2013-08-23ARM: OMAP: TI81XX: add always-on powerdomain for TI81XXAida Mynzhasova
This patch adds alwon powerdomain support for TI81XX, which is required for stable functioning of a big number of TI81XX subsystems. Signed-off-by: Aida Mynzhasova <aida.mynzhasova@skitlab.ru> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2013-06-18ARM: OMAP: TI816X: add powerdomains for TI816xAida Mynzhasova
This patch adds required structures for powerdomain initialization on the ti816x. It is impossible to use omap3430 structures in order to initialize powerdomains on ti816x, because there are big differences between PRCM module base address offsets on these CPUs.

2013-01-29ARM: OMAP2+: powerdomain: fix whitespace, improve flag commentsPaul Walmsley
Fix some whitespace problems introduced by commit da03ce65b5431245b9cd20db3edaaa6b9f5c8dc1 ("OMAP3: powerdomain data: add voltage domains"). Also, improve the documentation for the struct powerdomain.flags field. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com>
2012-09-12ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+Tony Lindgren
As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

2012-06-28arm: omap3: am35x: Set proper powerdomain statesMark A. Greer
The am35x family of SoCs only support the PWRSTS_ON state so create a new set of powerdomain structures that ensure that only the ON state is entered. Signed-off-by: Mark A. Greer <mgreer@animalcreek.com>
2012-05-10ARM: OMAP: AM35xx: convert 3517 detection/flags to AM35xxKevin Hilman
Currently cpu_is_omap3517() actually detects any device in the AM35x family (3517 and no-SGX version 3505.) To make it more clear what is being detected, convert the names from 3517 to AM35xx. This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517(). In order to avoid cross-tree dependencies with clock-tree changes, cpu_is_omap3517() is left until the clock changes are merged, at which point cpu_is_omap3517() will be completely removed.

2011-09-14OMAP: powerdomain: remove omap_chip bitmasksPaul Walmsley
At Tony's request, remove the omap_chip bitmasks from the powerdomain definitions. Instead, initialize powerdomains based on one or more lists that are applicable to a particular SoC family, variant, and silicon revision.

2011-09-14OMAP: powerdomain: split pwrdm_init() into two functionsPaul Walmsley
In preparation for OMAP_CHIP() removal, split pwrdm_init() into three functions. This allows some of them to be called multiple times: for example, pwrdm_register_pwrdms() can be called once to register powerdomains that are common to a group of SoCs, and once to register powerdomains that are specific to a single SoC. The appropriate order to call these functions - which is enforced by the code - is: 1. pwrdm_register_platform_funcs() 2. pwrdm_register_pwrdms() (can be called multiple times) 3. pwrdm_complete_init() Convert the OMAP2, 3, and 4 powerdomain init code to use these new functions. While here, improve documentation, and increase CodingStyle conformance by shortening some local variable names. Signed-off-by: Paul Walmsley <paul@pwsan.com>

2011-03-07OMAP2+: powerdomain: fix bank power state bitfieldsPaul Walmsley
The bank power state bitfields in the powerdomain data are encoded incorrectly. These fields are intended to be bitfields, representing a set of power states that the memory banks support. However, when only one power state was supported by a given bank, the field was incorrectly set to the bit shift -- not the mask. While here, update some file copyrights. The OMAP4 autogeneration scripts have been updated accordingly.

2010-12-21OMAP2+: powerdomain: move header file from plat-omap to mach-omap2Paul Walmsley
The OMAP powerdomain code and data is all OMAP2+-specific. This seems unlikely to change any time soon. Move plat-omap/include/plat/powerdomain.h to mach-omap2/powerdomain.h. The primary point of doing this is to remove the temptation for unrelated upper-layer code to access powerdomain code and data directly. As part of this process, remove the references to powerdomain data from the GPIO "driver" and the OMAP PM no-op layer, both in plat-omap. Change the DSPBridge code to point to the new location for the powerdomain headers. The DSPBridge code should not be including the powerdomain headers; these should be removed.

2010-12-21OMAP2/3: PRCM: split OMAP2/3-specific PRCM code into OMAP2/3-specific filesPaul Walmsley
In preparation for adding OMAP4-specific PRCM accessor/mutator functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was OMAP2xxx/3xxx-specific. This process also requires the #includes in each of these files to be changed to reference the new file name. As part of doing so, add some comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use "sideways includes", to indicate that these users of the PRM/CM includes should not be doing so.

2010-12-21OMAP2+: powerdomains: move powerdomain static data to .c filesPaul Walmsley
Static data should be declared in .c files, not .h files. It should be possible to #include .h files at any point without creating multiple copies of the same data. We converted the clock data to .c files some time ago. This patch does the same for the powerdomain data.
