dm: core: Enable SPL_SIMPLE_BUS by default

2015-12-07T09:14:30+00:00

This option is needed for all SoCs which have nodes on bus. Without
enabling this drivers are not found and probed.
Issue was found on Zynq MMC probe.
Enable this option by default.

(sha1: 83c7e434c9dd3ca81f8b763e23c1881b973bcf2f)

Adds new entries to struct driver and struct uclass_driver without
extending code for manual relocation. This patch fixes it for all
architectures which requires MANUAL_RELOC.

dm: core: Remove unnecessary codes in uclass_pre_remove_device()

2015-10-29T19:05:51+00:00

dev->uclass->uc_drv->per_device_auto_alloc_size is to be freed in
device_free(), so is dev->seq. Remove these unnecessary codes.

functions. Rename it and fix up all users.

dm: core: Enable optional use of fdt_translate_address()

2015-10-21T00:25:01+00:00

The current "simple" address translation simple_bus_translate() is not
working on some platforms (e.g. MVEBU). As here more complex "ranges"
properties are used in many nodes (multiple tuples etc). This patch
enables the optional use of the common fdt_translate_address() function
which handles this translation correctly.

dm: core: Don't use pinctrl for the root device

2015-10-05T14:47:49+00:00

Currently when driver model starts up it finds the root uclass and the
pinctrl uclass. This is because even the root node handles pinctrl
processing.

But this is not useful. The root node is not a real hardware device so
cannot require any particular pinmux settings. Also it means that the
memory leak tests fails, since they end up freeing more memory than
they allocate: the marker it set after the root device and pinctrl
uclass are allocated, and later once the pinctrl uclass is freed the memory
used by driver model is less than when the marker was set.

If a platform needs 'core' pin mulitplex settings it can do this with
a driver that is probed on start-up. It would be an abuse of the root node
to use this for pinctrl.

To avoid this problem, only process pinctrl settings for non-root nodes.

fdt: add new fdt address parsing functions

2015-09-15T13:57:13+00:00

fdtdec_get_addr_size() hard-codes the number of cells used to represent
an address or size in DT. This is incorrect in many cases depending on
the DT binding for a particular node or property (e.g. it is incorrect
for the "reg" property). In most cases, DT parsing code must use the
properties #address-cells and #size-cells to parse addres properties.

This change splits up the implementation of fdtdec_get_addr_size() so
that the core logic can be used for both hard-coded and non-hard-coded
cases. Various wrapper functions are implemented that support cases
where hard-coded cell counts should or should not be used, and where
the client does and doesn't know the parent node ID that contains the
properties #address-cells and #size-cells.

dev_get_addr() is updated to use the new functions.

Core functionality in fdtdec_get_addr_size_fixed() is widely tested via
fdtdec_get_addr_size(). I tested fdtdec_get_addr_size_auto_noparent() and
dev_get_addr() by manually modifying the Tegra I2C driver to invoke them.

Much of the core implementation of fdtdec_get_addr_size_fixed(),
fdtdec_get_addr_size_auto_parent(), and
fdtdec_get_addr_size_auto_noparent() comes from Thierry Reding's
previous commit "fdt: Fix fdtdec_get_addr_size() for 64-bit".
