| | | | | | | | | | | | | | | | | | | | | | | | The system to allow panel drivers to exists as attached to ctrl drivers did never work very well. It is not useed, and this patch removes it to make the driver cleaner. For now, controller drivers need to include also the panel driver code.

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).

While here, fix some comments. The hwmod_class structures in this patch were designed and proposed by Benoît Cousson <b-cousson@ti.com> and were refined in a discussion between Thara Gopinath <thara@ti.com>, Kevin Hilman <khilman@deeprootsystems.com>, and myself.

This is a coding style issue, similar to commit 82e9bd588563c4e22ebb55b684ebec7e310cc715. Move the existing hwmod data from .h files to .c files. While here, convert "omap34xx" to "omap3xxx" in the hwmod files, since most of these structures should be reusable across all OMAP3 chips.

| | * | | OMAP hwmod: convert hwmod to use hardware clock names rather than clkdev dev+conPaul Walmsley2010-02-245-34/+23

Currently the hwmod code uses clkdev device + connection addressing to identify clocks. This causes problems in the hwmod autogeneration process, since the TI hardware database doesn't use platform_device or clkdev addressing; it uses a single clock signal name string, which tends to bear some resemblance to what is used in the OMAP TRMs. This patch converts the hwmod code and existing data to use omap_clk_get_by_name(), introduced in the previous patch.

| | * | | OMAP clock: add omap_clk_get_by_name() for use by OMAP hwmod core codePaul Walmsley2010-02-242-0/+28

This causes problems in the hwmod autogeneration process, since the TI hardware database doesn't use platform_device or clkdev addressing; it uses a single clock signal name string, which tends to bear some resemblance to what is used in the OMAP TRMs. This patch adds a non-exported function to the OMAP clock code, omap_clk_get_by_name(). A subsequent patch will convert the hwmod code to use this function. This function is for use only by core code, and practically, no other code outside the hwmod code should need it. Device driver code in the kernel must not use this function, which is why it is not exported. Drivers should use the appropriate clock alias provided by the clkdev data structures, so driver code can be completely SoC-independent.

| | * | | OMAP clock: drop RATE_FIXED clock flagPaul Walmsley2010-02-247-52/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RATE_FIXED clock flag is pointless. In the OMAP1 clock code, it simply causes the omap1_clk_round_rate() function to return the current rate of the clock. omap1_clk_round_rate(), however, should never be called for a fixed-rate clock, since none of these clocks have a .round_rate function pointer set in their struct clk records. Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes the clock code to emit a warning if the OMAP clock maintainer was foolish enough to add a .round_rate function pointer to a fixed-rate clock. "Doctor, it hurts when I pretend that a fixed-rate clock is rate-changeable." "Then don't pretend that a fixed-rate clock is rate-changeable." It has no functional value. This patch drops the RATE_FIXED clock flag, removing it from all clocks that are so marked. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Richard Woodruff <r-woodruff2@ti.com>

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.

| | * | | OMAP2 clock: split OMAP2420, OMAP2430 clock data into their own filesPaul Walmsley2010-02-248-425/+2153

We tried using offsets from the virtual base last year, but those patches never made it upstream; so after some discussion with Tony about the best all-around approach, we'll just grit our teeth and duplicate the structures. The maintenance advantages of a single kernel config that can compile and boot on OMAP2, 3, and 4 platforms are simply too compelling. This approach does have some nice benefits beyond multi-OMAP 2 kernel support. The runtime size of OMAP2420-specific and OMAP2430-specific kernels is smaller, since unused clocks for the other OMAP2 chip will no longer be compiled in. (At some point we will mark the clock data __initdata and allocate it during registration, which will eliminate the runtime memory advantage.) It also makes the clock trees slightly easier to read, since 2420-specific and 2430-specific clocks are no longer mixed together. This patch also splits 2430-specific clock code into its own file, mach-omap2/clock2430.c, which is only compiled in for 2430 builds - mostly for organizational clarity. While here, fix a bug in the OMAP2430 clock tree: "emul_ck" was incorrectly marked as being 2420-only, when actually it is present on both OMAP2420 and OMAP2430. Thanks to Tony for some good discussions about how to approach this problem.

| | * | | OMAP3/4 clock: split into per-chip family filesPaul Walmsley2010-02-2417-332/+450

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.)

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).
