Subject: [PATCH v4 0/3] mfd/power: cros_ec: add support for USBPD charger driver.

Dear all,

This is a fourth version of a patched to add support for the ChromeOS EC
USBPD charger driver, the driver has been used on Chromebooks kernel for
long time and has been ported now to mainline. The patches were tested
successfully with a Samsung Chromebook Plus and an Pixel 2 Chromebook.

This version is a rework with respect the first version, some features
like the PD log have been removed and will be send as follow up patches
for further discuss.

The second patch of this series depends on these series that are queued
for 4.18:

- https://lkml.org/lkml/2018/4/23/602 ([PATCH v8 0/6] typec: tcpm: Add
  sink side support for PPS)

The third patch of this series depends on the following patch to apply
cleanly:

- https://lkml.org/lkml/2018/4/18/229 ([RESEND PATCH v5 4/7] mfd:
  cros_ec_dev: Register cros-ec-rtc driver as a subdevice.)

Best regards,
 Enric
