Add mmu hwmod data for iva and isp. Due to compatibility an ifdef CONFIG_OMAP_IOMMU_IVA2 needs to be propagated (previously on iommu resource info) to hwmod data in OMAP3, so users of iommu and tidspbridge can avoid issues of two modules managing mmu data/irqs/resets; this until tidspbridge can be migrated to iommu framework.

Made *ocp2scp_usb_phy_phy_48m* as the main_clk for ocp2scp. Since this ocp2scp module does not have any fck but does have a single opt_clock, it is added as the main_clk for ocp2scp. Also removed phy_48m as the optional clock since it is now made as the main clock. By this the driver need not enable/disable phy_48m clk separately and runtime_get/runtime_put will take care of that.

For a reset sequence to complete cleanly, a module needs its associated clocks to be enabled, otherwise the timeout check in prcm code can print a false failure (failed to hardreset) that occurs because the clocks aren't powered ON and the status bit checked can't transition without them.

Some IP blocks might not be using/controlling more than one reset line, this check loosens the restriction to fully use hwmod framework for those drivers. E.g.: ipu has reset lines: mmu_cache, cpu0 and cpu1. - As of now cpu1 is not used and hence (with previous check) the IP block isn't fully enabled by hwmod code. - Usually ipu and dsp processors configure their mmu module first and then enable the processors, this involves: * Deasserting mmu reset line, and enabling the module. * Deasserting cpu0 reset line, and enabling the processor. The ones portrayed in this example are controlled through rproc_fw_boot in drivers/remoteproc/remoteproc_core.c While at it, prevent _omap4_module_disable if all the hardreset lines on an IP block are not under reset. This will allow the driver to: a. Deassert the reset line. b. Enable the hwmod through runtime PM default callbacks. c. Do its usecase. d. Disable hwmod through runtime PM. e. Assert the reset line.

On OMAP4 most modules/hwmods support module level context status. On OMAP3 and earlier, we relied on the power domain level context status. Identify all modules that don't support 'context_offs' by adding a flag bit, HWMOD_OMAP4_NO_CONTEXT_LOSS_BIT. Rest have a valid 'context_offs' populated in .prcm structure already.

Currently hwmod only provides the offset for the context lose register, and if we attempt to share the same register between two or more hwmods, the resulting context loss counts get wrong. Thus, we need a way to specify which bits are used for the context loss information for each. This is accomplished by adding a new field to the omap4 prcm struct, 'lostcontext_mask', which specifies a bit-mask to use for filtering the register. Mark the affected hwmods appropriately. 'l4_abe' hwmod uses the LOSTMEM_AESSMEM bit of RM_ABE_AESS_CONTEXT register, as l4_abe doesn't have its own dedicated register for this purpose. This register is shared with 'aess' hwmod, thus both hwmods must also specify which bits of the register are used for them. This patch only adds the hwmod data, but a future patch should add code support such that only the specified bits are read and cleared by the context lose counter update code. If a hwmod doesn't specify 'lostcontext_mask' (default behavior), the whole contents of the context register should be used without any filtering.

On OMAP4, there is no support to read previous logic state or previous memory state achieved when a power domain transitions to RET. Instead there are module level context registers. In order to support the powerdomain level logic/mem_off_counters on OMAP4, instead use the previous power state achieved (RET) and the *programmed* logic/mem RET state to derive if a powerdomain lost logic or did not. If the powerdomain is programmed to enter RET state and lose logic in RET state, knowing that the powerdomain entered RET is good enough to derive that the logic was lost as well, in such cases.

The decision was made a few months ago to allow struct omap_hwmod records and struct clk records to omit clockdomain information if the clockdomain is not software-controllable. See for example commit 868c157d ("ARM: OMAP2+: hwmod: remove prm_clkdm, cm_clkdm; allow hwmods to have no clockdomain"). So convert an existing pr_warning() to a pr_debug() (regarding missing clockdomains in clocks), and add a pr_debug() for missing hwmod clockdomains. It's still useful to enable these messages for debugging, since missing clockdomains can cause hard-to-debug problems with power management; see for example commit 6c4a057b ("ARM: OMAP4: clock data: Force a DPLL clkdm/pwrdm ON before a relock").

We're no longer requiring struct omap_hwmod records to contain a clockdomain. So we shouldn't return -EINVAL any more from _omap4_wait_target_disable() or _omap4_wait_target_ready() if there's no clockdomain defined, since that just gets passed back to the caller. This can result in pointless warnings under the relaxed data format. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Benoît Cousson <b-cousson@ti.com>

The new common clk framework includes basic definitions for mux and divider clocks. These definitions depend on shift and width values instead of the pre-computed masks that the OMAP/AM33XX clk framework has traditionally used when accessing the register to control the mux or divisor. To ease this transition the masks are left intact and the width field is simply added alongside the shift and mask data.

While we move to Common Clk Framework (CCF), direct deferencing of struct clk wouldn't be possible anymore. Hence get rid of all such instances in the current clock code and use macros/helpers similar to the ones that are provided by CCF.

Moving to Common clk framework for OMAP would mean we no longer use internal lookup mechanism like omap_clk_get_by_name(). get rid of all its usage mostly from hwmod and omap_device code. Moving to clk_get() also means the respective platforms need the clkdev tables updated with an entry for all clocks used by hwmod to have clock name same as the alias.

As part of Common Clk Framework (CCF) the clk_enable() operation was split into a clk_prepare() which could sleep, and a clk_enable() which should never sleep. Similarly the clk_disable() was split into clk_disable() and clk_unprepare(). This was needed to handle complex cases where in a clk gate/ungate would require a slow and a fast part to be implemented. None of the clocks below seem to be in the 'complex' clocks category and are just simple clocks which are enabled/disabled through simple register writes. Most of the instances also seem to be called in non-atomic context which means its safe to move all of those from using a clk_enable() to clk_prepare_enable() and clk_disable() to clk_disable_unprepare(). For some others, mainly the ones handled through the hwmod framework there is a possibility that they get called in either an atomic or a non-atomic context. The way these get handled below work only as long as clk_prepare is implemented as a no-op (which is the case today) since this gets called very early at boot while most subsystems are unavailable. Hence these are marked with a *HACK* comment, which says we need to re-visit these once we start doing something meaningful with clk_prepare/clk_unprepare like doing voltage scaling or something that involves i2c. This is in preparation of OMAP moving to CCF. Based on initial changes from Mike Turquette. Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

For OMAP4, the dmtimers are located in the Wake-up, ABE and Peripheral (PER) power domains. Hence, when the dmtimer is configured to use the "timer_sys_ck" as its functional clock the actual clock used is different depending on whether the clock is in the Wake-up, ABE or PER domain. So when we look-up the dmtimer's "timer_sys_ck" we need to specify the timer device name as well as clock alias to find the right clock. Currently, the device names for the timers have the format "omap_timer.X" where X is the timer instance number. When using to device tree, the format of the device name created by device-tree is different and has the format "<reg-address>.<device-name>" (this is assuming that the device-tree "reg" property is specified). This causes the look-up for the OMAP4 "timer_sys_ck" to fail. To fix this add new timer clock alias for using device-tree. Please note that adding a 2nd set of clock aliases for the same clocks to only temporary until device-tree migration is complete. Then we can remove the legacy aliases. Hence, I have marked the legacy aliases with a "TODO" to remove them. Signed-off-by: Jon Hunter <jon-hunter@ti.com> [paul@pwsan.com: updated to apply] Signed-off-by: Paul Walmsley <paul@pwsan.com>

In commit c59b537d (ARM: OMAP2+: Simplify dmtimer clock aliases) new clock aliases were added for OMAP2+ devices. For OMAP2420, I incorrectly set the clock flag as CK_243X instead of CK_242X. This did not introduce a regression as the clock flags are not checked for OMAP2 devices. This also explains why I did not catch this when testing on OMAP2420. Fix the clock flags for these aliases for correctness. Signed-off-by: Jon Hunter <jon-hunter@ti.com>

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) broke compile for non-omap as include plat/cpu.h was added. This header was indirectly included earlier when SPARSE_IRQ was not set, but does not exist on most platforms. Fix the problem by removing the cpu_is_omap usage that should not exist in drivers at all. We can do this by adding proper clock aliases for the twl-core.c drivers, and drop separate handling for cases when clock framework is not available as the behaviour will stay the same. Note that we need to add a platform device to avoid using the i2c provided names that may be different on various omaps.
