[PATCH v2 0/6] DT: APQ8064 for qcom-dt-next

[PATCH v2 0/6] DT: APQ8064 for qcom-dt-next

[Srinivas Kandagatla]

Hi Andy,

Apologies for the long delay in sending new version of the patches.
Here are the new patches with fixes and dropping the MDP and panel
related changes.

Some dt patches which depend on pmic header
 "dt-bindings/pinctrl/qcom,pmic-gpio.h" which is availble in linux-next.


Changes since v1(https://lkml.org/lkml/2015/7/28/489)
 - Fixed style related errors spotted by Stephen and Bjorn
 - dropped mdp and Panel related DT, as it seems to go no where
  w.r.t cleaning up the driver.
 - Added few more patches for qs600 which are very trival.

 thanks,
 srini

[PATCH v2 1/6] ARM: dts: ifc6410: Add pwrseq support for WLAN

[Srinivas Kandagatla]

This patch adds pwrseq for WLAN which resets the WLAN just before the
SDIO bus is up.

[PATCH v2 2/6] ARM: dts: qs600: add pwrseq support to WLAN

[Srinivas Kandagatla]

Add pwrseq support to sdcc4 which would enable a proper reset of WLAN
without ugly hacks in the board support file.

Why do we need any of these three properties?

Especially because this node doesn't have a reg property.

I have a whole set of patches to add all the serial aliases and
