Subject: [PATCH v4 0/3] media: imx: add support for imx8mq MIPI RX

hi,

This patch series adds a driver for the i.MX8MQ CSI MIPI receiver / controller.

It includes the driver, the dt-bindings and the DT addition to the SoC dtsi.

This is the vendor driver I'm basing the hardware-side of the driver on:
https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/platform/imx8/mxc-mipi-csi2_yav.c?h=imx_5.4.70_2.3.0

Thanks Laurent who helped a lot. I'm happy for any feedback,

                           martin

revision history
----------------
v4: (thank you Rob and Marco)
* create fsl,mipi-phy-gpr custom dt property instead of confusing "phy"
* add imx8mq-specific compatibile to imx8mq.dtsi for future use

v3: (thank you, Rob and Laurent)
among minor other things according to v2 review, changes include:
* better describe the clocks
* rename DT property "phy-reset" to "reset" and "phy-gpr" to "phy"

v2: (thank you, Dan and Guido)
among fixes according to v1 reviews, changes include:
* remove status property from dt-bindings example
* define a few bits in order to have less magic values
* use "imx8mq_mipi_csi_" as local function prefix
* read DT properties only during probe()
* remove dead code (log_status)
* add imx8mq_mipi_csi_release_icc()
* fix imx8mq_mipi_csi_init_icc()
