| * ARM: OMAP: TI81XX: Prepare for addition of TI814X supportHemant Pedanekar2011-12-131-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates existing macros, functions used for TI816X, to enable addition of other SoCs belonging to TI81XX family (e.g., TI814X). The approach taken is to use TI81XX/ti81xx for code/data going to be common across all TI81XX devices. cpu_is_ti81xx() is introduced to handle code common across TI81XX devices. In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved in mach-omap2/common.c as same will be used for TI814X and is not board specific.

* | ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.Santosh Shilimkar2011-12-081-0/+9
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On OMAP4 SOC, intecronnects has many write buffers in the async bridges and they need to be drained before CPU enters into standby state. Patch 'OMAP4: PM: Add CPUX OFF mode support' added CPU PM support but OMAP errata i688 (Async Bridge Corruption) needs to be taken care to avoid issues like system freeze, CPU deadlocks, random crashes with register accesses, synchronisation loss on initiators operating on both interconnect port simultaneously. As per the errata, if a data is stalled inside asynchronous bridge because of back pressure, it may be accepted multiple times, creating pointer misalignment that will corrupt next transfers on that data path until next reset of the system (No recovery procedure once the issue is hit, the path remains consistently broken). Async bridge can be found on path between MPU to EMIF and MPU to L3 interconnect. This situation can happen only when the idle is initiated by a Master Request Disconnection (which is trigged by software when executing WFI on CPU). The work-around for this errata needs all the initiators connected through async bridge must ensure that data path is properly drained before issuing WFI. This condition will be met if one Strongly ordered access is performed to the target right before executing the WFI. In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained. IO barrier ensure that there is no synchronisation loss on initiators operating on both interconnect port simultaneously. Thanks to Russell for a tip to conver assembly function to C fuction there by reducing 40 odd lines of code from the patch.

Adding any function declarations into it and including it in multiple source file is expected to cause issues. Hence move all the static definitions from powerdomains.h file into powerdomains_data.c file. Also, create a new powerdomain section of the mach-omap2/Makefile, and rearrange the prcm-common part of the Makefile, now that the powerdomain code is in its own Makefile section.

* OMAP2+: wd_timer: disable on boot via hwmod postsetup mechanismPaul Walmsley2010-12-221-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OMAP watchdog timer IP blocks require a specific set of register writes to occur before they will be disabled[1], even if the device clocks appear to be disabled in the CM_*CLKEN registers. In the MPU watchdog case, failure to execute this reset sequence will eventually cause the watchdog to reset the OMAP unexpectedly. Previously, the code to disable this watchdog was manually called from mach-omap2/devices.c during device initialization. This causes the watchdog to be unconditionally disabled for a portion of kernel initialization. This should be controllable by the board-*.c files, since some system integrators will want full watchdog coverage of kernel initialization. Also, the watchdog disable code was not connected to the hwmod shutdown code. This means that calling omap_hwmod_shutdown() will not, in fact, disable the watchdog, and the goal of omap_hwmod_shutdown() is to be able to shutdown any on-chip OMAP device. To resolve the latter problem, populate the pre_shutdown pointer in the watchdog timer hwmod classes with a function that executes the watchdog shutdown sequence. This allows the hwmod code to fully disable the watchdog. Then, to allow some board files to support watchdog coverage throughout kernel initialization, add common code to mach-omap2/io.c to cause the MPU watchdog to be disabled on boot unless a board file specifically requests it to remain enabled. Board files can do this by changing the watchdog timer hwmod's postsetup state between the omap2_init_common_infrastructure() and omap2_init_common_devices() function calls. 1.

* OMAP2+: hwmod: add postsetup statePaul Walmsley2010-12-221-12/+20
| | | | | | | | | | | | | | | | | | Allow board files and OMAP core code to control the state that some or all of the hwmods end up in at the end of _setup() (called by omap_hwmod_late_init() ). Reimplement the old skip_setup_idle code in terms of this new postsetup state code. There are two use-cases for this patch: the !CONFIG_PM_RUNTIME case, in which all IP blocks should stay enabled after _setup() finishes; and the MPU watchdog case, in which the watchdog IP block should enter idle if watchdog coverage of kernel initialization is desired, and should be disabled otherwise.

* OMAP2+: io: split omap2_init_common_hw()Paul Walmsley2010-12-221-4/+12
| | | | | | | | | | | | | | | | | | | | | Split omap2_init_common_hw() into two functions. The first, omap2_init_common_infrastructure(), initializes the hwmod code and data, the OMAP PM code, and the clock code and data. The second, omap2_init_common_devices(), handles any other early device initialization that, for whatever reason, has not been or cannot be moved to initcalls or early platform devices. This patch is required for the hwmod postsetup patch, which allows board files to change the state that hwmods should be placed into at the conclusion of the hwmod _setup() function. For example, for a board whose creators wish to ensure watchdog coverage across the entire kernel boot process, code to change the watchdog's postsetup state will be added in the board-*.c file between the omap2_init_common_infrastructure() and omap2_init_common_devices() function calls.
