Subject: [PATCH v2 0/4] arm: imx: Add i.mx6q DaSheng COM-9XX SBC board support

From: dillon min <[email protected]>

This patchset aims to add kernel support on DaSheng COM-8XX SBC board
optimize ov2659 driver to handle xvclk on/off at proper stage to save power

changes based on master branch, since commit id:
89698becf06d341a700913c3d89ce2a914af69a2

The DaSheng Com-9xx is and ARM based signle board computer (SBC)
featuring:
- i.MX6Q
- 2GiB LPDDR3 DRAM
- 8GiB eMMC 5.0 FLASH
- 4MiB SPI Flash
- USB 2.0 Host/Device
- Multiple multi-protocol RS232/RS485 Serial ports
- microSD socket
- 5V DC power input
- HDMI1.4a,1080p@60
- RGMIIx1 Gigabit Ethernet
- CSI0x1, connect with ov2659

v2:
- add "[PATCH v2 4/4] dt-bindings: add dasheng vendor prefix" to fix
checkpatch.pl warning.

Subject: [PATCH v2 3/4] media: i2c: ov2659: Add clk_prepare_enable(), clk_disable_unprepare() to handle xvclk

From: dillon min <[email protected]>

For power save purpose, xvclk might not be always on.
need add clk_prepare_enable(), clk_disable_unprepare() at driver
side to set xvclk on/off at proper stage.

Add following changes:
- add 'struct clk *clk' in 'struct ov2659'
- enable xvclk in ov2659_power_on()
- disable xvclk in ov2659_power_off()
