| | * ARM: OMAP: convert omap_device_build() and callers to __initKevin Hilman2012-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building omap_devices should only be done at init time, and since omap_device_build() is using early_platform calls which are also __init, this ensures that omap_device isn't trying to use functions that disappear.

| | * ARM: OMAP2+: Mark omap_hsmmc_init and omap_mux related functions as __initTony Lindgren2012-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that omap hsmmc init is split into two functions, it's safe to mark omap_hsmmc_init and omap_mux related functions to __init. This basically reverts the following fixes for the case where TWL was compiled as a module: a98f77b (ARM: omap: fix section mismatch warning for sdp3430_twl_gpio_setup()) 8930b4e (ARM: omap: fix section mismatch warnings in mux.c caused by hsmmc.c) Additionally it fixes up the remaining section warnings for all callers of omap_mux functions.

| | * ARM: OMAP2+: Split omap2_hsmmc_init() to properly support I2C GPIO pinsTony Lindgren2012-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Otherwise omap_device_build() and omap_mux related functions can't be marked as __init when twl is build as a module. If a board is using GPIO pins or regulators configured by an external chip, such as TWL PMIC on I2C bus, the board must mark those MMC controllers as deferred. Additionally both omap_hsmmc_init() and omap_hsmmc_late_init() must be called by the board. For MMC controllers using internal GPIO pins for card detect and regulators the slots don't need to be marked deferred. In this case calling omap_hsmmc_init() is sufficient. Only mark the MMC slots using gpio_cd or gpio_wd as deferred as noted by Igor Grinberg <grinberg@compulab.co.il>. Note that this patch does not change the behaviour for board-4430sdp.c board-omap4panda.c. These boards wrongly rely on the omap_hsmmc.c init function callback to configure the PMIC GPIO interrupt lines on external chip. If the PMIC interrupt lines are not configured during init, they will fail.

| | * ARM: OMAP: omap_device: Expose omap_device_{alloc, delete, register}Ohad Ben-Cohen2012-02-20

This approach allows users, which need to manipulate an archdata member of a device before it is registered, to do so. This is also useful for users who have their devices created very early so they can be used at ->reserve() time to reserve CMA memory. The immediate use case for this is to set the private iommu archdata member, which binds a device to its associated iommu controller. This way, generic code will be able to attach omap devices to their iommus, without calling any omap-specific API. With this in hand, we can further clean the existing mainline OMAP iommu driver and its mainline users, and focus on generic IOMMU approaches for future users (rpmsg/remoteproc and the upcoming generic DMA API). This patch is still considered an interim solution until DT fully materializes for omap; at that point, this functionality will be removed as DT will take care of creating the devices and configuring them correctly. Tested on OMAP4 with a generic rpmsg/remoteproc that doesn't use any omap-specific IOMMU API anymore.

| | * ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a moduleTony Lindgren2012-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Unlike most IP blocks, the I2C block requires some extra programming for this to work. This reset code is incorrectly omitted when the I2C driver is deselected. In this circumstance, the build breaks. Fix by compiling the I2C reset code unconditionally. Problem reported by Russell King <linux@arm.linux.org.uk>.

Use cpu_is_omap44xx() instead of the cpu_is_omap4430(). cpu_is_omap4430() returns 0 unconditionally. This causes that the dma_common_ch_end register variable is not configured correctly on OMAP4, not even for OMAP4430. Because of this, registers between CCFN - CCDN will be not cleard in the omap2_clear_dma function in OMAP4.

That seems to be wrong and would eventually lead to kernel crash on the CPU frequency transitions on the SOCs where the local timer doesn't exist or broken because of hardware BUG. Fix it by testing twd_evt and *__this_cpu_ptr(twd_evt). The issue was observed with v3.3-rc3 and building an OMAP2+ kernel on OMAP3 SOC which doesn't have TWD.

This is because v7_setup (which is called very early during boot) calls v7_flush_dcache_all, and the save_and_disable_irqs added by that patch ends up attempting to call into lockdep C code (trace_hardirqs_off()) when we are in no position to execute it (no stack, MMU off). Fix this by using a notrace variant of save_and_disable_irqs. The code already uses the notrace variant of restore_irqs.

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").
