Hi,
checking some patches thru www.kernel.org
I noticed in
/arch/arm/mach-omap2/cm.c
in function
int omap2_cm_wait_module_ready(s16 prcm_mod, u8 idlest_id, u8 idlest_shift)
...
while (((cm_read_mod_reg(prcm_mod, cm_idlest_reg) & mask) != ena) &&
(i++ < MAX_MODULE_READY_TIME))
udelay(1);
return (i < MAX_MODULE_READY_TIME) ? 0 : -EBUSY;
...
assume MAX_MODULE_READY_TIME==1, if first read&check not good,
we enter inside loop and delay.
If second read&check is good, we exit loop, i==1.
We return -EBUSY Wrong!!
If second read&check is not good, we check i and exit loop, i==2. We return -EBUSY OK!!
Simple correction could be something like
- return (i < MAX_MODULE_READY_TIME) ? 0 : -EBUSY;
+ return (i > MAX_MODULE_READY_TIME) ? -EBUSY : 0;

No reply needed to me,
my spam filter will probably eat your reply.

tag would be nice in kernel.org :)
Not so many kernel hackers give credit these days :(
Happy hacking,
