Subject: [PATCH v3 0/4] mfd: cros-ec: Some fixes and improvements.

Dear all,

Basically this is a resend and rebase due that [2] and [3] are currently
merged so all dependecies are in mainline now.

To remmember:

* 1/4 mfd: cros_ec: Get rid of cros_ec_check_features from cros_ec_dev.

As pointed by Lee Jones in this thread [1] we should not use the MFD API
outside of MFD. For this reason the cros-ec-rtc did not get accepted yet.
The reality is that we are calling mfd_add_devices from cros-ec-dev driver
already, so this patch get rid off the MFD calls inside the chardev driver
and moves to cros-ec MFD. Also I think the chardev device should simply
implement the ioctl calls to access to it from userspace.

The above patch involves MFD, IIO and platform chrome subsystems.

* 2/4 mfd: cros_ec: Introduce RTC commands and events definitions
* 3/4 rtc: cros-ec: add cros-ec-rtc driver
* 4/4 mfd: cros_ec: add RTC as mfd subdevice

These patches are the cros-ec RTC driver, 3 and 4 patches are already
acked by the subsystem maintainers involved and are equal to the last
version I send. Patch 5 registers the rtc cell inside the cros-ec MFD
intead of cros-ec-dev chardev driver.

Changes since v2:
- Rebase on top of mainline.
- Removed patch 'mfd: cros-ec: Fix host command buffer size' from series
as was already picked.

Changes since v1:
- Removed patch 'iio: cros_ec_sensors: Fix return value to get raw and
calibbias data' from series as was already picked.
- Removed patch 'iio: cros_ec_sensors: Fix return value to get raw and
calibbias data' from series as was already picked.
- Patch 2/5: Acked-by: Jonathan Cameron <***@...nel.org>
