[PATCH v6 0/4] add syscon driver based on regmap for general registers access

This patch series mainly adds an syscon driver which is used to access
general system controller registers like FSL IOMUXC GPR and ANATOP,
after that, we convert all the exist private access general registers code to use
standard API from regmap to access registers.
Finally we remove the old mfd anatop driver which is only for anatop register
access.

The patch series is based on linus's tree 3.6-rc4 since commit 5b716ac.

ChangeLog v5->v6:
 * put node after call syscon_node_to_regmap in anatop regulator driver
 * using dev instead of &pdev->dev in syscon probe
ChangeLog v4->v5:
 * change syscon driver depends on OF
 * do not call of_node_put in syscon_node_to_regmap
 * renamed: include/linux/fsl/imx6q-iomuxc-gpr.h ->
	    include/linux/mfd/syscon/imx6q-iomuxc-gpr.h
ChangeLog v3->v4:
Only '[PATCH v4 1/7] mfd: add syscon driver based on regmap' is changed.

Dong Aisheng (4):
  mfd: add syscon driver based on regmap
  ARM: imx6q: add iomuxc gpr support into syscon
  regulator: anatop-regulator: convert to use syscon to access anatop
    register
  mfd: anatop-mfd: remove anatop driver
