[PATCH 1/6] mfd: arizona: Add TST_CAP bits for headphone detection

[Charles Keepax]

On Florida some additional settings are required to get accurate
measurements at the top end of the headphone detection range. This patch
adds the bits required for this.

[PATCH 2/6] extcon: arizona: Additional settings to improve accuracy of HP detect

[Charles Keepax]

If the TST_CAP_SEL bits aren't set correctly on wm5110/8280 there will
be a 100k load along side the headphones, which will affect the accurary
towards the very top of the detection range. This patch sets those bits.

From: Nariman Poushin <nariman-yzvPICuk2AATkU/dhu1WVueM+bqZidxxQQ4Iyu8u01E@public.gmane.org>

The polarity of MICD_CLAMP_STS does not change when different clamp
modes are used, this patch corrects this issue.

[PATCH 6/6] mfd: arizona: Update DT binding documentation for jack detection

[Charles Keepax]

Add additional bindings for both inverting the polarity of the jack
detection pins and allowing the use of a second jack detection pin. Note
that the second jack detection pin is hard wired in the chip so can only
be enabled through the binding, rather than a pin being specified.

[PATCH 6/6] mfd: arizona: Update DT binding documentation for jack detection

[Charles Keepax]

Add additional bindings for both inverting the polarity of the jack
detection pins and allowing the use of a second jack detection pin. Note
that the second jack detection pin is hard wired in the chip so can only
be enabled through the binding, rather than a pin being specified.

As before, I need an Ack from one of the DT guys, or perhaps Linus W.
