From e9b98f6040f5a7a04d659759d83ea28d9c528800 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 26 Jan 2010 20:12:57 -0700 Subject: OMAP clock: make the fixed divisor clock code available for all OMAPs One of the OMAP1 clocks can use the fixed divisor recalculation code introduced in the OMAP2 clock code, so rename the omap2_fixed_divisor_recalc() function to omap_fixed_divisor_recalc() and make it available to all OMAPs. A followup patch converts the OMAP1 clock.

This is intended to make the clock code easier to understand, since all of the functions needed to manage DPLLs 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 DPLLs alone. 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. Thanks to Alexander Shishkin for his comments to improve the patch description.

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. Thanks to Alexander Shishkin for his comments to improve the patch description.

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).

The rate-changing component can be more directly accomplished by dropping the .set_rate and .round_rate function pointers from those CONFIG_PARTICIPANT struct clks. As far as the parent-changing component is concerned, it turns out that none of the CONFIG_PARTICIPANT clocks have multiple parent choices, so all that is necessary is for omap2_clk_set_parent() to bail out early if the new parent is equal to the old parent. Implement this change and get rid of the flag, which has always had a confusing name (it appears to be a Kconfig option, falsely).

charset=UTF-8 Content-Transfer-Encoding: 8bit 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.)

8c34974ab0ecbbcdabd343f8cd0013cd2d2b0fa8 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Mon, 22 Feb 2010 22:09:24 -0700 Subject: OMAP2 clock: drop DELAYED_APP clock flag 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.

This makes the code easier to read. Add some additional debugging pr_debug()s here also to help others understand what is going on. Revise the omap2_clk_disable() logic so that it now attempts to disable the clock's clockdomain before recursing up the clock tree. Simultaneously, ensure that omap2_clk_enable() is called on parent clocks first, before enabling the clockdomain. This ensures that a parent clock's clockdomain is enabled before the child clock's clockdomain. These sequences should be the inverse of each other. Revise the omap2_clk_enable() logic so that it now cleans up after itself upon encountering an error. Previously, an error enabling a parent clock could have resulted in inconsistent usecounts on the enclosing clockdomain. Remove the trivial _omap2_clk_disable() and _omap2_clk_enable() static functions, and replace it with the clkops calls that they were executing. For all this to work, the clockdomain omap2_clkdm_clk_enable() and omap2_clkdm_clk_disable() code must not return an error on clockdomains without CLKSTCTRL registers; so modify those functions to simply return 0 in that case. While here, add some basic kerneldoc documentation on both functions, and get rid of some old non-CodingStyle-compliant comments that have existed since the dawn of time (at least, the OMAP clock framework's time).
