+config ANDROID
+ bool "Android Drivers"
+ ---help---
+ Enable support for various drivers needed on the Android platform
+
+if ANDROID
+
+config ANDROID_BINDER_IPC
+ bool "Android Binder IPC Driver"
+ depends on MMU
+ default n
+ ---help---
+ Binder is used in Android for both communication between processes,
+ and remote method invocation.
+
+ This means one Android process can call a method/routine in another
+ Android process, using Binder to identify, invoke and pass arguments
+ between said processes.
+
+config ANDROID_BINDER_IPC_32BIT
+ bool
+ depends on !64BIT && ANDROID_BINDER_IPC
+ default y
+ ---help---
+ The Binder API has been changed to support both 32 and 64bit
+ applications in a mixed environment.
+
+ Enable this to support an old 32-bit Android user-space (v4.4 and
+ earlier).
+
+ Note that enabling this will break newer Android user-space.
+
+config ASHMEM
+ bool "Enable the Anonymous Shared Memory Subsystem"
+ default n
+ depends on SHMEM
+ ---help---
+ The ashmem subsystem is a new shared memory allocator, similar to
+ POSIX SHM but with different behavior and sporting a simpler
+ file-based API.
+
+ It is, in theory, a good memory allocator for low-memory devices,
+ because it can discard shared memory units when under memory pressure.
+
+config ANDROID_LOGGER
+ tristate "Android log driver"
+ default n
+ ---help---
+ This adds support for system-wide logging using four log buffers.
+
+ These are:
+
+ 1: main
+ 2: events
+ 3: radio
+ 4: system
+
+ Log reading and writing is performed via normal Linux reads and
+ optimized writes. This optimization avoids logging having too
+ much overhead in the system.
+
+config ANDROID_TIMED_OUTPUT
+ bool "Timed output class driver"
+ default y
+
+config ANDROID_TIMED_GPIO
+ tristate "Android timed gpio driver"
+ depends on GPIOLIB && ANDROID_TIMED_OUTPUT
+ default n
+
+config ANDROID_LOW_MEMORY_KILLER
+ bool "Android Low Memory Killer"
+ ---help---
+ Registers processes to be killed when memory is low
+
+config ANDROID_INTF_ALARM_DEV
+ bool "Android alarm driver"
+ depends on RTC_CLASS
+ default n
+ ---help---
+ Provides non-wakeup and rtc backed wakeup alarms based on rtc or
+ elapsed realtime, and a non-wakeup alarm on the monotonic clock.
+ Also exports the alarm interface to user-space.
+
+config SYNC
+ bool "Synchronization framework"
+ default n
+ select ANON_INODES
+ ---help---
+ This option enables the framework for synchronization between multiple
+ drivers. Sync implementations can take advantage of hardware
+ synchronization built into devices like GPUs.
+
+config SW_SYNC
+ bool "Software synchronization objects"
+ default n
+ depends on SYNC
+ ---help---
+ A sync object driver that uses a 32bit counter to coordinate
+ syncrhronization. Useful when there is no hardware primitive backing
+ the synchronization.
+
+config SW_SYNC_USER
+ bool "Userspace API for SW_SYNC"
+ default n
+ depends on SW_SYNC
+ ---help---
+ Provides a user space API to the sw sync object.
+ *WARNING* improper use of this can result in deadlocking kernel
+ drivers from userspace.
