2012-03-26ARM: sa11x0: remove unused DMA controller definitionsRussell King2-218/+3
Remove the new unused DMA controller definitions from mach/SA-1100.h. These are now private to the SA-11x0 DMA engine driver and contained within the driver. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-26ARM: sa11x0: remove old SoC private DMA driverRussell King3-466/+1
Now that all users are converted over to using the DMA engine API, we can get rid of the old platform dependent DMA driver. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2012-03-24USB: sa1111: add hcd .reset methodRussell King1-9/+11
Add the .reset method to the HCD, and update the .start method accordingly for this change. Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24USB: sa1111: add OHCI shutdown methodsRussell King1-0/+12
Add OHCI shutdown methods to cleanly shutdown the OHCI controller on system shutdowns and reboots. This avoids the controller continuing to run should be soft-reboot the platform, potentially scribbling over system memory. Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24USB: sa1111: reorganize ohci-sa1111.cRussell King1-134/+93
Combine usb_hcd_sa1111_probe() and ohci_hcd_sa1111_drv_probe(), doing the same for the remove methods. Move sa1111_start_hc and sa1111_stop_hc to be located next to these the probe/release functions, as they're only called from them. Get rid of the /*----*/ breaker lines. Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24USB: sa1111: get rid of nasty printk(KERN_DEBUG "%s: ...", __FILE__)Russell King1-4/+2
Use dev_dbg() instead, it's more friendly. Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24USB: sa1111: sparse and checkpatch cleanupsRussell King1-16/+17
Clean up the ohci-sa1111 driver formatting to be more compliant with current standards, and add 'static' to various function definitions to avoid sparse complaints about undeclared functions. Remove the unnecessary local declaration of 'usb_disabled', which can be found instead in linux/usb.h. Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24ARM: sa11x0: don't static map sa1111Russell King3-15/+0
The sa1111 support will ioremap() the device; there is no need for platforms to setup a static mapping for this. Remove the static mapping for this device from badge4, jornada720 and neponset. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24ARM: sa1111: use dev_err() rather than printk()Russell King1-1/+1
Use dev_err() to report device specific errors rather than printk(). Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24ARM: sa1111: cleanup sub-device registration and unregistrationRussell King1-11/+16
Move the releasing of resources out of the release function - this allows a cleaner and more conventional arrangement of the registration failure paths and a saner unregistration process for these devices. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24ARM: sa1111: only setup DMA for DMA capable devicesRussell King1-3/+6
It's pointless registering the PS/2 interfaces with the dmabounce code when there's no DMA support for these in hardware, so only setup the DMA masks for two subdevices which support DMA - the OHCI and SAC. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24ARM: sa1111: register sa1111 devices with dmabounce in bus notifierRussell King1-55/+74
Use the bus notifier to register sa1111 devices with dmabounce, rather than after the device has been registered, potentially racing with driver binding. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24ARM: sa1111: move USB interface register definitions to ohci-sa1111.cRussell King2-30/+25
Move the USB interface register definitions into the driver, rather than keeping them in a common place. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24ARM: sa1111: move PCMCIA interface register definitions to sa1111_generic.cRussell King2-48/+41

2012-03-24ARM: sa1111: delete unused physical GPIO register definitionsRussell King1-16/+0
Get rid of the unused GPIO register definitions - we access GPIO registers through the base + offset method, and having the phys address definitions is unnecessary duplication. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-24ARM: sa1111: provide a generic way to prevent devices from registeringRussell King6-5/+7
Some platforms don't want certain devices to be registered, because, eg, the interface is not wired. Provide a way for platforms to prevent various devices from being registered via a devid bitmask in the platform data. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-07NET: sa11x0-ir: add DMA support for SIR transmit modeRussell King1-44/+59
As the DMA engine API allows DMA channels to be reconfigured on the fly, we can now support switching the DMA channel configuration to support SIR transmit DMA without needing to claim an additional physical DMA channel - thereby using up half the DMA channels just for one driver. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-07NET: sa11x0-ir: convert sa11x0-ir driver to use DMA engine APIRussell King2-30/+92
Convert the sa11x0 IrDA driver to use the sa11x0 DMA engine driver rather than our own platform specific DMA API. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-07Merge branch 'sa11x0-dma' into sa11x0-irRussell King5-0/+1168
2012-03-07ARM: sa11x0: add SA-11x0 DMA deviceRussell King1-0/+25
Add sa11x0 DMA platform device and resources to the list of generic platform devices for SA11x0 machines. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-07DMA: sa11x0: add SA-11x0 DMA driverRussell King4-0/+1143
Add support for the SA-11x0 DMA driver, which replaces the private API version in arch/arm/mach-sa1100/dma.c. We model this as a set of virtual DMA channels, one for each request signal, and assign the virtual DMA channel to a physical DMA channel when there is work to be done. This allows DMA users to claim their channels, and hold them while not in use, without affecting the availability of the physical channels. Another advantage over this approach, compared to the private version, is that a channel can be reconfigured on the fly without having to release and re-request it - which for the IrDA driver, allows us to use DMA for SIR mode transmit without eating up three physical channels. As IrDA is half-duplex, we actually only need one physical channel, and this architecture allows us to achieve that. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-24FB: sa11x0: convert to use platform resource and ioremap()Russell King3-35/+54
Convert the sa11x0 framebuffer driver to obtain the base address of its hardware registers from the platform resources, and ioremap this rather than relying on the static mappings. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa11x0: convert shannon display enable accesses to use GPIO subsystemRussell King2-9/+17
Rather than accessing GPSR and GPCR directly, use the GPIO subsystem instead. Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa11x0: fix shannon GPSR/GPCR accessesRussell King1-2/+2
The GPIO set and clear registers should only be written, rather than read, modified, and written. A read-modify-write will have undesired side effects. Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa1100: make GPIO configuration setting safeRussell King1-0/+11
The sa1100fb driver needs to set the GPIO direction and alternate function register according to the panel that we're driving. We've done this in the driver by read-modify-writing the register, which may cause problems with races. Fix this with a minimal change. Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa1100: use inf members directlyRussell King2-29/+12
Now that the LCD information is available while the driver is loaded, we don't need to cache that information into our driver private data structure. Get rid of it. Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa1100: remove assabet specific initializationRussell King1-8/+0
Remove the assabet specific initialization for PAL output mode - we call the lcd_power function before we enable the LCD controller, which will disable the LCD panel to prevent it receiving incorrect timings. Therefore, this setup here is redundant. Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa1100: remove global sa1100fb_.*_power function pointersRussell King8-64/+79
Now that we have platform data contained within the individual board code, we can get rid of the global function pointers, placing them inside the platform data instead. Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa1100: move platform data to platform filesRussell King9-238/+218

2012-02-21FB: sa1100: combine RGB bitfield overrides into sa1100fb_mach_infoRussell King2-19/+24
Allow the sa1100fb_mach_info structure to carry the RGB bitfield overrides, rather than requiring them to be separately initialized in sa1100fb_get_machine_info(). Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa1100: convert printks to dev_xxx()Russell King2-47/+34
Use the dev_xxx() macros for driver kernel message output, rather than open coded printk() with KERN_ levels etc. Remove DPRINTK(). Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-21FB: sa1100: constify rgb structuresRussell King2-5/+5

2012-02-21FB: sa1100: add .owner initializer to driver structureRussell King1-0/+1
Annotate the driver structure with the .owner field, to allow the module to be associated with the driver. Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2012-02-19MFD: mcp-sa11x0/assabet: move assabet reset handling out of mcp-sa11x0.cRussell King2-6/+8
Move the assabet specific reset handling out of mcp-sa11x0.c, into its board file. This leaves the mcp code free from all board specific details. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-19MFD: ucb1x00-assabet: add support for UCB1x00 GPIO switchesRussell King1-4/+39
Add support for UCB1x00 GPIO buttons found on the Assabet platform. We can now trivially support these buttons as we have standardized gpiolib, genirq and gpio keyboard support in place for this device.

2012-02-19ARM: sa11x0: add assabet ucb1x00 platform dataRussell King1-0/+6
Add ucb1x00 platform data to enable GPIO support on the UCB1300 device. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-19MFD: ucb1x00-core: add wakeup supportRussell King2-0/+63
Add genirq wakeup support for the ucb1x00 device. This allows an attached gpio_keys driver to wakeup the system. Touchscreen is also possible. When there are no wakeup sources, ask the platform to assert the reset signal to avoid any unexpected behaviour; this also puts the reset signal at the right level when power is removed from the device. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-19MFD: ucb1x00: convert to use genirqRussell King4-179/+132
Convert the ucb1x00 driver to use genirq's interrupt services, rather than its own private implementation. This allows a wider range of drivers to use the GPIO interrupts (such as the gpio_keys driver) without being aware of the UCB1x00's private IRQ system. This prevents the UCB1x00 core driver from being built as a module, so adjust the configuration to add that restriction.
