git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu IOMMU fixes for Linux 3.3-rc5 All the fixes are for the OMAP IOMMU driver. The first patch is the biggest one. It fixes the calls of the function omap_find_iovm_area() in the omap-iommu-debug module which expects a 'struct device' parameter since commit fabdbca instead of an omap_iommu handle. The omap-iommu-debug code still passed the handle to the function which caused a crash. The second patch fixes a NULL pointer dereference in the OMAP code and the third patch makes sure that the omap-iommu is initialized before the omap-isp driver, which relies on the iommu. The last patch is only a workaround until defered probing is implemented. * tag 'iommu-fixes-v3.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp iommu/omap: fix NULL pointer dereference iommu/omap: fix erroneous omap-iommu-debug API calls

2012-02-20ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a moduleTony Lindgren2-1/+7
On some omaps twl4030_gpio has a callback to try to initialize the MMC controller. If twl4030_gpio is compiled as a module, bad things can happen because the callback function starts calling functions that are supposed to be marked __init: Kernel panic - not syncing: Attempted to kill the idle task! twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules gpiochip_add: registered GPIOs 192 to 209 on device: twl4030 Unable to handle kernel paging request at virtual address b82a4c74 ... Additionally if this does not fail, warnings are produced about trying to register the MMC multiple times. Fix this by removing __init from omap_mux_get_by_name, and add checks if omap2_hsmmc_init() is getting called more than once. Note that this will get fixed properly later on by splitting omap2_hsmmc_init into two functions.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc These are the bug fixes that have accumulated since 3.3-rc3 in arm-soc. The majority of them are regression fixes for stuff that broke during the merge 3.3 window. The notable ones are: * The at91 ata drivers both broke because of an earlier cleanup patch that some other patches were based on. Jean-Christophe decided to remove the legacy at91_ide driver and fix the new-style at91-pata driver while keeping the cleanup patch. I almost rejected the patches for being too late and too big but in the end decided to accept them because they fix a regression. * A patch fixing build breakage from the sysdev-to-device conversion colliding with other changes touches a number of mach-s3c files. * b0654037 "ARM: orion: Fix Orion5x GPIO regression from MPP cleanup" is a mechanical change that unfortunately touches a lot of lines that should up in the diffstat. * tag 'fixes-3.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (28 commits) ARM: at91: drop ide driver in favor of the pata one pata/at91: use newly introduced SMC accessors ARM: at91: add accessor to manage SMC ARM: at91:rtc/rtc-at91sam9: ioremap register bank ARM: at91: USB AT91 gadget registration for module ep93xx: fix build of vision_ep93xx.c ARM: OMAP2xxx: PM: fix OMAP2xxx-specific UART idle bug in v3.3 ARM: orion: Fix USB phy for orion5x.

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

2012-02-13ARM: omap: resolve nebulous 'Error setting wl12xx data'Russell King4-15/+33
It's useful to print the error code when a called function fails so a diagnosis of why it failed is possible. In this case, it fails because we try to register some data for the wl12xx driver, but as the driver is not configured, a stub function is used which simply returns -ENOSYS. Let's do the simple thing for -rc and print the error code. Also, the return code from platform_register_device() at each of these sites was not being checked. Add some checking, and again print the error code. This should be fixed properly for the next merge window so we don't issue error messages merely because a driver is not configured.

Found by review. omap4_sdp4430_wifi_mux_init() is called by an __init marked function, and only calls omap_mux_init_gpio() and omap_mux_init_signal() which are both also an __init marked functions. The only reason this doesn't issue a warning is because the compiler inlines omap4_sdp4430_wifi_mux_init() into omap4_sdp4430_wifi_init(). So, lets add the __init annotation to ensure this remains safe should the compiler choose not to inline.

This doesn't help identify what the problem is. Fix this message to be more informative: omap_vc_i2c_init: I2C config for vdd_iva does not match other channels (0). omap_vc_i2c_init: I2C config for vdd_mpu does not match other channels (0). This allows us to identify which voltage domains have a problem, and what the I2C configuration state (a boolean, i2c_high_speed) setting being used actually is.

This breaks the serial port now that the UART driver's clock behavior can be controlled via the PM autosuspend timeout. To fix, remove the special-case idle handling for the UARTs in the OMAP2420/2430 PM idle code added by commit 4af4016c53f52b26461b8030211f8427a58fa5ed ("OMAP3: PM: UART: disable clocks when idle and off-mode support").

2012-02-09tty: serial: OMAP: block idle while the UART is transferring data in PIO modePaul Walmsley1-4/+4
Prevent OMAP UARTs from going idle while they are still transferring data in PIO mode. This works around an oversight in the OMAP UART hardware present in OMAP34xx and earlier: an idle UART won't send a wakeup when the TX FIFO threshold is reached. This causes long delays during data transmission when the MPU powerdomain enters a low-power mode. The MPU interrupt controller is not able to respond to interrupts when it's in a low-power state, so the TX buffer is not refilled until another wakeup event occurs. This fix changes the erratum i291 DMA idle workaround. Rather than toggling between force-idle and no-idle, it will toggle between smart-idle and no-idle. The important part of the workaround is the no-idle part, so this shouldn't result in any change in behavior. This fix should work on all OMAP UARTs. Future patches intended for the 3.4 merge window will make this workaround conditional on a "feature" flag, and will use the OMAP36xx+ TX event wakeup support. Thanks to Kevin Hilman <khilman@ti.com> for mentioning the erratum i291 workaround, which led to the development of this approach.

hsmmc23_before_set_reg() can set MMCSDIO2ADPCLKISEL bit, which enables internal clock for MMC2. Currently this function is also called by code handling MMC3, and if .internal_clock is set in platform data (by default it currently is), it will set MMCSDIO2ADPCLKISEL for MMC2 instead of MMC3 (MMC3 doesn't have such bit so nothing actually needs to be done). This breaks 2nd SD slot on pandora. Fix this by changing hsmmc23_before_set_reg() to only handle MMC2.

2012-01-26OMAPDSS: HDMI: PHY burnout fixTomi Valkeinen2-0/+10
A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board if the HDMI PHY is kept powered on when the cable is not connected. This patch solves the problem by adding hot-plug-detection into the HDMI IP driver. This is not a real HPD support in the sense that nobody else than the IP driver gets to know about the HPD events, but is only meant to fix the HW bug. The strategy is simple: If the display device is turned off by the user, the PHY power is set to OFF. When the display device is turned on by the user, the PHY power is set either to LDOON or TXON, depending on whether the HDMI cable is connected. The reason to avoid PHY OFF when the display device is on, but the cable is disconnected, is that when the PHY is turned OFF, the HDMI IP is not "ticking" and thus the DISPC does not receive pixel clock from the HDMI IP. This would, for example, prevent any VSYNCs from happening, and would thus affect the users of omapdss. By using LDOON when the cable is disconnected we'll avoid the HW bug, but keep the HDMI working as usual from the user's point of view. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
