Hi everyone,

This is v3 of my A83T CCU series. This is for 4.13.

Changes since v2:

  - Dropped patches "clk: Provide option to query hardware for clk phase"
    and "clk: sunxi-ng: Add class of phase clocks supporting MMC new timing
    modes".
    
  - Dropped support for MMC new timing mode. This will be added later with
    MMC support. The goal for this series is to get clk support for the A83t
    in. This is long overdue.

  - Explicitly include ccu_mux.h and select SUNXI_CCU_MUX

Changes since v1:

  - Dropped two patches that were merged

  - Added clk core flag to disable caching of clock phases

  - Added support for multiple variable pre-dividers

  - Merged "pll-periph-ahb1" pre-divider clock into "ahb1" clock
    with multiple variable pre-dividers

  - Introduced new class of phase clocks that return -ENOTSUPP
    when the clock is in new timing mode

  - Force mmc2 clock to new timing mode

  - Added back mmc2 output and sample clocks

  - Fixed bit ops for forcing audio PLL configuration

  - Added requirement for "losc" clock in device tree binding

  - Stripped leading 0 in device node name

  - Updated subject prefixes for various patches

Patch 1 adds a compatible string for the A83T CCU to the sunxi-ccu
bindings.

Patch 2 adds support for multiple variable pre-dividers to the sunxi-ng
mux class.

Patch 3 adds the driver for the A83T CCU.

Patch 4 adds the CCU device nodes, and fixes up any existing clock
phandles in the dtsi, without using the macros.

Patch 5 sets the clock accuracy for the main oscillator.

Patch 6 is for the next -rc2, switch the clock indices from raw numbers
to macros we introduced with the driver. This will be updated if more
peripherals are introduced in the same cycle.

Let me know what you think.

Cover letter excerpt from v1:

This is yet another series that adds support for the A83T CCU.
The A83T CCU has a mix of new styled (like the A80) clocks at
old (like A3x) offsets. Some differences include:

  - D1/D2 style PLL clocks
  - divisible audio module clocks
  - new timing mode for mmc2 module clock

The A83T clock control unit is a hybrid of some new style clock designs
from the A80, and old style layout from the other Allwinner SoCs.

Like the A80, the SoC does not have a low speed 32.768 kHz oscillator.
Unlike the A80, there is no clock input either. The only low speed clock
available is the internal oscillator which runs at around 16 MHz,
divided by 512, yielding a low speed clock around 31.250 kHz.

On the A83T, the AHB1 clock has a shared pre-divider on the two
PLL-PERIPH clock parents. To support such instances of shared
pre-dividers, this patch extends the mux clock type to support
multiple variable pre-dividers.

As the pre-dividers are only used to calculate the rate, but
do not participate in the factorization process, this is fairly
straightforward.

On the A83T, the AHB1 clock has a shared pre-divider on the two
PLL-PERIPH clock parents. To support such instances of shared
pre-dividers, this patch extends the mux clock type to support
multiple variable pre-dividers.

As the pre-dividers are only used to calculate the rate, but
do not participate in the factorization process, this is fairly
straightforward.

* [PATCH v3 2/6] clk: sunxi-ng: Support multiple variable pre-dividers
@ 2017-05-18  3:58   ` Chen-Yu Tsai
  0 siblings, 0 replies; 27+ messages in thread
From: Chen-Yu Tsai @ 2017-05-18  3:58 UTC (permalink / raw)
  To: linux-arm-kernel

On the A83T, the AHB1 clock has a shared pre-divider on the two
PLL-PERIPH clock parents. To support such instances of shared
pre-dividers, this patch extends the mux clock type to support
multiple variable pre-dividers.

As the pre-dividers are only used to calculate the rate, but
do not participate in the factorization process, this is fairly
straightforward.

* [PATCH v3 3/6] clk: sunxi-ng: Add driver for A83T CCU
@ 2017-05-18  3:58   ` Chen-Yu Tsai

From: Chen-Yu Tsai @ 2017-05-18  3:58 UTC (permalink / raw)
  To: Maxime Ripard, Michael Turquette, Stephen Boyd, Rob Herring,

  Cc: Chen-Yu Tsai, devicetree, linux-arm-kernel, linux-clk,
	linux-kernel, linux-sunxi

The A83T clock control unit is a hybrid of some new style clock designs
from the A80, and old style layout from the other Allwinner SoCs.

Like the A80, the SoC does not have a low speed 32.768 kHz oscillator.
Unlike the A80, there is no clock input either. The only low speed clock
available is the internal oscillator which runs at around 16 MHz,
divided by 512, yielding a low speed clock around 31.250 kHz.

Also, the MMC2 module clock supports switching to a "new timing" mode.
This mode divides the clock output by half, and disables the CCU based
clock delays. The MMC controller must be configure to the same mode,
and then use its internal clock delays.

This driver does not support runtime switching of the timing modes.
Instead, the new timing mode is enforced at probe time. Consumers can
check which mode is active by trying to get the current phase delay
of the MMC2 phase clocks, which will return -ENOTSUPP if the new
timing mode is active.

* [PATCH v3 3/6] clk: sunxi-ng: Add driver for A83T CCU

The A83T clock control unit is a hybrid of some new style clock designs
from the A80, and old style layout from the other Allwinner SoCs.

Like the A80, the SoC does not have a low speed 32.768 kHz oscillator.
Unlike the A80, there is no clock input either. The only low speed clock
available is the internal oscillator which runs at around 16 MHz,
divided by 512, yielding a low speed clock around 31.250 kHz.

Also, the MMC2 module clock supports switching to a "new timing" mode.
This mode divides the clock output by half, and disables the CCU based
clock delays. The MMC controller must be configure to the same mode,
and then use its internal clock delays.

This driver does not support runtime switching of the timing modes.
Instead, the new timing mode is enforced at probe time. Consumers can
check which mode is active by trying to get the current phase delay
of the MMC2 phase clocks, which will return -ENOTSUPP if the new
timing mode is active.

* [PATCH v3 3/6] clk: sunxi-ng: Add driver for A83T CCU
@ 2017-05-18  3:58   ` Chen-Yu Tsai
  0 siblings, 0 replies; 27+ messages in thread
From: Chen-Yu Tsai @ 2017-05-18  3:58 UTC (permalink / raw)
  To: linux-arm-kernel

The A83T clock control unit is a hybrid of some new style clock designs
from the A80, and old style layout from the other Allwinner SoCs.

Like the A80, the SoC does not have a low speed 32.768 kHz oscillator.
Unlike the A80, there is no clock input either. The only low speed clock
available is the internal oscillator which runs at around 16 MHz,
divided by 512, yielding a low speed clock around 31.250 kHz.

Also, the MMC2 module clock supports switching to a "new timing" mode.
This mode divides the clock output by half, and disables the CCU based
clock delays. The MMC controller must be configure to the same mode,
and then use its internal clock delays.

This driver does not support runtime switching of the timing modes.
Instead, the new timing mode is enforced at probe time. Consumers can
check which mode is active by trying to get the current phase delay
of the MMC2 phase clocks, which will return -ENOTSUPP if the new
timing mode is active.

  Cc: Chen-Yu Tsai, devicetree, linux-arm-kernel, linux-clk,

Now that we have support for the A83T CCU, add a device node for it,
and replace any existing placeholder clock phandles with the correct
ones.

The datasheets for Allwinner SoCs set strict requirements on the
stability of the external crystal oscillators. Add the accuracy
for the main 24MHz oscillator to the device tree.

Now that the CCU device tree binding headers have been merged, we can
use the properly named macros in the device tree, instead of raw
numbers.

I'm sorry to be a pain for this, but we're in the exact same situation
for the A83T than the A33 or the H3. There's no reason we'd do
something different with the MMC clocks only on the A83T.

What I'd like to happen is:
  1) Get the A83T ccu driver in, without *any* of the new mode
     handling.
  2) Work on the new mode for the A33, A83T and H3 (and the other I
     might have forgotten).

This issue really isn't A83 specific, there's no reason to come up
with A83 specific code.

So to recap, you want mmc2_clk without the new pre-dividers here.
Then we add them for _all_ SoCs that have the old/new mode switch
at the same time. Is that correct?

This really isn't A83T specific code. It's just one way to handle
the extra divider for the new timing mode. Obviously we will add the
functions to query and set the timing mode bit, but that will be
generic. If you want all code related to the new mode in one patch,
then I understand.

So to recap, you want mmc2_clk without the new pre-dividers here.
Then we add them for _all_ SoCs that have the old/new mode switch
at the same time. Is that correct?

This really isn't A83T specific code. It's just one way to handle
the extra divider for the new timing mode. Obviously we will add the
functions to query and set the timing mode bit, but that will be
generic. If you want all code related to the new mode in one patch,
then I understand.
