You're right, i'm afra
code paths have a slight difference.
The path1 does not request the mem region, the main reason of that is we meet
some devices register ranges used as syscon maybe overlapped with
other exist drivers.
e.g imx6q.dtsi
The gpr is a few registers contained in iomuxc.
gpr: iomuxc-gpr@020e {

If the platform can convert to dt, then we do not have such issue.
The question is do we allow the existing non-dt platforms to use it
before converting?

few whitespace warnings when applying your patch and

Add regmap based syscon driver.
This is usually used for access misc bits in registers which does not belong
to a specific module, for example, IMX IOMUXC GPR and ANATOP.
With this driver, client can use generic regmap API to access registers
which are registered into syscon
anatop driver which is only for anatop register
access.
The patch series is based on linus's tree 3.6-rc3 since commit 9160338.
Dong Aisheng (7):
mfd: add syscon driver based on regmap
ARM: imx6q: add iomuxc gpr support into syscon
ARM: imx6q: add anatop support into syscon
regu
From: Dong Aisheng
There're a few anatop registers need to be accessed by different modules.
Add anatop registers into syscon support for easy access.

Since mfd anatop driver will be deleted later, we change to populate the

The anatop registers are accessed via syscon now, no one will use
mfd anatop driver anymore, remove it.

Hi Thomas,
Thanks for the review firstly.
