2011-08-10arch:arm:plat-omap:iovmm: remove unused variable 'va'Maxin John
The pointer "va" returned from "phys_to_virt(pa)" is never used in "sgtable_fill_kmalloc()".So,it is safe to remove this set-but-unused variable. Signed-off-by: Maxin B. John <maxin.john@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2011-07-12OMAP: PM: omap_device: add system PM methods for PM domain handlingKevin Hilman
In the omap_device PM domain callbacks, use omap_device idle/enable to automatically manage device idle states during system suspend/resume. If an omap_device has not already been runtime suspended, the ->suspend_noirq() method of the PM domain will use omap_device_idle() to idle the HW after calling the driver's ->runtime_suspend() callback. Similarily, upon resume, if the device was suspended during ->suspend_noirq(), the ->resume_noirq() method of the PM domain will use omap_device_enable() to enable the HW and then call the driver's ->runtime_resume() callback. If a device has already been runtime suspended, the noirq methods of the PM domain leave the device runtime suspended by default. However, if a driver needs to runtime resume a device during suspend (for example, to change its wakeup settings), it may do so using pm_runtime_get* in it's ->suspend() callback.

2011-07-11ASoC: omap: McBSP: fix build breakage on OMAP1Paul Walmsley
After commits d13586574d373ef40acd4725c9a269daa355e412 ("OMAP: McBSP: implement functional clock switching via clock framework") and cf4c87abe238ec17cd0255b4e21abd949d7f811e ("OMAP: McBSP: implement McBSP CLKR and FSR signal muxing via mach-omap2/mcbsp.c"), any OMAP1 board (such as the AMS Delta) that uses the ASoC McBSP driver will no longer build: sound/built-in.o: In function `omap_mcbsp_dai_set_dai_sysclk': last.c:(.text+0x24ff8): undefined reference to `omap2_mcbsp1_mux_clkr_src' last.c:(.text+0x2500c): undefined reference to `omap2_mcbsp1_mux_fsr_src' make: *** [vmlinux] Error 1 Fix by defining three OMAP1-only dummy functions for omap2_mcbsp1_mux_clkr_src(), omap2_mcbsp1_mux_fsr_src(), and omap2_mcbsp_set_clks_src(). Normally, code that is OMAP SoC-revision-specific like this should go under the arch/arm/*omap* directories, and get abstracted away from drivers via struct platform_data function pointers. This doesn't work in this case since there doesn't appear to be any convenient way to access struct platform_data (or something like it) in the current design of the sound/soc/omap/omap-mcbsp.c driver. Reported by Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> and Tony Lindgren <tony@atomide.com>. Janusz also posted a patch to fix this at: http://www.spinics.net/lists/linux-omap/msg39560.html (among other places), but the following approach seems less dependent on compiler behavior. This patch passes build tests for ams_delta_defconfig and omap2plus_defconfig, but since I don't have an AMS Delta here, I can't boot test it on that platform.

clocksource support. This achieves several things: 1. It means we get rid of all these helper functions which frankly should never have been necessary. 2. It means omap_readl() inside these helper functions does not appear in ftrace output. Another plus is that we avoid the overhead of calculating the address to read each time, but a minus is that we use readl() which has a barrier.

Add a debugfs node called "summary" to /sys/kernel/debug/clock/ that displays a quick summary of all clocks registered in the "clocks" structure. The format of the output from this node is: <clock-name> <parent-name> <rate> <usecount> This debugfs node was very helpful for taking a quick snapshot of the linux clock tree for OMAP and ensuring clock frequencies calculated by the kernel were indeed correct.

2011-07-10OMAP4: hwmod data: Add modulemode entry in omap_hwmod structureBenoit Cousson
Add a new field to provide the mode supported by the module. The mode will control the way mandatory clocks are managed by the PRCM. 0 : Module is temporarily disabled by SW. OCP access to module are stalled. Can be used to change timing parameter of GPMC module. 1 : Module is managed automatically by HW according to clock domain transition. A clock domain sleep transition put module into idle. A wakeup domain transition put it back into function. If CLKTRCTRL=3, any OCP access to module is always granted. Module clocks may be gated according to the clock domain state. 2 : Module is explicitly enabled. Interface clock (if not used for functions) may be gated according to the clock domain state. Functional clocks are guarantied to stay present. As long as in this configuration, power domain sleep transition cannot happen. Some modules will have a modulemode initialized at 1 (HWCTRL) by default. This is the case for interconnect and simple module like GPIO, WDT, MAILBOX.

2011-07-10OMAP4: hwmod data: Add clock domain attributeBenoit Cousson
In OMAP PRCM terminology, the clock domain is defined as a group of IPs that share some clocks and most of the time an interface clock. Every IP does belong to a clockdomain. For the moment the clock domain attribute is affected to a clock node. The issue with that approach, is that a clock might or not belong to a clock domain. Moreover during module transition, it is up to a module to handle properly the clock domain state and not to a clock node. Create a clkdm_name attribute to provide this information per hwmod. Populate this attribute for every OMAP4 hwmod entries. Future cleanup series with remove that information from the OMAP4 clock when it is relevant.

2011-07-10OMAP: hwmod: fix the i2c-reset timeout during bootupAvinash.H.M
The sequence of _ocp_softreset doesn't work for i2c. The i2c module has a special sequence to reset the module. The sequence is - Disable the I2C. - Write to SOFTRESET bit. - Enable the I2C. - Poll on the RESETDONE bit. The sequence is implemented as a function and the i2c_class is updated with the correct 'reset' pointer. omap_hwmod_softreset function is implemented which triggers the softreset by writing into sysconfig register. On following this sequence, i2c module resets properly and timeouts are not seen.

2011-07-10I2C: OMAP2+: increase omap_i2c_dev_attr flags from u8 to u32Andy Green
As part of removing cpu_...() from the OMAP I2C driver, we need to convert the CPU tests into functionality flags that are set by hwmod class in the same way the IP revision is. More flags are needed than will fit in the existing u8 flags member of omap_i2c_dev_attr. These flags can refer to options inside the IP block but they are most needed for information about cpu implementation specific options that are not part of the IP block itself. For example, how the CPU data bus is wired to the IP block databus differs between OMAP cpus and affects how you must shift the address in the IP block, but is not a feature of the IP block itself.

2011-07-09OMAP: omap_device: replace _find_by_pdev() with to_omap_device()Kevin Hilman
The omap_device layer currently has two ways of getting an omap_device pointer from a platform_device pointer. Replace current usage of _find_by_pdev() with to_omap_device() since to_omap_device() is more familiar to the existing to_platform_device() used when getting a platform_device pointer from a struct device pointer.

The DPLL USB can generate higher speed (x2) than the regular ones. The max multiplication value is then twice the previous value. Fix both max_mult and max_div with that correct values. Change the max_div variable type to u16 to allow storing up to 256. Replace as well the define with the value to avoid unneeded indirection and provide a better readability. Remove the defines that become useless.

2011-07-09omap_hwmod: use a terminator record with omap_hwmod_dma_info arraysPaul Walmsley
Previously, struct omap_hwmod_dma_info arrays were unterminated; and users of these arrays used the ARRAY_SIZE() macro to determine the length of the array. However, ARRAY_SIZE() only works when the array is in the same scope as the macro user. So far this hasn't been a problem. However, to reduce duplicated data, a subsequent patch will move common data to a separate, shared file. When this is done, ARRAY_SIZE() will no longer be usable. This patch removes ARRAY_SIZE() usage for struct omap_hwmod_dma_info arrays and uses a sentinel value (irq == -1) as the array terminator instead. Signed-off-by: Paul Walmsley <paul@pwsan.com>

2011-07-09OMAP2+: hwmod: Fix smart-standby + wakeup supportBenoit Cousson
The commit 86009eb326afde34ffdc5648cd344aa86b8d58d4 was adding the wakeup support for new OMAP4 IPs. This support is incomplete for busmaster IPs that need as well to use smart-standby with wakeup. This new standbymode is suported on HSI and USB_HOST_FS for the moment. Add the new MSTANDBY_SMART_WKUP flag to mark the IPs that support this capability. Enable this new mode when applicable in _enable_wakeup, _disable_wakeup, _enable_sysc and _idle_sysc. The omap_hwmod_44xx_data.c will have to be updated to add this new flag.
