The PPL controller provides the 3 main clocks of the SoC: CPU, DDR and AHB.
Required Properties:
-- compatible: has to be "qca,<soctype>-cpu-intc" and one of the following
+- compatible: has to be "qca,<soctype>-pll" and one of the following
fallbacks:
- "qca,ar7100-pll"
- "qca,ar7240-pll"
Example:
- memory-controller@18050000 {
- compatible = "qca,ar9132-ppl", "qca,ar9130-pll";
+ pll-controller@18050000 {
+ compatible = "qca,ar9132-pll", "qca,ar9130-pll";
reg = <0x18050000 0x20>;

which the timestamp reverts to 1970, i.e. moves backwards in time.
Currently, cramfs must be written and read with architectures of the

+same endianness, and can be read only by kernels with PAGE_SIZE
== 4096. At least the latter of these is a bug, but it hasn't been
decided what the best fix is. For the moment if you have larger pages
you can just change the #define in mkcramfs.c, so long as you don't
default is half of your physical RAM without swap. If you
oversize your tmpfs instances the machine will deadlock
since the OOM handler will not be able to free that memory.
-nr_blocks: The same as size, but in blocks of PAGE_CACHE_SIZE.
+nr_blocks: The same as size, but in blocks of PAGE_SIZE.
nr_inodes: The maximum number of inodes for this instance. The default
is half of the number of your physical RAM pages, or (on a
machine with highmem) the number of lowmem RAM pages,
from the address space. This generally corresponds to either a
truncation, punch hole or a complete invalidation of the address
space (in the latter case 'offset' will always be 0 and 'length'
- will be PAGE_CACHE_SIZE). Any private data associated with the page
+ will be PAGE_SIZE). Any private data associated with the page
should be updated to reflect this truncation. If offset is 0 and
- length is PAGE_CACHE_SIZE, then the private data should be released,
+ length is PAGE_SIZE, then the private data should be released,
because the page must be able to be completely discarded. This may
be done by calling the ->releasepage function, but in this case the
release MUST succeed.
