* ARM: omap3: enable off mode automaticallyAndreas Kemnade2020-09-241-2/+0
| | | | | | | | | | | | | | | Enabling off mode was only reachable deeply hidden in the debugfs. As powersaving is an important feature, move the option out of its shady place. The debugfs file can still be used to override the default. Use the presence of a device compatible to ti,twl4030-idle or ti,twl4030-idle-osc-off as an indicator that the board is wired correctly for off mode.

* ARM: OMAP2+: Drop unused pm-noopTony Lindgren2018-04-161-5/+0
| | | | | | | | | | | | | | | | | | | | | | Looks like these functions don't do anything in the mainline kernel so we can just drop it. Note that we must now also remove ir-rx51 pdata as it relies on the dummy platform data that does not do anything. And ir-rx51 is calling a pdata callback that doesn't do anything without checking if it exists first. For configuring device specific minimal latencies, the interface to use is pm_qos_add_request(). For an example, see what was done in commit 9834ffd1ecc3 ("ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent glitches"). I've added some comments to ir-rx51 so people using it can add pm_qos support and test it.

| | | | | | | | | | | | | | | | | | | | | | | | Debugfs functions return NULL when they fail, or an error pointer when not configured. The intention behind the error pointer is that it appears as a valid pointer to the caller, and so the caller continues inspite of debugfs not being available. Debugfs failure should only ever be checked with (!ptr) and not the IS_ERR*() functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Tested on 36xx/Zoom3 using MMC driver, which is currently the only in-tree user of this API. This patch should be reverted after all devices are converted to using omap_device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* OMAP3 PM: Adding counters for power domain logic off and mem off during ↵Thara Gopinath2010-02-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | retention. This patch adds counters to keep track of whether the powerdomain logic or software controllable memory banks are turned off when the power domain enters retention. During power domain retention if logic gets turned off, the scenario is known as Open Switch Retention. Also during retention s/w controllable memory banks of a power domain can be chosen to be kept in retention or off. This patch adds one counter per powerdomain to track the power domain logic state during retention. Number of memory bank state counters added depends on the number of software controllable memory banks of the powerdomain.

* OMAP clockdomain/powerdomain: remove runtime register/unregisterPaul Walmsley2010-01-271-1/+1
| | | | | | | | | | | | | | OMAP clockdomains and powerdomains are currently defined statically, only registered at boot, and never unregistered, so we can remove the unregister function and the locking. A variant of this was originally suggested a while ago by Dmitry Baryshkov <dbaryshkov@gmail.com>. This version of this patch contains an additional fix from Kevin Hilman <khilman@deeprootsystems.com> to address one of the pwrdm_for_each_nolock() users in mach-omap2/pm-debug.c. Thanks Kevin.

* ARM: OMAP4: PM: Make OMAP3 Clock-domain framework compatible for OMAP4.Abhijit Pagare2010-01-271-2/+2
| | | | | | | | | | | | | | Here the ".clkstctrl_reg" field is added to the clockdomain stucture as the module offsets for OMAP4 do not map one to one for powerdomains and clockdomains as it used to for OMAP3. Hence we need to use absolute addresses to access the control registers. Some of the clock domains have modules falling in the address space of PRM partition. Hence necessitating the use of absolute adresses.
