88PM8606 and 88PM8607 are two discrete chips used for power management.
Hardware designer can use them together or only one of them according to
requirement.
There's some logic tightly linked between these two chips. For example, USB
charger driver needs to access both chips by I2C interface.
Now share one driver to these two devices. Only one I2C client is identified
in platform init data. If another chip is also used, user should mark it in
companion_addr field of platform init data. Then driver could create another
I2C client for the companion chip.
All I2C operations are accessed by 860x-i2c driver. In order to support both
I2C client address, the read/write API is changed in below.
reg_read(client, offset)
reg_write(client, offset, data)
The benefit is that client drivers only need one kind of read/write API. I2C
and MFD driver can be shared in both 8606 and 8607.
Since API is changed, update API in 8607 regulator driver.

Unlike the wm8350-custom code genirq nests enable and disable calls
so we can't just unconditionally mask or unmask the interrupt,
we need to remember the state we set and only mask or unmask when
there is a real change.

The structure t7l66xb should not be freed before the subsequent references
to its fields in the arguments to clk_put. Furthermore, this structure is
allocated near the beginning of the function, and a goto to the label
err_noirq appears after a successful allocation, so it would seem that the
kfree should be moved down below this label.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

This reverts commit a069c266ae.
It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.
So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in. It's not all _that_ big, after all, and the inconvenience
isn't worth it.

These two functions provide support for mapping and
unmapping physical addresses to io virtual addresses. The
difference to the iommu_(un)map_range() is that the new
functions take a gfp_order parameter instead of a size. This
allows the IOMMU backend implementations to detect easier if
a given range can be mapped by larger page sizes.
These new functions should replace the old ones in the long
term.
