[PATCH 0/4] ARM: sun7i: Convert sun7i SoC to sunxi-ng

[PATCH 0/4] ARM: sun7i: Convert sun7i SoC to sunxi-ng

[Priit Laes]

Hi,

This is serie brings another SoC into the sunxi-ng world.

As mentioned in sun5i conversion, this is pretty much standard
stuff as all the required clocks were already implemented in
the sunxi-ng framework.


Priit Laes (4):
  clk: sunxi-ng: Add clocks and reset indices for sun7i-a20 SoC
  clk: sunxi-ng: Add sun7i-a20 CCU driver
  ARM: sun7i: Convert to CCU
  dt-bindings: List devicetree binding for the CCU of Allwinner A20

 Do you mind dual licence those header under GPL/MIT like the others ?
 We currently dont use those directly in FreeBSD but we should (and
will soon) and we can't if they are only GPL.

 Thanks.

 We use HDMI (not HDMI1) on FreeBSD (see
https://svnweb.freebsd.org/base/head/sys/boot/fdt/dts/arm/sun7i-a20-hdmi.dtsi?revision=308672&view=markup#l71)

 If you could define it in your patch this will be great.

 Do you mind dual licence those header under GPL/MIT like the others ?
 We currently dont use those directly in FreeBSD but we should (and
will soon) and we can't if they are only GPL.

 Thanks.

 We use HDMI (not HDMI1) on FreeBSD (see
https://svnweb.freebsd.org/base/head/sys/boot/fdt/dts/arm/sun7i-a20-hdmi.dtsi?revision=308672&view=markup#l71)

 If you could define it in your patch this will be great.

I don't think we need those TODO's at all, and these comments too. If
the clock name is good enough (and it is), it's redundant.

You're forgetting the post-divider here

Please add all the clocks.

I'm not sure we need those comments either.

Which external clock? It should be modelled anyway. If we have a
dependency on some other clock, it should be in our DT binding, and
listed in the mux there.

Otherwise, the clock framework will not be able to deal with that mux
being already set by the bootloader, and if we need to support that
clock in the future, our binding will be ready for it.

It feels more natural to just have the clocks defined in the same
order than their parents. So periph shouldn't be first

I'm not sure why that last sentence is needed too. A lot of clock
listed there change rate when <some-feature> is enabled.

Is there a reason not to expose these clocks?

I don't think we need those TODO's at all, and these comments too. If
the clock name is good enough (and it is), it's redundant.

You're forgetting the post-divider here

Please add all the clocks.

I'm not sure we need those comments either.

Which external clock? It should be modelled anyway. If we have a
dependency on some other clock, it should be in our DT binding, and
listed in the mux there.

Otherwise, the clock framework will not be able to deal with that mux
being already set by the bootloader, and if we need to support that
clock in the future, our binding will be ready for it.

It feels more natural to just have the clocks defined in the same
order than their parents. So periph shouldn't be first

I'm not sure why that last sentence is needed too. A lot of clock

Is there a reason not to expose these clocks?

Which external clock? It should be modelled anyway. If we have a
dependency on some other clock, it should be in our DT binding, and
listed in the mux there.

Otherwise, the clock framework will not be able to deal with that mux
being already set by the bootloader, and if we need to support that
clock in the future, our binding will be ready for it.

It feels more natural to just have the clocks defined in the same
order than their parents. So periph shouldn't be first

Is there a reason not to expose these clocks?

It's hardcoded to 4 during ccu initialization, similar to what is done
on the other SoCs (A13, A31..).

I'm not really comfortable adding clocks for blocks that currently lack
drivers.

I wish I knew which clock they're talking about..

User manuals (A10/A20) only specify following in the clock register
description:

BIT(24) - CLK_SRC_GATING, default 0x0
Clock Source Select:
0: PLL6 for SATA(100MHz)
1: External Clock

There's no section for SATA (called NC) in A10 manual, and in A20
manual only contains list of SATA/AHCI features.

Ok, will move the periph clock after the video.

It's hardcoded to 4 during ccu initialization, similar to what is done
on the other SoCs (A13, A31..).

I'm not really comfortable adding clocks for blocks that currently lack
drivers.

I wish I knew which clock they're talking about..

User manuals (A10/A20) only specify following in the clock register
description:

BIT(24) - CLK_SRC_GATING, default 0x0
Clock Source Select:
0: PLL6 for SATA(100MHz)
1: External Clock

There's no section for SATA?(called NC) in A10 manual, and in A20
manual only contains list of SATA/AHCI features.

Ok, will move the periph clock after the video.

I exposed them on need to have basis. And basically did one-to-one

I exposed them on need to have basis. And basically did one-to-one
conversion from devicetree.

Right, sorry, I only saw it later. Please move that define you've been
using here, and it will be fine :)

Yet, you did it for quite a significant amount already (VE, NAND,
AC97, DE MP, etc.). Don't get me wrong, this is definitely not a
criticism. One of the point of the switch to sunxi-ng was that we
would get out of the previous situation where every time you wanted to
do something, you needed to add some clocks.

We have some generic code that, if fed the right data, will
(hopefully) just work. So it's pretty safe to add (and this is better
to be consistent, and that's the policy we had for all the other CCU
drivers).

I guess we can still make some pretty good assumptions on what's going
to be needed at some point.

All the mod clocks will be, the bus gates too, the CPU too. All the
internal ones (PLL, AXI, APB, etc) can remain hidden though.

Thanks!

I guess we can still make some pretty good assumptions on what's going
to be needed at some point.

All the mod clocks will be, the bus gates too, the CPU too. All the
internal ones (PLL, AXI, APB, etc) can remain hidden though.

Thanks!

The external clock is probably an optional crystal or oscillator
that can be connected to the SATA-CLKM / SATA-CLKP pins.

The datasheet does not say what the frequency or any other parameters
should be though. And to my knowledge no board uses it.

The external clock is probably an optional crystal or oscillator
that can be connected to the SATA-CLKM / SATA-CLKP pins.

The datasheet does not say what the frequency or any other parameters
should be though. And to my knowledge no board uses it.

Yup, that 's leftover from changes made during initial debugging. Will
fix in v2.

This is how most of the existing drivers handle it (A13, A31, A33) so I
didn't want to do anything fancy.. 
Besides, the code for clock actually configures gate:

static SUNXI_CCU_GATE(hosc_clk, "hosc", "osc24M", 0x050, BIT(0), 0);

[Priit Laes]

Allwinner A20 is now driven by sunxi-ng CCU driver.

Add devicetree binding for it.
