* ARM: OMAP3+: am33xx id: Add new am33xx specific function to check dev_featureVaibhav Hiremath2013-06-18
| | | | | | | | | | | Layout of DEV_FEATURE register (offset = 0x604) is different between TI81xx and AM33xx device, so create separate function which will check for features available on specific AM33xx SoC and set the flags accordingly.

* | ARM: AM33XX: cm: Add bit-field width valuesVaibhav Hiremath2012-09-22
|/ | | | | | | | | | | | | | | | | The new common clk framework includes basic definitions for mux and divider clocks. These definitions depend on shift and width values instead of the pre-computed masks that the OMAP/AM33XX clk framework has traditionally used when accessing the register to control the mux or divisor. To ease this transition the masks are left intact and the width field is simply added alongside the shift and mask data.

| * ARM: OMAP2+: control: new APIs to configure boot address and modeOmar Ramirez Luna2012-06-18
|/ | | | | | | | | | | | | | | | | | | 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>

* ARM: OMAP: TI81XX: Prepare for addition of TI814X supportHemant Pedanekar2011-12-13
| | | | | | | | | | | | | | | | | 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: pm: omap34xx: remove get_*_restore_pointer functions, directly use ↵Kevin Hilman2011-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | entry points Upon return from off-mode, the ROM code jumps to a restore function saved in the scratchpad. Based on SoC revision or errata, this restore entry point is different. Current code uses some helper functions in sleep34xx.S (get_*_restore_pointer) to get the restore function entry point. When returning from off-mode, this code is executed from SDRAM, so there's no reason to use these helper functions when using the SDRAM entry points directly would work just fine. This patch uses ENTRY/ENDPROC to create "real" entry points for these functions, and uses those values directly when writing the scratchpad. Tested all three entry points - restore_es3: 3430/n900 - restore_3630: 3630/Zoom3 - restore: 3530/Overo Suggested-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Jean Pihet <j-pihet@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds voltage driver support for OMAP3. The driver allows configuring the voltage controller and voltage processors during init and exports APIs to enable/disable voltage processors, scale voltage and reset voltage. The driver maintains the global voltage table on a per VDD basis which contains the various voltages supported by the VDD along with per voltage dependent data like smartreflex efuse offset, errminlimit and voltage processor errorgain. The driver also allows the voltage parameters dependent on the PMIC to be passed from the PMIC file through an API. The driver allows scaling of VDD voltages either through "vc bypass method" or through "vp forceupdate method" the choice being configurable through the board file. This patch contains code originally in linux omap pm branch smartreflex driver. Major contributors to this driver are Lesly A M, Rajendra Nayak, Kalle Jokiniemi, Paul Walmsley, Nishant Menon, Kevin Hilman. The separation of PMIC parameters into a separate structure which can be populated from the PMIC file is based on the work of Lun Chang from Motorola in an internal tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the padconf save code from pm34xx.c to the System Control Module code in mach-omap2/control.c. This is part of the general push to move direct register access from middle-layer core code to low-level core code, so the middle-layer code can be abstracted to work on multiple platforms and cleaned up. In the medium-to-long term, this code should be called by the mux layer code, not the PM idle code. This is because, according to the TRM, saving the padconf only needs to be done when the padconf changes[1].

| | | | | | | | | | | | | | | | | | | | | | | | | Erratum id: i608 RTA (Retention Till Access) feature is not supported and leads to device stability issues when enabled. This impacts modules with embedded memories on OMAP3630 Workaround is to disable RTA on boot and coming out of core off. For disabling RTA coming out of off mode, we do this by overriding the restore pointer for 3630 as the first point of entry before caches are touched and is common for GP and HS devices. To disable earlier than this could be possible by modifying the PPA for HS devices, but not for GP devices.

* OMAP: control: move plat-omap/control.h to mach-omap2/control.hPaul Walmsley2010-10-08
Only OMAP2+ platforms have the System Control Module (SCM) IP block. In the past, we've kept the SCM header file in plat-omap. This has led to abuse - device drivers including it; includes being added that create implicit dependencies on OMAP2+ builds; etc. In response, move the SCM headers into mach-omap2/. As part of this, remove the direct SCM access from the OMAP UDC driver. It was clearly broken. The UDC code needs an indepth review for use on OMAP2+ chips.
