* OMAP4: clock: Add dummy clock nodes for interface clocksSantosh Shilimkar2010-02-241-6/+0
| | | | | | | | | | | | | | | | 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. To avoid poulluting the drivers dummy clock nodes are created (The autogeneration script has been updated accordingly).

* OMAP clock: drop RATE_FIXED clock flagPaul Walmsley2010-02-241-16/+9
| | | | | | | | | | | | | | | | | | 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>
* OMAP clock: drop .id field; ensure each clock has a unique namePaul Walmsley2010-02-241-7/+3
| | | | | | | | After the clkdev conversion, the struct clk.id field became superfluous, so, drop it. Bring the clock names closer to the TRMs and ensure they are unique for debugfs. Signed-off-by: Paul Walmsley <paul@pwsan.com>
* OMAP1 clock: convert armwdt_ck to use the fixed divisor recalc functionPaul Walmsley2010-01-261-1/+2
| | | | | | | The armwdt_ck clock uses a fixed divisor, so it can use the OMAP clock fixed divisor recalculation code, rather than a custom function. Signed-off-by: Paul Walmsley <paul@pwsan.com>

| * OMAP1 clock: remove __initdata from struct clk_functions to prevent crashCory Maccarrone2010-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Commit 52650505fbf3a6ab851c801f54e73e76c55ab8da added an __initdata decoration to the structure containing the clk_enable and clk_disable functions. Once init data was freed, these pointers went to null, and the next enable or disable call caused the kernel to crash. This change removes this decoration.

| * OMAP1 clock: Add missing clocks for OMAP 7xxCory Maccarrone2010-01-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds in some missing clocks that were needed as a result of 526505... (OMAP1 clock: convert mach-omap1/clock.h to mach-omap1/clock_data.c). Prior to this, it was just assumed that these clocks existed for all devices, and it was used directly instead of calling it out with a clock_get call or similar. So, not having the CK_7XX meant these clocks weren't being used anymore for omap 7xx devices, which broke things badly.

* OMAP1 clock: convert mach-omap1/clock.h to mach-omap1/clock_data.cPaul Walmsley2009-12-111-0/+843
The OMAP1 clock code currently #includes a large .h file full of static data structures. Instead, define the data in a .c file. Russell King <linux@arm.linux.org.uk> proposed this new arrangement: http://marc.info/?l=linux-omap&m=125967425908895&w=2 This patch also deals with most of the flagrant checkpatch violations. While here, separate the mpu_rate data structures out into their own files, opp.h and opp_data.c. In the long run, these mpu_rate tables should be replaced with OPP code. Also includes a patch from Felipe Balbi <felipe.balbi@nokia.com> to mark omap1_clk_functions as __initdata to avoid a section warning: http://patchwork.kernel.org/patch/64366/ Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Felipe Balbi <felipe.balbi@nokia.com> Cc: Nishanth Menon <nm@ti.com>
