dm: core: Fix dm_extended_scan_fdt()

2019-05-21T23:33:23Z

This function takes an argument, blob, but never uses it, instead uses gd->fdt_blob directly. Fixes: e81c98649b7a ("dm: core: add clocks node scan") Reported-by: AKASHI Takahiro Signed-off-by: Patrice Chotard Reviewed-by: Bin Meng

dm: core: Change platform specific translation-offset handling

2019-04-24T02:26:43Z

Testing has shown that the current DM implementation of a platform / board specific translation offset, as its needed for the SPL on MVEBU platforms is buggy. The translation offset is confingured too late, after the driver bind functions are run. This may result in incorrect address translations. With the current implementation its not possible to configure the offset earlier, as the DM code has not run at all. This patch now removed the set_/get_translation_offset() calls and moves the translation offset into the GD variable translation_offset. This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled. This option is enabled only for MVEBU on ARM32 platforms, where its currenty needed and configured in the SPL.

drivers: core: nullify gd->dm_root after dm_uninit()

2018-12-10T06:23:45Z

To reset the DM after a new dtb is loaded, we need to call dm_uninit() and then dm_init(). This fails however because gd->dm_root is not nullified by dm_uninit(). Fixing it by setting gd->dm_root in dm_uninit(). Signed-off-by: Jean-Jacques Hiblot Reviewed-by: Simon Glass Reviewed-by: Heiko Schocher

dm: core: Mirror the chosen node parse logic in the livetree scanning

2018-11-14T17:16:27Z

Commit f2006808f099: ("dm: core: parse chosen node") added a logic to parse the chosen node during dm_scan_fdt_node(), but unfortunately it missed adding the same logic in dm_scan_fdt_live(). This mirrors the logic in the livetree version. The weird thing is that commit f2006808f099 did update the test case to test such logic, but even if I reset to that commit, the test case still fails, and I have no idea how it could pass. With this fix, the following 2 test cases now pass: Test: dm_test_bus_children: bus.c test/dm/bus.c:112, dm_test_bus_children(): num_devices == list_count_items(&uc->dev_head): Expected 7, got 6 Test: dm_test_fdt: test-fdt.c test/dm/test-fdt.c:184, dm_test_fdt(): num_devices == list_count_items(&uc->dev_head): Expected 7, got 6 Fixes: f2006808f099 ("dm: core: parse chosen node") Signed-off-by: Bin Meng Reviewed-by: Simon Glass

dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()

2018-11-14T17:16:27Z

Currently the comments of several APIs (eg: dm_init_and_scan()) say: @pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC flag. If false bind all drivers. The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt documents the same that both device tree properties and driver flag are supported. However the implementation only checks these special device tree properties without checking the driver flag at all. This updates lists_bind_fdt() to consider both scenarios.

dm: core: Scan "/firmware" node by default

2018-09-18T14:12:21Z

All Linux firmware drivers are put under "/firmware" node and it has support to populate "/firmware" node by default. u-boot and Linux can share same DTB. In this case, driver probe for devices under "/firmware" will not be invoked as "/firmware" does not have its own "compatible" property. This patch scans "/firmware" node by default like "/clocks".

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini
