Just for the record, I'm definitely happy with the way this is turning out, don't see my question on the serial driver as a NAK. I assume we will apply the patches for 3.14, but I first want to have a better understanding on where we are with the stuff that is already queued up for 3.14.

I chose to split the Dragonboard patch up into two patches instead of one: One that adds SoC support, and a second that adds the board support. I rephrased commit messages accordingly but the contents was untouched (just split up). I hope the clock stuff can be sorted out real quick so we get working support for more useful IP on the SoC in time for 3.14. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

He's not, dev_get_regmap() just gets a pointer to an existing regmap - no reference is taken and nothing is allocated. It's a helper that's mainly there so that generic code can be written without needing the regmap to be passed around. The caller is responsible for ensuring that it will stick around for as long as it's used (generally by having it lifetime managed with the device). signature.asc Description: Digital signature

[PATCH v2 00/10] Use regmap+devm+DT in pm8xxx input drivers
These patches move the pm8xxx input drivers over to use devm_* APIs and regmap. This breaks the dependency of these drivers on the pm8xxx specific read/write calls and also simplifies the probe code a bit. Finally we add devicetree support to these drivers so they can be probed on the platforms that are supported upstream. There was no devm_request_any_context_irq() available, so I've added it here.

[PATCH v2 04/10] Input: pmic8xxx-keypad - Migrate to regmap APIs
Use the regmap APIs for this driver instead of custom pm8xxx APIs. This breaks this driver's dependency on the pm8xxx APIs and allows us to easily port it to other bus protocols in the future.
