[U-Boot] [PATCH v2] OMAP5: I2C: Enable i2c5 clocks

[U-Boot] [PATCH v2] OMAP5: I2C: Enable i2c5 clocks

[Lubomir Popov]

V2 fixes line wrap issue of the patch itself.

I2C5 is used on all known OMAP5 hardware platforms, therefore enable.

This is fine.
Can you also mention what device is connected on them ? and
how you are using it ?

Also can you add these in a series.

On our board we have an I/O expander on I2C5 - the same chip that is used on
the TI sEVM (the handset) and uEVM (the PandaBoard5) platforms (on both of
which it is also connected to I2C5). Therefore it seems reasonable to have
I2C5 enabled in the mainline. This requires that the base address is defined,
and that I2C_BUS_MAX is set to 5 (please see related patches).

I shall do make a new series on I2C5 support.

One more thing I would like to clarify to myself: in your patch series of
Apr. 1 you rename the omap5_evm to omap5_uevm. On the other hand, uEVM was
the TI-internal name for the PandaBoard5, and the evm was known as sEVM.
Doesn't this cause confusion? After all, these are two quite different
hardware platforms.

Thanks and regards,
Lubomir

Moving forward, there is only uEVM and sEVM doesn't exist.

 Thanks for the explanation.
 It would good to have the reasoning in the original commit log.

 For the next one,Tom already answered this. So uEVM is the and also
 the only official.
