* Decrease codes of pinctrl-rockchip.c from 4,000 lines to 2000 by
separating soc data to a new file.
* Move rockchip pinctrl related struct definations to a head file.
* Keep legency pinctrl-rockchip.c under driver/pinctrl but not to
compile it, conveniently for reviewers.

* Decrease codes of pinctrl-rockchip.c from 4,000 lines to 2000 by
separating soc data to a new file.
* Move rockchip pinctrl related struct definations to a head file.
* Keep legency pinctrl-rockchip.c under driver/pinctrl but not to
compile it, conveniently for reviewers.
Signed-off-by: Jianqun Xu <[email protected]>

This patch looks good, two things are missing:
- Review from Heiko
- A change to MAINTAINERS so that the file pattern still
matches
Should someone from Rockchip also sign up as comaintainer
for this driver by the way? (Though the people at Rockchip
posting patches for this seem to change a bit.)
Yours,
Linus Walleij

The kernel Image size is keep growing, this patch can help reduce the
size of
kernel image for one SoC, and this is what we have done in U-Boot mainline.
And for distribution kernel who need to cover all the SoCs with one
kernel image,
need to update the defconfig.
The patch looks good to me,

The pinctrl-rockchip driver grows larger by adding support for
each new SoC, that make the kernel Image size too large since
it only under one config named PINCTRL_ROCKCHIP.
This patch split driver in the form of core driver + soc driver,
- pinctrl-rockchip.c defined an platform probe register function
- pinctrl-rkxxxx.c init module by matching compatible name
For rockchip_defconfig, it needs to select all PINCTRL_RKxxxx to
keep same with old driver.
For some special defconfig, it can only select one PINCTRL_RKxxxx.

2.17.1
The pinctrl-rockchip driver grows larger by adding support for
each new SoC, that make the kernel Image size too large since
it only under one config named PINCTRL_ROCKCHIP.
This patch split driver in the form of core driver + soc driver,
- pinctrl-rockchip.c defined an platform probe register function
- pinctrl-rkxxxx.c init module by matching compatible name
For rockchip_defconfig, it needs to select all PINCTRL_RKxxxx to
keep same with old driver.
For some special defconfig, it can only select one PINCTRL_RKxxxx.

changes since v2:
- remove rockchip_pinctrl_remove
- rename rockchip_pinctrl_* to rockchip_pctrl_*
- redule arguments for get_soc_data
- add module author for each new driver files
- add copyright for new driver files
changes since v1:
- add rockchip_pinctrl_remove
- remove unused head files in pinctrl-rockchip.h

Hmm, it looks like you're still leaving behind the old file as entirely
dead code, which doesn't seem particularly good.
FWIW, a nice way to make a change like this easy to review is to have an
initial patch that just moves the existing C file and config/build stuff
to the new subdirectory (use `git format-patch -M ...`), then one or
more further patches on top to split out the individual SoC options.
That way the diffs stay small and reviewers don't have to read the patch
side-by-side with the original file to confirm that the "new" code
really is identical to what was there before.

Do codingstyle for pinctrl-rockchip by spliting driver by SoC types.
Convenienty for reviewing, the first patch only moving
pinctrl-rockchip.c from driver/pinctrl to driver/pinctrl/rockchip/ .

Create a new direcoty "rockchip" under pinctrl for pinctrl-rockchip.
This is base patch which prepares for spliting driver by SoC types.

Why were these patches never applied? Is it my fault?
I don't even have patch 2/2 in my mailbox, possibly it was
too big!
Heiko if you're OK with this change can Jianqun just send a
rebased version?
Yours,

It's not your fault :-)

We agreed to split it into smaller chunks which I think is the 13-patch
series you mentioned elsewhere today. But I guess that fell through
the cracks in my review :-( .
So I guess we should do the current GKI thingy first to get that
module build and after that maybe Jianqun can find the time to rebase
the per-soc split on top of that.
