All,
I'm trying to get OTG to work using the latest PM branch (created by
cloning
git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm.git,
commit ID 12323321f004c9e83061c9a9d06046b050d6d4c77).
I started with the rk51 board, and brought up serial, ethernet for
NFSroot, added the following to setup the OTG MUX
arch/arm/mach-omap2/mux.c:
// MUSB port 0
MUX_CFG_34XX("T28_3430_USB0HS_PHY_CLK", 0x1a2,

The following is called before usb_musb_init in the board file:
// Initialize the mux for the MUSB
static void musb_mux_init(void)
{
/* Port 0 */
omap_cfg_reg(T28_3430_USB0HS_PHY_CLK);
omap_cfg_reg(T25_3430_USB0HS_PHY_STP);
omap_cfg_reg(R28_3430_USB0HS_PHY_DIR);
omap_cfg_reg(T26_3430_USB0HS_PHY_NXT);
omap_cfg_reg(T27_3430_USB0HS_PHY_D0);
omap_cfg_reg(U28_3430_USB0HS_PHY_D1);
omap_cfg_reg(U27_3430_USB0HS_PHY_D2);
omap_cfg_reg(U26_3430_USB0HS_PHY_D3);
omap_cfg_reg(U25_3430_USB0HS_PHY_D4);
omap_cfg_reg(V28_3430_USB0HS_PHY_D5);
omap_cfg_reg(V27_3430_USB0HS_PHY_D6);
omap_cfg_reg(V26_3430_USB0HS_PHY_D7);
}
And I verified that it is indeed called(fromn the log):

When I fire up the kernel w/o a device plugged in, then plug in a
device, it fails to detect the insertion event. Also, if I fire it up
with a hub plugged in, it detects the hub, but no downstream devices.
I see the following on startup(with debug set to 4, hub plugged in with
card reader downstream of the hub). It looks like the usb can see the
hub, but doesn't detect (or power up) any devices downsteam of the hub:

1) Has anyone gotten the MUSB in the latest PM branch working?
2) Outside of setting up the pinmux, is there anything else necessary to
get the MUSB to come up?
3) Any ideas on how to fix this?
