* dm: Use dm_scan_fdt_dev() directly where possibleSimon Glass2016-07-27-12/+1
| | | | | | | Quite a few places have a bind() method which just calls dm_scan_fdt_dev(). We may as well call dm_scan_fdt_dev() directly. Update the code to do this. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()Simon Glass2016-07-27-3/+1
| | | | | | | This new function is more convenient for callers, and handles pre-relocation situations automatically. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: pch: Add get_io_base opBin Meng2016-02-05-0/+11
| | | | | | | | | | On some newer chipset (eg: BayTrail), there is an IO base address register on the PCH device which configures the base address of a memory-mapped I/O controller.

* dm: pch: Add get_gpio_base opBin Meng2016-02-05-0/+11
| | | | | | | | | | x86 GPIO registers are accessed via I/O port whose base address is configured in a PCI configuration register on the PCH device. Add an op get_gpio_base to get the GPIO base address from PCH. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>

| | | | | | | | 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>
* dm: pch: Remove pch_get_version opBin Meng2016-02-05-10/+0
| | | | | | | | | | | | | 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.

* dm: Expand the uclass for Platform Controller Hubs (PCH)Simon Glass2016-01-24-0/+62
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.
