dm: avoid dropping pin control DT properties in case of SPL_PINCTRL

2017-04-05T02:15:10+00:00

This patch replaces SPL_PINCTRL_FULL with SPL_PINCNTRL. It is to avoid removal
of pin control properties in case of SPL_PINCTRL. No impact in case of
SPL_PINCTRL_FULL as it depends on SPL_PINCTRL.

dm: Add callback to modify the device tree

2017-03-23T14:46:23+00:00

Certain boards come in different variations by way of utilizing daughter
boards, for example. These boards might contain additional chips, which
are added to the main board's busses, e.g. I2C.

The device tree support for such boards would either, quite naturally,
employ the overlay mechanism to add such chips to the tree, or would use
one large default device tree, and delete the devices that are actually
not present.

Regardless of approach, even on the U-Boot level, a modification of the
device tree is a prerequisite to have such modular families of boards
supported properly.

Therefore, we add an option to make the U-Boot device tree (the actual
copy later used by the driver model) writeable, and add a callback
method that allows boards to modify the device tree at an early stage,
at which, hopefully, also the application of device tree overlays will
be possible.

spl: Setup default value for OF_LIST

2016-05-23T15:50:21+00:00

OF_LIST can't remain empty that's why setup it up to default DTB.

If it is empty u-boot.img is created without FDT partition:
For example:
  ./tools/mkimage -f auto -A arm -T firmware -C none -O u-boot -a
0x8000000 -e 0 -n "U-Boot 2016.05-rc3 ..." -E -b  -d u-boot-nodtb.bin u-boot.img
Can't set 'timestamp' property for '' node (FDT_ERR_NOSPACE)
FIT description: Firmware image with one or more FDT blobs
Created:         Wed May  4 15:02:52 2016
 Image 0 (firmware@1)
  Description:  U-Boot 2016.05-rc3-00080-gff2e12ae22a8-dirty for zynqmp
board
  Created:      Wed May  4 15:02:52 2016
  Type:         Firmware

  Architecture: ARM
  Load Address: 0x08000000
 Default Configuration: 'conf@1'

And then image like this doesn't contain description and link to FDT and
can't boot.

spl: Add a way to specify a list of device trees to include

2016-03-14T23:18:31+00:00

When building a FIT, more than one device tree can be included. The board
can select (at run-time) the one that it wants.

Add a Kconfig option to allow the list of devices trees (supported by the
board) to be specified.

When using SPL_LOAD_FIT, build u-boot.img in FIT format instead of the
legacy image format. Include all the listed device tree files in this FIT.

dts: keep clock-names and clocks in SPL DTB if SPL_CLK is enabled

2016-02-25T04:06:19+00:00

These two properties are necessary for SPL to get clocks from DT.

Note:
For now, only clock look-up by index is supported (clk_get_by_index()
function), so "clock-names" is never parsed in U-Boot.  However, we
may want to support something like clk_get_by_name() in the future,
so let's keep "clock-names" as well as "clocks".

Revert "devicetree: use wildcard to clean arch subdir"

This reverts commit 67871a595873930a0a536b1685e5caac53766701.

Since that commit, out-of-tree cleaning emits lots of warnings.

devicetree: use wildcard to clean arch subdir

Use wildcard to clean arch subdirectories, as it is cleaner than
listing all the arch which builds dtb.
