| | | | | | | | | | Find the LPC device in arch_cpu_init_dm() as a first step to converting this code to use driver model. Probing the LPC will probe its parent (the PCH) automatically, so make sure that probing the PCH does nothing before relocation.

| | | | | | | | | | | | | | | At present interrupt routing is set up from arch_misc_init(). We can do it a little later instead, in interrupt_init(). This removes the manual pirq_init() call. Where the platform does not have an interrupt router defined in its device tree, no error is generated. Some platforms do not have this. Drop pirq_init() since it is no-longer used.

* dm: x86: Create a driver for x86 interruptsSimon Glass2016-01-24-0/+26
| | | | | | | | | | | | | | | | It seems likely that at some point we will want a generic interrupt uclass. But this is a big undertaking as it involves unifying code across multiple architectures. As a first step, create a simple IRQ uclass and a driver for x86. This can be generalised later as required. Adjust pirq_init() to probe this driver, which has the effect of creating routing tables and setting up the interrupt routing. This is a start towards making interrupts fit better with driver model.

* dm: x86: spi: Convert ICH SPI driver to driver model PCI APISimon Glass2016-01-24-442/+461
| | | | | | | | | | | | | | | | | | | | | | | | | At present this SPI driver works by searching the PCI buses for its peripheral. It also uses the legacy PCI API. In addition the driver has code to determine the type of Intel PCH that is used (version 7 or version 9). Now that we have proper PCH drivers we can use those to obtain the information we need. While the device tree has a node for the SPI peripheral it is not in the right place. It should be on the PCI bus as a sub-peripheral of the LPC device. Update the device tree files to show the SPI controller within the PCH, so that PCI access works as expected.

| | | | | | | | | | | | | | A Platform Controller Hub is an Intel concept - it is like the peripherals on an SoC and is often in a separate chip from the CPU. The chip is typically found on the first PCI bus and integrates multiple devices. We have a very simple uclass to support PCHs. Add a few operations, such as setting up the devices on the PCH and finding the SPI controller base address. Also move it into drivers/pch/ since we will be adding a few PCH drivers.

Unfortunately this driver is not fully functional. It cannot reliably read EDID information over HDMI. This seems to be due to the clocks being incorrect - the I2C bus speed appears to be up to 100x slower than the clock settings indicate. The root cause may be in the clock logic.
