rockchip isp1 driver

[wzyy2]

Rockchip ISP1 driver is a new isp driver for rockchip rk3288/rk3399 SoC, we might use it in future for all linux-kernel based OS, including Android, ChromeOS, Linux...... It's writen in standard v4l2, will be compatible with upstream sensor driver. The development will be last until 2018.04, i hope we could have a working driver, camera hal3, gstreamer plugin at that time.

If you find something is missing in this driver, maybe you could help us add it. ; - p e.g: MIPI TXRX, you can refer to https://github.com/rockchip-linux/kernel/tree/release-4.4/drivers/media/platform/rk-isp10

At present we have some working drivers for linux, but i recommend to not use them especially you don't have commercial support, since it's also buggy and no one can help you......

Status

I have push the new MIPI CSI driver to isp-early-access branch. https://github.com/rockchip-linux/kernel/tree/isp-early-access

upstream status: https://patchwork.linuxtv.org/project/linux-media/list/?submitter=7231

I will maintain this branch until the driver be merged into Rockchip 4.4 kernel/Upstream kernel/ChromeOS kernel. Report bugs are welcome.

Missing feature in this new driver:

• No MIPI-TXRX/ DVP support
• No 3A support

TODO in kernel 4.4:

• Test isp0/isp1 in rk3399 and add dts node
• Test dual isp in rk3399

Test in:

• Tinker Board + imx219/ov5647
• Firefly + HDMI_IN

What is the configuration file for the kernel?

Hi:

I have a question about the return value of the function rkisp1_irq_handler() in the file drivers/media/platform/rockchip-isp1/dev.c.

I think it should return IRQ_HANDLED other than IRQ_NONE, that is: --- a/drivers/media/platform/rockchip-isp1/dev.c +++ b/drivers/media/platform/rockchip-isp1/dev.c @@ -554,7 +554,7 @@ static irqreturn_t rkisp1_irq_handler(int irq, void *cntxt)

    /* TODO: update crop & resize */
    clr_all_int(base);

• return IRQ_NONE;
• return IRQ_HANDLED; }

When the function returns IRQ_NONE, the kernel will output these logs: [ 661.702947] irq 49: nobody cared (try booting with the "irqpoll" option)

Thanks. It should return IRQ_HANDLED, I will add this change.

[axendev]

What changes should I make in DTS for rk3399 ? I have tried do some changes to my DTS file (rk3399-firefly-linux.dts) according to this commit: https://github.com/rockchip-linux/kernel/commit/a804db43b054bb4cb95ccc0eadc906d113ff4000 , but it rises compile-error "mipi_phy_rx0 not defined".

...
&mipi_phy_rx0 {      // There is no definition of lable 'mipi_phy_rx0'
    bus-width = <4>;
    status = "okay";
    port {
        isp_mipi_in: endpoint {
            remote-endpoint = <&camera_out>;
        };
    };
};

For rk3299 mipi_phy_rx0 is defined within 'cif_isp0: cif_isp@ff910000' node in rk3288.dtsi (https://github.com/rockchip-linux/kernel/blob/isp-early-access/arch/arm/boot/dts/rk3288.dtsi#L1126), but 'cif_isp0: cif_isp@ff910000' node in rk3399-linux.dtsi does not contains 'mipi_phy_rx0' (https://github.com/rockchip-linux/kernel/blob/isp-early-access/arch/arm64/boot/dts/rockchip/rk3399-linux.dtsi#L60). Should I modify 'cif_isp0: cif_isp@ff910000' node in rk3399-linux.dtsi like in rk3288.dtsi ?

[wzyy2]

https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/527854/149 Please refer to this for rk3399.

[axendev]

Thank you very much. Can you tell me how I can test this driver in linux? Should I use 'v4l2-ctl' util for this purpose ?

Does rk3399 linux kernel support dual mipi port for ovXXX camera? #47

yes, it should work. I have the same rk3399-firely board but with two imx219 cameras. I modified rockchip-isp1 sources (according to rk-isp10) in order to add mipi-tx1rx1 support. Now it works for each of the two cameras separately (using mipidphy_rx0+isp0 or mipidphy_tx1rx1+isp1). There are several problems with supporting two cameras simultaneously. Firstly, both mipi-conectors on firefly`s board use the same i2c bus, unfortunately the imx219 cameras have identical i2c slave-address and have neither Chip-Select pins nor documented ability of changing slave-addr, so I use external i2c bus switchers IC (each has "enable" pin connected to RK3399 GPIO and controlled by imx219 i2c-driver) to provide switching between several cameras. You might need the same for ovXXX cameras. The current task is to create the correct device-tree nodes for cameras and change the imx219.c i2c-driver to work with them. It is not acceptable to simply create two child-nodes (in 'i2c1' node) for each camera, because both cameras have the same slave address so both camera's nodes will be with identical reg property ("reg" property describes slave address in case of i2c device nodes) which will causes that only one camera will be recognized and probed. If you need, I can provide my sources after I solve these problems.

[gangm]

@axendev , thanks for your recommend and guide, do you mean that I should modify the rockchip-isp1 soures to connect ov cameras? And I should also add the the ov camera's i2c code in the i2c node dir? If you have the worked code, can you provide your sources? Thanks very much!

I use a single ov5647 sensor on rk3288. I managed to setup the kernel and the dts to the point I'm able to probe the sensor correctly:

root@ptam8:~# dmesg | grep ov5647
[    3.206161] i2c i2c-3: of_i2c: register /i2c@ff150000/ov5647@36

However, when I try to capture frames the sensor seems to lose power and i2c r/w returns -6:

v4l2-ctl can't be used now since this driver use media controller api. You have to use rkcamsrc gstreamer plugin to use this driver in linux.

No luck with rkcamsrc either:

I add a new wiki page for rockchip-isp1. http://opensource.rock-chips.com/wiki_Rockchip-isp1

[idreamerhx]

@axendev @wzyy2 thanks for your commit and feedback. I'm working on firefly rk3399 I'm not sure about how to config (or merge) rk3399.dtsi and rk3399-firefly-linux.dts based on chromeos commits. Would you please give me some hint, help or a working copy.

I have 2 ov13850, 1 imx214 and 1 ov5647.

[Triuman]

Will we be able to use IMX219 on TinkerBoard with all features including 3A by 2018.04?

[eddiecailinux]

No promise. Business should go business way. Here is community

[wzyy2]

The driver is merged to release-4.4, so close this issues and delete isp-early-access branch.

3A support on Linux is still in develop.I have add a experimental version to rkcamsrc plugin, but it don't work very well.

[kannant]

I have a issue I am trying to interface mt9v032 using dvp port of rk3399 Firefly board, i am using Android 7.1 can any one help me with drivers,

[SanjayS-ECE]

Hello @axendev , I am also trying to interface dual mipi camera (with same slave addr) with Rk3399 soc,But facing some issue in driver.I mean will I have to write two different drivers for two cameras to probe or a single driver will suffice the requirement.

Thanks
