Tony Lindgren 05b5ca9b10 omap1: Fix booting for 15xx and 730 with omap1_defconfig
For omap15xx and 730 we need to use the MPU timer
as the 32K timer is not available. For omap16xx
we want to use the 32K timer because of PM. Fix this
by allowing to build in both timers.

Ben Gamari dc69d1af9e omap2: Make OMAP2PLUS select OMAP_DM_TIMER
It appears that arch/arm/mach-omap2/timer-gp.o is needed by OMAP2PLUS.
Since timer-gp.o has direct dependencies on omap_dm_timer_*, it seems
correct for the architecture to depend upon OMAP_DM_TIMER, otherwise
unsuspecting integrators will be faced with a whole bunch of linker
errors at the end of their kernel build:

Thara Gopinath b35cecf978 OMAP4: Smartreflex framework extensions
This patch extends the smartreflex framework to support
OMAP4. 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.

Thara Gopinath fa765823a3 OMAP3: PM: Adding smartreflex class3 driver
Smartreflex Class3 implementation continuously monitors
silicon performance  and instructs the Voltage Processors
to increase or decrease the voltage.
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.

Thara Gopinath 984aa6dbf4 OMAP3: PM: Adding smartreflex driver support.
SmartReflex modules do adaptive voltage control for real-time
voltage adjustments. With Smartreflex the power supply voltage
can be adapted to the silicon performance(manufacturing process,
temperature induced performance, age induced performance etc).

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.
Major contributors to this driver are
Lesly A M, Rajendra Nayak, Kalle Jokiniemi, Paul Walmsley,
Nishant Menon, Kevin Hilman.

Tero Kristo 79dcfdd407 OMAP3: PM: Added support for L2 aux ctrl register save and restore
This patch adds a save and restore mechanism for ARM L2 auxiliary control
register. The feature is enabled by default for GP devices, but for HS/EMU
devices the user must enable the service and define the PPA service ID to
be used for setting L2 aux ctrl, as this is not currently supported by the
bootloader. If nobody alters the contents of L2 aux ctrl from its reset
value, this feature is not needed.

Kconfig option to enable HS/EMU L2 aux save and restore:
- OMAP3_L2_AUX_SECURE_SAVE_RESTORE
Kconfig option to select HS/EMU PPA service for setting L2 aux ctrl:
- OMAP3_L2_AUX_SECURE_SERVICE_SET_ID

- Also merge in 34xx GPMC changes to add fields wr_access and
  wr_data_mux_bus from Adrian Hunter

- Remove memory initialization call omap2_init_memory() until
  until more generic memory initialization patches are posted.
  It's OK to rely on bootloader initialization until then.

Paul Walmsley d459bfe01f ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain code
This patch creates an interface to the clockdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

The patch also adds clockdomain usecount tracking.  This is intended
to be called whenever the first clock in a clockdomain is enabled, or
when the last enabled clock in a clockdomain is disabled.  If the
clockdomain is in software-supervised mode, the code will force-wakeup
or force-sleep the clockdomain.  If the clockdomain is in
hardware-supervised mode, the first clock enable will add sleep and
wakeup dependencies on a user-selectable set of parent domains (usually
MPU & IVA2), and the disable will remove them.

Each clockdomain will be defined in later patches as static
structures.  The clockdomain structures are linked into a list at boot
by clkdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().

Paul Walmsley ad67ef6848 ARM: OMAP2: Powerdomain: Add base OMAP2/3 powerdomain code
This patch creates an interface to the powerdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

Each powerdomain will be defined in later patches as static
structures.  Also defined are dependencies between powerdomains,
used for adding and removing PM_WKDEP and CM_SLEEPDEP bits.  The
powerdomain structures are linked into a list at boot by
pwrdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_POWERDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().

Kevin Hilman 06cad098d2 ARM: OMAP: Fix clockevent support for hrtimers
One-shot mode was broken in MPU-timer support for OMAP1 due to a typo.

Also, ensure timer is stopped before changing the auto-reload flag.
The TRM says changing the AR flag when timer is running is undefined.

Also set GENERIC_CLOCKEVENTS for all omaps.

David Brownell f604931238 ARM: OMAP: abstract debug card setup (smc, leds)
Additional cleanup for debug boards on H2/P2/H3/H4:  move the init
code that's not board-specific into a new file where it can be easily
shared between all the different boards (avoiding code duplication,
and making it easier to support more devices).  Make H4 use that.

This should be easy to drop in to the OMAP1 boards using these debug
cards; the only difference seems to be that the p2 does an extra reset
of the smc using the fpga (probably all boards could do that, if it's
necessary) and doesn't use the gpio mux or request APIs.
