Subject: [PATCH 0/4] mfd: intel_soc_pmic_crc: Add crystal_cove_charger cell

Hi All,

While doing a hobby project getting the mainline kernel to work on some
x86 tablets which come with Android pre-installed and which clearly have
never been meant to run Windows (or another generic OS) I encountered an
interesting setup for the bq24190 charger chip IRQ, it is not connected
to the main Bay Trail SoC, instead it runs through a special
external-charger IRQ pin on the CRC PMIC.

This series adds support for that.

Lee, patch 4/4 is included mostly FYI. It depends on current pdx86/for-next
and I plan to merge it through the pdx86 tree.

Patches 1-3 can be merged through the MFD tree indepdently.

Regards,

Hans
