* OMAP: clock: fix configuration of J-Type DPLLs to work for OMAP3 and OMAP4Jon Hunter2010-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | J-Type DPLLs have additional configuration parameters that need to be programmed when setting the multipler and divider for the DPLL. These parameters being the sigma delta divider (SD_DIV) for the DPLL and the digital controlled oscillator (DCO) to be used by the DPLL. The current code is implemented specifically to configure the OMAP3630 PER J-Type DPLL. The OMAP4430 USB DPLL is also a J-Type DPLL and so this code needs to be updated to work for both OMAP3 and OMAP4 devices and any other future devices that have J-TYPE DPLLs. For the OMAP3630 PER DPLL both the SD_DIV and DCO paramenters are used but for the OMAP4430 USB DPLL only the SD_DIV field is used. The current implementation will only program the SD_DIV and DCO fields if the DPLL has both and hence this does not work for OMAP4430. In order to make the code more generic add two new fields to the dpll_data structure for the SD_DIV field and DCO field bit-masks and only program these fields if the masks are defined for a specific DPLL. This simplifies the code and allows us to remove the flag DPLL_NO_DCO_SEL. Tested on OMAP36xx Zoom3 and OMAP4 Blaze.

* OMAP2+ clock: clean up clkt_clksel.cPaul Walmsley2010-05-20
| | | | | | | | | | | | | | | | | | | This patch cleans up arch/arm/mach-omap2/clkt_clksel.c. It: - makes several functions static that are not called outside the file; - adds documentation; - makes some code paths easier to read (hopefully), by breaking up compound statements and removing redundant checks; - converts some pr_err()s that indicate clock tree data problems into WARN()s, so they are more likely to be noticed; - and moves omap2_clk_round_rate() back into mach-omap2/clock.c, its proper home, since it is not clksel-specific.

* OMAP4: clock: Add dummy clock nodes for interface clocksSantosh Shilimkar2010-02-24
| | | | | | | | | | | | | | | | On OMAP4 platform the iclk control is completly under hardware control and no software control is available. This difference w.r.t previous OMAP's needs all the common driver accross OMAP's , cpu_is_xxxx() checks.

* OMAP2 clock: drop DELAYED_APP clock flagPaul Walmsley2010-02-24
| | | | | | | | | | | | | | | | All of the clocks that are marked with DELAYED_APP are changed as part of the virt_prcm_set OPP virtual clock. On 24xx, these clocks all need to be changed as part of a group to keep the clock tree functional - hence the need for the VALID_CONFIG bit, which is not present on later OMAPs. These clocks should not be rate-changed independently. So prevent these clocks from being changed independently by dropping their .round_rate and .set_rate function pointers. It then turns out that the DELAYED_APP clock flag is no longer useful, so drop it and the associated code and renumber the clock flags.

* OMAP3/4 clock: split into per-chip family filesPaul Walmsley2010-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | clock34xx_data.c now contains data for the OMAP34xx family, the OMAP36xx family, and the OMAP3517 family, so rename it to clock3xxx_data.c. Rename clock34xx.c to clock3xxx.c, and move the chip family-specific clock functions to clock34xx.c, clock36xx.c, or clock3517.c, as appropriate. So now "clock3xxx.*" refers to the OMAP3 superset. The main goal here is to prepare to compile chip family-specific clock functions only for kernel builds that target that chip family. To get to that point, we also need to add CONFIG_SOC_* options for those other chip families; that will be done in future patches, planned for 2.6.35. OMAP4 is also affected by this. It duplicated the OMAP3 non-CORE DPLL clkops structure. The OMAP4 variant of this clkops structure has been removed, and since there was nothing else currently in clock44xx.c, it too has been removed -- it can always be added back later when there is some content for it. (The OMAP4 clock autogeneration scripts have been updated accordingly.)

* OMAP2/3 clock: Extend find_idlest() to pass back idle state valueRanjith Lohithakshan2010-02-24
| | | | | | | | | | | | | | | | Current implementation defines clock idle state indicators based on the cpu information (cpu_is_omap24xx() or cpu_is_omap34xx()) in a system wide manner. This patch extends the find_idlest() function in clkops to pass back the idle state indicator for that clock, thus allowing idle state indicators to be defined on a per clock basis if required. This is specifically needed on AM35xx devices as the new IPSS clocks indicates the idle status (0 is idle, 1 is ready) in a way just opposite to how its handled in OMAP3 (0 is ready, 1 is idle).

* OMAP2/3/4 clock: move clksel clock functions into mach-omap2/clkt_clksel.cPaul Walmsley2010-01-26
| | | | | | | | | | | | | | | | | | | | | | Move all clksel-related clock functions from mach-omap2/clock.c to mach-omap2/clkt_clksel.c. This is intended to make the clock code easier to understand, since all of the functions needed to manage clksel clocks are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for clksel clocks alon. This should reduce unnecessary console noise when debugging. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be moved to the plat-omap/ directory to be shared.

* OMAP2/3 clock: split, rename omap2_wait_clock_ready()Paul Walmsley2009-07-24
| | | | | | | | | | | | | | | | | | | | | | Some OMAP2/3 hardware modules have CM_IDLEST attributes that are not handled by the current omap2_wait_clock_ready() code. In preparation for patches that fix the unusual devices, rename the function omap2_wait_clock_ready() to omap2_wait_module_ready() and split it into three parts: 1. A clkops-specific companion clock return function (by default, omap2_clk_dflt_find_companion()) 2. A clkops-specific CM_IDLEST register address and bit shift return function (by default, omap2_clk_dflt_find_idlest()) 3. Code to wait for the CM to indicate that the module is ready (omap2_cm_wait_idlest()) Clocks can now specify their own custom find_companion() and find_idlest() functions; used in subsequent patches.

* [ARM] omap: add support for bypassing DPLLsRussell King2009-02-19
| | | | | | | | | | | | | | | | | | | | This roughly corresponds with OMAP commits: 7d06c48, 3241b19, 88b5d9b, 18a5500, 9c909ac, 5c6497b, 8b1f0bd, 2ac1da8. For both OMAP2 and OMAP3, we note the reference and bypass clocks in the DPLL data structure. Whenever we modify the DPLL rate, we first ensure that both the reference and bypass clocks are enabled. Then, we decide whether to use the reference and DPLL, or the bypass clock if the desired rate is identical to the bypass rate, and program the DPLL appropriately. Finally, we update the clock's parent, and then disable the unused clocks. This keeps the parents correctly balanced, and more importantly ensures that the bypass clock is running whenever we reprogram the DPLL. This is especially important because the procedure for reprogramming the DPLL involves switching to the bypass clock. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] omap: arrange for clock recalc methods to return the rateRussell King2009-02-14
| | | | | | | | | | | | | linux-omap source commit 33d000c99ee393fe2042f93e8422f94976d276ce introduces a way to "dry run" clock changes before they're committed. However, this involves putting logic to handle this into each and every recalc function, and unfortunately due to the caching, led to some bugs. Solve both of issues by making the recalc methods always return the clock rate for the clock, which the caller decides what to do with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

This mostly involves: - converting some asm/ includes to linux/ includes - cleaning up some whitespace - getting rid of braces for conditionals with single following statements Also take care of a few odds and ends, including: - getting rid of unlikely() and likely() - none of this code is particularly fast-path code, so the performance impact seems slim; and some of those likely() and unlikely() indicators are probably not as accurate as the ARM's branch predictor - removing some superfluous casts linux-omap source commit is 347df59f5d20fdf905afbc26b1328b0e28a8a01b.

* ARM: OMAP2: Clock: New OMAP2/3 DPLL rate rounding algorithmPaul Walmsley2008-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new rate rounding algorithm for DPLL clocks on the OMAP2/3 architecture. For a desired DPLL target rate, there may be several multiplier/divider (M, N) values which will generate a sufficiently close rate. Lower N values result in greater power economy. However, lower N values can cause the difference between the rounded rate and the target rate ("rate error") to be larger than it would be with a higher N. This can cause downstream devices to run more slowly than they otherwise would. This DPLL rate rounding algorithm: - attempts to find the lowest possible N (DPLL divider) to reach the target_rate (since, according to Richard Woodruff <r-woodruff@ti.com>, lower N values save more power than higher N values). - allows developers to set an upper bound on the error between the rounded rate and the desired target rate ("rate tolerance"), so an appropriate balance between rate fidelity and power savings can be set. This maximum rate error tolerance is set via omap2_set_dpll_rate_tolerance(). - never returns a rounded rate higher than the target rate. The rate rounding algorithm caches the last rounded M, N, and rate computation to avoid rounding the rate twice for each clk_set_rate() call. (This patch does not yet implement set_rate for DPLLs; that follows in a future patch.) The algorithm trades execution speed for rate accuracy. It will find the (M, N) set that results in the least rate error, within a specified rate tolerance. It does this by evaluating each divider setting - on OMAP3, this involves 128 steps. Another approach to DPLL rate rounding would be to bail out as soon as a valid rate is found within the rate tolerance, which would trade rate accuracy for execution speed. Alternate implementations welcome. This code is not yet used by the OMAP24XX DPLL clock, since it is currently defined as a composite clock, fusing the DPLL M,N and the M2 output divider. This patch also renames the existing OMAP24xx DPLL programming functions to highlight that they program both the DPLL and the DPLL's output multiplier.
