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
---
v3:
- optimize commit message for patch v3 ov2659 part
- move 'imx6q-ds.dtb' after 'imx6q-dms-ba16.dtb' to follow the alphabetical order
(arch/arm/boot/dts/Makefile)
- move 'ds,imx6q-sbc' after 'dmo,imx6q-edmqmx6' to follow the alphabetical
order. (Documentation/devicetree/bindings/arm/fsl.yaml)
- move v2 patch 4 to v3 patch 1
- add 'Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>'

You are setting the LDB clock parent, but you don't use LDB in this
devicetree. You could simply remove this.

This could be part of the pinctrl_ov2659 group as it provides the
clock for the camera.
Please try to keep in the hoggrp only the pins that cannot be
controlled by any other node.

Wouldn't it be better to enable wdog2 and disable wdog1 instead? wdog2
provides a POR, which is preferred.

Agree, after moving these pinctrl to corresponding component's group,
the hoggrp is useless.
so, I removed it in v4.

* [PATCH v3 4/4] media: i2c: ov2659: Use clk_{prepare_enable,disable_unprepare}() to set xvclk on/off

From: dillon min <dillon.minfei@gmail.com>
On some platform(imx6q), xvclk might not switch on in advance,
also for power save purpose, xvclk should not be always on.
so, add clk_prepare_enable(), clk_disable_unprepare() in 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()
