These patches add support to configure on-chip SRAM via device-tree
node or platform data and to obtain the resulting genalloc pool from
the struct device pointer or a phandle pointing at the device tree node.
This allows drivers to allocate SRAM with the genalloc API without
hard-coding the
This driver requests and remaps a memory region as configured in the
device tree. It serves memory from this region via the genalloc API.
It optionally enables the SRAM clock.
Other drivers can retrieve the genalloc pool from a phandle pointing
to this drivers' device node in the device tree.

Even though nlmclnt_reclaim() is only one call into the stack frame,
928 bytes on the stack seems like a lot. Recode to dynamically
allocate the request structure once from within the reclaimer task,
then pass this pointer into nlmclnt_reclaim() for reuse on
subsequent calls.

During the development of this driver an in-house register
documentation was used. The last weeks some integration tests
were done and this problem was found. It turned out that
the released register documentation is wrong.
The fix is very simple: shift all masks by one.

Using readl() to read the magic value and then memcmp() to check it
fails on BE, as bytes will be the other way around (by virtue of
the registers to follow the endianess of the guest).
Fix it by encoding the magic as an integer instead of a string.

This patch works but it's nasty to re-intialize "reg" inside both

That means we would also delete the ininitialization from the if

The return value from of_get_named_gpio is -ENOENT when the given index
matches a hole in the "cs-gpios" property phandle list. However, the
default value of cs_gpio in struct spi_device and entries of cs_gpios in
struct spi_master is -EINVAL, which is documented to indicate that a

Most of the MFD module have the GPIO and gpio interrupt is

is no specific mask enable/disable registers for GPIO submodules.

Ignore the mask register write if mask_base is not provided by
regmap irq client. This is useful when regmap irq framework is
used for the MFD's gpio interrupt support. Typically, gpio has
two registers related to interrupt, one is for setting interrupt

This changeset is aimed at fixing a few different but related
problems in the ACPI hotplug infrastructure.
First of all, since notify handlers may be run in parallel with
acpi_bus_scan(), acpi_bus_trim() and acpi_bus_hot_remove_device()
and some of them are installed for
