[PATCH v2 0/2] Fix I2C repeated start timing violation on Armada-38x.

[PATCH v2 0/2] Fix I2C repeated start timing violation on Armada-38x.

[Kalyan Kinthada]

All the Armada 38x(380, 385, 388) have a silicon issue in
the I2C controller which violates the I2C repeated start timing
(errata FE-8471889).

Activate the compatible string "marvell,mv78230-a0-i2c" in the
device tree file of Armada-38x to fx this errata (FE-8471889).

Updated the Documentation for the compatible string
"marvell,mv78230-a0-i2c".

Thank You Gregory Clement for suggesting to reuse the
"marvell,mv78230-a0-i2c" compatible string on Armada-38x SoCs.

Changes since v1:
* "dt-bindings: i2c: Update documentation for "mv78230-a0-i2c""
   Modified commit message.
   Added details describing the compatible string "mv78230-a0-i2c"

[PATCH v2 2/2] dt-bindings: i2c: Update documentation for "mv78230-a0-i2c"

[Kalyan Kinthada]

This commit modifies the documentation for
"marvell,mv78230-a0-i2c" compatible string.

The "marvell,mv78230-a0-i2c" compatible string enables the workaround
for an i2c repeated start timing violation, but unlike
"marvell,mv78230-i2c" it disables the i2c offload support. This is
applicable to a number of SoCs such as early revisions of the Armada XP
and the Armada 38x.

I applied the dt fix on my mvebu/fixes branch. Do you want to apply this
one on your branch, or do you prefer I take it. In this case an acked-by
would be nice.

I applied the dt fix on my mvebu/fixes branch. Do you want to apply this
one on your branch, or do you prefer I take it. In this case an acked-by

I'd prefer to take it. What I'd really like to see here is an ack from
Rob because of the previous discussion of an earlier revision of this
patch.

I'm confused how mv78230 relates to Armada XP or 38x... I don't really 
want to know either. If normal compatible string conventions were 
followed then I wouldn't have to.
