Hi Russell:Basically, what I'm suggesting is just this change to imx_hdmi_bind():

I meant that imx_hdmi_bind should be passed these, so that it needs toif so, how about the device tree properties ddc-i2c-bus, reg-io-width,
know nothing about the struct device beyond the generic device structure.
In other words, the dw-hdmi core should not assume that the struct device
is part of a platform device.
they are all found by device?
non-NULL dev->of_node - which is part of the generic device structure.
pass them to imx_hdmi_bind, as the properties ddc-i2c-bus, reg-io-width,
are still can be handled in imx_hdmi_bind ?
int imx_hdmi_bind(struct device *dev, struct device *master,
void *data, struct drm_encoder *encoder,
+ const struct resource *iores, int irq,
const struct imx_hdmi_plat_data *plat_data)
- struct platform_device *pdev = to_platform_device(dev);
- irq = platform_get_irq(pdev, 0);
if (irq < 0)
- iores = platform_get_resource(pdev, IORESOURCE_MEM, 0);
hdmi->regs = devm_ioremap_resource(dev, iores);
and supplying those as arguments from the caller.
