[PATCH 0/4] Moto G (2013) DTS updates

[PATCH 0/4] Moto G (2013) DTS updates

[Stanislav Jakubek]

This series improves the accuracy of motorola-falcon's DTS.

As a side note, I wanted to ask how to describe the Hall effect sensor's
vdd-supply. The sensor's currently described as part of the gpio-keys node.
According to the schematic it's powered by pm8226_lvs1, but I don't see a way
to describe this as part of the gpio-keys node (maybe it's always-on because
of this? Downstream describes it as gpio-keys too). Any tips?

[PATCH 1/4] ARM: dts: qcom: msm8226-motorola-falcon: add clocks, power-domain to simpleFB

[Stanislav Jakubek]

Makes the display work without clk_ignore_unused and pd_ignore_unused.

[PATCH 2/4] ARM: dts: qcom: msm8226-motorola-falcon: add I2C clock frequencies

[Stanislav Jakubek]

While the currently supported hardware works fine with the default clock
frequencies of 100000 on both I2C2 and I2C3, downstream sources list the
frequencies as 100000 for I2C2 and 400000 for I2C3. Update them as such.

[PATCH 3/4] ARM: dts: qcom: msm8226-motorola-falcon: limit TPS65132 to 5.4V

[Stanislav Jakubek]

After some digging in downstream sources, it was found that the TPS65132
outputs are fixed to +5.4V and -5.4V respectively. This is further confirmed
on runtime through debugfs, the troubleshooting guide confirms this as well.
Specify these limits as such.

[PATCH 4/4] ARM: dts: qcom: msm8226-motorola-falcon: specify vddio_disp output voltage

[Stanislav Jakubek]

After some digging in downstream sources, it was found that the vddio_disp
regulator's output voltage is 1.8V. This is further confirmed by the
troubleshooting guide. Specify its output voltage as such.
While at it, add a comment specifying the IC, which according to the
schematic is the TI TPS22902.

Not sure what the troubleshooting guide you're referring to is, but
nonetheless
