Hi Marc,

I am running linux-next 3.4.0-next-20120521 on a mx31pdk board that
has a mc13783 PMIC connected to SPI.

I am getting a kernel hang after 'regmap_read' inside mc13xxx_reg_read function.

Does it work fine for you on your mx35 board? Am I missing any recent patch?

My understanding is that you have only tested i2c connection with this
PMIC. Is this correct?

Any ideas on how to solve this issue is appreciated.

Regards,

Fabio Estevam
