Can you help us with above problem? How to catch external abort

Actually it's a synchronous bus error that you want to catch, which
however is misreported by linux as
we have i2c0 sleep pinctrl state but were passing
default state anyhow. Fix that.

This patch changes the dtc grammar to allow following syntax
i2cexp: i2c2 {
...
};
Current device tree compiler allows to define multiple labels when defining
the device node the first time. Typically device nodes are defined in
DTSI files. Now these nodes can be overwritten for updating
Hi,
Do we have support for LED controllers which can handle patterns of
different kinds ? I mean, currently, if we have an LED controller such
as TPIC2810 [1] which can control 8 different leds and each LED
corresponds to one bit on register 0x44, we could control leds by just
playing a wave file
Hi,

As it turns out, tps62362 is actually on I2C bus0,
not bus1. This has gone unnoticed because Linux
doesn't use (as of now) that regulator at all, it's
setup by the bootloader and left as is.
While at that, also add missing reg property for
our regulator.
