with lo master branch and zoom3.
Could you please paste your boot log messages here?

Hi paul,
These are the boot log messages.
Is that with the patch applied or without it? If without, please post the
log messages from a boot after you apply the patch.

These logs are with the patch shared by you.
Looks to me like it boots fine. If you had hwmod debugging enabled, your
kernel should have crashed after
omap-hsuart.0: ttyO0 at MMIO 0x4806a000 (irq = 72) is a OMAP UART0
omap-hsuart.1: ttyO1 at MMIO 0x4806c000 (irq = 73) is a OMAP UART1
omap-hsuart.2: ttyO2 at MMIO 0x49020000 (irq = 74) is a OMAP UART2
... but it didn't crash there. I'm not seeing any hwmod debug messages
though, so you probably don't have DEBUG defined in omap_hwmod.c.
So, I suspect whatever problem you're seeing is unrelated to the problem
that the patch was intended to solve.
- Paul
The hwmod debug messages will be seen when I enable them on the go with:
echo -n 'file omap_hwmod.c +p' > /debug/dynamic_debug/control
This will show lots of logs as below ending with UART3 clock disabling
and a hang.
omap_hwmod:omap_hwmod: uart1: idling
omap_hwmod:omap_hwmod: uart1: disabling clocks
omap_hwmod:omap_hwmod: uart2: idling
omap_hwmod:omap_hwmod: uart2: disabling clocks
omap_hwmod:omap_hwmod: uart1: enabling
omap_hwmod:omap_hwmod: uart1: enabling clocks
