anatop pu regulator enable issue

[hailiu]

hello community members.

I am debugging a booting problem with customer board using imx6solo processor. I use pfuze100 SW1 as supply for VDDSOC and VDDPU, SW2 as supply for ADDARM. At first, I did not modified the vddpu and vddsoc supply in the dts file, the pfuze100 was not registered, the only problem is that galcore driver is not loaded, I can logging as a root user. then I modified the dts file to the right supplies for vddsoc and vddpu, and the pfuze100 is registered, but when the system is in the process of doing deferred task, and enable the pu domain regulator, which is anatop register with offset 0x140, the system crash.  it crashes when the function:

regmap_mmio_write32le(struct regmap_mmio_context *ctx, unsigned int reg,unsigned int val)

in regmap.c is executed. this function is only one line: writel(val, ctx->regs + reg);

I checked the val, ctx->reg and reg value, all are correct. ctx->regs=0xF42C8000, reg=0x140. The funny things are that if I add a line to print out some thing in the file drivers/regulator/core.c in the function:

_regulator_do_enable(struct regulator_dev *rdev)

after the line:

ret = rdev->desc->ops->enable(rdev);

The system can boot up, galcore driver can be loaded, and I can login as a root user, but I see one or two times that after Started Weston, a Wayland mpositor, as a system service, when write anatop register 0x140, system stuck. Is it something related with timing of register writing or a stack overflow?

the following are two copies, the first one does not has the code added to core.c, and second is the one with code added to core.c but crashed after started Weston successfully.
