsys CG before sram pwron and release bus protect.
2. turn off subsys CG after the process of set bus protect/receive
   ack/disable sram.

The last change is for some power domains like vpu_core on MT8183 whose
sram need to do clock and internal isolation while power on/off sram.
We add a flag "sram_iso_ctrl" in scp_domain_data to judge if we need to
do the extra sram isolation control or not.

[PATCH v2 04/11] soc: mediatek: add new flow for mtcmos power.

[Weiyi Lu]

From: Owen Chen <owen.chen@mediatek.com>

Both MT8183 & MT6765 add more bus protect node than previous project,
therefore we add two more register for setup bus protect, which reside
at INFRA_CFG & SMI_COMMON.

With the following change
1. bus protect need not only infracfg but smi_common registers involved
   to setup. Therefore we add a set/clr APIs with more customize arguments.

The second change is that we also add subsys CG control flow before/after
the bus protect/sram control, due to bus protect need SMI bus relative CGs
enable to feed-back its ack, and some master's sram control need CG enable
to on/off its resource sequentially.

With the following change
1. turn on subsys CG before sram pwron and release bus protect.
2. turn off subsys CG after the process of set bus protect/receive
   ack/disable sram.

The last change is for some power domains like vpu_core on MT8183 whose
sram need to do clock and internal isolation while power on/off sram.
We add a flag "sram_iso_ctrl" in scp_domain_data to judge if we need to
do the extra sram isolation control or not.

From: Owen Chen <owen.chen@mediatek.com>

Both MT8183 & MT6765 add more bus protect node than previous project,
therefore we add two more register for setup bus protect, which reside
at INFRA_CFG & SMI_COMMON.

With the following change
1. bus protect need not only infracfg but smi_common registers involved
   to setup. Therefore we add a set/clr APIs with more customize arguments.

The second change is that we also add subsys CG control flow before/after
the bus protect/sram control, due to bus protect need SMI bus relative CGs
enable to feed-back its ack, and some master's sram control need CG enable
to on/off its resource sequentially.

With the following change
1. turn on subsys CG before sram pwron and release bus protect.
2. turn off subsys CG after the process of set bus protect/receive
   ack/disable sram.

The last change is for some power domains like vpu_core on MT8183 whose
sram need to do clock and internal isolation while power on/off sram.
We add a flag "sram_iso_ctrl" in scp_domain_data to judge if we need to
do the extra sram isolation control or not.

This function is so simple that I'm not sure why it was added.
Wouldn't be generally simpler to just call
regulator_enable/disable(scpd->supply) in the code below? (as was done
before this refactoring)

I don't find this pattern particularly nice:
int func_onoff(bool on) {
  if (on) enable();
  else disable();
}

Especially give that you always call func_onoff with either hard-coded
true or false parameter.

I think 2 sets of functions (func_enable and func_disable) is probably
better in this case.

This one is a little more borderline, but IMHO enable/disable would
still be more readable.

I'd also do an enable/disable pair of function, that could look very simple:

...
{
  ...
  if (scpd->data->bus_prot_mask)
     return mtk_infracfg_set_bus_protection(scp->infracfg,
                                       scpd->data->bus_prot_mask,
                                       scp->bus_prot_reg_update);
  else
     return mtk_scpsys_ext_set_bus_protection(
                                       scpd->data->bp_table,

Shouldn't this just be clk_name[prefix_len] == '-' ? At least that's
how it seems to work right now ("mm" matches "mm-0", "mm-1", etc.)

Also, I'm wondering if this prefix matching approach is best, but I'll
let other people comment.

Please use brackets {} here, makes the code clearer (even though

This function is so simple that I'm not sure why it was added.
Wouldn't be generally simpler to just call
regulator_enable/disable(scpd->supply) in the code below? (as was done
before this refactoring)

I don't find this pattern particularly nice:
int func_onoff(bool on) {
  if (on) enable();
  else disable();
}

Especially give that you always call func_onoff with either hard-coded
true or false parameter.

I think 2 sets of functions (func_enable and func_disable) is probably
better in this case.

This one is a little more borderline, but IMHO enable/disable would
still be more readable.

I'd also do an enable/disable pair of function, that could look very simple:

...
{
  ...
  if (scpd->data->bus_prot_mask)
     return mtk_infracfg_set_bus_protection(scp->infracfg,
                                       scpd->data->bus_prot_mask,
                                       scp->bus_prot_reg_update);
  else
     return mtk_scpsys_ext_set_bus_protection(
                                       scpd->data->bp_table,
                                       scp->infracfg,
                                       scp->smi_common);
  return 0;
}

Shouldn't this just be clk_name[prefix_len] == '-' ? At least that's
how it seems to work right now ("mm" matches "mm-0", "mm-1", etc.)

Also, I'm wondering if this prefix matching approach is best, but I'll
let other people comment.

[PATCH v2 07/11] clk: mediatek: Add flags support for mtk_gate data

[Weiyi Lu]

On some Mediatek platforms, there are critical clocks of
clock gate type.
To register clock gate with flags CLK_IS_CRITICAL,
we need to add the flags field in mtk_gate data and register APIs.

[PATCH v2 07/11] clk: mediatek: Add flags support for mtk_gate data

[Weiyi Lu]

On some Mediatek platforms, there are critical clocks of
clock gate type.
To register clock gate with flags CLK_IS_CRITICAL,
we need to add the flags field in mtk_gate data and register APIs.
