Merge branches 'ib-mfd-4.19', 'ib-mfd-gpio-pinctrl-4.19', 'ib-mfd-i915-media-platform-4.19' and 'ib-mfd-regulator-4.19', tag 'ib-platform-chrome-mfd-move-cros-ec-transport-for-4.19' into ibs-for-mfd-merged Immutable branch (mfd, chrome) due for the v4.19 window Immutable Branch which moves the cros_ec_i2c and cros_ec_spi transport drivers from mfd to platform/chrome. Changes in arm are a simple rename in defconfigs. Change in input is a rename in help text.

The ChromeOS Embedded Controller can expose a CEC bus, this patch add the driver for such feature of the Embedded Controller. This driver is part of the cros-ec MFD and will be add as a sub-device when the feature bit is exposed by the EC. The controller will only handle a single logical address and handles all the messages retries and will only expose Success or Error. The controller will be tied to the HDMI CEC notifier by using the platform DMI Data and the i915 device name and connector name.

This patchs adds the cec_notifier feature to the intel_hdmi part of the i915 DRM driver. It uses the HDMI DRM connector name to differentiate between each HDMI ports. The changes will allow the i915 HDMI code to notify EDID and HPD changes to an eventual CEC adapter.

In non device-tree world, we can need to get the notifier by the driver name directly and eventually defer probe if not yet created. This patch adds a variant of the get function by using the device name instead and will not create a notifier if not yet created. But the i915 driver exposes at least 2 HDMI connectors, this patch also adds the possibility to add a connector name tied to the notifier device to form a tuple and associate different CEC controllers for each HDMI connectors.

The PMIC_DA9063 is a complete misnomer, it denotes the value of the DA9063 chip ID register, so rename it as such. It is also the value of chip ID register of DA9063L though, so drop the enum as all the DA9063 "models" share the same chip ID and thus the distinction will have to be made using DT or otherwise.

Pull block fixes from Jens Axboe: "Small set of fixes for this series. Mostly just minor fixes, the only oddball in here is the sg change. The sg change came out of the stall fix for NVMe, where we added a mempool and limited us to a single page allocation. CONFIG_SG_DEBUG sort-of ruins that, since we'd need to account for that. That's actually a generic problem, since lots of drivers need to allocate SG lists.
