[U-Boot] [PATCH v3 1/6] mx25pdk: Include CONFIG_MX25

[U-Boot] [PATCH v3 1/6] mx25pdk: Include CONFIG_MX25

[Fabio Estevam]

It is necessary to include CONFIG_MX25 as several i.mx drivers handle the SoC
differences based on the this config option.

[U-Boot] [PATCH v3 3/6] pmic_fsl: Introduce FSL_PMIC_I2C_LENGTH

[Fabio Estevam]

Introduce FSL_PMIC_I2C_LENGTH to configure the number of bytes that are used to 
communicate with the PMIC via I2C.

Instead of hardcoding the value, pass the number via a configurable option per
PMIC type.

This will be useful for adding support for PMIC MC34704 from Freescale, which 
uses only one byte in its I2C protocol.

mx25pdk has a Ethernet port that is connected to its internal FEC controller.

In order to power up the Ethernet PHY (DP83640) it is necessary to communicate
with the MC34704 PMIC via I2C.

Make the FEC ethernet port functional

I think this can break boards with MX3 where the MC13783 is used, and
where MC13892 is not set.

At the moment, MC34704 is the one that requires a short lenght. Maybe it
is better to set 3 as default:

#if defined(CONFIG_PMIC_FSL_MC34704)
#define FSL_PMIC_I2C_LENGTH	1
#else
#define FSL_PMIC_I2C_LENGTH	3
#endif

[U-Boot] [PATCH v3 4/6] mic: Add support for mc34704

mc13783 can only communicate via spi, not i2c, so this patch does not
break mx3 + mc13783 case.

Thanks, I have not checked it - I have considered the MC13873 more
similar to the MC13892 as it is ;-).

Then the patch is ok for me.

Applied (whole series) to u-boot-imx, thanks.

This commit introduced a dependency on the PMIC framework, which has
since been reworked in u-boot/master, leading to a failure to merge
u-boot-arm/master and u-boot/master properly.

Fabio, can you look into this?

Stefano, can you add the resulting fix, if any, to the woodburn fixes?

Amicalement,

Hi Fabio, hi Albert,

I have already found this conflict and fixed it (I hope). Fabio, to have
a look, I pushed a temporary "master_merge" branch on u-boot-imx. If
everything is fine, I will push the changes in the master branch as usual.

> Stefano, can you add the resulting fix, if any, to the woodburn fixes?

I hope I have already done without breaking anything.

Best regards,
Stefano

I will be able to access to my mx25pdk next Tuesday and will test your
'master_merge' branch.

I have just sent a patch fixing it.
