* | | | omap_hsmmc: Move gpio and regulator control from board fileAdrian Hunter2010-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the setup code for GPIO's and Voltage Regulators from the board file mmc-twl4030.c to the driver omap_hsmmc.c. PBIAS and other system control configuration remains in the board file. Moving GPIO code to the driver makes the board initialisation code independent of when GPIO's are defined. That makes the board initialisation now entirely independent of its original twl4030 roots. Moving Voltage Regulator code to the driver allows for further development of regulator support in the core MMC code. It also permits the MMC core to be compiled as a module, because the board code no longer calls MMC core functions.

* | | | omap3: SDP: Introducing 'board-sdp-flash.c' for flash initVimal Singh2010-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds 'board-sdp-flash.c', which could be utilized by boards similar to 3430SDP. (For ex: 2430sdp, 36030sdp). This file does initialization for all three flash devices present in SDP boards (NOR, NAND, OneNAND), by finding there 'cs' number dynamically using switch setting information (S8: 1-4). This also expects partition information from core board files (for ex: board-3430sdp.c). Which allows to choose different default partitions for different boards. A new structure is created for this purpose: 'flash_partitions' in 'mach/board-sdp.h'. This has two members: 1. struct mtd_partition *parts 2. int nr_parts A board file is expected to fill this structure and pass it to 'sdp-flsash-init'. Partition information should be passed in structure array of 'flash_partitions'. Partition information should be passed in below sequence in array: NOR OneNAND NAND Signed-off-by: Vimal Singh <vimalsingh@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

* | | | omap: McBSP: Use cache when modifying individual register bitsJanusz Krzysztofik2010-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the way McBSP registers are updated: use cached values instead of relying upon those read back from the device. With this patch, I have finally managed to get rid of all random playback/recording hangups on my OMAP1510 based Amstrad Delta hardware. Before that, values read back from McBSP registers to be used for updating them happened to be errornous. From the hardware side, the issue appeared to be caused by a relatively high power requirements of an external USB adapter connected to the board's printer dedicated USB port. I think there is one important point that makes this patch worth of applying, apart from my hardware quality. With the current code, if it ever happens to any machine, no matter if OMAP1510 or newer, to read incorrect value from a McBSP register, this wrong value will get written back without any checking. That can lead to hardware damage if, for example, an input pin is turned into output as a result. Applies on top of patch 3 from this series: [PATCH v9 3/4] OMAP: McBSP: Introduce caching in register write operations Tested on OMAP1510 based Amstrad Delta using linux-omap for-next, commit fb7380d70e041e4b3892f6b19dff7efb609d15a4 (2.6.33-rc3+ dated 2010-01-11).

* | | | OMAP: omap_device: optionally auto-adjust device activate/deactivate latenciesKevin Hilman2010-01-26

Here the worst-case measured latencies for the activate and deactivate hooks are stored. In addition, add an option to auto-adjust the latency values used for device activate/deactivate. By setting a new 'OMAP_DEVICE_LATENCY_AUTO_ADJUST' flag in the omap_device_pm_latency struct, the omap_device layer automatically adjusts the activate/deactivate latencies to the worst-case measured values. Anytime a new worst-case value is found, it is printed to the console. Here is an example log during boot using UART2 s an example. After boot, the OPP is manually changed to the 125MHz OPP: [...] Freeing init memory: 128K omap_device: serial8250.2: new worst case deactivate latency 0: 30517 omap_device: serial8250.2: new worst case activate latency 0: 30517 omap_device: serial8250.2: new worst case activate latency 0: 218139648 omap_device: serial8250.2: new worst case deactivate latency 0: 61035 omap_device: serial8250.2: new worst case activate latency 0: 278076171 omap_device: serial8250.2: new worst case activate latency 0: 298614501 omap_device: serial8250.2: new worst case activate latency 0: 327331542 / # echo 125000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed omap_device: serial8250.2: new worst case deactivate latency 0: 91552 Motivation: this can be used as a technique to automatically determine the worst case latency values. The current method of printing a warning on every violation is too noisy to actually interact the console in order to set low OPP to discover latencies. Another motivation for this patch is that the activate/deactivate latenices can vary depending on the idlemode of the device. While working on the UARTs, I noticed that when using no-idle, the activate latencies were as high as several hundred msecs as shown above. When the UARTs are in smart-idle, the max latency is well under 100 usecs. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

In the current situation, if several functions add dependencies on the same clockdomains, when the first dependency removal function is called, the dependency will be incorrectly removed from the hardware. Add clkdm_clear_all_wkdeps() and clkdm_clear_all_sleepdeps(), which provide a fast and usecounting-consistent way to clear all hardware clockdomain dependencies, since accesses to these registers can be quite slow. pm{2,3}4xx.c has been updated to use these new functions. The original version of this patch did not touch these files, which previously wrote directly to the wkdep registers, and thus confused the usecounting code. This problem was found by Kevin Hilman <khilman@deeprootsystems.com>. N.B.: This patch introduces one significant functional difference over the previous pm34xx.c code: sleepdeps are now cleared during clockdomain initialization, whereas previously they were left untouched. This has been tested by Kevin and confirmed to work. The original version of this patch also did not take into consideration that some clockdomains do not have sleep or wakeup dependency sources, which caused NULL pointer dereferences. This problem was debugged and fixed by Kevin Hilman <khilman@deeprootsystems.com>.

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

* | | OMAP2/3: DMTIMER: Clear pending interrupts when stopping a timerTero Kristo2010-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP GP timers keep running for a few cycles after they are stopped, which can cause the timer to expire and generate an interrupt. The pending interrupt will prevent e.g. OMAP from entering suspend, thus we ack it manually. Only applicable on OMAP2/3/4.

| * | | OMAP: timekeeping: time should not stop during suspendKevin Hilman2010-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During suspend, the kernel timekeeping subsystem is shut down. Before suspend and upon resume, it uses a weak function read_persistent_clock() to determine the amount of time that elapsed during suspend. This function was not implemented on OMAP, so from the timekeeping subsystem perspective (and thus userspace as well) it appeared that no time elapsed during suspend. This patch uses the 32k sync timer as a the persistent clock. NOTE: This does *NOT* fully handle wrapping of the 32k sync timer, so more than one wrapping of the 32k sync timer during suspend may cause problems. Also note there are not interrupts when the 32k sync timer wraps, so something else has to be done.

| * | | OMAP3: PM: Disable interrupt controller AUTOIDLE before WFITero Kristo2010-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP interrupt controller goes to unknown state when there is right combination of l3,l4 sleep/wake-up transitions, l4 autoidle in interrupt controller and some interrupt. When this happens, interrupts are not delivered to ARM anymore and ARM will remain in WFI (wait for interrupt) until interrupt controller is forced to wake-up (i.e. lauterbach).
