Now most of ARM machines has the alsmot same __clk_get/put() macro So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config Now there are only 3 caese. 1) define the clk structure with clkdev macro => Need to move clk structure to proper header file arch/arm/mach-versatile/include/mach/clkdev.h arch/arm/mach-realview/include/mach/clkdev.h arch/arm/mach-vexpress/include/mach/clkdev.h arch/arm/mach-integrator/include/mach/clkdev.h 2) export the __clk_get/put function at clock.c arch/arm/mach-shmobile/include/mach/clkdev.h 3) demuxing the clk source arch/arm/mach-u300/include/mach/clkdev.h Acked-by: Viresh Kumar <viresh.kumar@st.com> Acked-by: H Hartley Sweeten <hsweeten@visionengravers.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

Until these drivers are runtime PM converted, their device power states are managed by calling custom driver hooks late in the idle/suspend path. Therefore, do not let the suspend/resume core code automatically idle these devices since they will be managed manually by the OMAP PM core very late in the idle/suspend path.

2011-07-10OMAP2+: hwmod: Follow the recommended PRCM module enable sequenceRajendra Nayak
On OMAP4, the PRCM recommended sequence for enabling a module after power-on-reset is: -1- Force clkdm to SW_WKUP -2- Enabling the clocks -3- Configure desired module mode to "enable" or "auto" -4- Wait for the desired module idle status to be FUNC -5- Program clkdm in HW_AUTO(if supported) This sequence applies to all older OMAPs' as well, however since they use autodeps, it makes sure that no clkdm is in IDLE, and hence not requiring a force SW_WKUP when a module is being enabled. OMAP4 does not need to support autodeps, because of the dyanamic dependency feature, wherein the HW takes care of waking up a clockdomain from idle and hence the module, whenever an interconnect access happens to the given module. Implementing the sequence for OMAP4 requires the clockdomain handling that is currently done in clock framework to be done as part of hwmod framework since the step -4- above to "Wait for the desired module idle status to be FUNC" is done as part of hwmod framework.

2011-07-10OMAP2+: clock: allow per-SoC clock init code to prevent clockdomain calls ↵Paul Walmsley
from clock code The OMAP2/3 clock code was written to notify the clockdomain code when the first clock in a clockdomain is enabled and when the last enabled clock in a clockdomain is disabled. OMAP4 requires a different approach: the hwmod code needs to signal the clockdomain code when to force-enable and auto-idle a clockdomain during the IP block enable process. The current conjecture is that once that hwmod sequence is implemented, it will no longer be necessary for the clock code to call into the clockdomain code for "optional clocks" on OMAP4. Add a static flag to the OMAP2+ clock code, clkdm_control, that by default preserves the OMAP2/3 behavior. Also add a function, omap2_clk_disable_clkdm_control(), intended to be called from OMAP4 and beyond clock initcalls, that disables the old behavior. Part of this patch was originally based on a patch by Rajendra Nayak <rnayak@ti.com>.

2011-07-10OMAP2+: clockdomain: Add per clkdm lock to prevent concurrent state programmingRajendra Nayak
Since the clkdm state programming is now done from within the hwmod framework (which uses a per-hwmod lock) instead of the being done from the clock framework (which used a global lock), there is now a need to have per-clkdm locking to prevent races between different hwmods/modules belonging to the same clock domain concurrently programming the clkdm state.

2011-07-10OMAP2+: PM: idle clkdms only if already in idleRajendra Nayak
The omap_set_pwrdm_state function forces clockdomains to idle, without checking the existing idle state programmed, instead based solely on the HW capability of the clockdomain to support idle. This is wrong and the clockdomains should be idled post a state_switch *only* if idle transitions on the clockdomain were already enabled.

2011-07-10OMAP2+: clockdomain: add clkdm_in_hwsup()Paul Walmsley
Add a new function, clkdm_in_hwsup(), that returns true if a clockdomain is configured for hardware-supervised idle. It does not actually read the hardware; rather, it checks an internal flag in the struct clockdomain, which is changed when the clockdomain is switched in and out of hardware-supervised idle. This should be safe, since all changes to the idle mode should pass through the clockdomain code. Based on a set of patches by Rajendra Nayak <rnayak@ti.com> which do the same thing by checking the hardware bits. This approach should be faster and more compact.

Take advantage of the explicit modulemode control to fix the way parents clocks are managed. A module must be disabled before any parents are disabled. That programming model was not possible with the previous implementation that was considering a modulemode as a leaf clock node managed by the clock fmwk.

Add a new field to provide the mode supported by the module. The mode will control the way mandatory clocks are managed by the PRCM. 0 : Module is temporarily disabled by SW. OCP access to module are stalled. Can be used to change timing parameter of GPMC module. 1 : Module is managed automatically by HW according to clock domain transition. A clock domain sleep transition put module into idle. A wakeup domain transition put it back into function. If CLKTRCTRL=3, any OCP access to module is always granted. Module clocks may be gated according to the clock domain state. 2 : Module is explicitly enabled. Interface clock (if not used for functions) may be gated according to the clock domain state. Functional clocks are guarantied to stay present. As long as in this configuration, power domain sleep transition cannot happen. Some modules will have a modulemode initialized at 1 (HWCTRL) by default. This is the case for interconnect and simple module like GPIO, WDT, MAILBOX.

2011-07-10OMAP4: hwmod data: Add clock domain attributeBenoit Cousson
In OMAP PRCM terminology, the clock domain is defined as a group of IPs that share some clocks and most of the time an interface clock. Every IP does belong to a clockdomain. For the moment the clock domain attribute is affected to a clock node. The issue with that approach, is that a clock might or not belong to a clock domain. Moreover during module transition, it is up to a module to handle properly the clock domain state and not to a clock node. Create a clkdm_name attribute to provide this information per hwmod. Populate this attribute for every OMAP4 hwmod entries. Future cleanup series with remove that information from the OMAP4 clock when it is relevant.

2011-07-10I2C: OMAP2+: Set hwmod flags to only allow 16-bit accesses to i2cAndy Green
Peter Maydell noticed when running under QEMU he was getting errors reporting 32-bit access to I2C peripheral unit registers that are documented to be 8 or 16-bit only[1][2] The I2C driver is blameless as it wraps its accesses in a function using __raw_writew and __raw_readw, it turned out it is the hwmod stuff. However the hwmod code already has a flag to force a perhipheral unit to only be accessed using 16-bit operations. This patch applies the 16-bit only flag to the 2430, OMAP3xxx and OMAP44xx hwmod structs. 2420 was already correctly marked up as 16-bit. The 2430 change will need testing by TI as arranged in the comments to the previous patch version. When the 16-bit flag is or-ed with other flags, it is placed first as requested in comments.

2011-07-10OMAP4: hwmod data: Change DSS main_clk schemeTomi Valkeinen
Currently using pm_runtime with DSS requires the DSS driver to enable the DSS functional clock before calling pm_runtime_get(). That makes it impossible to use pm_runtime in DSS as it is meant to be used, with pm_runtime callbacks. This patch changes the hwmod database for OMAP4 so that enabling the hwmod via pm_runtime will also enable the DSS functional clock, allowing us to use pm_runtime properly in DSS driver. The DSS HWMOD side is not really correct, not before nor after this patch, and getting DSS to retention will probably not work currently. However, it is not supported in the mainline kernel anyway, so this won't break anything. So this patch allows us to write the pm_runtime adaptation for the DSS driver the way it should be done, and the HWMOD/PM side can be fixed later.

2011-07-10OMAP4: powerdomain data: Remove unsupported MPU powerdomain stateSantosh Shilimkar
On OMAP4430 devices, because of boot ROM code bug, MPU OFF state can't be attempted independently. When coming out of MPU OFF state, ROM code disables the clocks of IVAHD, TESLA which is not desirable. Hence the MPU OFF state is not usable on OMAP4430 devices. OMAP4460 onwards, MPU OFF state will be descoped completely because the DDR firewall falls in MPU power domain. When the MPU hit OFF state, DDR won't be accessible for other initiators. The deepest state supported is open switch retention (OSWR) just like CORE and PER PD on OMAP4430. So in summary MPU power domain OFF state is not supported on OMAP4 and onwards designs. Thanks to new PRCM design, device off mode can still be achieved with power domains hitting OSWR state.

2011-07-10OMAP4: clock data: Keep GPMC clocks always enabled and hardware managedSantosh Shilimkar
On OMAP4, CPU accesses on unmapped addresses are redirected to GPMC by L3 interconnect. Because of CPU speculative nature, such accesses are possible which can lead to indirect access to GPMC and if it's clock is not running, it can result in hang/abort on the platform. Above makes access to GPMC unpredictable during the execution, so it's module mode needs to be kept under hardware control instead of software control. Since the auto gating is supported for GPMC, there isn't any power impact because of this change. The issue was un-covered with security middleware running along with HLOS. In this case GPMC had a valid MMU descriptor on secure side where as HLOS didn't map the GMPC because it isn't being used.

2011-07-10OMAP4: clock data: Remove UNIPRO clock nodesJon Hunter
UNIPRO was removed from OMAP4 devices from ES2.0 onwards. Since this IP was anyway non-functional and not supported, it is best to remove it completely.

McASP2, 3 and MMC6 modules are not present in the OMAP4 family. Remove the fclk and the clksel related to these nodes. Rename the references that were potentially re-used in order nodes. Remove related macros in prcm header files. Update TI copyright date.

2011-07-10OMAP4: clockdomain data: Fix data order and wrong nameBenoit Cousson
MPUSS was renamed MPU and L3_D2D D2D. The rename will slightly change the order of the structure and thus generate some structures moves. Add a comment and remove a comma.

2011-07-10OMAP4: cm: Remove RESTORE macros to avoid access from SWBenoit Cousson
The restore part of the CM is an alias of some regular registers used only during the SAR restore to facilate the dma to write a contiguous set of registers. The registers should never be used by the SW, only the original register have to be used. Remove them from cmX_44xx.h files to avoid anybody to use them by mistake.

2011-07-10OMAP4: clock data: Fix max mult and div for USB DPLLBenoit Cousson
The DPLL USB can generate higher speed (x2) than the regular ones. The max multiplication value is then twice the previous value. Fix both max_mult and max_div with that correct values. Change the max_div variable type to u16 to allow storing up to 256. Replace as well the define with the value to avoid unneeded indirection and provide a better readability. Remove the defines that become useless.
