2012-02-16irq_domain: Remove 'new' irq_domain in favour of the ppc oneGrant Likely1-12/+2
This patch removes the simplistic implementation of irq_domains and enables the powerpc infrastructure for all irq_domain users. The powerpc infrastructure includes support for complex mappings between Linux and hardware irq numbers, and can manage allocation of irq_descs. This patch also converts the few users of irq_domain_add()/irq_domain_del() to call irq_domain_add_legacy() instead. v3: Fix bug that set up too many irqs in translation range. v2: Fix removal of irq_alloc_descs() call in gic driver Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: Olof Johansson <olof@lixom.net>

2012-02-13Merge branch 'omap-fixes-warnings' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds1-10/+10
This set of changes are fixing various section mismatch warnings which look to be completely valid. Primerily, those which are fixed are those which can cause oopses by manipulation of driver binding via sysfs. For example: calling code marked __init from driver probe __devinit functions. Some of these changes will be reworked at the next merge window when the underlying reasons are sorted out. In the mean time, I think it's important to have this fixed for correctness. Also included in this set are fixes to various error messages in OMAP - including making them gramatically correct, fixing a few spelling errors, and more importantly, making them greppable by unwrapping them. Tony Lindgren has acked all these patches, put them out for testing a week ago, and I've tested them on the platforms I have. * 'omap-fixes-warnings' of git://git.linaro.org/people/rmk/linux-arm: ARM: omap: resolve nebulous 'Error setting wl12xx data' ARM: omap: fix wrapped error messages in omap_hwmod.c ARM: omap: fix section mismatch warnings in mux.c caused by hsmmc.c ARM: omap: fix section mismatch warning for sdp3430_twl_gpio_setup() ARM: omap: fix section mismatch error for omap_4430sdp_display_init() ARM: omap: fix section mismatch warning for omap_secondary_startup() ARM: omap: preemptively fix section mismatch in omap4_sdp4430_wifi_mux_init() ARM: omap: fix section mismatch warning in mux.c ARM: omap: fix section mismatch errors in TWL PMIC driver ARM: omap: fix uninformative vc/i2c configuration error message ARM: omap: fix vc.c PMIC error message ARM: omap: fix prm44xx.c OMAP44XX_IRQ_PRCM build error

WARNING: drivers/mfd/built-in.o(.devinit.text+0x258): Section mismatch in reference from the function twl_probe() to the function .init.text:twl4030_power_init() The function __devinit twl_probe() references a function __init twl4030_power_init(). If twl4030_power_init is only used by twl_probe then annotate twl4030_power_init with a matching annotation. twl4030_power_init() references other __init marked functions, so these too must become __devinit.

2012-02-09ARM: omap: fix broken twl-core dependencies and ifdefsRussell King2-3/+5
In commit aeb5032b3f, a dependency on IRQ_DOMAIN was added, which causes regressions on previously working setups: a previously working non-DT kernel configuration now loses its PMIC support. The lack of PMIC support in turn causes the loss of other functionality the kernel had. This dependency was added because the driver now registers its interrupts with the IRQ domain code, presumably to prevent a build error. The result is that OMAP3 oopses in the vp.c code (fixed by a previous commit) due to the lack of PMIC support. However, even with IRQ_DOMAIN enabled, the driver oopses: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = c0004000 [00000000] *pgd=00000000 Internal error: Oops: 5 [#1] SMP Modules linked in: CPU: 1 Not tainted (3.3.0-rc2+ #271) PC is at irq_domain_add+0x1c/0x134 LR is at twl_probe+0xd0/0x370 pc : [<c007bad0>] lr : [<c029baac>] psr: 00000113 sp : df843c48 ip : df843c68 fp : df843c64 r10: c02b93e4 r9 : 00000000 r8 : c029b9dc r7 : df9d8a00 r6 : c03bef90 r5 : 00000000 r4 : c03f5240 r3 : 00000000 r2 : c03f5240 r1 : 00000015 r0 : c03f5240 Flags: nzcv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c5387d Table: 8000404a DAC: 00000015 Process swapper/0 (pid: 1, stack limit = 0xdf8422f0) Stack: (0xdf843c48 to 0xdf844000) 3c40: 00000014 00000170 00000014 c03bef90 df843c9c df843c68 3c60: c029baac c007bac0 00000000 df9d8a20 00000001 c03cd238 c02b93e4 df9d8a20 3c80: df9d8a04 df9d8a00 c029b9dc df8cae08 df843cc4 df843ca0 c01eee70 c029b9e8 ...

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.

2012-01-22MFD: ucb1x00-ts: fix resume failureRussell King1-27/+5
If the ucb1x00 touchscreen is resumed while the touchscreen is being touched, the main thread stops responding. This occurs because two things happen: 1. When we suspended, we were woken up, and executed the loop. Finding that the touchscreen was not pressed, we prepare to schedule for a maximum timeout, before being stopped in try_to_freeze(). 2. an irq occurs, we disable the irq, and mark it as disabled, and wake the thread. This wake occurs while the thread is still within __refrigerator() 3. The thread is unfrozen, and __refrigerator() sets the threads state back to INTERRUPTIBLE. We then drop into schedule_timeout() with an infinite timeout and the IRQ disabled. This prevents any further screen touches activating the thread. Fix this by using kthread_freezable_should_stop() which handles the freezing issues for us outside of the hotspot where the task state matters. Include a flag to ignore the touchscreen until it is released to avoid sending unintended data to the application. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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.

2012-01-09mfd: Still check other interrupts if we get a wm831x touchscreen IRQMark Brown1-2/+1
It is possible that we will see another interrupt triggering at the same time as the touchscreen interrupts so it's still worth checking other possible sources. Almost all of the win from the fast path comes from only needing to read the primary register and saving the I/O costs.

2012-01-09mfd: Introduce missing kfree in 88pm860x probe routineJulia Lawall1-0/+1
Error handling code following a kzalloc should free the allocated data. At this point, chip has been allocated and some fields have been initialized, but it has not been stored anywhere, so it should be freed before leaving the function. A simplified version of the semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr) // <smpl> @r exists@ local idexpression x; statement S; identifier f1; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } x->f1 ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2012-01-09mfd: Separate out STMPE controller and interface specific codeViresh Kumar5-90/+195
Few STMPE controller can have register interface over SPI or I2C. Current implementation only supports I2C and all code is present in a single file stmpe.c. It would be better to separate out I2C interface specific code from controller specific code. Later SPI specific code can be added in a separate file. This patch separates out I2C and controller specific code into separate files, making stmpe.c independent of I2C.
