Message-ID<pYOOl-774-5@gated-at.bofh.it>
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

#1209245 — [PATCH v2 1/6] ARM: dts: ifc6410: Add pwrseq support for WLAN

Subject[PATCH v2 1/6] ARM: dts: ifc6410: Add pwrseq support for WLAN
Message-ID<pYOOm-774-29@gated-at.bofh.it>
In reply to#1209243
This patch adds pwrseq for WLAN which resets the WLAN just before the
SDIO bus is up.
