ARM: dts: LogicPD Torpedo: Fix I2C1 pinmux

2018-03-11T15:21:30+00:00

commit 74402055a2d3ec998a1ded599e86185a27d9bbf4 upstream.

The pinmuxing was missing for I2C1 which was causing intermittent issues
with the PMIC which is connected to I2C1.  The bootloader did not quite
configure the I2C1 either, so when running at 2.6MHz, it was generating
errors at time.

This correctly sets the I2C1 pinmuxing so it can operate at 2.6MHz

DM3730 devkit")

ARM: dts: ls1021a: fix incorrect clock references

2018-03-03T09:23:23+00:00

[ Upstream commit 506e8a912661c97b41adc8a286b875d01323ec45 ]

dtc warns about two 'clocks' properties that have an extraneous '1'
at the end:

arch/arm/boot/dts/ls1021a-qds.dtb: Warning (clocks_property): arch/arm/boot/dts/ls1021a-twr.dtb: Warning (clocks_property): Property 'clocks', cell 1 is not a phandle reference in /soc/i2c@2180000/mux@77/i2c@4/sgtl5000@2a

The clocks that get referenced here are fixed-rate, so they do not
take any argument, and dtc interprets the next cell as a phandle, which
is invalid.

ARM: dts: logicpd-somlv: Fix wl127x pinmux

[ Upstream commit cd7594ac3281722cb8f10d6f6c7e4287747c7a9d ]

The pin assignment for the wl127x interrupt was incorrect.  I am
not sure how this every worked.  This also eliminates a conflict with
the SMC911x ethernet driver and properly moves pinmuxes for the
related gpio to omap3_pmx_wkup from omap3_pmx_core.

ARM: dts: Fix omap4 hang with GPS connected to USB by using wakeupgen

2018-02-25T10:05:45+00:00

[ Upstream commit cf87634c8b24e24bf379b8c6807c8b0fb5f23567 ]

There's been a reproducable USB OHCI/EHCI cpuidle related hang on omap4
for a while that happens after about 20 - 40 minutes on an idle system
with some data feeding device being connected, like a USB GPS device or
a cellular modem.

This issue happens in cpuidle states C2 and C3 and does not happen if
cpuidle is limited to C1 state only. The symptoms are that the whole
system hangs and never wakes up from idle, and if a watchdog is
configured the system reboots after a while.

Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC
interrupt controller directly as a parent instead of the WUGEN. We
need to pass the interrupts through WUGEN to GIC to provide the wakeup
events for the processor.

Let's fix the issue by removing the gic interrupt-parent and use the
default interrupt-parent wakeupgen instead. Note that omap5.dtsi had
this already fixes earlier by commit 7136d457f365 ("ARM: omap: convert
wakeupgen to stacked domains") but we somehow missed omap4 at that
point.

ARM: dts: Delete bogus reference to the charlcd

2018-02-22T14:43:56+00:00

commit 586b2a4befad88cd87b372a1cea01e58c6811ea9 upstream.

The EB MP board probably has a character LCD but the board manual does
not really state which IRQ it has assigned to this device. The invalid
assignment was a mistake by me during submission of the DTSI where I was
looking for the reference, didn't find it and didn't fill it in.

Delete this for now: it can probably be fixed but that requires access
to the actual board for some trial-and-error experiments.
