About set boot_on for clk32kg regulator

[Xiao Jiang <jgq516@gmail.com>]

Hi Kevin,

For panda and blaze, wl12xx sdio card can't be found without set on 
label in struct omap4_clk32kg_idata,
and after search maillist I found Vishal had posted patch for it.
http://marc.info/?l=linux-omap&m=132017988123957&w=2

But after more investigations, if clk32kg regulator isn't on then sdio 
bus can't probe
wl12xx sdio card, which means it isn't possible to enable regulator in 
wl12xx driver.
so I set boot_on as true for 32KG regulator as for power reason as follows.
Is it reasonable or not? or is there other solution can fix this issue? 
thanks.
