Hi
You should find the twl4030 power script and you should have something like this
static struct twl4030_ins wrst_seq[] __initdata = {
{MSG_SINGULAR(DEV_GRP_NULL, 0x1b, RES_STATE_OFF), 2},
{MSG_SINGULAR(DEV_GRP_P1, 0xf, RES_STATE_WRST), 15},
{MSG_SINGULAR(DEV_GRP_P1, 0x10, RES_STATE_WRST), 15},
{MSG_SINGULAR(DEV_GRP_P1, 0x7, RES_STATE_WRST), 0x60},
{MSG_SINGULAR(DEV_GRP_P1, 0x19, RES_STATE_ACTIVE), 2},
{MSG_SINGULAR(DEV_GRP_NULL, 0x1b, RES_STATE_ACTIVE), 2},
};
static struct twl4030_script wrst_script __initdata = {
.script = wrst_seq,
.size = ARRAY_SIZE(wrst_seq),
.flags = TWL4030_WRST_SCRIPT,
};
static struct twl4030_script *omap3_power_scripts[] __initdata = {
&wrst_script,
};
If I remember it was solved by some change here. In my old kernel I
have this commit
Fix the reboot at lower frequency

But this apply on an old device with a newer kernel and I don't
remember now the reason ;) Sorry.
Is this an android device? (2.6.37??? is really old)
