[PATCH v6 0/3] IMX274 fixes and power on and off implementation

[Sowjanya Komatineni]

This patch series includes
- Fix for proper Y_OUT_SIZE register configuration.
- Remove sensor i2c register writes to stop stream during remove.
- Power on/off sequence implementation through runtime PM.

Delta between patch versions:
[v6]:	Includes below v5 feedback
	- Added separate small patch to remove i2c writes to stop sensor
	  during remove.
	- Removed dt-binding patch from this series as they are posted by
	  Jacob.
	  https://www.spinics.net/lists/linux-renesas-soc/msg52831.html
	- Uses udelay for 2uS delay after regulators are on before
	  releasing reset.
	- Moved v4l2_ctrl_handler setup to do during start streaming to
	  configure user controls when sensor power is on during streaming.
	- Other minor changes based on v5 feedback.

[v5]:	Includes below v4 feedback
	- dt-bindings patch to add optional clock and supplies and
	  rebased on below json-schema patch.
	  https://patchwork.kernel.org/patch/11732875/
	- Other minor v4 feedbacks.

[v4]:	Includes below v3 feedback
	- Implemented power on/off through Runtime PM.
	- Use regulator bulk APIs.
	- Use lower case for supply names.

[v3]:	Includes below v2 feedback
	- Removed explicit clk_set_rate from driver as default external
	  input clock rate can be configured through DT.

[v2]:	Includes below changes based on v1 feedback
	- External input clock name changed from xclk to inck.
	- implementation change for get regulators to store all in array.
	- To keep in reset low prior to regulators power on.
