Hi,
I'm trying to make wifi working on pandaboard (A2). I'm trying to use
vanilla 4.6-rc7 (omap2plus_defconfig) + device tree. wl21xx seems it's
not probed on sdio due to the missing clk32k. I got some inspiration
from omap5-evm to create simple pwrseq + define clk32k for twl6040.
Not sure if this is right approach but warning about clk32k is gone
with below patch:
[ 2.249786] twl6040 0-004b: clk32k is not handled
[ 2.258575] of_get_named_gpiod_flags: parsed 'ti,audpwron-gpio'
property of node '/ocp/i2c@48070000/twl@4b[0]' - status (0)
[ 2.542816] vwl1271: disabling

after this change wifi it's still not working. Any ideas or anyone has
it working? Many thanks.
