2011-10-25Blackfin: bf537-stamp: Register adav801 codec and ASoC machine driverLars-Peter Clausen
There is already an entry in the spi device table for the codec, but the modalias was wrong. Also the config symbol name for the codec is wrong, so this is fixed as well.

2011-10-25Blackfin: merge asm/mutex.h into kbuild tooMike Frysinger
This header was being rewritten while the asm-generic kbuild support was in flight, so it missed out on the update. Punt the stub and use the kbuild now that everything has settled. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-10-25Blackfin: bf537-stamp: fix ad1836 nameScott Jiang
The ASoC codec name is "ad1836" and not "ad183x" as the change to rename things ultimately did not get merged. Signed-off-by: Scott Jiang <scott.jiang.linux@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-10-25Blackfin: kgdb_test: rework code to avoid -O0 usageSonic Zhang
__kfree_rcu() in rcupdate.h bugs when parameter offset is not a constant at compile time. Since we build the kgdb_test module with -O0 and it includes this header file, we hit the bug. So drop the -O0 and mark the one func we need for the test as noinline (so we can set a breakpoint on it and have it be hit).

2011-10-25Blackfin: H8606: fixup bogus ioresource initThomas Gleixner
IRQF_SHARED is not part of the IORESOURCE_IRQ bits. It's expressed by IORESOURCE_IRQ_SHAREABLE. IORESOURCE_IRQ_HIGHEDGE and IRQF_TRIGGER_HIGH are contradicting values, an interrupt can hardly be configured for both level and edge at the same time. This was introduced in commit 45138439(Blackfin arch: flash memory map and dm9000 resources updating) of course without any hint in the changelog what the heck this is supposed to do.

2011-07-26atomic: cleanup asm-generic atomic*.h inclusionArun Sharma
After changing all consumers of atomics to include <linux/atomic.h>, we ran into some compile time errors due to this dependency chain: linux/atomic.h -> asm/atomic.h -> asm-generic/atomic-long.h where atomic-long.h could use funcs defined later in linux/atomic.h without a prototype. This patches moves the code that includes asm-generic/atomic*.h to linux/atomic.h. Archs that need <asm-generic/atomic64.h> need to select CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it unconditionally). Compile tested on i386 and x86_64 with allnoconfig.

2011-07-23Blackfin: irqs: do not trace arch_local_{*,irq_*} functionsSteven Rostedt
Do not trace arch_local_save_flags(), arch_local_irq_*() and friends. Although they are marked inline, gcc may still make a function out of them and add it to the pool of functions that are traced by the function tracer. This can cause undesirable results (kernel panic, triple faults, etc). Add the notrace notation to prevent them from ever being traced.

2011-07-23Blackfin: bf526: restrict reboot workaround to 0.0 siliconMike Frysinger

2011-07-23Blackfin: bf51x: fix alternative portmux optionsMike Frysinger
The BF51x's alternative portmux Kconfig options were copy & pasted from the BF52x, but never tweaked to reflect it. So drop the old options as they were never used (and were simply wrong), and add the BF51x specific pieces to the Kconfig and header. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: bf54x: fix GPIO resume codeMike Frysinger
Back in commit c03c2a87347b849ec927d, we fixed logic in the non-bf54x GPIO resume code to set the data levels properly before the direction to avoid spurious line glitches. But we missed the bf54x code paths. So add the same fix there. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: dpmc: optimize SDRAM programming slightlyMike Frysinger
No need to reload these registers constantly since they're always available (we're not making any function calls in between). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: dpmc: don't save/restore scratch registersMike Frysinger
The Blackfin C ABI says we do not need to save/restore R0-R3 and P0-P2 as they are available as scratch registers. So don't bother. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: bf538: pull gpio/port logic out of core hibernate pathsMike Frysinger
Re-architect how we save/restore the gpio/port logic that only pertains to bf538/bf539 parts by pulling it out of the core code paths and pushing it out to bf538-specific locations. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: dpmc: optimize hibernate/resume pathMike Frysinger
The current save logic used in hibernation is to do a MMR load (base + offset) into a register, and then push that onto the stack. Then when restoring, pop off the stack into a register followed by a MMR store (base + offset). These use plenty of 32bit insns rather than 16bit, are pretty long winded, and full of pipeline bubbles. So, by taking advantage of MMRs that are contiguous, the multi-register push/pop insn, and register abuse, we can shrink this code considerably. When saving, the new logic does a lot of loads into the data and pointer registers before executing a single multi-register push insn. Then when restoring, we do a single multi-register pop insn followed by a lot of stores. Overall, this allows us to cut the insn count by ~30%, the code size by ~45%, and drastically reduce the register hazards that trigger bubbles in the pipeline.

2011-07-23Blackfin: dpmc: do not save/restore EVT0/EVT1/EVT4 when hibernatingMike Frysinger
EVT0 is for emulation, EVT1 is for reset, and EVT4 is the "global int disable" region. None of these are used by software (or even hardware), so don't bother saving/restoring them when we hibernate since nothing ever uses these in Linux (the only thing they would be useful for is core-memory scratch, but that's just crazy talk). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: dpmc: relocate hibernate helper macrosMike Frysinger
This defines only get used in the hibernate code, so remove them from the global dpmc header as no one else cares. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: dpmc: omit RETE/RETN when hibernatingMike Frysinger
The RETE/RETN registers are only used in emulation(JTAG) and NMI nodes, or as scratch registers, neither of which need to be saved/restored as this code doesn't execute at those core event levels. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-23Blackfin: dpmc: optimize SIC_IWR programming a littleMike Frysinger

2011-07-23Blackfin: gpio/ints: generalize pint logicMike Frysinger

2011-07-23Blackfin: gpio: punt unused GPIO_# definesMike Frysinger
