2009-12-13mfd: Near complete mc13783 rewriteUwe Kleine-König2-217/+111
This fixes several things while still providing the old API: - simplify and fix locking - better error handling - don't ack all irqs making it impossible to detect a reset of the rtc - use a timeout variant to wait for completion of ADC conversion - provide platform-data to regulator subdevice (This allows making struct mc13783 opaque for other drivers after the regulator driver is updated to use its platform_data.) - expose all interrupts - use threaded irq After all users in mainline are converted to the new API, some things (e.g. mc13783-private.h) can go away.

2009-12-13mfd: Move WM831x to generic IRQMark Brown2-11/+30
Replace the wm831x-local IRQ infrastructure with genirq, allowing access to the diagnostic infrastructure of genirq and allowing us to implement interrupt support for the GPIOs. The switchover is done within the wm831x specific IRQ API, further patches will convert the individual drivers to use genirq directly.

2009-12-13mfd: Initial support for twl5031Ilkka Koskinen1-6/+41

2009-12-13mfd: Convert wm8350 IRQ handlers to irq_handler_tMark Brown1-4/+4
This is done as simple code transformation, the semantics of the IRQ API provided by the core are are still very different to those of genirq (mainly with regard to masking). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-12-13mfd: Allow configuration of VDCDC2 for tps65010Ben Dooks1-0/+19
Add function to allow the configuation fo the VDCDC2 register by external users, to allow changing of the standard and low-power running modes. This is needed, for example, for the Simtec IM2440D20 where we need to use the low-power mode to shutdown the LDO/DCDC that are not needed during suspend (saving substantial power) and the runtime use of the low-power mode to change VCore.

2009-12-13mfd: fix undefined twl4030-power resconfig value checksAaro Koskinen1-0/+1
The code tries to skip values initialized with -1, but since the values are unsigned the comparison is always true.

2009-12-13mfd: Fix memleak in pcf50633_client_dev_registerLars-Peter Clausen1-5/+5
Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata.

2009-12-13mfd: Convert WM835x IRQ handling to use a data tableMark Brown1-0/+18
Rather than open coding individual IRQs in each function which manipulates them store data for IRQs in a table which is then referenced in the users. This is a substantial code shrink and should be a performance win in cases where only a single IRQ goes off at once since instead of reading four of the second level IRQ registers for each interrupt we read only the sub-registers which have had an interrupt flagged.

2009-12-13mfd: Split wm8350 IRQ code into a separate fileMark Brown1-1/+3
In preparation for refactoring - it's over 700 lines of well-isolated code and having it in a file by itself makes things more managable. While we're at it make sure that we clean up the IRQ if we fail after acquiring it on init.

2009-12-13spi: SuperH MSIOF SPI Master driver V2Magnus Damm1-0/+10
This patch is V2 of SPI Master support for the SuperH MSIOF. Full duplex, spi mode 0-3, active high cs, 3-wire and lsb first should all be supported, but the driver has so far only been tested with "mmc_spi". The MSIOF hardware comes with 32-bit FIFOs for receive and transmit, and this driver simply breaks the SPI messages into FIFO-sized chunks. The MSIOF hardware manages the pins for clock, receive and transmit (sck/miso/mosi), but the chip select pin is managed by software and must be configured as a regular GPIO pin by the board code. Performance wise there is still room for improvement, but on a Ecovec board with the built-in sh7724 MSIOF0 this driver gets Mini-sd read speeds of about half a megabyte per second. Future work include better clock setup and merging of 8-bit transfers into 32-bit words to reduce interrupt load and improve throughput.

2009-12-11USB: Refactor code to find alternate interface settings.Sarah Sharp1-0/+4
Refactor out the code to find alternate interface settings into usb_find_alt_setting(). Print a debugging message and return null if the alt setting is not found. While we're at it, correct a bug in the refactored code. The interfaces in the configuration's interface cache are not necessarily in numerical order, so we can't just use the interface number as an array index. Loop through the interface caches, looking for the correct interface. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11USB: usb-storage: add BAD_SENSE flagAlan Stern1-1/+3
This patch (as1311) fixes a problem in usb-storage: Some devices are pretty broken when it comes to reporting sense data. The information they send back indicates that they have more than 18 bytes of sense data available, but when the system asks for more than 18 they fail or hang. The symptom is that probing fails with multiple resets. The patch adds a new BAD_SENSE flag to indicate that usb-storage should never ask for more than 18 bytes of sense data. The flag can be set in an unusual_devs entry or via the "quirks=" module parameter, and it is set automatically whenever a REQUEST SENSE command for more than 18 bytes fails or times out. An unusual_devs entry is added for the Agfa photo frame, which uses a Prolific chip having this bug.

2009-12-11USB: prepare for changover to Runtime PM frameworkAlan Stern1-16/+10
This patch (as1303) revises the USB Power Management infrastructure to make it compatible with the new driver-model Runtime PM framework: Drivers are no longer allowed to access intf->pm_usage_cnt directly; the PM framework manages its own usage counters. usb_autopm_set_interface() is eliminated, because it directly sets intf->pm_usage_cnt. usb_autopm_enable() and usb_autopm_disable() are eliminated, because they call usb_autopm_set_interface(). usb_autopm_get_interface_no_resume() and usb_autopm_put_interface_no_suspend() are added. They correspond to pm_runtime_get_noresume() and pm_runtime_put_noidle() in the PM framework. The power/level attribute no longer accepts "suspend", only "on" and "auto". The PM framework doesn't allow devices to be forced into a suspended mode. The hub driver contains the only code that violates the new guidelines. It is updated to use the new interface routines instead. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11USB: remove the auto_pm flagAlan Stern1-2/+0
This patch (as1302) removes the auto_pm flag from struct usb_device. The flag's only purpose was to distinguish between autosuspends and external suspends, but that information is now available in the pm_message_t argument passed to suspend methods.

2009-12-11USB OTG: Add generic driver for ULPI OTG transceiverDaniel Mack1-0/+7
This adds a minimal generic driver for ULPI connected transceivers, using the OTG framework functions recently introduced. The driver got a table to match the ULPI chips, which currently only has one entry for NXP's ISP 1504 transceiver.

2009-12-11USB OTG: add support for ulpi connected external transceiversDaniel Mack1-1/+67
This adds support for OTG transceivers directly connected to the ULPI interface. In particular, the following details are added - a struct for low level io functions (read/write) - a priv field to be used as 'viewport' by low level access functions - an (*init) and (*shutdown) callbacks, along with static inline helpers - a (*set_vbus) callback to switch the port power on and off - a flags field for per-transceiver settings - some defines for the flags bitmask to configure platform specific details Signed-off-by: Daniel Mack <daniel@caiaq.de> Cc: Heikki Krogerus <ext-heikki.krogerus@nokia.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
