WLcore - WLAN interface is not up sometimes in Linux

Other Parts Discussed in Thread: WL1835

Hi,

With WL1835 and Linux kernel (3.10.45), sometimes the wlan interface is not showing up.

With wlan interface not coming up case the dmesg shows,

mmc0: no vqmmc regulator found
mmc0: no vqmmc regulator found
mmc0: SDHCI controller on 2190000.usdhc [2190000.usdhc] using ADMA
mmc1: no vqmmc regulator found
mmc1: no vqmmc regulator found
mmc1: SDHCI controller on 2194000.usdhc [2194000.usdhc] using ADMA
mmc0: host does not support reading read-only switch. assuming write-enable.
mmc0: new SDHC card at address e624

In the failure case, if we reset the board it comes up.

In successful case the log shows,

   mmc0: no vqmmc regulator found
   mmc0: no vqmmc regulator found
   mmc0: SDHCI controller on 2190000.usdhc [2190000.usdhc] using ADMA
   mmc1: no vqmmc regulator found
   mmc1: no vqmmc regulator found
   mmc1: SDHCI controller on 2194000.usdhc [2194000.usdhc] using ADMA
   mmc0: host does not support reading read-only switch. assuming write-enable.
   mmc0: new SDHC card at address e624

   mmc1: card claims to support voltages below the defined range. These will be ignored.
   mmc1: queuing unknown CIS tuple 0x91 (3 bytes)
   mmc1: new high speed SDIO card at address 0001

Is there any work around for the failure case without resetting the device to make it work?

Also is there any documents that explains the wlcore stack integration with linux?
