These 3 patches are included to fix the following issues
with pepper device tree source. The patches are based against
linux-omap/master.
Adam YH Lee (2):
ARM: dts: Correct audio input route & set mic bias
ARM: dts: configure regulators for Gumstix Pepper
Arun Bharadwaj (1):
ARM: dts: Fix frequency scaling on Gumstix Pepper.

Audio-in was incorrectly routed to Line In. It should be Mic3L as per
schematic.
Using mic-bias voltage at 2.0v (<0x1>) does not work for some reason. There
is no voltage seen on micbias (R127). Mic-bias voltage of 2.5v (<0x2>) works.
I see voltage of 2.475v across GND and micbias.
With these changes, I can record audio with a pair of proliferate TRRS earbuds.

Boot process is halting in midway because some of the necessary voltage
regulators are deemed unused and subsequently powered off, leading to
a completely unresponsive system.
Most of the device nodes had correct voltage regulator attachments.
Yet these nodes had to set stricter enforcement on them through
'regulator-boot-on' and 'regulator-always-on' to function correctly.

The device tree for Gumstix Pepper has DCDC2 and
DCDC3 correctly labelled but the upper limit values
are wrong. The confusion is due to the hardware
quirk where the DCDC2 and DCDC3 wires are flipped
in Pepper.

That's a lot of regulators marked as regulator-always-on. Could
you please update the description what consumers are using them
so we know why they are all needed always-on?

I reviewed Adam's original patch internally at Gumstix and my

I tested this series on top of linus/master with omap2plus_defconfig and
it seems to successfully boot now (used to hang after disabling
vdd_mpu.)
However, it still hangs during boot when testing with multi_v7_defconfig
(boot log below.)
Anyways, it's a step in the right direction. Feel free to add

I tested this series on top of linus/master with omap2plus_defconfig and
it seems to successfully boot now (used to hang after disabling
vdd_mpu.)
However, it still hangs during boot when testing with multi_v7_defconfig

I tested this series on top of linus/master with omap2plus_defconfig and
it seems to successfully boot now (used to hang after disabling
vdd_mpu.)
However, it still hangs during boot when testing with multi_v7_defconfig
(boot log below.)
Anyways, it's a step in the right direction. Feel free to add
