+Subject: [PATCH] pxa2xx-ac97: switch AC unit to correct state before probing
+
+If AC97 unit is in partially enabled state, early request_irq can trigger
+IRQ storm or even full hang up. Workaround this by forcibly switching ACLINK off
+at the start of the probe.

+Subject: [PATCH 03/64] Core MFD support
+
+This patch provides a common subdevice registration system for MFD type
+chips, using platfrom device.
+
+It also provides a new resource type for IRQs such that a subdevices IRQ may
+be computed based on the MFD cores IRQ handler, since many MFDs provide an IRQ
+multiplex.

++ * Bus glue for Toshiba Mobile IO(TMIO) Controller's OHCI core
++ *(C) Copyright 2005 Chris Humbert <mahadri-usb@drigon.com>
++ *
++ * This is known to work with the following variants:
++ * TC6393XB revision 3 (32kB SRAM)
++ *
++ * The TMIO's OHCI core DMAs through a small internal buffer that
++ * is directly addressable by the CPU. dma_declare_coherent_memory
++ * and DMA bounce buffers allow the higher-level OHCI host driver to
++ * work. However, the dma API doesn't handle dma mapping failures
++ * well(dma_sg_map() is a prime example), so it is unusable.
++ *
++ * This HC pretends be a PIO-ish controller and uses the kernel's
++ * generic allocator for the entire SRAM. Using the USB core's
++ * usb_operations, we provide hcd_buffer_alloc/free. Using the OHCI's
++ * ohci_ops, we provide memory management for OHCI's TDs and EDs. We
++ * internally queue a URB's TDs until enough dma memory is available
++ * to enqueue them with the HC.
++ *

+Subject: [PATCH 13/64] USB: gadget: pxa2xx_udc supports inverted vbus
+
+Some boards (like e.g. Tosa) invert the VBUS-detection signal:
+it's low when a host is supplying VBUS, and high otherwise.
+Allow specifying whether gpio_vbus value is inverted.

+Subject: [PATCH 19/64] pxa: remove periodic mode emulation support
+
+Apparantly, the generic time subsystem can accurately emulate periodic
+mode via the one-shot support code, so we don't need our own periodic
+emulation code anymore. Just ensure that we build support for one shot
+into the generic time subsystem.

+Date: Fri, 18 Jan 2008 00:35:00 +0300
+Subject: [PATCH 21/64] Add an empty drivers/gpio directory for gpiolib infrastructure and GPIO
+ expanders. It will be populated by later patches.
+
+This won't be the only place to hold such gpio_chip code. Many external chips
+add a few GPIOs as secondary functionality (such as MFD drivers) and platform
+code frequently needs to closely integrate GPIO and IRQ support.
+
+This is placed *early* in the build/link sequence since it's common for other
+drivers to depend on GPIOs to do their work, so they must be initialized early
+in the device_initcall() sequence.

+From: David Brownell <dbrownell@users.sourceforge.net>
+Date: Fri, 18 Jan 2008 00:35:20 +0300
+Subject: [PATCH 22/64] Provide new implementation infrastructure that platforms may choose to use
+ when implementing the GPIO programming interface. Platforms can update their
+ GPIO support to use this. In many cases the incremental cost to access a
+ non-inlined GPIO should be less than a dozen instructions, with the memory
+ cost being about a page (total) of extra data and code. The upside is:
+
+ * Providing two features which were "want to have (but OK to defer)" when
+ GPIO interfaces were first discussed in November 2006:
+
+ - A "struct gpio_chip" to plug in GPIOs that aren't directly supported
+ by SOC platforms, but come from FPGAs or other multifunction devices
+ using conventional device registers (like UCB-1x00 or SM501 GPIOs,
+ and southbridges in PCs with more open specs than usual).
+
+ - Full support for message-based GPIO expanders, where registers are
+ accessed through sleeping I/O calls. Previous support for these
+ "cansleep" calls was just stubs. (One example: the widely used
+ pcf8574 I2C chips, with 8 GPIOs each.)
+
+ * Including a non-stub implementation of the gpio_{request,free}() calls,
+ making those calls much more useful. The diagnostic labels are also
+ recorded given DEBUG_FS, so /sys/kernel/debug/gpio can show a snapshot
+ of all GPIOs known to this infrastructure.
+
+The driver programming interfaces introduced in 2.6.21 do not change at all;
+this infrastructure is entirely below those covers.

++ * @direction_input: configures signal "offset" as input, or returns error
++ * @get: returns value for signal "offset"; for output signals this
++ * returns either the value actually sensed, or zero
++ * @direction_output: configures signal "offset" as output, or returns error
++ * @set: assigns output value for signal "offset"
++ * @dbg_show: optional routine to show contents in debugfs; default code
++ * will be used when this is omitted, but custom code can show extra
++ * state (such as pullup/pulldown configuration).
++ * @base: identifies the first GPIO number handled by this chip; or, if
++ * negative during registration, requests dynamic ID allocation.
++ * @ngpio: the number of GPIOs handled by this controller; the last GPIO
++ * handled is (base + ngpio - 1).
++ * @can_sleep: flag must be set iff get()/set() methods sleep, as they
++ * must while accessing GPIO expander chips over I2C or SPI
++ *
++ * A gpio_chip can help platforms abstract various sources of GPIOs so
++ * they can all be accessed through a common programing interface.
++ * Example sources would be SOC controllers, FPGAs, multifunction
++ * chips, dedicated GPIO expanders, and so on.
++ *
++ * Each chip controls a number of signals, identified in method calls
++ * by "offset" values in the range 0..(@ngpio - 1). When those signals
++ * are referenced through calls like gpio_get_value(gpio), the offset
++ * is calculated by subtracting @base from the gpio number.

+From: Philipp Zabel <philipp.zabel@gmail.com>
+Date: Tue, 12 Feb 2008 04:38:12 +0300
+Subject: [PATCH 23/64] This adds gpiolib support for the PXA architecture:
+ - move all GPIO API functions from generic.c into gpio.c
+ - convert the gpio_get/set_value macros into inline functions
+
+This makes it easier to hook up GPIOs provided by external chips like
+ASICs and CPLDs.

++
++
++GPIO implementor's framework (OPTIONAL)
++=======================================
++As noted earlier, there is an optional implementation framework making it
++easier for platforms to support different kinds of GPIO controller using
++the same programming interface.
++
++As a debugging aid, if debugfs is available a /sys/kernel/debug/gpio file
++will be found there. That will list all the controllers registered through
++this framework, and the state of the GPIOs currently in use.
++
++
++Controller Drivers: gpio_chip
++-----------------------------
++In this framework each GPIO controller is packaged as a "struct gpio_chip"
++with information common to each controller of that type:
++
++ - methods to establish GPIO direction
++ - methods used to access GPIO values
++ - flag saying whether calls to its methods may sleep
++ - optional debugfs dump method (showing extra state like pullup config)
++ - label for diagnostics
++
++There is also per-instance data, which may come from device.platform_data:
++the number of its first GPIO, and how many GPIOs it exposes.
++
++The code implementing a gpio_chip should support multiple instances of the
++controller, possibly using the driver model. That code will configure each
++gpio_chip and issue gpiochip_add(). Removing a GPIO controller should be
++rare; use gpiochip_remove() when it is unavoidable.
++
++Most often a gpio_chip is part of an instance-specific structure with state
++not exposed by the GPIO interfaces, such as addressing, power management,
++and more. Chips such as codecs will have complex non-GPIO state,
++
++Any debugfs dump method should normally ignore signals which haven't been
++requested as GPIOs. They can use gpiochip_is_requested(), which returns
++either NULL or the label associated with that GPIO when it was requested.
++
++
++Platform Support
++----------------
++To support this framework, a platform's Kconfig will "select HAVE_GPIO_LIB"
++and arrange that its <asm/gpio.h> includes <asm-generic/gpio.h> and defines
++three functions: gpio_get_value(), gpio_set_value(), and gpio_cansleep().
++They may also want to provide a custom value for ARCH_NR_GPIOS.
++
++Trivial implementations of those functions can directly use framework
++code, which always dispatches through the gpio_chip:
++
++ #define gpio_get_value __gpio_get_value
++ #define gpio_set_value __gpio_set_value
++ #define gpio_cansleep __gpio_cansleep
++
++Fancier implementations could instead define those as inline functions with
++logic optimizing access to specific SOC-based GPIOs. For example, if the
++referenced GPIO is the constant "12", getting or setting its value could
++cost as little as two or three instructions, never sleeping. When such an
++optimization is not possible those calls must delegate to the framework
++code, costing at least a few dozen instructions. For bitbanged I/O, such
++instruction savings can be significant.
++
++For SOCs, platform-specific code defines and registers gpio_chip instances
++for each bank of on-chip GPIOs. Those GPIOs should be numbered/labeled to
++match chip vendor documentation, and directly match board schematics. They
++may well start at zero and go up to a platform-specific limit. Such GPIOs
++are normally integrated into platform initialization to make them always be
++available, from arch_initcall() or earlier; they can often serve as IRQs.
++
++
++Board Support
++-------------
++For external GPIO controllers -- such as I2C or SPI expanders, ASICs, multi
++function devices, FPGAs or CPLDs -- most often board-specific code handles
++registering controller devices and ensures that their drivers know what GPIO
++numbers to use with gpiochip_add(). Their numbers often start right after
++platform-specific GPIOs.
++
++For example, board setup code could create structures identifying the range
++of GPIOs that chip will expose, and passes them to each GPIO expander chip
++using platform_data. Then the chip driver's probe() routine could pass that
++data to gpiochip_add().
++
++Initialization order can be important. For example, when a device relies on
++an I2C-based GPIO, its probe() routine should only be called after that GPIO
++becomes available. That may mean the device should not be registered until
++calls for that GPIO can work. One way to address such dependencies is for
++such gpio_chip controllers to provide setup() and teardown() callbacks to
++board specific code; those board specific callbacks would register devices
++once all the necessary resources are available.

+Subject: [PATCH 26/64] I don't think we should check for IRQs when determining which one
+ of power supplies to register. Better use is_{ac,usb}_online
+ callbacks, this will not produce an obstacle to implement polling --
+ when irqs aren't mandatory. I'll send my two pending patches to show
+ the idea.
+
+For this particular issue, I think something like that should work.
+If it works for you, I'll commit that version, preserving your
+authorship, of course.

+Subject: [PATCH 30/64] Core driver for WM97xx touchscreens
+
+This patch series adds support for the touchscreen controllers provided
+by Wolfson Microelectronics WM97xx series chips in both polled and
+streaming modes.
+
+These drivers have been maintained out of tree since 2003. During that
+time the driver the primary maintainer was Liam Girdwood and a number of
+people have made contributions including Stanley Cai, Rodolfo Giometti,
+Russell King, Marc Kleine-Budde, Ian Molton, Vincent Sanders, Andrew
+Zabolotny, Graeme Gregory, Mike Arthur and myself. Apologies to anyone
+I have omitted.

+Subject: [PATCH 37/64] Don't lock the codec list in snd_soc_dapm_new_widgets()
+
+snd_soc_dapm_new_widgets() takes the codec lock when adding new widgets,
+causing lockdep warnings when applications later call down through ALSA
+to adjust controls. Since widgets are only added during probe this lock
+should be unneeded so don't take it.
+
