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.

This patch adds support for DPLL autoidle control to the OMAP3 clock
framework. These functions will be used by the noncore DPLL enable
and disable code - this is because, according to the CDP code, the
DPLL autoidle status must be saved and restored across DPLL
lock/bypass/off transitions.
N.B.: the CORE DPLL (DPLL3) has three autoidle mode options, rather
than just two. This code currently does not support the third option,
low-power bypass autoidle.

Add a new OMAP chip identification interface, omap_chip_id.
omap_chip_id is a structure which contains one bit for each OMAP2/3
CPU type, and on 3430, ES level. For example, the CHIP_IS_OMAP2420
bit is set in omap_chip at boot on an OMAP2420. On OMAP3430ES2, both
CHIP_IS_OMAP3430 and CHIP_IS_OMAP3430ES2 bits are set.
omap_chip is set in mach-omap2/id.c by _set_omap_chip(). Other
code should use the omap_chip_is() function to test against omap_chip.
Also, clean up id.c by splitting some code out of
omap_check_revision() into its own function, _set_system_rev(); and
converting some debug printk()s into pr_debug().
Second revision.

debugfs can provide the infrastructure to trace the dependencies of
clock tree hierarchy quite visibly. This patch enables to keep track
of clock tree hierarchy and expose their attributes under each clock
directry as below:
omap:~# tree -d -L 2 /debug/clock/omap_32k_fck/
/debug/clock/omap_32k_fck/
|-- gpt10_fck
|-- gpt11_fck
|-- gpt1_fck
|-- per_32k_alwon_fck

| `-- wdt3_fck
|-- ts_fck
`-- wkup_32k_fck
|-- gpio1_fck
`-- wdt2_fck
14 directories
omap:~# tree /debug/clock/omap_32k_fck/gpt10_fck/
/debug/clock/omap_32k_fck/gpt10_fck/
|-- flags
|-- rate
`-- usecount
0 directories, 3 files
Although, compared with David Brownell's small patch, this may look
bit overkilling, I expect that this debugfs can deal with other PRCM
complexities at the same time. For example, powerdomain dependencies
can be expressed by using symbolic links of these clocks if
powerdomain supports dubgfs as well.

This patch adds the use of write posting for the timer. Previously, every
write could lock the requestor for almost 3x32KHz cycles. This patch only
synchronizes before writes and reads instead of after them and it does
it on per register basis. Doing it this way there is some chance to hide
some of the sync latency. It also removes some needless reads when
non-posted mode is there. With out this fix the read/writes take almost
2% CPU load @500MHz just waiting on tick timer registers.
Also define new 34xx only registers.

Fedora reports that mem_init()'s zap_low_mappings(), extended to SMP in
61165d7a035f6571c7576e7f51e7230157724c8d x86: fix app crashes after SMP
resume causes 32-bit Intel Mac machines to reboot very early when
booting with EFI.
The EFI code appears to manage low mappings for itself when needed; but
like many before it, confuses PSE with PAE. So it has only been mapping
half the space it needed when PSE but not PAE. This remained unnoticed
until we moved the SMP zap_low_mappings() before
efi_enter_virtual_mode(). Presumably could have been noticed years ago
if anyone ran a UP kernel on such machines?
