We set the pin configuration for the jz4740-nand, jz4740-mmc,

This will permit those drivers to be cleaned out of the custom GPIO code
that they currently use.

This is the v2 of my ingenic pinctrl patch series.
Huge changes in there, the pinctrl driver was completely rewritten, and the

It now uses the generic functions to handle pin groups, as well as generic
devicetree bindings.

* Return an error code without storing it in an intermediate variable.
* Delete the local variable "r" and the jump label "out" which became
unnecessary with this refactoring.

The script "checkpatch.pl" pointed information out like the following.
Comparison to NULL could be written …
Thus fix affected source code places.

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

Summary of this patchset in v1 (actually v2 as the v1 got posted 2 years
ago): https://lkml.org/lkml/2016/11/17/583
Changes in this version:
* Rebase against latest cputime changes (vtime accumulation and accounting
delayed on tick and context switch)
* Fix leaking cputime remainder on s390
*
It's a leftover from removed code.

Use the new nsec based cputime accessors as part of the whole cputime
conversion from cputime_t to nsecs.

Kernel cpu stats are stored in cputime_t which is an architecture
defined type, and hence a bit opaque and requiring accessors and mutators
for any operation.
Converting them to nsecs simplifies the code and is one step toward
the removal of cputime_t in the core code.

cputime_t is being obsolete and replaced by nsecs units in order to make
internal timestamps less opaque and more granular.

conversion from cputime_t to nsecs.
Also convert itimers to use nsec based internal counters. This simplifies
it and remove the whole game with error/inc_error which served to deal
with cputime_t random granularity.
