[PATCH v4 0/6] add Amlogic A1 clock controller driver

[PATCH v4 0/6] add Amlogic A1 clock controller driver

[Jian Hu]

add support for Amlogic A1 clock driver, the clock includes 
three parts: peripheral clocks, pll clocks, CPU clocks.
sys pll and CPU clocks will be sent in next patch.

Changes since v3 at [3]:
-fix reparenting orphan failed, it depends on jerome's patch [4]
-fix changelist in v3 about reparenting orphan
-remove the dts patch 

Changes since v2 at [2]:
-add probe function for A1
-seperate the clock driver into two patch
-change some clock flags and ops
-add support for a1 PLL ops
-add A1 clock node
-fix reparenting orphan clock failed, registering xtal_fixpll
 and xtal_hifipll after the provider registration, it is not
 a best way.

Changes since v1 at [1]:
-place A1 config alphabetically
-add actual reason for RO ops, CLK_IS_CRITICAL, CLK_IGNORE_UNUSED
-separate the driver into two driver: peripheral and pll driver
-delete CLK_IGNORE_UNUSED flag for pwm b/c/d/e/f clock, dsp clock
-delete the change in Kconfig.platforms, address to Kevin alone
-remove the useless comments
-modify the meson pll driver to support A1 PLLs

[PATCH v4 2/6] clk: meson: add support for A1 PLL clock ops

[Jian Hu]

The A1 PLL design is different with previous SoCs. The PLL
internal analog modules Power-on sequence is different
with previous, and thus requires a strict register sequence to
enable the PLL.

[PATCH v4 3/6] clk: meson: eeclk: refactor eeclk common driver to support A1

[Jian Hu]

Introduce a common probe function for A1 series, the way to get
regmap is different between A1 series and the previous series.
The register region is only for one clock driver, the function of
meson_eeclkc_probe is not fit for A1, So it is necessary to
introduce a new function.

[PATCH v4 4/6] clk: meson: a1: add support for Amlogic A1 PLL clock driver

[Jian Hu]

The Amlogic A1 clock includes three drivers:
pll clocks, peripheral clocks, CPU clocks.
sys pll and CPU clocks will be sent in next patch.

Unlike the previous series, there is no EE/AO domain
in A1 CLK controllers.

The code does something more, not completly different. This comment is
not aligned with what the code does

Here you enable the PLL and self adaptation module then reset the PLL.
However:
#1 when you enter this function, the PLL should already by in reset
and disabled
#2 the code after that will reset the PLL again

So if what you submited works, inserting the following should accomplish
the same thing:

In any case, nothing should be done on the clock before this check
otherwise you might just break the clock

Re: [PATCH v4 3/6] clk: meson: eeclk: refactor eeclk common driver to support A1

Please drop this patch

#1 you are patching the EE driver for something that is no longer an EE
 driver
#2 Let's get the basics right, you can move (re)factoring afterward

Your probe function is simple enough. Just properly write it in each
driver for now.

From the comment, it looks like this clock should be critical, not ignored

From here, I think you replace the comment with "Refer to a1_fclk_div2"
to avoid pasting the same lines over and over again. Same for the other
clocks below.

#1 It weird that both sys_a and sys_b are critical, Only the leaf needs
 to be critical which, AFAICT, is a1_sys_clk.

#2 Like on the other controller: What the clock is needed for needs is
 needed for for each critical clock, but the explanation below needs to
 appear only once and can be refered to afterward.

These kind of comment just repeating the name of the clock that is
written just below are useless.

Comments should provide useful information to understand the code or the

I'm not sure this works, compatible shouldn't contain a list.

You can write this like:
compatible:
  const: amlogic,a1-pll-clkc

This is redundant, it will be added automatically by the tools ...

... When you have a list of items :)

For A1 PLLs, There is no reset bit, It will not reset the PLL.
And in V2, you mentioned PARM 'rst' can be used for one toggling, And 
'rst' is used for BIT(6) in CTRL2.

Quote V2 the HIFI PLL init_regs definition：


+static const struct reg_sequence a1_hifi_init_regs[] = {
+	{ .reg = ANACTRL_HIFIPLL_CTRL1, .def = 0x01800000 },
+	{ .reg = ANACTRL_HIFIPLL_CTRL2, .def = 0x00001100 },
+	{ .reg = ANACTRL_HIFIPLL_CTRL3, .def = 0x100a1100 },
+	{ .reg = ANACTRL_HIFIPLL_CTRL4, .def = 0x00302000 },
+	{ .reg = ANACTRL_HIFIPLL_CTRL0, .def = 0x01f18440 },
+	{ .reg = ANACTRL_HIFIPLL_CTRL0, .def = 0x11f18440, .delay_us = 10 },
+	{ .reg = ANACTRL_HIFIPLL_CTRL0, .def = 0x15f18440, .delay_us = 40 },
+	{ .reg = ANACTRL_HIFIPLL_CTRL2, .def = 0x00001140 },
+	{ .reg = ANACTRL_HIFIPLL_CTRL2, .def = 0x00001100 },
+};

So maybe another new PARM should be defined to avoid the ambiguity.
What do you think about it?

oh my ! What is it then ? Why do you need to toggle it ? What does is do ?

This is not the point of my comment Jian !

I'm assuming here that you have tested your v4 before sending and that
it work (hopefully)

The fact is that with this code, when disabled the bit behind rst
(whatever it is) is set. So when you get to enable the bit is already set.
The code you sent does the same as the snip I gave you in the reply.

Now, if your PLL is THAT different, maybe it would be best if you could
clearly explain how it works, what bit should be set and why. Then we
will be able to figure out how the driver has to be restructured.

Quote your comment in V2:
-
 From your comment, I understand that some child are critical, not this
particular (or at least, not directly). So this can be removed AFAICT

You should even need CLK_IGNORE_UNUSED for this one since the clock will
already be enabled before the late_init() kicks in
-

You said it should be CLK_IGNORE_UNUSED here.
So I am confused about it.

OK, I will remove the flag CLK_IS_CRITICAL for a1_sys_a and a1_sys_b.
And add it for a1_sys_clk.

I refered to 
Documentation/devicetree/bindings/clock/allwinner,sun4i-a10-ccu.yaml.

I have used 'dt-doc-validate' tools to check, it will report something 
wrong below.

properties:compatible: [{'enum': ['amlogic,a1-pll-clkc']}] is not of 
type 'object', 'boolean'

Refer to
https://github.com/robherring/dt-schema/blob/master/example-schema.yaml

I will change it like this:

properties:
   compatible:
     oneOf:
       - enum:
          - amlogic,a1-pll-clkc

And It has been passed by 'dt-doc-validate' tools.

Is it right?

If I remove the minItems, it will pass by dt-doc-validate.

Would please tell how to use dt-schema to generate automatically it?

The PLL enable flow:
      step1: enable the PLL
      step2: enable the self adaptation module
      step3: reset the lock detect module, let the lock detect module 
            work，And then the PLL will work.

Toggle the bit 6 in CTRL2 can reset the lock detect module.

Yes, it works wells. I have tested the drivers before sending every

You can simply do

properties:
  compatible:
    const: amlogic,a1-pll-clkc

You don't have to do anything, it's just done at the tools runtime.

#1  I intend to introduce a new PARM 'l_detect', and the 
meson_clk_pll_enable is blow. Please help to review it.

static int meson_clk_pll_enable(struct clk_hw *hw)
{
         struct clk_regmap *clk = to_clk_regmap(hw);
         struct meson_clk_pll_data *pll = meson_clk_pll_data(clk);

         /* do nothing if the PLL is already enabled */
         if (clk_hw_is_enabled(hw))
                 return 0;
         /*
          * Compared with the previous SoCs, self-adaption module current
          * is newly added, keep the new power-on sequence to enable the
          * PLL.
          */
         if (MESON_PARM_APPLICABLE(&pll->current_en)) {
                 /* Enable the pll */
                 meson_parm_write(clk->map, &pll->en, 1);
                 udelay(10);
                 /* Enable the pll self-adaption module current */
                 meson_parm_write(clk->map, &pll->current_en, 1);
                 udelay(40);
                 /* Enable lock detect module */
                 meson_parm_write(clk->map, &pll->l_detect, 1);
                 meson_parm_write(clk->map, &pll->l_detect, 0);
                 goto out;
         }

         /* Make sure the pll is in reset */
         meson_parm_write(clk->map, &pll->rst, 1);

         /* Enable the pll */
         meson_parm_write(clk->map, &pll->en, 1);

         /* Take the pll out reset */
         meson_parm_write(clk->map, &pll->rst, 0);

out:
         if (meson_clk_pll_wait_lock(hw))
                 return -EIO;

         return 0;
}


#2  Add check for PARM 'rst' when
writing to it, the same with frac.

if (MESON_PARM_APPLICABLE(&pll->rst))
    meson_parm_write(clk->map, &pll->rst, 1);


And I have tested it for it, The periphs and hifi pll works well.

Or any good idea about it?
