clk_table is used to set clock source in each mode, as well as limitation,
max_rate and init rate.
It concerned many experts though, and Seungwon recommended some limitation can

So wlan probe function should be called for re-downloading, is it be

Not really;
I assume you refer to libertas_sdio, which AFAICT, is built to power

Hi, Ohad
One question :(
Under pm_runtime mechanism, how to dynamically open/close wlan.
If the wlan chip really power off, the firmware should be reloaded,

Hi Subhash,
Does your controller follow some non-standard steps for initialization?
I referred to Figure 3-14
