2012-03-24ARM: sa1111: use dev_err() rather than printk()Russell King
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 King
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 King
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 King
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: provide a generic way to prevent devices from registeringRussell King
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>
2012-02-09ARM: sa1111: change devid to be a bitmaskRussell King
Change the sa1111 device id to be a bitmask. This allows us to specify the actual device, while allowing a single driver to bind to both PS2 devices. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa1111: add platform enable/disable functionsRussell King
Add platform hooks to be called when individual sa1111 devices are enabled and disabled. This will allow us to move some platform specifics out of the individual drivers. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa1111: add shutdown hook to sa1111_driver structureRussell King
Add a shutdown hook to the sa1111_driver structure to allow drivers to be notified of system reboots and shutdowns. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa1111: implement support for sparse IRQsRussell King
Implement the necessary allocation/freeing functionality to support sparse IRQs with the SA-1111 device. On non-sparse IRQ platforms, this allows us to dynamically allocate from within the available IRQ number space. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa1111: finish "allow cascaded IRQs to be used by platforms"Russell King
Commit 19851c58e680 (sa1111: allow cascaded IRQs to be used by platforms) moved the IRQ definitions to the .c file, and added an irq_base member to the private data structure. The inerrupt demultiplexer uses irq_base, but the interrupt setup code does not. Also, although the commit adds a private data structure to pass this data, it isn't even referenced, resulting in irq_base being zero. We also copied the IRQ numbers from the device info array into the actual devices, resulting in wrong interrupt numbers passed to the sub-devices. The net effect of this is that we always overwrite IRQs 0-54, even if they are allocated elsewhere in the system. Add the code necessary to setup the private irq_base, and use it in the IRQ setup code. Make the SA-1111 probe fail with -EINVAL if there is no platform data provided.

2012-02-09ARM: sa1111: fix PWM state on suspendRussell King
We should not write to the SA1111 registers after setting the SLEEP bit. Moreover, the manual says that the PWM registers should be disabled before we enter sleep. So, move the clearing of these registers earlier in the suspend sequence. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa1111: fix memory request/grant setup on PM eventsRussell King
We weren't re-enabling the memory request/grant signals on resume, causing DMA devices on the sa1111 to fail. Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-05-12ARM: use ARM_DMA_ZONE_SIZE to adjust the zone sizesRussell King
Rather than each platform providing its own function to adjust the zone sizes, use the new ARM_DMA_ZONE_SIZE definition to perform this adjustment. This ensures that the actual DMA zone size and the ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS definitions are consistent with each other, and moves this complexity out of the platform code.

2010-07-30SA1111: Eliminate use after freeJulia Lawall
__sa1111_remove always frees its argument, so the subsequent reference to sachip->saved_state represents a use after free. __sa1111_remove does not appear to use the saved_state field, so the patch simply frees it first. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E,E2; @@ __sa1111_remove(E) ...

2010-05-27ARM: 6146/1: sa1111: Prevent deadlock in resume pathMarek Vašut
This patch reorganises the sa1111_resume() function in a manner the spinlock happens after calling the sa1111_wake(). This fixes two bugs: 1) This function called sa1111_wake() which tried to claim the same spinlock the sa1111_resume() already claimed. This would result in certain deadlock. Original idea for this part: Russell King <rmk+kernel@arm.linux.org.uk> 2) The function didn't unlock the spinlock in case the chip didn't report correct ID.
