Hi
Hi Thomas,
With the updated patch and the modified sensors-detect I have been
able to probe all ports and have not encountered the power issue
again. If no further issues are identified I will seperate the patch
into stages and submit for review.
I confirm that your patch works well on my
A quick hack to verify that the fix works as intended...

When the system is under heavy load, there can be a significant delay
between the getscl() and time_after() calls inside sclhi(). That delay
may cause the time_after() check to trigger after SCL has gone high,
causing sclhi() to return -ETIMEDOUT.
To fix the problem, double check that SCL is

Hi,
This series (against mfd-2.6/for-next) changes the mc13xxx driver to use
regmap and adds I2C support. It generally goes about this the same way as
the previous 2 versions, but now uses regmap.
I am unable to test SPI functionality, but the I2C stuff works. It would be
great if someone
This adds support for devices with 7 address bits and 25 data bits.
The initial intended user for this are the mc13xxx mfds in spi mode.
(The 25th data bit is actually a dummy bit)

All spi specific code is moved into a new module. The mc13xxx struct
moves to a new local include file by necessity.
A new config choice selects the SPI bus type support and by default is
value of SPI_MASTER to remain compatible with existing configs.

This change converts the mc13xxx core to use regmap rather than direct
spi r/w.
The spidev member of mc13xxx struct becomes redundant and is removed.
Extra debugging aids are added to mc13xxx_reg_rmw.
Mutex init is moved to before regmap init.

This patch abstracts the bus specific operations from the driver core.
Generic init and cleanup is consolidated into mc13xxx_common_*.
spi specific functions are renamed to reflect such.
(The irq member of the mc13xxx struct is no longer redundant, it's used
to store the irq for cleanup time).
Adds support for mc13xxx family ICs connected via i2c.

mc13783 does not have i2c interface.
