dm: Use dm_scan_fdt_dev() directly where possible

2016-07-27T20:15:54+00:00

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.

dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()

2016-07-27T20:15:07+00:00

This new function is more convenient for callers, and handles pre-relocation
situations automatically.

dm: pch: Add get_io_base op

2016-02-05T04:47:21+00:00

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 op

2016-02-05T04:47:21+00:00

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.

Spell out 'sbase' to 'spi_base' so that it looks clearer.

dm: pch: Remove pch_get_version op

2016-02-05T04:47:21+00:00

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: x86: Add a driver for Intel PCH9

2016-01-24T04:07:17+00:00

At some point we may need to distinguish between different types of PCHs,
but for existing supported platforms we only need to worry about version 7
and version 9 bridges. Add a driver for the PCH9.
