2012-02-21ARM: remove disable_fiq and arch_ret_to_user macrosRob Herring
Now that most platforms don't need disable_fiq and arch_ret_to_user macros, we can remove the empty macros or empty entry-macro.S files.

2012-02-21PCMCIA: sa11x0: simpad: convert to use new irq/gpio managementRussell King
Convert Simpad socket driver to use the new irq/gpio management. This is slightly more involved because we have to touch the private platform header file to modify the GPIO bitmasks to be GPIO numbers.

2012-02-21FB: sa1100: remove global sa1100fb_.*_power function pointersRussell King
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>

2012-02-09ARM: sa11x0: neponset: don't static map neponset registersRussell King
Now that we ioremap() the neponset register space, there's no need to static map the neponset registers. Get rid of this static mapping. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: move register definitions to neponset.cRussell King
Move the board specific neponset register definitions to the board file, rather than mach/neponset.h. However, as the NCR_0 register definitions are used by some drivers, leave these behind. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: assabet/neponest: create neponset device in assabet.cRussell King
The neponset board is a daughter board for the Assabet. Create the neponset platform device in assabet.c, where we don't have to wrap it with machine_is_assabet() stuff. We also create this device dynamically rather than keeping it as a static device. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: suspend/resume in _noirq stateRussell King
Suspend and resume in the _noirq state, so that we're saving the state of the modem control signals as late as possible, and restoring them as early as possible. There's nothing to do in thaw/poweroff methods as we've already saved the necessary state. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: place smc91x and sa1111 resources in neponset deviceRussell King
Complete the neponset device resources by covering the children's memory resources in the parent neponset device. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: get parent IRQ from neponset device resourceRussell King
Obtain the parent IRQ from the neponset device resource rather than hard-coding it into the code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: implement support for sparse IRQsRussell King
Implement the necessary allocation/freeing functionality to support sparse IRQs with the Neponset device. On non-sparse IRQ platforms, this allows us to dynamically allocate from within the available IRQ number space. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: dynamically create neponset child devicesRussell King
Use platform_device_register_full() to dynamically create the various neponset child platform devices, and place them below the neponset device itself to ensure proper PM ordering and device structure. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: save and restore MDM_CTL_0Russell King
Save and restore the modem output control register across a suspend/ resume, as well as the NCR register. Place these in a locally allocated data structure rather than needing a new static variable. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: add driver .owner initializerRussell King
Ensure that the driver .owner field is properly initialized. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: shuffle some code aroundRussell King
Move the IRQ handler along side the rest of the IRQ code, and rearrange the include files. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: provide function to manipulate NCR_0Russell King
Rather than having direct register accesses to NCR_0 scattered amongst the code, provide a function instead. This contains the necessary race protection for this platform, ensuring that updates to this register are safe. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: neponset: fix interrupt setupRussell King
Since ARM was converted to genirq, the neponset IRQ implementation has gradually broken as a result of various subtle changes being introduced into genirq. It used to be that simple IRQs did not need an IRQ chip. This is no longer the case, and genirq barfs in irq_set_handler(). Fix this by introducing a dummy no-op chip, and registering it along with the flow handler. Neponset IRQs really don't have any masking ability - all we have is a status register to allow us to decode the source, and a three input OR gate inside a CPLD. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: assabet: ensure that GPIO27 is drivenRussell King
GPIO27 is just connected to a CPLD input without any pull-ups or pull- downs. If GPIO27 is left as an input, it will float around mid-supply, which for CMOS inputs is the worst place for a pin to be. Ensure that this pin is driven. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: assabet: avoid glitching GPIOs when setting outputsRussell King
Avoid glitching the GPIO signals during initialization, which can have undesirable effects. Ensure that the desired pin state is set before we change the GPIO pin direction to be an output. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Convert StrongARM-11x0 platforms and core SoC code to use the DEFINE_RES_xxx macros. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: fix section mismatch warningsRussell King
Neponset calls sa1110_mb_disable() from __devinit code, but sa1110_mb_disable() is marked __init, and so causes a section mismatch warning. As sa1110_mb_enable() and sa1110_mb_disable() need to be callable from suspend/resume paths as well, they must not be marked __init or __devinit. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: fix sleep entryRussell King
Sometimes, we get stuck while trying to enter sleep. This seems to occur if we do not have udelay() in the instruction cache. Avoid this by requesting a short delay prior to modifying the SDRAM timings. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-09ARM: sa11x0: fix off-by-one resource sizesRussell King
Hackkit defined its flash memory resource to be 32M + 1 byte. Jornada defined the Epson video controller resources to be one byte larger than they should be, and mis-mapped the SA-1111 companion chip one byte smaller than it should be. Fix these.

2012-02-03MFD: mcp-sa11x0: convert mcp-sa11x0 to use platform resourcesRussell King
Patch taken from af9081ae64 (ARM: sa1100: Refactor mcp-sa11x0 to use platform resources.) by Jochen Friedrich <jochen@scram.de>, and fixes applied. We can safely do this now that we have sanitized host removal; the original patch had use-after-free bugs in the removal code. Not only that, but there was no checking of the ioremap() return. The final change over Jochen's patch is that we wrap the base pointer selection inside the various register indexes, which reduces the possibility of the wrong register index being used.

Patch taken from af9081ae64 (ARM: sa1100: Refactor mcp-sa11x0 to use platform resources.) by Jochen Friedrich <jochen@scram.de>, and consolidated to use a common function. Move the setup of the PPC unit out of mcp-sa11x0 into the core SA11x0 code, and call it from each platforms initialization file. This centralizes the setup of the PPC unit while not polluting the mcp-sa11x0 driver with these details.

2012-01-20Revert "ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp ↵Russell King
bus." This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7. Conflicts: scripts/mod/file2alias.c This change is wrong on many levels. First and foremost, it causes a regression. On boot on Assabet, which this patch gives a codec id of 'ucb1x00', it gives: ucb1x00 ID not found: 1005 0x1005 is a valid ID for the UCB1300 device. Secondly, this patch is way over the top in terms of complexity. The only device which has been seen to be connected with this MCP code is the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same driver. Adding a match table, requiring the codec string to match the hardware ID read out of the ID register, etc is completely over the top when we can just read the hardware ID register.
