| | * | | | OMAP4: PM: Define additional registers for ES2Rajendra Nayak2010-09-27

Replace as well the BITFIELD macro with the shift operator in order to be consistent with the previous OMAP2 & 3 format. Sort the register list in comments in order to have a consistent register order and avoid futur change during code generation.

| | * | | | OMAP4: clock: Add optional clock nodesBenoit Cousson2010-09-27

In order to allow that we have to create artificial clock nodes that represent this clock inputs in the IP. Notes: - Temporary use OMAP3 names for GPIO optional clocks until the GPIO hwmod convertion is done. It will enforce the usage of OMAP4 names as the reference. - Temporary use OMAP3 names for TIMER main clock (gptX_fck) until TIMER hwmod convertion is done. During that convertion, the new name will have to be used.

| | * | | | OMAP4: clock: Fix clock names and align with hwmod namesBenoit Cousson2010-09-27

Please not that due to the fact that nodes are sorted by name, the name change will introduce a quite ugly diff a little bit hard to follow. Timers clock con_id is still using the old gptX_fck name until the gptimer driver is updated to omap_device framework. Timers entries in hwmods DB are still disabled until the migration if timer to platform_driver + omap_hwmod.

OMAP specific runtime PM methods are registered with the as custom methods on the platform_bus. In order to determine if a device is an omap_device, its parent device is checked. All omap_devices have a new 'omap_device_parent_ device as their parent device, so checking for this parent is used to check for valid omap_devices. If a device is an omap_device, then the appropriate omap_device functions are called for it. If not, only the generic runtime PM functions are called. Device driver's ->runtime_idle() hook is called when the runtime PM usecount reaches zero for that device. Driver's ->runtime_suspend() hooks are called just before the device is disabled (via omap_device_idle()), and device driver ->runtime_resume() hooks are called just after device has been enabled (via omap_device_enable().)

This fixes a major bug where critical sleep dependencies added by the hwmod code are cleared during late PM init. As a side benefit, the _init_{wk,sleep}dep_usecount() functions are no longer needed, so remove them.

This keeps the core, interrupts-disabled idle path streamlined and independent of any device-specific handling, and also allows CPUidle to do the checking only for certain C-states as needed. This patch has the device checks in place for all states with the CHECK_BM flag, namely all states >= C2. This patch was inspired by a similar patch written by Tero Kristo as part of a larger series to add INACTIVE state support. NOTE: This is a baby-step towards decoupling device idle (or system idle) from CPU idle. Eventually, CPUidle should only manage the CPU, and device/system idle should be managed elsewhere.

Add a HWMOD_CONTROL_OPT_CLKS_IN_RESET flag to force all optional clocks to be enabled before reset. Disabled them once the reset is done. TODO: For the moment it is very hard to understand from the HW spec, which optional clock is needed and which one is not. So the current approach will enable all the optional clocks. Paul proposed a much finer approach that will allow to tag only the needed clock in the optional clock table. This might be doable as soon as we have a clear understanding of these dependencies.

Starting in OMAP4, some IPs does not have SYSSTATUS register and instead use the SYSC softreset bit to provide the status. Other cases might exist: - Some IPs like McBSP does have a softreset control but no reset status. - Some IPs that represent subsystem, like the DSS, can contains a reset status without softreset control. The status is the aggregation of all the sub modules reset status. - Add a new flag (SYSC_HAS_RESET_STATUS) to identify the new programming model and replace the previous SYSS_MISSING, that was used to flag IP with softreset control but without the SYSSTATUS register, with a specific SYSS_HAS_RESET_STATUS flag. - MCSPI and MMC contains both programming models, so the legacy one will be prevented by removing the syss offset field that become useless.

This is different of the softreset used for local IP reset from the SYSCONFIG register. The granularity can be much finer than orginal HWMOD, for ex, the IVA hwmod contains 3 reset lines, the IPU 3 as well, the DSP 2... Since this granularity is needed by the driver, we have to ensure than one hwmod exist for each hardreset line. - Store reset lines as hwmod resources that a driver can query by name like an irq or sdma line. - Add two functions for asserting / deasserting reset lines in hwmods processor that require manual reset control. - Add one functions to get the current reset state. - If an hwmod contains only one line, an automatic assertion / de-assertion is done. -> de-assert the hardreset line only during enable from disable transition -> assert the hardreset line only during shutdown Note: The hwmods with hardreset line and HWMOD_INIT_NO_RESET flag must be kept in INITIALIZED state. They can be properly enabled only if the hardreset line is de-asserted before.
