* mailbox/omap: move the OMAP mailbox framework to driversSuman Anna2013-06-111-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mailbox hardware (in OMAP) uses a queued mailbox interrupt mechanism that provides a communication channel between processors through a set of registers and their associated interrupt signals by sending and receiving messages. The OMAP mailbox framework/driver code is moved to be under drivers/mailbox, in preparation for adapting to a common mailbox driver framework. This allows the build for OMAP mailbox to be enabled (it was disabled during the multi-platform support). As part of the migration from plat and mach code: - Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers. - mailbox.h under plat-omap/plat/include has been split into a public and private header files. The public header has only the API related functions and types. - The module name mailbox.ko from plat-omap is changed to omap-mailbox.ko - The module name mailbox_mach.ko from mach-omapX is changed as mailbox_omap1.ko for OMAP1 mailbox_omap2.ko for OMAP2+ Cc: Tony Lindgren <tony@atomide.com> [gregkh@linuxfoundation.org: ack for staging part] Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Omar Ramirez Luna <omar.ramirez@copitl.com> Signed-off-by: Suman Anna <s-anna@ti.com>

| * ARM: OMAP2+: Get rid of custom OMAP_32K_TIMER_HZSantosh Shilimkar2013-02-011-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The timekeeping doesn't depend on HZ value in presence of fine grained clocksource and hence there should not be any time drift because of HZ value which was chosen to be divisor of 32768. OMAP has been using HZ = 128 value to avoid any time drift issues because of 32768 HZ clock. But with various measurements performed with HZ = 100, no time drift is observed and it also proves the point about HZ not having impact on time keeping on OMAP. Very informative thread on this topic is here: https://lkml.org/lkml/2013/1/29/435 Special thanks to John Stulz, Arnd Bergmann and Russell King for their valuable suggestions.

* | ARM: OMAP2+: Disable code that currently does not work with multiplaformTony Lindgren2013-01-111-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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_TIMERIgor Grinberg2012-11-211-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* ARM: fix __io macro for PCMCIARob Herring2012-04-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

The changes are minor like compiling smartreflex Kconfig option for OMAP4 also, and a couple of OMAP4 checks in the smartreflex framework. The change in sr_device.c where new logic has to be introduced for reading the efuse registers is due to the fact that in OMAP4 the efuse registers are 24 bit aligned. A __raw_readl will fail for non-32 bit aligned address and hence the 8-bit read and shift. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

This patch adds smartreflex class 3 driver. This driver hooks up with the generic smartreflex driver smartreflex.c to abstract out class specific implementations out of the generic driver. Class3 driver is chosen as the default class driver for smartreflex. If any other class driver needs to be implemented, the init of that driver should be called from the board file. That way the new class driver will over-ride the Class3 driver. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

There are differnet classes of smartreflex implementation. Class-0: Manufacturing Test Calibration Class-1: Boot-Time Software Calibration Class-2: Continuous Software Calibration Class-3: Continuous Hardware Calibration Class-4: Fully Integrated Power Management OMAP3 has two smartreflex modules one associated with VDD MPU and the other associated with VDD CORE. This patch adds support for smartreflex driver. The driver is designed for Class-1 , Class-2 and Class-3 support and is a platform driver. Smartreflex driver can be enabled through a Kconfig option "SmartReflex support" under "System type"->"TI OMAP implementations" menu. Smartreflex autocompensation feature can be enabled runtime through a debug fs option. To enable smartreflex autocompensation feature echo 1 > /debug/voltage/vdd_<X>/smartreflex/autocomp To disable smartreflex autocompensation feature echo 0 > /debug/voltage/vdd_<X>/smartreflex/autocomp where X can be mpu, core , iva etc. This patch contains code originally in linux omap pm branch.
