nvmem: add missing of_node_put() in of_nvmem_cell_get()

2017-09-18T14:12:26+00:00

of_get_next_parent() increments the refcount of the returned node.
It should be put when done.

nvmem: core: return EFBIG on out-of-range write

2017-09-18T14:12:26+00:00

When writing data that exceeds the nvmem size to a nvmem sysfs file
using the sh redirection operator >, the shell hangs, trying to
write the out-of-range bytes endlessly.

Fix the problem by returning EFBIG described in man 2 write.

Similar change was done for binary sysfs files on commit

nvmem: core: remove unneeded NULL check

2017-08-28T15:33:23+00:00

"p" is the list iterator so it can't be NULL.  Static checkers complain
about this unnecessary check because we dereference the list iterator to
get the next item in the list so we'd be in trouble if it really was
NULL.  I have removed the check.

nvmem: core: Add nvmem_cell_read_u32

2017-08-28T15:33:23+00:00

This function does a quick and easy read of an u32 value without any
kind of resource management code on the consumer side.

nvmem: Convert to using %pOF instead of full_name

2017-08-28T15:33:22+00:00

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

nvmem: lpc18xx-eeprom: explicitly request exclusive reset control

2017-08-28T15:33:22+00:00

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

nvmem: rockchip-efuse: amend compatible rk322x-efuse to rk3228-efuse

2017-07-17T14:15:57+00:00

As the comments from Heiko Stuebner  that compatible
should not contain any placeholders, this patch fix it for rk3228 SoC.

Note that this is a fix for v4.13, due to fixing the current non-standard
binding name that should not become part of an official kernel release.

nvmem: core: add locking to nvmem_find_cell

2017-06-09T10:08:27+00:00

Adding entries to nvmem_cells and deleting entries from it is
protected by nvmem_cells_mutex. Therefore this mutex should
also protect iterating over the list.

Call put_device() in nvmem_unregister() to make sure nvmem_release
