* x86: broadwell: Add a pinctrl driverSimon Glass2016-03-17-0/+279
| | | | | | | | | | | GPIO pins need to be set up on start-up. Add a driver to provide this, configured from the device tree. The binding is slightly different from the existing ICH6 binding, since that is quite verbose. The new binding should be just as extensible.

* x86: Create a common header for Intel register accessSimon Glass2016-03-17-3/+7
| | | | | | | | | | | | | | There are several blocks of registers that are accessed from all over the code on Intel CPUs. These don't currently have their own driver and it is not clear whether having a driver makes sense. An example is the Memory Controller Hub (MCH). We map it to a known location on some Intel chips (mostly those without FSP - Firmware Support Package). Add a new header file for these registers, and move MCH into it.

* | x86: tnc: Remove IGD and SDVO devices from driver modelBin Meng2016-02-05-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With recent DM PCI changes to vesa_fb driver, external graphics card does not work any more. This is because: after setting the function disable bit, IGD and SDVO devices will disappear in the PCI configuration space. This however creates an inconsistent state from a driver model PCI controller point of view, as these two PCI devices are still attached to its parent's child device list as maintained by the driver model. Some driver model PCI APIs like dm_pci_find_class() used in the vesa_fb driver, are referring to the list to speed up the finding process instead of re-enumerating the whole PCI bus, so it gets the stale cached data which is wrong. To fix this, manually remove these two devices. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
