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.

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.

2012-07-05ARM: 7443/1: Revert "new way of handling ERESTART_RESTARTBLOCK"Will Deacon
This reverts commit 6b5c8045ecc7e726cdaa2a9d9c8e5008050e1252. Conflicts: arch/arm/kernel/ptrace.c The new syscall restarting code can lead to problems if we take an interrupt in userspace just before restarting the svc instruction. If a signal is delivered when returning from the interrupt, the TIF_SYSCALL_RESTARTSYS will remain set and cause any syscalls executed from the signal handler to be treated as a restart of the previously interrupted system call. This includes the final sigreturn call, meaning that we may fail to exit from the signal context. Furthermore, if a system call made from the signal handler requires a restart via the restart_block, it is possible to clear the thread flag and fail to restart the originally interrupted system call. The right solution to this problem is to perform the restarting in the kernel, avoiding the possibility of handling a further signal before the restart is complete. Since we're almost at -rc6, let's revert the new method for now and aim for in-kernel restarting at a later date.

aess IP blocks The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special programming for them to enter idle. Without this programming, they will prevent the rest of the chip from entering full chip idle. To implement the idle programming cleanly, this will take some coordination between maintainers. This is likely to take some time, so it is probably best to leave this for 3.6 or 3.7. So, in the meantime, prevent these IP blocks from being registered. Later, once the appropriate support is available, this patch can be reverted. This second version comments out the IP block data since Benoît didn't like removing it.

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.

2012-07-04ARM: OMAP2+: hwmod: add omap_hwmod_get_main_clk() APITarun Kanti DebBarma
Add an API to get main clock name associated with a given @oh. This will avoid the need to construct fclk names during early initialization in order to get fclk handle using clk_get().

2012-07-04ARM: OMAP3+: dpll: optimize noncore dpll locking logicVikram Pandita
If the dpll is already locked, code can be optimized to return much earlier than doing redundent set of lock mode and wait on idlest.

2012-07-04ARM: OMAP3: control: add definition for CONTROL_CAMERA_PHY_CTRLSakari Ailus
The register is used to configure the behaviour of the CSI-2 and CCP-2 receivers. This register is available only in OMAP3630. The original patch was submitted by Vimarsh Zutshi.

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]).
