[U-Boot] [PATCH V3 0/3] Introduce Samsung's new board Trats2

[Piotr Wilczek]

This patchset add support for a new Samsung board Trats2.
Multi I2C file is update to support more buses.
Battery support is added for Trats2.

This patchset depends on:
http://patchwork.ozlabs.org/patch/246101/
http://patchwork.ozlabs.org/patch/246100/
http://patchwork.ozlabs.org/patch/245311/
http://patchwork.ozlabs.org/patch/245307/
http://patchwork.ozlabs.org/patch/245306/

Changes in v3:
- add Maintainer entry
- changed T-flash detect pin to GPX3[3]
- removed MMC_ASYNC
- use only software i2c

Changes in v2:
- removed lcd callback in panel_info
- changed i2c from hardware to software
- use max77693 multifunction pmic

[Jaehoon Chung]

Hi Piotr,

I tested your patches on trats2 board.
I found the below log message..If i missed some patch, let me know.

Board PMIC init
Can't find PMIC:MAX77686_PMIC

What's this log?

Best Regards,
Jaehoon Chung

[U-Boot] [PATCH V4 0/3] Introduce Samsung's new board Trats2

[Piotr Wilczek]

This patchset add support for a new Samsung board Trats2.
Multi i2c file is updated for third soft I2C adapter for Trats2 board
Battery support is added for Trats2.

This patchset depends on:
http://patchwork.ozlabs.org/patch/254056/
http://patchwork.ozlabs.org/patch/245307/

Changes in v4:
- rebased on the latest tree
- modified default boot envs

Changes in v3:
- add Maintainer entry
- changed T-flash detect pin to GPX3[3]
- removed MMC_ASYNC
- use only software i2c

Changes in v2:
- removed lcd callback in panel_info
- changed i2c from hardware to software
- use max77693 multifunction pmic

bat_trats2.c is almost same with bat_trat.c
I think, it can be reuse bat_trat.c
Do you have special reason to add new file?

If several boards would use that file, any change to it will affect all
these boards. Also why it should be named 'bat_trats' then?

Other reason is that I don't want to block command line while charging
battery as in 'bat_trats'.

Anyway it's not that important. I will modify it the way you prefer.

Is this reason good enough to add new file or should I post a new version of
this patch?

OK. I understood what you said.

But, I don't understand why this file (or directory - battery) is needed.
It is not a driver,
it just settings for specific board.
If so, why don't you move to board file instead?
Do we need to make new files for every boards?

Lukasz,
how you think?

In the pmic framework the battery is treated in the same way as MUIC,
PMIC, FG. This is the reason for separate directory.

I would like to avoid code duplication.


> Do we need to make new files for every boards?

The problem here is with the way we are handling charging. Trats uses
the "busy loop" approach.
In the TRATS2 the busy loop is omitted, and only charging is enabled.

Those are two different approaches for handling charging (this may also
depend on PMIC capabilities).


> 
> Lukasz,
> how you think?

For the PMIC itself - it needs to be rewritten to be prepared for multi
board support for u-boot. It doesn't support it now (as Tom pointed
out recently).

Also - as shown with PMIC batteries - different charging "profiles" are
needed.

The bat_trats.c, bat_trats2.c [*] would be renamed to bat_profile1.c and
bat_profile2.c. Also some common code from [*] would be extracted.

Now it seems, that acceptance of Trats2 board depends on the
shortcoming in the PMIC framework.

My proposition - accept the Trats2 code (since it works and is tested).

The battery code is going to be cleaned up when we finish and post PMIC
framework rework.

I will post request for PMIC v3 requirements soon.

[U-Boot] [PATCH V5 0/3] Introduce Samsung's new board Trats2

[Piotr Wilczek]

This patchset add support for a new Samsung board Trats2.
Multi i2c file is updated for third soft I2C adapter for Trats2 board
Battery support is added for Trats2.

This patchset depends on:
http://patchwork.ozlabs.org/patch/245307/

Changes in v5:
- updated Maintainer entry
- removed direct access to registers
- in board_mmc_init error is return only if both mmc card init fails

Changes in v4:
- rebased on the latest tree
- modified default boot envs

Changes in v3:
- add Maintainer entry
- changed T-flash detect pin to GPX3[3]
- removed MMC_ASYNC
- use only software i2c

Changes in v2:
- removed lcd callback in panel_info
- changed i2c from hardware to software
- use max77693 multifunction pmic

[U-Boot] [PATCH V6 0/3] Introduce Samsung's new board Trats2

[Piotr Wilczek]

This patchset add support for a new Samsung board Trats2.
Multi i2c file is updated for third soft I2C adapter for Trats2 board
Battery support is added for Trats2.

This patchset depends on:
http://patchwork.ozlabs.org/patch/245307/

Changes in v6:
- fixed build issue for other board.

Changes in v5:
- updated Maintainer entry
- removed direct access to registers
- in board_mmc_init error is return only if both mmc card init fails

Changes in v4:
- rebased on the latest tree
- modified default boot envs

Changes in v3:
- add Maintainer entry
- changed T-flash detect pin to GPX3[3]
- removed MMC_ASYNC
- use only software i2c

Changes in v2:
- removed lcd callback in panel_info
- changed i2c from hardware to software
- use max77693 multifunction pmic

Piotr Wilczek (3):
  power:battery: add battery support for Trats2 board
  samsung:common:i2c: add definions for third soft I2C adapter for
    Trats2 board
