2011-07-09OMAP PM: remove OMAP_PM_NONE config optionJean Pihet
The current code base is not linking with the OMAP_PM_NONE option set. Since the option OMAP_PM_NOOP provides a no-op/debug layer, OMAP_PM_NONE can be removed. OMAP_PM_NOOP is enabled by default by Kconfig. Signed-off-by: Jean Pihet <j-pihet@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

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: arch/arm/mach-omap2/built-in.o: In function `omap2_gp_timer_set_mode': /home/bgamari/trees/linux-2.6/arch/arm/mach-omap2/timer-gp.c:84: undefined reference to `omap_dm_timer_stop' /home/bgamari/trees/linux-2.6/arch/arm/mach-omap2/timer-gp.c:88: undefined reference to `omap_dm_timer_get_fclk' /home/bgamari/trees/linux-2.6/arch/arm/mach-omap2/timer-gp.c:90: undefined reference to `omap_dm_timer_set_load_start' ...

2010-12-22OMAP4: Smartreflex framework extensionsThara Gopinath
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. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-12-22OMAP3: PM: Adding smartreflex class3 driverThara Gopinath
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. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-12-22OMAP3: PM: Adding smartreflex driver support.Thara Gopinath
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.

2008-08-19ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain codePaul Walmsley
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().
