[PATCH v2 0/5] mfd: cros-ec: Some fixes and improvements.

[Enric Balletbo i Serra]

Dear all,

This is another patch series to fix and improve some cros-ec mfd related
things.

 * 1/5 mfd: cros-ec: Fix host command buffer size

  This patch is a FIX, and I think that would be interesting see it merged
in this release cycle. This should go through the MFD tree and can be picked
independently of the other patches. Lee Jones I think this is for you.

 * 2/5 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.

 * 3/5 mfd: cros_ec: Introduce RTC commands and events definitions
 * 4/5 rtc: cros-ec: add cros-ec-rtc driver
 * 5/5 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.

 Note that these 3 patches depends on [2] to build. I recommend apply
these series on top of [3]

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 <jic23@xxxxxxxxxx>
