2012-07-05ARM: OMAP2+: Remove unnecessary ifdef around __omap2_set_globalsVaibhav Hiremath
The function __omap2_set_globals() can be common across all platforms/architectures, even in case of omap4, internally it calls same set of functions as in __omap2_set_globals() function (except for sdrc). This patch adds new config flag SOC_HAS_OMAP2_SDRC to handle sdrc, so that we can reuse same function across omap2/3/4...

2012-07-05ARM: OMAP2+: am33xx: Change cpu_is_am33xx to soc_is_am33xxVaibhav Hiremath
As per recent discussion on the linux-omap list, we are moving in the direction where, we will have only architecture, ARCH_OMAP2PLUS and all devices/platforms will be treated as a SoC underneath. So the first step in this direction is to adopt this change for all new devices getting in, converting cpu_is_am33xx/335x() ==> soc_is_am33xx/335x() Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2012-07-05ARM: OMAP2+: am33xx: Make am33xx as a separate classVaibhav Hiremath
Initially, we decided to make am33xx family of device to fall under omap3 class (cpu_is_omap34xx() = true), since it carries Cortex-A8 core. But while adding complete baseport support (like, clock, power and hwmod) support, it is observed that, we are creating more and more problems by treating am33xx device as omap3 family, as nothing matches between them (except cortex-A8 mpu). So, after long discussion we have came to the conclusion that, we should not consider am33xx device as omap3 family, instead create separate class (SOC_AM33XX) under OMAP2PLUS. This means, for am33xx device, cpu_is_omap34xx() will return false, and only cpu_is_am33xx() will be true.

2012-07-04ARM: OMAP2+: hwmod code: add support to set dmadisable in hwmod frameworkKishon Vijay Abraham I
The DMADISABLE bit is a semi-automatic bit present in sysconfig register of some modules. When the DMA must perform read/write accesses, the DMADISABLE bit is cleared by the hardware. But when the DMA must stop for power management, software must set the DMADISABLE bit back to 1. In cases where the ROMCODE/BOOTLOADER uses dma, the hardware clears the DMADISABLE bit (but the romcode/bootloader might not set it back to 1). In order for the kernel to start in a clean state, it is necessary for the kernel to set DMADISABLE bit back to 1 (irrespective of whether it's been set to 1 in romcode or bootloader). During _reset of the (hwmod)device, the DMADISABLE bit is set so that it does not prevent idling of the system. (NOTE: having DMADISABLE to 0, prevents the system to idle) DMADISABLE bit is present in usbotgss module of omap5.

and make them __weak Some prm and cm registers read/write and status functions are built only for some custom OMAP2+ builds and are stubbed in header files for other builds under ifdef statements. But this results in adding new CONFIG_ARCH_OMAPXXX checks when SOCs are added in the future. So move them to a common place for OMAP2+ and make them 'weak' implementations.

2012-07-04ARM: OMAP2+: powerdomain code: Fix Wake-up power domain power statusJon Hunter
The wake-up power domain is an alway-on power domain and so this power domain does not have a power state status (PM_PWSTST_xxx) register that indicates the current state. However, during the registering of the wake-up power domain the state of the domain is queried by calling pwrdm_read_pwrst(). This actually tries to read a register that does not exist and returns a value of 0 that indicates that the current state is OFF. The OFF state count of the wake-up power domain is then set to 1 and the current state to OFF. Both of which are incorrect. To fix this, if a power domain only supports the ON state, do not attempt to read the power state status register and simply return ON as the current power state. This is based upon Tony's current linux-omap master branch. Testing: - Boot tested on OMAP4460 panda. - Boot tested on OMAP3430 beagle and validated CORE RET still working (using Paul's 32k timer patch [1]).

2012-07-04ARM: OMAP4: clockdomain/CM code: Update supported transition modesJon Hunter
For OMAP3+ devices, the clock domains (CLKDMs) support one or more of the following transition modes ... NO_SLEEP (0x0) - A clock domain sleep transition is never initiated, irrespective of the hardware conditions. SW_SLEEP (0x1) - A software-forced sleep transition. The transition is initiated when the associated hardware conditions are satisfied SW_WKUP (0x2) - A software-forced clock domain wake-up transition is initiated, irrespective of the hardware conditions. HW_AUTO (0x3) - Hardware-controlled automatic sleep and wake-up transition is initiated by the PRCM module when the associated hardware conditions are satisfied. For OMAP4 devices, SW_SLEEP is equivalent to HW_AUTO and NO_SLEEP is equivalent to SW_WKUP. The only difference between HW_AUTO and SW_SLEEP for OMAP4 devices is that the PRM_IRQSTATUS_MPU.TRANSITION_ST interrupt status is set in case of SW_SLEEP transition, and not set in case of HW_AUTO transition. For OMAP4 devices, all CLKDMs support HW_AUTO and therefore we can place the CLKDMs in the HW_AUTO state instead of the SW_SLEEP mode. Hence, we do not need to use the SW_SLEEP mode. With regard to NO_SLEEP and SW_WKUP it is preferred to use SW_WKUP mode if the CLKDM supports it and so use this mode instead of NO_SLEEP where possible. For a software perspective the above 4 modes are represented by the following flags to indicate what modes are supported by each of the CLKDMs. CLKDM_CAN_DISABLE_AUTO --> NO_SLEEP CLKDM_CAN_ENABLE_AUTO --> HW_AUTO CLKDM_CAN_FORCE_SLEEP --> SW_SLEEP CLKDM_CAN_FORCE_WAKEUP --> SW_WKUP By eliminating the SW_SLEEP mode the the mapping of the flags for OMAP4 devices can becomes ...

2012-06-20ARM: OMAP: Fix Beagleboard DVI reset gpioRuss Dill
Commit e813a55eb9c9bc6c8039fb16332cf43402125b30 ("OMAP: board-files: remove custom PD GPIO handling for DVI output") moved TFP410 chip's powerdown-gpio handling from the board files to the tfp410 driver. One gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in the Beagle board file. This causes the tfp410 driver to fail to request the gpio on Beagle, causing the driver to fail and thus the DVI output doesn't work. This patch removes several boot errors from board-omap3beagle.c: - gpio_request: gpio--22 (DVI reset) status -22 - Unable to get DVI reset GPIO There is a combination of leftover code and revision confusion. Additionally, xM support is currently a hack. For original Beagleboard this removes the double initialization of GPIO 170, properly configures it as an output, and wraps the initialization in an if block so that xM does not attempt to request it. For Beagleboard xM it removes reference to GPIO 129 which was part of rev A1 and A2 designs, but never functioned. It then properly assigns beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the hack of initializing it high. Additionally, it uses gpio_set_value_cansleep since this GPIO is connected through i2c. Unfortunately, there is no way to tell the difference between xM A2 and A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL GPIO used on A3 and beyond is not used on rev A1 and A2, there are no problems created by this fix.

2012-06-18ARM: OMAP2+: control: new APIs to configure boot address and modeOmar Ramirez Luna
SCM contains boot addr and boot mode registers to control other processors on different OMAP versions. It controls the boot address and mode for DSP based subsystems like: IVA 2.1 (OMAP2430), IVA 2.2 (OMAP3) and DSP (OMAP4). If contained within SCM registers, when a processor is booting it uses BOOTADDR to start running the code at that location. BOOTMOD register specifies a different set of modes for the processor to execute when booting (from direct, idle, self-loop, user and default). Since there was no offset associated with OMAP4, this patch defines it. Signed-off-by: Omar Ramirez Luna <omar.luna@linaro.org> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2012-06-18ARM: OMAP2+: hwmod: use init-time function pointer for _init_clkdmKevin Hilman

Rather than using cpu_is* checking at runtime, initialize an SoC specific function pointer for wait_target_ready(). While here, downgrade the BUG() to a WARN_ON() so it gives a noisy warning instead of causing a kernel panic. Signed-off-by: Kevin Hilman <khilman@ti.com> [paul@pwsan.com: convert to use soc_ops function pointers; add kerneldoc; move soc_ops functions to their own section in the code; integrated the _wait_target_ready() function with the OMAP2/OMAP4 variants; renamed the wait_module_ready field to wait_target_ready] Signed-off-by: Paul Walmsley <paul@pwsan.com>
2012-06-18ARM: OMAP4: hwmod: drop extra cpu_is check from _wait_target_disable()Kevin Hilman
_omap4_wait_target_disable() is called only from inside _omap4_disable_module() which is already protected by SoC specific checks. Remove the cpu_is check here. Signed-off-by: Kevin Hilman <khilman@ti.com>
2012-06-18ARM: OMAP2+: hwmod: use init-time function ptrs for enable/disable moduleKevin Hilman
The enable/disable module functions are specific to SoCs with OMAP4-class PRCM. Rather than use cpu_is* checks at runtime inside the enable/disable module functions, use cpu_is at init time to initialize function pointers only for SoCs that need them. NOTE: the cpu_is* check for _enable_module was different than the one for _disable_module, and this patch uses cpu_is_omap44xx() for both.

2012-06-18ARM: OMAP AM33xx: powerdomains: add AM335x supportVaibhav Hiremath
Add offset & mask fields to struct powerdomain In case of AM33xx family of devices, there is no consistency between PWRSTCTRL & PWRSTST register offsers in PRM space, for example - PRM_XXX PWRSTCTRL PWRSTST ======================================= PRM_PER_MOD: 0x0C, 0x08 PRM_WKUP_MOD: 0x04, 0x08 PRM_MPU_MOD: 0x00, 0x04 PRM_DEVICE_MOD: NA, NA And also, there is no consistency between bit-offsets inside PWRSTCTRL & PWRSTST register, for example - PRM_XXX LOGICRET MEMON MEMRET ======================================= GFX_PWRCTRL: 2, 17, 6 PER_PWRCTRL: 3, 25, 29 MPU_PWRCTRL: 2, 18, 22 WKUP_PWRCTRL: 3, NA, NA This means, we need to maintain and pass on all this information in powerdomain handle; so adding fields for, - PWRSTCTRL/ST register offset - Logic retention state mask - mem_on/ret/pwrst/retst mask Currently, this fields is only applicable and used for AM33XX devices.
