Subject: [PATCH] nvmem: qfprom: Mark core clk as optional
|
||||||
|
|
||||||
|
On some platforms like sc7280 on non-ChromeOS devices the core clock
|
||||||
|
cannot be touched by Linux so we cannot provide it. Mark it as optional
|
||||||
|
as accessing qfprom for reading works without it but we still prohibit
|
||||||
|
writing if we cannot provide the clock.

Subject: [PATCH] nvmem: add explicit config option to read old syntax fixed OF
|
||||||
|
cells
|
||||||
|
MIME-Version: 1.0
|
||||||
|
Content-Type: text/plain; charset=UTF-8

|
||||||
|
|
||||||
|
Binding for fixed NVMEM cells defined directly as NVMEM device subnodes
|
||||||
|
has been deprecated. It has been replaced by the "fixed-layout" NVMEM
|
||||||
|
layout binding.
|
||||||
|
|
||||||
|
New syntax is meant to be clearer and should help avoiding imprecise
|
||||||
|
bindings.
|
||||||
|
|
||||||
|
NVMEM subsystem already supports the new binding. It should be a good
|
||||||
|
idea to limit support for old syntax to existing drivers that actually
|
||||||
|
support & use it (we can't break backward compatibility!). That way we
|
||||||
|
additionally encourage new bindings & drivers to ignore deprecated
|
||||||
|
binding.
|
||||||
|
|
||||||
|
It wasn't clear (to me) if rtc and w1 code actually uses old syntax
|
||||||
|
fixed cells. I enabled them to don't risk any breakage.

Use preferred device_get_match_data() instead of of_match_device() to

get the driver match data. With this, adjust the includes to explicitly

include the correct headers.

Subject: [PATCH] Revert "nvmem: add new config option"
|
||||||
|
MIME-Version: 1.0
|
||||||
|
Content-Type: text/plain; charset=UTF-8
|
||||||

||||||
|
This reverts commit 517f14d9cf3533d5ab4fded195ab6f80a92e378f.
|
||||||
|
|
||||||
|
Config option "no_of_node" is no longer needed since adding a more
|
||||||
|
explicit and targeted option "add_legacy_fixed_of_cells".
|
||||||
|
|
||||||
|
That "no_of_node" config option was needed *earlier* to help mtd's case.
|
||||||
|
|
||||||
|
DT nodes of MTD partitions (that are also NVMEM devices) may contain
|
||||||
|
subnodes. Those SHOULD NOT be treated as NVMEM fixed cells.
|
||||||
|
|
||||||
|
To prevent NVMEM core code from parsing subnodes a "no_of_node" option
|
||||||
|
was added (and set to true in mtd) to make for_each_child_of_node() in
|
||||||
|
NVMEM a no-op. That was a bit hacky because it was messing with
|
||||||
|
"of_node" pointer to achieve some side-effect.
|
||||||
|
|
||||||
|
With the introduction of "add_legacy_fixed_of_cells" config option
|
||||||
|
things got more explicit. MTD subsystem simply tells NVMEM when to look
|
||||||
|
for fixed cells and there is no need to hack "of_node" pointer anymore.
