2010-05-20OMAP2+ clock: remove DEFAULT_RATE clksel_rate flagPaul Walmsley1-23/+23
The DEFAULT_RATE clksel_rate flag is essentially useless. It was set on some of the lowest divisors, which, when switching to a much higher-rate parent, could have potentially resulted in rates that exceeded the hardware specifications for downstream clocks in the window between the clk_set_parent(), and a subsequent clk_set_rate(). It seems much safer to just remove the flag and always use the highest available divisor (resulting in the lowest possible rate) after the switch, and this patch does so. Ideally, it would be best to first attempt to switch to a divisor that matches the clock's rate with the previous parent, if at all possible. But that is a project for some other day or some other person. The parent changing code is rarely used. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2010-05-20OMAP2 PRCM: convert OMAP2 PRCM macros to the _SHIFT/_MASK suffixesPaul Walmsley1-2/+2
Fix all of the remaining OMAP2 PRCM register shift/bitmask macros that did not use the _SHIFT/_MASK suffixes to use them. This makes the use of these macros consistent. It is intended to reduce error, as code can be inspected visually by reviewers to ensure that bitshifts and bitmasks are used in the appropriate places.

2010-02-24OMAP clock: drop RATE_FIXED clock flagPaul Walmsley1-5/+2
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>
2010-02-24OMAP2 clock: drop DELAYED_APP clock flagPaul Walmsley1-20/+0
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.

2010-02-24OMAP2 clock: split OMAP2420, OMAP2430 clock data into their own filesPaul Walmsley1-0/+1933
In preparation for multi-OMAP2 kernels, split mach-omap2/clock2xxx_data.c into mach-omap2/clock2420_data.c and mach-omap2/clock2430_data.c. 2430 uses a different device space physical memory layout than past or future OMAPs, and we use a different virtual memory layout as well, which causes trouble for architecture-level code/data that tries to support both. 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.
