We found freescale imx6 and rockchip rk3288 and Ingenic JZ4780 (Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly difference, such as phy pll configuration, register width(imx hdmi register is one byte, but rk3288 is 4 bytes width and can only access by word), 4K support(imx6 doesn't support 4k, but rk3288 does).
To reuse the imx-hdmi driver, we do this patch set: patch (1): split out imx-soc code from imx-hdmi to dw_hdmi-imx.c patch (2): move imx-hdmi to bridge/, and rename to dw-hdmi to make this driver indepent of drm-imx . And we will add rockchip platform specific code dw_hdmi-rockchip.c later, this is depend on drm-rockchip.
Changes in V2: - use git format-patch -M to generate these patch - remove change-id - remove from

imx6 and rockchip rk3288 and JZ4780 (Ingenic Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly difference, such as phy pll configuration, register width(imx hdmi register is one byte, but rk3288 is 4 bytes width), 4K support(imx6 doesn't support 4k, but rk3288 does), clk useage,and the crtc mux configuration is also platform specific.
To reuse the imx hdmi driver, split the platform specific code out to dw_hdmi-imx.c.

Hi Andy,
I think separating the core from the SoC specific part is a good step into the right direction.

imx6 and rockchip rk3288 and JZ4780 (Ingenic Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly difference, such as phy pll configuration, register width(imx hdmi register is one byte, but rk3288 is 4 bytes width), 4K support(imx6 doesn't support 4k, but rk3288 does), clk useage,and the crtc mux configuration is also platform specific.
To reuse the imx hdmi driver, split the platform specific code out to dw_hdmi-imx.c.

Do you really need to use readl instead of readb? In my opinion it would be better then to convert the driver to use regmap for register access (in a separate patch) and then let the SoC specific driver extension provide the regmap to the core driver.

Surely this IP core needs to be clocked regardless of the SoC? How are clocks controlled on rk3288 and jz4780?
yes, this IP core need to be clocked. But different Soc has different usage of the clk, on freescale imx platform one clk is used for isfr, one is used for iahb, but on rockchip rk3288, one clk is used for control logic , the another is used for hdcp. I am not sure how are the clocks on jz4780

Do you really need to use readl instead of readb? In my opinion it would be better then to convert the driver to use regmap for register access (in a separate patch) and then let the SoC specific driver extension provide the regmap to the core driver.
Rockchip RK3288 can only access the hdmi register by 32bit(readl/writel) byte access(readb/writeb) will cause an imprecise external abort
I refactor the register access in PATCH V3, if you have any suggestion,please tell me.

For a header file in include/drm/bridge maybe these struct names are a bit too generic now.

We found freescale imx6 and rockchip rk3288 and Ingenic JZ4780 (Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly difference, such as phy pll configuration, register width(imx hdmi register is one byte, but rk3288 is 4 bytes width and can only access by word), 4K support(imx6 doesn't support 4k, but rk3288 does).
To reuse the imx-hdmi driver, we do this patch set: patch (1): split out imx-soc code from imx-hdmi to dw_hdmi-imx.c patch (2): move imx-hdmi to bridge/, and rename to dw-hdmi to patch (3): add multi byte register access support make this driver indepent of drm-imx . And we will add rockchip platform specific code dw_hdmi-rockchip.c later, this is depend on drm-rockchip.
Changes in V3: - refactor multi byte register access, and split it to one indepent patch - convert it to a drm_bridge driver
Changes in V2: - use git format-patch -M to generate these patch - remove change-id - remove from
Andy Yan (3): imx-drm: imx-hdmi: split imx soc specific code from imx-hdmi dw-hdmi: move imx-hdmi to bridge/dw-hdmi dw-hdmi: add support for multi byte register width access

We need a "real" name here, sorry.
dw-hdmi is under drm/bridge, so it should be the bridge mode. hange off the encoder to dw_hdmi-imx.c, keep the connector & birdge in dw_hdmi.c

Same here.
thanks,

Sorry, these will be fixed in V4. And tks for you pointing it out.
We found freescale imx6 and rockchip rk3288 and Ingenic JZ4780 (Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly difference, such as phy pll configuration, register width(imx hdmi register is one byte, but rk3288 is 4 bytes width and can only access by word), 4K support(imx6 doesn't support 4k, but rk3288 does).
To reuse the imx-hdmi driver, we do this patch set: patch (1): split out imx-soc code from imx-hdmi to dw_hdmi-imx.c patch (2): move imx-hdmi to bridge/, and rename to dw-hdmi to make this driver indepent of drm-imx . And we will add rockchip platform specific code dw_hdmi-rockchip.c later, this is depend on drm-rockchip.
Changes in V4: - return defer if can't get ddc i2c adapter - fix checkpatch warns
Changes in V3: - refactor multi byte register access, and split it to one indepent patch - convert it to a drm_bridge driver
Changes in V2: - use git format-patch -M to generate these patch - remove change-id - remove from
Andy Yan (5): imx-drm: imx-hdmi: split imx soc specific code from imx-hdmi dw-hdmi: move imx-hdmi to bridge/dw-hdmi dw-hdmi: make checkpatch happy dw-hdmi: return defer if can't get ddc i2c adapter dw-hdmi: add support for multi byte register width access

imx6 and rockchip rk3288 and JZ4780 (Ingenic Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly difference, such as phy pll configuration, register width, 4K support, clk useage, and the crtc mux configuration is also platform specific.
To reuse the imx hdmi driver, split the platform specific code out to dw_hdmi-imx.c.

This should throw an error if the property value in devicetree is not recognized. This could be simplified like this:
u32 val = 1;
// this won't touch val if it can't find the property of_property_read_u32(np, "reg-io-width", &val)
switch (val) { case 4: hdmi->write = dw_hdmi_writel; hdmi->read = dw_hdmi_readl; hdmi->reg_shift = 2; break; case 1: hdmi->write = dw_hdmi_writeb; hdmi->read = dw_hdmi_readb; hdmi->reg_shift = 0; break; default: dev_err(dev, "unrecognized value for reg-io-width"); // error handling }
Also the DT binding doc for this property is missing.

thanks for your suggestion, I will take it. this properity is optional, I will add it to DT binding doc
