This adjusts the point at which certain APIs will switch from

using a stack allocated buffer to a dynamically allocated buffer.
|
|

You shouldn't need to change this unless you really need to
|
|
optimize either stack space or performance. Change this carefully
|
|
since setting an incorrect value could cause stack corruption.

This driver is for PCH (Platform Controller Hub) GPIO of Intel Topcliff,
|
|
which is an IOH (Input/Output Hub) for x86 embedded processor.
|
|
This driver can access PCH GPIO device.
|
|
|
|
This driver also can be used for LAPIS Semiconductor IOH (Input/
|
|
Output Hub), ML7223 and ML7831.
|
|
ML7223 IOH is for MP (Media Phone) use.
|
|
ML7831 IOH is for general purpose use.
|
|
ML7223/ML7831 is companion chip for Intel Atom E6xx series.
|
|
ML7223/ML7831 is completely compatible for Intel EG20T PCH.

bus. For example the Mox module with SFP cage needs this driver
|
|
so that phylink can use corresponding GPIOs.
