2013-04-04clk: tegra: defer application of init tableStephen Warren
The Tegra clock driver is initialized during the ARM machine descriptor's .init_irq() hook. It can't be initialized earlier, since dynamic memory usage is required. It can't be initialized later, since the .init_timer() hook needs the clocks initialized. However, at this time, udelay() doesn't work. The Tegra clock initialization table may enable some PLLs. Enabling a PLL may require usage of udelay(). Hence, this can't happen right when the clock driver is initialized. To solve this, separate the clock driver initialization from the clock table processing, so they can execute at separate times. Signed-off-by: Stephen Warren <swarren@nvidia.com>

2013-04-02clk: allow reentrant calls into the clk frameworkMike Turquette
Reentrancy into the clock framework is necessary for clock operations that result in nested calls to the clk api. A common example is a clock that is prepared via an i2c transaction, such as a clock inside of a discrete audio chip or a power management IC. The i2c subsystem itself will use the clk api resulting in a deadlock: clk_prepare(audio_clk) i2c_transfer(..) clk_prepare(i2c_controller_clk) The ability to reenter the clock framework prevents this deadlock. Other use cases exist such as allowing .set_rate callbacks to call clk_set_parent to achieve the best rate, or to save power in certain configurations. Yet another example is performing pinctrl operations from a clk_ops callback. Calls into the pinctrl subsystem may call clk_{un}prepare on an unrelated clock. Allowing for nested calls to reenter the clock framework enables both of these use cases. Reentrancy is implemented by two global pointers that track the owner currently holding a global lock. One pointer tracks the owner during sleepable, mutex-protected operations and the other one tracks the owner during non-interruptible, spinlock-protected operations. When the clk framework is entered we try to hold the global lock. If it is held we compare the current task against the current owner; a match implies a nested call and we reenter. If the values do not match then we block on the lock until it is released.

2013-03-27clk: sunxi: rename compatible stringsEmilio López
During the introduction of the Allwinner SoC platforms, sunxi was initially meant as a generic name for all the variants of the Allwinner SoC. It was ok at the time of the support of only the A10 and A13 that look pretty much the same; but it's beginning to be troublesome with the future addition of the Allwinner A31 (sun6i) that is quite different, and would introduce some weird logic, where sunxi would actually mean in some case sun4i and sun5i but without sun6i... Moreover, it makes the compatible strings naming scheme not consistent with other architectures, where usually for this kind of compability, we just use the oldest SoC name that has this IP, so let's do just this.

2013-03-26clk: Add composite clock typePrashant Gaikwad
Not all clocks are required to be decomposed into basic clock types but at the same time want to use the functionality provided by these basic clock types instead of duplicating. For example, Tegra SoC has ~100 clocks which can be decomposed into Mux -> Div -> Gate clock types making the clock count to ~300. Also, parent change operation can not be performed on gate clock which forces to use mux clock in driver if want to change the parent. Instead aggregate the basic clock types functionality into one clock and just use this clock for all operations. This clock type re-uses the functionality of basic clock types and not limited to basic clock types but any hardware-specific implementation.

2013-03-23KMS: fix EDID detailed timing frame rateTorsten Duwe
When KMS has parsed an EDID "detailed timing", it leaves the frame rate zeroed. Consecutive (debug-) output of that mode thus yields 0 for vsync. This simple fix also speeds up future invocations of drm_mode_vrefresh(). While it is debatable whether this qualifies as a -stable fix I'd apply it for consistency's sake; drm_helper_probe_single_connector_modes() does the same thing already for all probed modes.
