Hello,
  v8 is rebased on lates renesas-drivers.

Minor changes compared to v7: address Geert's comments on the 'gpio-poc'
property parsing and power enable/disable routine.

The new property parsing logic reads like

	ret = of_property_read_u32_array();
	if (ret == -EVINAL) {
		/* Use regulator */

		return 0;
	}

	/* Make sure the property is well formed. */
	if (ret || gpio_poc[0] > 1 && (gpio_poc[1] != HIGH/LOW)
		return -EINVAL;

	return 0;

Same as in v7:

I have removed depencies on the post_register() v4l2 subdev operation to have
this integrated separately.

This change upports BSP 5.1 commit
https://github.com/renesas-rcar/linux-bsp/commit/28fdde07b28d5ae17ad6fb472ff4b52a4835cbee

The usual note about condor:

Condor has 2 GMSL channels, something the current version of the MAX9286 driver
does not support. However the DTS integration can be upstreamed but a single
channel can be used at a time.

Integration of the new "maxim,gpio-poc" property required for Eagle/Condor is
fully reviewed and can be eventually fast-tracked.

The series has been tested on Eagle V3H board, while only compile tested for
Condor.
