Linus Torvalds 5647ac0ad4 Removal of GENERIC_GPIO for v3.10 
GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
 cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
 possible to do so which has been causing confusion and breakage. This
 branch does the work to completely eliminate GENERIC_GPIO.
 
 However, it is not trivial to just create a branch to remove it. Over
 the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
 added to linux-next that conflicts with this branch. The following must
 be done to resolve the conflicts when merging this branch into mainline:
 
 * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
   replaced with CONFIG_GPIOLIB
 * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
   documentation.
 * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
 * definitions of the option in architecture Kconfig code should be deleted.
 
 Stephen has 3 merge fixup patches[1] that do the above. They are currently
 applicable on mainline as of May 2nd.

Support for running natively on the hardware, i.e. without
a hypervisor. This option is not user-selectable but should
be selected by all platforms that need it.
config PPC_OF_BOOT_TRAMPOLINE
bool "Support booting from Open Firmware or yaboot"

help
Support from booting from Open Firmware or yaboot using an

Select this opton if your platform supports SMP and your

This option enables a MPIC driver workaround for some chips

to not read back properly. It is safe to use on other chips as
well, but enabling it uses about 8KB of memory to keep copies
of the register contents in software.

config PPC601_SYNC_FIX
bool "Workarounds for PPC601 bugs"
depends on 6xx && PPC_PMAC
help
Some versions of the PPC601 (the first PowerPC chip) have bugs which
mean that extra synchronization instructions are required near
certain instructions, typically those that make major changes to the
CPU state. These extra instructions reduce performance slightly.
If you say N here, these extra instructions will not be included,
resulting in a kernel which will run faster but may not run at all
on some systems with the PPC601 chip.
If in doubt, say Y here.
config TAU
bool "On-chip CPU temperature sensor support"
depends on 6xx
help
G3 and G4 processors have an on-chip temperature sensor called the
'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
temperature within 2-4 degrees Celsius. This option shows the current
on-die temperature in /proc/cpuinfo if the cpu supports it.
Unfortunately, on some chip revisions, this sensor is very inaccurate
and in many cases, does not work at all, so don't assume the cpu
temp is actually what /proc/cpuinfo says it is.
config TAU_INT
bool "Interrupt driven TAU driver (DANGEROUS)"
depends on TAU
---help---
The TAU supports an interrupt driven mode which causes an interrupt
whenever the temperature goes out of range. This is the fastest way
to get notified the temp has exceeded a range. With this option off,
a timer is used to re-check the temperature periodically.
However, on some cpus it appears that the TAU interrupt hardware
is buggy and can cause a situation which would lead unexplained hard
lockups.
Unless you are extending the TAU driver, or enjoy kernel/hardware
debugging, leave this option off.
config TAU_AVERAGE
bool "Average high and low temp"
depends on TAU
---help---
The TAU hardware can compare the temperature to an upper and lower
bound. The default behavior is to show both the upper and lower
bound in /proc/cpuinfo. If the range is large, the temperature is
either changing a lot, or the TAU hardware is broken (likely on some
G4's). If the range is small (around 4 degrees), the temperature is
relatively stable. If you say Y here, a single temperature value,
halfway between the upper and lower bounds, will be reported in
/proc/cpuinfo.
If in doubt, say N here.
config QUICC_ENGINE
bool "Freescale QUICC Engine (QE) Support"
depends on FSL_SOC && PPC32
select PPC_LIB_RHEAP
select CRC32
help
The QUICC Engine (QE) is a new generation of communications
coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
Selecting this option means that you wish to build a kernel
for a machine with a QE coprocessor.
config QE_GPIO
bool "QE GPIO support"
depends on QUICC_ENGINE
select ARCH_REQUIRE_GPIOLIB
help
Say Y here if you're going to use hardware that connects to the
QE GPIOs.
config CPM2
bool "Enable support for the CPM2 (Communications Processor Module)"
depends on (FSL_SOC_BOOKE && PPC32) || 8260
select CPM
select PPC_LIB_RHEAP
select PPC_PCI_CHOICE
select ARCH_REQUIRE_GPIOLIB
help
The CPM2 (Communications Processor Module) is a coprocessor on
embedded CPUs made by Freescale. Selecting this option means that
you wish to build a kernel for a machine with a CPM2 coprocessor
on it (826x, 827x, 8560).
config AXON_RAM
tristate "Axon DDR2 memory device driver"
depends on PPC_IBM_CELL_BLADE && BLOCK

help
It registers one block device per Axon's DDR2 memory bank found
on a system. Block devices are called axonram?, their major and
minor numbers are available in /proc/devices, /proc/partitions or
in /sys/block/axonram?/dev.
config FSL_ULI1575
bool
default n

help
Supports for the ULI1575 PCIe south bridge that exists on some
Freescale reference boards. The boards all use the ULI in pretty
much the same way.
config CPM
bool
config OF_RTC
bool
help
Uses information from the OF or flattened device tree to instantiate
platform devices for direct mapped RTC chips like the DS1742 or DS1743.
config SIMPLE_GPIO

depends on PPC
select ARCH_REQUIRE_GPIOLIB
help
Say Y here to support simple, memory-mapped GPIO controllers.
These are usually BCSRs used to control board's switches, LEDs,
chip-selects, Ethernet/USB PHY's power and various other small
on-board peripherals.
config MCU_MPC8349EMITX
bool "MPC8349E-mITX MCU driver"
depends on I2C=y && PPC_83xx
select ARCH_REQUIRE_GPIOLIB
help
Say Y here to enable soft power-off functionality on the Freescale
boards with the MPC8349E-mITX-compatible MCU chips. This driver will
also register MCU GPIOs with the generic GPIO API, so you'll able
to use MCU pins as GPIOs.
