Hi Tony and Rogers, thanks for the reply.
I found this:
(clock3xxx_data.c)
static struct clk usbhost_48m_fck = {
.name = "usbhost_48m_fck",
.ops= _omap3430es2_dss_usbhost_wait,
.parent = _48m_fck,
.enable_reg =

Hi Michael,
Thanks for the help,
The clock_summary is not there but I found these files:
$ pwd
/sys/kernel/debug/clock/virt_26m_ck/osc_sys_ck/sys_ck/dpll4_ck/dpll4_m2_ck/dpll4_m2x2_ck/omap_96m_alwon_fck/cm_96m_fck/omap_48m_fck/usbhost_48m_fck
$ cat flags
0x
$ cat
flags rate
Doing some printk mess I found that the usbhost_48m_fck is enabled. So
my problem should be another thing:
clock.c:omap2_dflt_clk_enable@193: usbhost_48m_fck enable_reg value 0x01

Hi
Do you have /sys/kernel/debug/clk/clock_summary?

Hi Michael
About this:
"Two bugs are fixed by this patch. First, OMAP hardware only supports
target CM_IDLEST register bits on ES2+ chips and beyond. ES1 chips
should not wait for these clocks to enable. So, split the appropriate
clocks into ES1 and ES2+ variants, so that kernels

Hi,
Building as built-in doesn't solve my problem. The difference is that
when compiled as module the dump shows up when I load it, and when is
built-in the dump shows up at boot time. Also when built-in the
problem seems to ocurr when device is reseted (on ehci_omap_stop) and
the first stack
Hi
Can you check if you have this patch in?

OMAP3 clock: correct module IDLEST bits: SSI; DSS; USBHOST; HSOTGUSB
Fix two bugs in the OMAP3 clock tree pertaining
I've already tried, it fails to apply. My tree is based on last commit from
TI linux-omap3 (4f1fb3bea4cc381c76e8e439f8af393c1a698dfc) so I *think*
that this is already applied (since come from the same tree).
I will try to apply it by hand
Thanks!

Hi every body!
I'm running a (2.6.37) kernel based on linux-omap tree
(http://arago-project.org/git/projects/?p=linux-omap3.git;a=summary).
The board is a SoM from Variscite (var-som-am3517).
I've compiled the ehci-hcd as a module. When I enable it I got this dump:

Hi Michael,
It's a plain linux. I'm considering upgrading kernel as last option.
Variscite doesn't
support another kernel for this SoM so this would be a really hard
work. I'm looking
for a solution on this kernel and mainly trying to understand why
usbhost_48m_fck
is not getting enabled. I'm
