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.

2011-07-10OMAP4: hwmod: Introduce the module control in hwmod controlBenoit Cousson
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. This was leading to bad crash upon disable when the parent clock was gated before the module completed its transition to idle.

2011-07-10OMAP4: hwmod data: Add modulemode entry in omap_hwmod structureBenoit Cousson
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.

2011-07-10OMAP: hwmod: Wait the idle status to be disabledBenoit Cousson
It is mandatory to wait for a module to be in disabled state before potentially disabling source clock or re-asserting a reset. omap_hwmod_idle and omap_hwmod_shutdown does not wait for the module to be fully idle. Add a cm_xxx accessor to wait the clkctrl idle status to be disabled. Fix hwmod_[idle|shutdown] to use this API. Based on Rajendra's initial patch. Please note that most interconnects hwmod will return one timeout because it is impossible for them to be in idle since the processor is accessing the registers though the interconnect.

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.

On OMAP4 the auxclk nodes (part of SCRM) support both divider as well as parent selection.

2011-07-10OMAP: hwmod: fix the i2c-reset timeout during bootupAvinash.H.M
The sequence of _ocp_softreset doesn't work for i2c. The i2c module has a special sequence to reset the module. The sequence is - Disable the I2C. - Write to SOFTRESET bit. - Enable the I2C. - Poll on the RESETDONE bit. The sequence is implemented as a function and the i2c_class is updated with the correct 'reset' pointer. omap_hwmod_softreset function is implemented which triggers the softreset by writing into sysconfig register. On following this sequence, i2c module resets properly and timeouts are not seen.
