+Description:
+
+ As a Kconfig option, individual GPIO signals may be accessed from
+ userspace. GPIOs are only made available to userspace by an explicit
+ "export" operation. If a given GPIO is not claimed for use by
+ kernel code, it may be exported by userspace (and unexported later).
+ Kernel code may export it for complete or partial access.
+
+ GPIOs are identified as they are inside the kernel, using integers in
+ the range 0..INT_MAX. See Documentation/gpio.txt for more information.
+
+ /sys/class/gpio
+ /export ... asks the kernel to export a GPIO to userspace
+ /unexport ... to return a GPIO to the kernel
+ /gpioN ... for each exported GPIO #N
+ /value ... always readable, writes fail for input GPIOs
+ /direction ... r/w as: in, out (default low); write: high, low
+ /gpiochipN ... for each gpiochip; #N is its first GPIO
+ /base ... (r/o) same as N
+ /label ... (r/o) descriptive, not necessarily unique
+ /ngpio ... (r/o) number of GPIOs; numbered N to N + (ngpio - 1)

When a kernel change causes the interface that the kernel exposes to
userspace to change, it is recommended that you send the information or
a patch to the manual pages explaining the change to the manual pages
-maintainer at mtk.manpages@gmail.com.
+maintainer at mtk.manpages@gmail.com, and CC the list
+linux-api@vger.kernel.org.
Here is a list of files that are in the kernel source tree that are
required reading:
19: All new userspace interfaces are documented in Documentation/ABI/.
See Documentation/ABI/README for more information.
+ Patches that change userspace interfaces should be CCed to
+ linux-api@vger.kernel.org.
20: Check that it all passes `make headers_check'.
There is an exception to the above. If hotplug functionality is used
to remove all the CPUs that are currently assigned to a cpuset,
-then the kernel will automatically update the cpus_allowed of all
-tasks attached to CPUs in that cpuset to allow all CPUs. When memory
-hotplug functionality for removing Memory Nodes is available, a
-similar exception is expected to apply there as well. In general,
-the kernel prefers to violate cpuset placement, over starving a task
-that has had all its allowed CPUs or Memory Nodes taken offline. User
-code should reconfigure cpusets to only refer to online CPUs and Memory
-Nodes when using hotplug to add or remove such resources.
+then all the tasks in that cpuset will be moved to the nearest ancestor
+with non-empty cpus. But the moving of some (or all) tasks might fail if
+cpuset is bound with another cgroup subsystem which has some restrictions
+on task attaching. In this failing case, those tasks will stay
+in the original cpuset, and the kernel will automatically update
+their cpus_allowed to allow all online CPUs. When memory hotplug
+functionality for removing Memory Nodes is available, a similar exception
+is expected to apply there as well. In general, the kernel prefers to
+violate cpuset placement, over starving a task that has had all
+its allowed CPUs or Memory Nodes taken offline.
There is a second exception to the above. GFP_ATOMIC requests are
kernel internal allocations that must be satisfied, immediately.

+---------------------------
+
+What: ide-scsi (BLK_DEV_IDESCSI)
+When: 2.6.29
+Why: The 2.6 kernel supports direct writing to ide CD drives, which
+ eliminates the need for ide-scsi. The new method is more
+ efficient in every way.

+usb_unlink_anchored_urbs()
+--------------------------
+
+This function unlinks all URBs associated with an anchor. The URBs
+are processed in the reverse temporal order they were submitted.
+This is similar to usb_kill_anchored_urbs(), but it will not sleep.
+Therefore no guarantee is made that the URBs have been unlinked when

-------------------------------
This function waits for all URBs associated with an anchor to finish

- SMTC pseudo-interrupts between TCs are deferred and queued

- SMTC prototypes, these queued IPIs were serviced on return

+ * Variant clock event timer support for SMTC on MIPS 34K, 1004K
+ * or other MIPS MT cores.
+ *
+ * Notes on SMTC Support:
+ *
+ * SMTC has multiple microthread TCs pretending to be Linux CPUs.
+ * But there's only one Count/Compare pair per VPE, and Compare
+ * interrupts are taken opportunisitically by available TCs
+ * bound to the VPE with the Count register. The new timer
+ * framework provides for global broadcasts, but we really
+ * want VPE-level multicasts for best behavior. So instead
+ * of invoking the high-level clock-event broadcast code,
+ * this version of SMTC support uses the historical SMTC
+ * multicast mechanisms "under the hood", appearing to the
+ * generic clock layer as if the interrupts are per-CPU.
+ *
+ * The approach taken here is to maintain a set of NR_CPUS
+ * virtual timers, and track which "CPU" needs to be alerted
+ * at each event.
+ *
+ * It's unlikely that we'll see a MIPS MT core with more than
+ * 2 VPEs, but we *know* that we won't need to handle more
+ * VPEs than we have "CPUs". So NCPUs arrays of NCPUs elements
+ * is always going to be overkill, but always going to be enough.

+ This is the generic IDE driver. This driver attaches to the
+ fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
+ so on). Please note that if this driver is built into the
+ kernel or loaded before other ATA (IDE or libata) drivers
+ and the controller is located at legacy ports, this driver
+ may grab those ports and thus can prevent the controller
+ specific driver from attaching.
+
+ Also, currently, IDE generic doesn't allow IRQ sharing
+ meaning that the IRQs it grabs won't be available to other
+ controllers sharing those IRQs which usually makes drivers
+ for those controllers fail. Generally, it's not a good idea
+ to load IDE generic driver on modern systems.

+/* Some documentation about various registers as determined by trial and error.
+ When the register addresses differ between the 7202 and the 7311 the 2
+ different addresses are written as 7302addr/7311addr, when one of the 2
+ addresses is a - sign that register description is not valid for the
+ matching IC.
+
+ Register page 1:
+
+ Address Description
+ -/0x08 Unknown compressor related, must always be 8 except when not
+ in 640x480 resolution and page 4 reg 2 <= 3 then set it to 9 !
+ -/0x1b Auto white balance related, bit 0 is AWB enable (inverted)
+ bits 345 seem to toggle per color gains on/off (inverted)
+ 0x78 Global control, bit 6 controls the LED (inverted)
+ -/0x80 JPEG compression ratio ? Best not touched
+
+ Register page 3/4:
+
+ Address Description
+ 0x02 Clock divider 2-63, fps =~ 60 / val. Must be a multiple of 3 on
+ the 7302, so one of 3, 6, 9, ..., except when between 6 and 12?
+ -/0x0f Master gain 1-245, low value = high gain
+ 0x10/- Master gain 0-31
+ -/0x10 Another gain 0-15, limited influence (1-2x gain I guess)
+ 0x21 Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused
+ -/0x27 Seems to toggle various gains on / off, Setting bit 7 seems to
+ completely disable the analog amplification block. Set to 0x68
+ for max gain, 0x14 for minimal gain.
