Hi everyone,
Here is the migration for the A23 and A33 clocks to the sunxi-ng
framework.
It has been tested on SinA33 board, and I made sure that everything
was reported at the exact same rate, that the MMC was still working in
DDR, etc.
This has also been tested to implement the DRM driver, so I'm
confident things will work just fine.
Let me know what you think,
Maxime
Changes from v2:
- Added the msgbox reset and spinlock clocks
- Added some doc for the max value for the dividers
- Removed whitespace error
Changes from v1:
- Allowed to set a maximum on the dividers, and used that on the CPU
clocks
- Renamed the CE (crypto engine) clocks to SS (security system) to
stick to what's being used in the datasheet
- Added a TODO to mention that we don't really know whose parents
are linked to the USB clocks.
Maxime Ripard (8):

The internal _ccu_div structure is meant to be embedded into other
structures to combine the various dividers and to form the clock classes
support.
Start to document those structures by using kerneldoc.

Some dividers might have a maximum value that is lower than the width of
the register.
Add a field to _ccu_div to handle those case properly. If the field is set
to 0, the code will assume that the maximum value is the maximum one that
can be used with the field register width.
Otherwise, we'll use whatever value has been set.

Some dividers might have a maximum value that is lower than the width of
the register.
Add a field to _ccu_div to handle those case properly. If the field is set
to 0, the code will assume that the maximum value is the maximum one that
can be used with the field register width.
Otherwise, we'll use whatever value has been set.

* [PATCH v3 6/8] clk: sunxi-ng: Add A33 CCU support

This commit introduces the clocks found in the Allwinner A33 CCU.
Since this SoC is very similar to the A23, and we share a significant share
of the DTSI, the clock IDs that are going to be used will also be shared
with the A23, hence the name of the various header files.

* [PATCH v3 6/8] clk: sunxi-ng: Add A33 CCU support
@ 2016-09-08 9:48 ` Maxime Ripard
0 siblings, 0 replies; 29+ messages in thread
From: Maxime Ripard @ 2016-09-08 9:48 UTC (permalink / raw)
To: linux-arm-kernel
This commit introduces the clocks found in the Allwinner A33 CCU.
Since this SoC is very similar to the A23, and we share a significant share
of the DTSI, the clock IDs that are going to be used will also be shared
with the A23, hence the name of the various header files.

* [PATCH v3 7/8] clk: sunxi-ng: Add A23 CCU

Add support for the clock unit found in the A23. Due to the similarities
with the A33, it also shares its clock IDs to allow sharing the DTSI.

* [PATCH v3 7/8] clk: sunxi-ng: Add A23 CCU
@ 2016-09-08 9:48 ` Maxime Ripard
0 siblings, 0 replies; 29+ messages in thread
From: Maxime Ripard @ 2016-09-08 9:48 UTC (permalink / raw)
To: linux-arm-kernel
Add support for the clock unit found in the A23. Due to the similarities
with the A33, it also shares its clock IDs to allow sharing the DTSI.

* [PATCH v3 8/8] ARM: sun8i: Convert the A23 and A33 to the CCU

Now that we have support for the CCU driver in sunxi-ng, convert the A23
and A33 DTs to that driver.

* [PATCH v3 8/8] ARM: sun8i: Convert the A23 and A33 to the CCU
@ 2016-09-08 9:48 ` Maxime Ripard

From: Maxime Ripard @ 2016-09-08 9:48 UTC (permalink / raw)
To: linux-arm-kernel
Now that we have support for the CCU driver in sunxi-ng, convert the A23
and A33 DTs to that driver.
