ARM: config: sort select statements alphanumerically As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines. We have four testers reporting success of this change (Tony, Stephen, Linus and Sekhar.)

Say Y if you want to reset unused clocks during boot.
This option saves power, but assumes all drivers are

If you are booting from another operating system, you
probably do not want this option enabled until your
device drivers work properly.

ARM: OMAP2+: Disable code that currently does not work with multiplaform We still need to fix up few places for multiplatform support, but that can proceed separately. Fix the issue by making the problem drivers depends !ARCH_MULTIPLATFORM for now. The remaining pieces that are not multiplatform compatible for omap2+ SoCs are: 1. Some drivers are using custom omap_dm_timer calls There are two drivers that are directly usign omap hardware timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and drivers/staging/tidspbridge/core/dsp-clock.c. These can be fixed for multiplatform by allowing a minimal set of hardware timers to be accessed, and for some functionality by using the hrtimer framework. 2. Hardware OMAP4_ERRATA_I688 needs to be fixed up This can't be enabled for multiplatform configurations in it's current form. It may be possible to fix it up to do instruction replacement early on during init. Luckily it looks like this errata does not seem to get hit with mainline kernel code alone at least currently. 3. Legacy header needed for omap-sham.c Looks like it still needs mach/irqs.h for omap1 that does not exist for multiplatform systems. Just ifdef it for now. 4. Mailbox is waiting to get moved to drivers Disable it for now to avoid adding a dependency to the mailbox patches.

ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER CONFIG_OMAP_32K_TIMER is kind of standing on the single zImage way. Make OMAP2+ timer code independant from the CONFIG_OMAP_32K_TIMER setting. To remove the dependancy, several conversions/additions had to be done: 1) Timer initialization functions are named by the platform name and the clock source in use. This also makes it possible to define and use the GPTIMER as the clock source instead of the 32K timer on platforms that do not have the 32K timer ip block or the 32K timer is not wired on the board. Currently, the the timer is chosen in the machine_desc structure on per board basis. Later, DT should be used to choose the timer. 2) Settings under the CONFIG_OMAP_32K_TIMER option are used as defaults and those under !CONFIG_OMAP_32K_TIMER are removed. This removes the CONFIG_OMAP_32K_TIMER on OMAP2+ timer code. 3) Since we have all the timers defined inside machine_desc structure and we no longer need the fallback to gp_timer clock source in case 32k_timer clock source is unavailable (namely on AM33xx), we no longer need the #ifdef around omap2_sync32k_clocksource_init() function. Remove the #ifdef CONFIG_OMAP_32K_TIMER around the omap2_sync32k_clocksource_init() function.
