[PATCH v2] arm: omap3: cm-t35: add support for cm-t3730
cm-t3730 is basically the same board as cm-t35, but has DM3730 SoC
assembled and therefore some changes are required.

[PATCH] OMAP: don't trace functions called from sched_clock
omap_readl() is used from the sched_clock() implementations and so must
be marked notrace to avoid recursion in ftrace. Same thing with
mpu_read() for OMAP1.

Signed-off-by: Graeme Gregory g...@slimlogic.co.uk I don't see the point of this patch. It's just a string. Use the same name and add a comment saying that on datasheet/TRM/documentation the name LDO is actually referred to as LDOUSB. It's the same functionality anyway. I think for the avoidance of any doubt, it's probably best to use the TWL6025 string name here as it will importantly match the TWL6025 TRM and any schematics using the TWL6025. Getting this wrong during TWL6025 board integration has the potential for hardware damage.

OMAP1: unnecessary timer interrupt handler code?
MPU timer 2 is used on OMAP1 for the clock source and scheduler clock.
It registers an interrupt, which counts the number of overflows of
this timer. However, this counter is only referenced by the interrupt
handler.
So, it seems that the following code serves very little purpose. Can
it be simply deleted?
static unsigned long omap_mpu_timer2_overflows;
static irqreturn_t omap_mpu_timer2_interrupt(int irq, void *dev_id)
{
omap_mpu_timer2_overflows++;
return IRQ_HANDLED;
}
static struct irqaction omap_mpu_timer2_irq = {
.name = mpu_timer2,
.flags = IRQF_DISABLED,
.handler= omap_mpu_timer2_interrupt,
};
...
static void __init omap_init_clocksource(unsigned long rate)
{
...
setup_irq(INT_TIMER2, omap_mpu_timer2_irq);
...
}

You need a more clever way of handling this. Maybe passing an array of regulators and the array size instead of continuously adding fields to this structure. Ok, I agree that optimising the platform data here is desirable, but I think we will have to stick with this atm as the twl driver has some rather annoying limitations that make optimising things like this a pita atm. I guess we should look at fixing the twl driver within TI in order to make it more adaptable (i.e. support future twl ICs) and also a non singleton device.
