2013-05-18Merge branch 'devm_no_resource_check' of ↵Linus Torvalds2-10/+0
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull devm usage cleanup from Wolfram Sang: "Lately, I have been experimenting how to improve the devm interface to make writing device drivers easier and less error prone while also getting rid of its subtle issues. I think it has more potential but still needs work and definately conistency, especiall in its usage. The first thing I come up with is a low hanging fruit regarding devm_ioremap_resouce(). This function already checks if the passed resource is valid and gives an error message if not. So, we can remove similar checks from the drivers and get rid of a bit of code and a number of inconsistent error strings. This series only removes the unneeded check iff devm_ioremap_resource follows platform_get_resource directly. The previous version tried to shuffle code if needed, too, what lead to an embarrasing bug. It turned out to me that shuffling code for all cases found will make the automated script too complex, so I am unsure if an automated cleanup is the proper tool for this case. Removing the easy stuff seems worthwhile to me, though. Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs."

2013-05-13ARM: 7720/1: ARM v6/v7 cmpxchg64 shouldn't clear upper 32 bits of the ↵Jaccon Bastiaansen1-4/+4
old/new value The implementation of cmpxchg64() for the ARM v6 and v7 architecture casts parameter 2 and 3 (the old and new 64bit values) to an unsigned long before calling the atomic_cmpxchg64() function. This clears the top 32 bits of the old and new values, resulting in the wrong values being compare-exchanged. Luckily, this only appears to be used for 64-bit sched_clock, which we don't (yet) have on ARM. This bug was introduced by commit 3e0f5a15f500 ("ARM: 7404/1: cmpxchg64: use atomic64 and local64 routines for cmpxchg64").

2013-05-09ARM: OMAP2+: Remove bogus IS_ERR_OR_NULL checking from id.cTony Lindgren1-3/+2
Commit 6770b211 (ARM: OMAP2+: Export SoC information to userspace) had some broken return value handling as noted by Russell King: + soc_dev = soc_device_register(soc_dev_attr); + if (IS_ERR_OR_NULL(soc_dev)) { + kfree(soc_dev_attr); + return; + } + + parent = soc_device_to_device(soc_dev); + if (!IS_ERR_OR_NULL(parent)) + device_create_file(parent, &omap_soc_attr); This is nonsense. For the first, IS_ERR() is sufficient. For the second, tell me what error checking is required in the return value of this function: struct device *soc_device_to_device(struct soc_device *soc_dev) { return &soc_dev->dev; } when you've already determined that the passed soc_dev is a valid pointer. If you read the comments against the prototype: /** * soc_device_to_device - helper function to fetch struct device * @soc: Previously registered SoC device container */ struct device *soc_device_to_device(struct soc_device *soc); if "soc" is valid, it means the "previously registered SoC device container" must have succeeded and that can only happen if the struct device has been registered. Ergo, there will always be a valid struct device pointer for any registered SoC device container. Therefore, if soc_device_register() succeeds, then the return value from soc_device_to_device() will always be valid and no error checking of it is required. Simples. The rule as ever applies here: get to know the APIs your using and don't fumble around in the dark hoping that you'll get this stuff right. Fix it as noted by Russell.

2013-05-08ARM: OMAP2+: omap_device: use late_initcall_syncKevin Hilman2-1/+2
If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled as a module, the kernel boot hangs early as the clocks for serial port are cut while earlyprintk still uses the port. The problem is a race between the late_initcall for omap_device (which idles devices that have no drivers) and the late_initcall in kernel/printk.c which turns off the earlyconsole. Any printks that happen between this omap_device late initcall and the earlyconsole late initcall will crash when accessing the UART. The fix is to ensure the omap_device initcall happens after the earlyconsole initcall.

2013-05-08ARM: OMAP: RX-51: change probe order of touchscreen and panel SPI devicesAaro Koskinen1-2/+2
Commit 9fdca9df (spi: omap2-mcspi: convert to module_platform_driver) broke the SPI display/panel driver probe on RX-51/N900. The exact cause is not fully understood, but it seems to be related to the probe order. SPI communication to the panel driver (spi1.2) fails unless the touchscreen (spi1.0) has been probed/initialized before. When the omap2-mcspi driver was converted to a platform driver, it resulted in that the devices are probed immediately after the board registers them in the order they are listed in the board file. Fix the issue by moving the touchscreen before the panel in the SPI device list. The patch fixes the following failure: [ 1.260955] acx565akm spi1.2: invalid display ID [ 1.265899] panel-acx565akm display0: acx_panel_probe panel detect error [ 1.273071] omapdss CORE error: driver probe failed: -19 Tested-by: Sebastian Reichel <sre@debian.org> Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Cc: Pali Rohár <pali.rohar@gmail.com> Cc: Joni Lapilainen <joni.lapilainen@gmail.com> Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Felipe Balbi <balbi@ti.com> Cc: stable@vger.kernel.org Signed-off-by: Tony Lindgren <tony@atomide.com>

On Beagle xM Rev. Ax/Bx, the USB power enable GPIO logic is reversed when compared to other revisions i.e. it is active high instead of active low. Use the beagle_config.usb_pwr_level flag correctly so that the power regulator can be configured at runtime.

2013-05-08ARM: dts: OMAP4: Fix ethernet IRQ for OMAP4 boardsJon Hunter2-2/+2
Commit ff5c9059 (ARM: dts: OMAP3+: Correct gpio #interrupts-cells property) updated the number of interrupt cells required for configuring gpios as interrupts for other devices (such as ethernet controllers). This update allowed the interrupt type (edge, level, etc) to be configured via device-tree (as described in the Documentation/devicetree/bindings/gpio/gpio-omap.txt). This broke ethernet support on the OMAP4 SDP board that defines a gpio as the ethernet IRQ because the interrupt type (level, edge, etc) was not getting configured correctly. This board use the ks8851 ethernet chip which has an active low interrupt. Fix this by defining the gpio interrupt as active-low in the device-tree binding. Please note that the OMAP4-VAR-SOM also uses the same ethernet controller and it is expected it will have the same problem. So the same fix is also applied to this board.

2013-05-07arm: fix mismerge of arch/arm/mach-omap2/timer.cLinus Torvalds1-0/+4
I badly screwed up the merge in commit 6fa52ed33bea ("Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/.../arm-soc") by incorrectly taking the arch/arm/mach-omap2/* data fully from the merge target because the 'drivers-for-linus' branch seemed to be a proper superset of the duplicate ARM commits. That was bogus: commit ff931c821bab ("ARM: OMAP: clocks: Delay clk inits atleast until slab is initialized") only existed in head, and the changes to arch/arm/mach-omap2/timer.c from that commit got list. Re-doing the merge more carefully, I do think this part was the only thing I screwed up. Knock wood.

As a result, it should become really easy to add full multiplatform exynos support in 3.11, although we don't yet enable it for 3.10. The changes were not included in the earlier multiplatform series in order to avoid clashes with the other Exynos updates.

Remarkably, this adds support for three new SoCs: r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is for pinctrl (using the new subsystem) and for clocks (not yet using the common clock subsystem). The latter will have to get converted in one of the upcoming releases, but shmobile is not ready for that yet. The series also contains Renesas shmobile board changes, adding one board file for each of the three new SoCs. These boards are using a mix of classic and device-tree based probing, as there is still a lot of infrastructure in shmobile that has not been converted to DT yet.
