2016-02-05x86: pch: Implement get_gpio_base opBin Meng
Implement get_gpio_base op for bd82x6x, pch7 and pch9 drivers. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
2016-02-05dm: pch: Rename get_sbase op to get_spi_baseBin Meng
Spell out 'sbase' to 'spi_base' so that it looks clearer. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
2016-02-05dm: pch: Remove pch_get_version opBin Meng
pch_get_version op was only used by the ich spi controller driver, and does not really provide a good identification of pch controller so far, since we see plenty of Intel PCH chipsets and one differs from another a lot, which is not simply either a PCHV_7 or PCHV_9. Now that ich spi controller driver was updated to not get such info from pch, the pch_get_version op is useless now.

2016-01-24x86: ivybridge: Use syscon for the GMA deviceSimon Glass
Until we have a proper video uclass we can use syscon to handle the GMA device, and avoid the special device tree and PCI searching. Update the code to work this way. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2016-01-24x86: Set up a shared syscon numbering schemaSimon Glass
Each system controller can have a number to identify it. It can then be accessed using syscon_get_by_driver_data(). Put this in a shared header file and update the only current user. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

This is not needed. On reset wake-on-disconnect is already set. It may a problem during a soft reset or resume, but for now it does not seem important.

2016-01-24dm: x86: spi: Convert ICH SPI driver to driver model PCI APISimon Glass
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.
