mvtwsi: Fix breakage introduced by "Fix mvtwsi not working on sun6i and newer sunxi SoCs"

2016-01-26T16:58:02+00:00

"Fix mvtwsi not working on sun6i and newer sunxi SoCs" includes the following:

@@ -189,7 +200,8 @@ static int twsi_start(struct i2c_adapter *adap, int expected_status)
 	/* globally set TWSIEN in case it was not */
 	twsi_control_flags |= MVTWSI_CONTROL_TWSIEN;
 	/* assert START */
-	writel(twsi_control_flags | MVTWSI_CONTROL_START, &twsi->control);
+	twsi_control_flags |= MVTWSI_CONTROL_START | MVTWSI_CONTROL_CLEAR_IFLG;
+	writel(twsi_control_flags, &twsi->control);
 	/* wait for controller to process START */
 	return twsi_wait(adap, expected_status);
 }

The modification of twsi_control_flags done here was introduced while
merging to fix a line > 80 chars, but twsi_control_flags is a global variable
and should not be modified like this here, this commit fixes this, restoring
mvtwsi functionality.

x86: i2c: Add a stub driver for Intel I2C/SMbus

2016-01-24T04:09:40+00:00

This is used on most Intel platforms. We don't have a driver for it yet, but
add a stub to handle the init. For now this targets ivybridge so we may want
to add a device tree binding and generalise it when other platforms are
supported.

dm: i2c: Allow muxes to be enabled for SPL separately

2016-01-22T03:42:35+00:00

Since I2C muxes are seldom needed in SPL, and the code for this increases
the size somewhat, add a separate option to enable I2C muxes for SPL.

In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier

arm: mvebu: Move SoC selection (A38X vs AXP) into Kconfig

2016-01-14T13:08:59+00:00

Until now, the SoC selection for the ARCH_MVEBU platforms has been done
in the config header. Using CONFIG_ARMADA_XP in a non-clear way. As
it needed to get selected for AXP and A38x based boards. This patch
now changes this to move the SoC selection to Kconfig. And also
uses CONFIG_ARCH_MVEBU as a common define for both AXP and A38x.
This makes things a bit clearer - especially for new board additions.

Additionally the defines CONFIG_SYS_MVEBU_DDR_AXP and
CONFIG_SYS_MVEBU_DDR_A38X are replaced with the already available
CONFIG_ARMADA_38X and CONFIG_ARMADA_XP.

And CONFIG_DDR3 is removed, as its not referenced anywhere.
