Hello,

This patch series adds support for the CSIS found in the NXP i.MX8MM SoC
to the imx7-mipi-csis driver.

The CSIS is an IP core from Samsung, integrated in different NXP SoCs.
The driver currently supports v3.3 of the CSIS, found in SoCs from the
i.MX6 and i.MX7 families. This series extends the driver to support
v3.6.3 of the IP, found in i.MX8MM and other members of the i.MX8
family.

The first 21 patches are miscellaneous cleanups and improvements. Please
see individual patches for details.

Patch 22/23 extends the imx7-mipi-csis DT bindings with i.MX8MM support.
Support for other members of the i.MX8 family will come later, and for
SoCs including an ISI IP core (such as the i.MX8MP) this will require
more work to handle additional glue logic.

Patch 23/23 finaly extends the imx7-mipi-csis driver accordingly.

The changes in the integration of the CSIS between i.MX7 and i.MX8, as
described in the DT bindings, have been found through reading of
reference manuals and BSP source code, with different sources of
information contradicting each other. A confirmation from NXP would be
nice (in particular regarding the clocks).
