Add initial support for the Synopsys DesignWare HDMI RX
Controller Driver used by Rockchip RK3588. The driver
supports:
- HDMI 1.4b and 2.0 modes (HDMI 4k@60Hz)
- RGB888, YUV422, YUV444 and YCC420 pixel formats
- CEC
- EDID configuration
The hardware also has Audio and HDCP capabilities, but these are
not yet supported by the driver.

Hi,
+ hdmirx_dev->dev = dev;
+ dev_set_drvdata(dev, hdmirx_dev);
+
+ ret = hdmirx_parse_dt(hdmirx_dev);
+ if (ret)
+ return ret;
+
+ ret = hdmirx_setup_irq(hdmirx_dev, pdev);
+ if (ret)
+ return ret;
From here, should of_reserved_mem_device_release() be called in the
error handling path, as done in the remove function?
+
+ hdmirx_dev->regs = devm_platform_ioremap_resource(pdev, 0);
+ if (IS_ERR(hdmirx_dev->regs))
+ return dev_err_probe(dev, PTR_ERR(hdmirx_dev->regs),
+ "failed to remap regs resource\n");
...
+static const struct of_device_id hdmirx_id[] = {
+ { .compatible = "rockchip,rk3588-hdmirx-ctrler" },
+ { },
Unneeded trailing comma after a terminator.
+};
+MODULE_DEVICE_TABLE(of, hdmirx_id);
...
+ ret = cec_register_adapter(cec->adap, cec->dev);
+ if (ret < 0) {
+ dev_err(cec->dev, "cec register adapter failed\n");
+ cec_unregister_adapter(cec->adap);
Is it needed to call cec_unregister_adapter() when
cec_register_adapter() fails?
+ return NULL;
+ }
+
+ irqs = CECTX_LINE_ERR | CECTX_NACK | CECRX_EOM | CECTX_DONE;
+ hdmirx_cec_write(cec, CEC_INT_MASK_N, irqs);
+
CJ
