2010-09-27omap4: control: Fix the control module register accessesSantosh Shilimkar
This patch has multiple fixes together. To ensure that git bisect work across commits, all changes are clubbed together 1. Move the common control base address to control core 2. Remove the manually coeded defines and use the ones from headers. 3. Fix the the status register define in id.c for OMAP4 4. Fix all the register define in hsmmc.c 5.

2010-09-27omap4: control: Add ctrl_pad_base to omap_globalsSantosh Shilimkar
On omap4 control module is divided in four IP blocks. - CTRL_MODULE_CORE 0x4a002000 - CTRL_MODULE_PAD_CORE 0x4a100000 - CTRL_MODULE_WKUP 0x4a30c000 - CTRL_MODULE_PAD_WKUP 0x4a31e000 Addressing all the modules with single base address is not possible considering 16 bit offsets. The mux code manages the pad core and pad wakeup related base address inside the mux framework. For other usage only control core and control pad bases are necessary. So this patch maps only needed pad control base address which is used by device drivers and infrastructure code The main control core base is still kept same in this patch to keep git-bisect working. This will be fixed in the relevant patch in this series.

Currently we map 1 MB section while setting up SRAM on OMAPs Regardless of the actual memory. The physical OCM RAM available on OMAP SOCs is in order of KBs. This patch maps only available sram and cleans up some un-necessary cpu_is_xxx checks. Mapping un-available or non-accessible(secure) memory on the newer ARM processor is dangerous. Because ARM CPUs can now speculatively prefetch, we should avoid mapping any no-existing or secure memory.

Currently there is a bug in the existing omap_device core code when extracting the hwmod structures passed to omap_device_build_ss(). This bug gets exposed only when passing multiple hwmod structures to omap_device_build_ss() resulting in incorrect extraction from second hwmod structure.

2010-09-23OMAP: GPIO: ensure debounce clocks are disabled during idle/suspendKevin Hilman
If a GPIO bank has more than one GPIO with debounce enabled, the debounce clock will not be fully disabled before going to idle/suspend. In the idle path, we just do a single clk_disable() of the bank's debounce clock. If there are multiple debounce-enabled GPIOs in the bank, that clocks usage count will be > 1, so the clk_disable() will not actually disable the clock. So the fix is to clk_disable() for every debounce-enabled GPIO in the bank (and an equivalent clk_enable() of course.) Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

2010-09-23OMAP: omap_device: make all devices a child of a new parent deviceKevin Hilman
In order to help differentiate omap_devices from normal platform_devices, make them all a parent of a new common parent device. Then, in order to determine if a platform_device is also an omap_device, checking the parent is all that is needed. Users of this feature are the runtime PM core for OMAP, where we need to know if a device being passed in is an omap_device or not in order to know whether to call the omap_device API with it. In addition, all omap_devices will now show up under /sys/devices/omap instead of /sys/devices/platform Acked-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-09-23Revert "OMAP: omap_device: add omap_device_is_valid()"Kevin Hilman
This reverts commit 0007122ad85cc36b1c18c0b59344093ca210d206. The dereference method of checking for a valid omap_device when wrapping a platform_device is rather unsafe and dangerous. Instead, a better way of checking for a valid omap-device is to use a common parent device for all omap_devices, then a check can simply be made using the device parent. The only user of this API was the initial version of the runtime PM core for OMAP. This has now been switched to check device parent, so there are no more users of this API.

The function is called from within the framework inside omap_device_build_ss(), after omap_device_register. This allows drivers to get a pointer to its optional clocks based on its role by calling clk_get(<dev*>, <role>).

2010-09-21OMAP: hwmod: Fix softreset for modules with optional clocksBenoit Cousson
Some modules (like GPIO, DSS...) require optionals clock to be enabled in order to complete the sofreset properly. Add a HWMOD_CONTROL_OPT_CLKS_IN_RESET flag to force all optional clocks to be enabled before reset. Disabled them once the reset is done. TODO: For the moment it is very hard to understand from the HW spec, which optional clock is needed and which one is not. So the current approach will enable all the optional clocks. Paul proposed a much finer approach that will allow to tag only the needed clock in the optional clock table. This might be doable as soon as we have a clear understanding of these dependencies.

2010-09-21OMAP: hwmod: Fix softreset status check for some new OMAP4 IPsBenoit Cousson
In OMAP3 a specific SYSSTATUS register was used to get the softreset status. Starting in OMAP4, some IPs does not have SYSSTATUS register and instead use the SYSC softreset bit to provide the status. Other cases might exist: - Some IPs like McBSP does have a softreset control but no reset status. - Some IPs that represent subsystem, like the DSS, can contains a reset status without softreset control. The status is the aggregation of all the sub modules reset status. - Add a new flag (SYSC_HAS_RESET_STATUS) to identify the new programming model and replace the previous SYSS_MISSING, that was used to flag IP with softreset control but without the SYSSTATUS register, with a specific SYSS_HAS_RESET_STATUS flag. - MCSPI and MMC contains both programming models, so the legacy one will be prevented by removing the syss offset field that become useless.

2010-09-21OMAP: hwmod: Add hardreset management supportBenoît Cousson
Most processor IPs does have a hardreset signal controlled by the PRM. This is different of the softreset used for local IP reset from the SYSCONFIG register. The granularity can be much finer than orginal HWMOD, for ex, the IVA hwmod contains 3 reset lines, the IPU 3 as well, the DSP 2... Since this granularity is needed by the driver, we have to ensure than one hwmod exist for each hardreset line. - Store reset lines as hwmod resources that a driver can query by name like an irq or sdma line. - Add two functions for asserting / deasserting reset lines in hwmods processor that require manual reset control. - Add one functions to get the current reset state. - If an hwmod contains only one line, an automatic assertion / de-assertion is done. -> de-assert the hardreset line only during enable from disable transition -> assert the hardreset line only during shutdown Note: The hwmods with hardreset line and HWMOD_INIT_NO_RESET flag must be kept in INITIALIZED state. They can be properly enabled only if the hardreset line is de-asserted before.

2010-08-12ASoC: multi-component - ASoC Multi-Component SupportLiam Girdwood
This patch extends the ASoC API to allow sound cards to have more than one CODEC and more than one platform DMA controller. This is achieved by dividing some current ASoC structures that contain both driver data and device data into structures that only either contain device data or driver data. i.e. struct snd_soc_codec ---> struct snd_soc_codec (device data) +-> struct snd_soc_codec_driver (driver data) struct snd_soc_platform ---> struct snd_soc_platform (device data) +-> struct snd_soc_platform_driver (driver data) struct snd_soc_dai ---> struct snd_soc_dai (device data) +-> struct snd_soc_dai_driver (driver data) struct snd_soc_device ---> deleted This now allows ASoC to be more tightly aligned with the Linux driver model and also means that every ASoC codec, platform and (platform) DAI is a kernel device. ASoC component private data is now stored as device private data. The ASoC sound card struct snd_soc_card has also been updated to store lists of it's components rather than a pointer to a codec and platform. The PCM runtime struct soc_pcm_runtime now has pointers to all its components. This patch adds DAPM support for ASoC multi-component and removes struct snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec or runtime PCM level basis rather than using snd_soc_socdev. Other notable multi-component changes:- * Stream operations now de-reference less structures. * close_delayed work() now runs on a DAI basis rather than looping all DAIs in a card. * PM suspend()/resume() operations can now handle N CODECs and Platforms per sound card. * Added soc_bind_dai_link() to bind the component devices to the sound card. * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove DAI link components. * sysfs entries can now be registered per component per card. * snd_soc_new_pcms() functionailty rolled into dai_link_probe(). * snd_soc_register_codec() now does all the codec list and mutex init. This patch changes the probe() and remove() of the CODEC drivers as follows:- o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec().
