2022-01-09dt-bindings: vendor-prefixes: Add SunplusQin Jian1-0/+2

(http://www.sunplus.com) Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Qin Jian <qinjian@cqplus1.com> Signed-off-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/2e74a1339a5ea54d92fdc4d1998a2b169e23b82b.1640154492.git.qinjian@cqplus1.com
2022-01-08of/fdt: Don't worry about non-memory region overlap for no-mapStephen Boyd1-2/+4
In commit 8a5a75e5e9e5 ("of/fdt: Make sure no-map does not remove already reserved regions") we returned -EBUSY when trying to mark regions as no-map when they intersect with reserved memory. The goal was to find bad no-map reserved memory DT nodes that would unmap the kernel text/data sections. The problem is the reserved memory check will still trigger if the DT has a /memreserve/ that completely subsumes the no-map memory carveouts in the reserved memory node _and_ that region is also not part of the memory reg property. For example in sc7180.dtsi we have the following reserved-memory and memory node: memory@80000000 { /* We expect the bootloader to fill in the size */ reg = <0 0x80000000 0 0>; }; smem_mem: memory@80900000 { reg = <0x0 0x80900000 0x0 0x200000>; no-map; }; and the memreserve filled in by the bootloader is /memreserve/ 0x80800000 0x400000; while the /memory node is transformed into memory@80000000 { /* The bootloader fills in the size, and adds another region */ reg = <0 0x80000000 0 0x00800000>, <0 0x80c00000 0 0x7f200000>; }; The smem region is doubly reserved via /memreserve/ and by not being part of the /memory reg property. This leads to the following warning printed at boot. OF: fdt: Reserved memory: failed to reserve memory for node 'memory@80900000': base 0x0000000080900000, size 2 MiB Otherwise nothing really goes wrong because the smem region is not going to be mapped by the kernel's direct linear mapping given that it isn't part of the memory node. Therefore, let's only consider this to be a problem if we're trying to mark a region as no-map and it is actually memory that we're intending to keep out of the kernel's direct mapping but it's already been reserved.

2022-01-08of: base: Improve argument length mismatch errorBaruch Siach1-3/+8
The cells_name field of of_phandle_iterator might be NULL. Use the phandle name instead. With this change instead of: OF: /soc/pinctrl@1000000: (null) = 3 found 2 We get: OF: /soc/pinctrl@1000000: phandle pinctrl@1000000 needs 3, found 2 Which is a more helpful messages making DT debugging easier. In this particular example the phandle name looks like duplicate of the same node name. But note that the first node is the parent node (it->parent), while the second is the phandle target (it->node). They happen to be the same in the case that triggered this improvement.

The cell_count field of of_phandle_iterator is the number of cells we expect in the phandle arguments list when cells_name is missing. The error message should show the number of cells we actually see.

2022-01-04of: unittest: re-implement overlay trackingFrank Rowand1-61/+49
Some overlays are tracked when they are applied. The tracked overlays are later removed after the overlay tests are completed. The old implementation makes assumptions about the expected values for overlay changeset id created by the overlay apply which result in fragile code. The new code removes the assumptions. A symptom that exposes a problem with the tracking code is a warning "UBSAN: shift-out-of-bounds in drivers/of/unittest.c:1933:36", Kernel Version: 5.15-rc7, PPC-64, Talos II. This results from variable "id" value of -1 in the final line of of_unittest_untrack_overlay().
