* ARM: S5PV210: Correct clock register propertiesMyungJoo Ham2010-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Corrected shift values of I2S and UART clocks (CLK_GATE_IP3), which were defined incorrectly. 2. Corrected shift values of sclk_audio, uclk1, sclk_fimd, sclk_mmc, sclk_spi, sclk_pwm, which had duplicated .enable/.ctrlbit with their twins defined in struct clk init_clocks_disable[] and struct clk init_clocks[]. We've changed their .enable/.ctrlbit to use CLK_SRC_MASK register to avoid the duplicated clock problem described below. NOTE: Duplicated Clock Problem Please note that each clock definition should access different control register; otherwise, the system may suffer lockups. For example, if we have two clock definitions "a" and "b" which access the same register (and the shift value). Then, when we do: module A clk = clk_get("a"); clk->clk_enable(clk); module B (context switch) clk = clk_get("b"); clk->clk_enable(clk); do something with clk. clk->clk_disable(clk); module A (context switch) do something with clk * At this point, the system may hang. Therefore, there should be no clock definitions with the same contol register/shift. If we need to create "aliases", then, creating child clocks sharing the clock should be fine. 3. Corrected other sclk_* shift values and access registers.

* ARM: 6205/1: perf: ensure counter delta is treated as unsignedWill Deacon2010-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware performance counters on ARM are 32-bits wide but atomic64_t variables are used to represent counter data in the hw_perf_event structure. The armpmu_event_update function right-shifts a signed 64-bit delta variable and adds the result to the event count. This can lead to shifting in sign-bits if the MSB of the 32-bit counter value is set. This results in perf output such as: Performance counter stats for 'sleep 20': 18446744073460670464 cycles <-- 0xFFFFFFFFF12A6000 7783773 instructions # 0.000 IPC 465 context-switches 161 page-faults 1172393 branches 20.154242147 seconds time elapsed This patch ensures that the delta value is treated as unsigned so that the right shift sets the upper bits to zero.

After the v4l2 migration, the mt9m111 camera board information was not passed to the i2c layer anymore, but stored for future use of v4l2 (through soc_camera). Because mioa701_i2c_devices[] was tagged as "__initdata", and because after the v4l2 migration, the new structure "iclink" references it, the mt9m111 driver is not probed anymore, as part of "iclink" is not valid (discarded after kernel init).

* | | ARM: 6194/1: change definition of cpu_relax() for ARM11MPCoreWill Deacon2010-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux expects that if a CPU modifies a memory location, then that modification will eventually become visible to other CPUs in the system. On an ARM11MPCore processor, loads are prioritised over stores so it is possible for a store operation to be postponed if a polling loop immediately follows it. If the variable being polled indirectly depends on the outstanding store [for example, another CPU may be polling the variable that is pending modification] then there is the potential for deadlock if interrupts are disabled. This deadlock occurs in the KGDB testsuire when executing on an SMP ARM11MPCore configuration. This patch changes the definition of cpu_relax() to smp_mb() for ARMv6 cores, forcing a flushing of the write buffer on SMP systems before the next load takes place. If the Kernel is not compiled for SMP support, this will expand to a barrier() as before.

However, the workaround is only valid on CPUs that do not do speculative loads into the D-cache. This patch adds a Kconfig option with the corresponding help to make the above clear. When the DMA_CACHE_RWFO option is disabled, the kernel behaviour is that prior to the f4d6477f commit. This also allows ARMv6 UP processors with speculative loads to work correctly. For other processors, a different workaround may be needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent patch for DMA cache maintenance on ARM11MPCore added a write for ownership trick to the v6_dma_inv_range() function. Such operation destroys data already present in the buffer. However, this function is used with with dma_sync_single_for_device() which is supposed to preserve the existing data transfered into the buffer. This patch adds a combination of read/write for ownership to preserve the original data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel timer queue is being run currently from a GP timer running in a one shot mode, which works in a way that when it expires, it will also stop. Usually during this situation, the interrupt handler will ack the interrupt, load a new value to the timer and start it again. During suspend, the situation is slightly different, as we disable interrupts just before timekeeping is suspended, which leaves a small window where the timer can expire before it is stopped, and will leave the interrupt flag pending. This pending interrupt will prevent ARM sleep entry, thus now we ack it always when we are attempting to stop a timer.

This helps find bad usages such as dereferences after the unmap, or overflow into the adjacent fixmap areas. But this debugging aid is completely bypassed when a kmap for the same page already exists as the kmap is reused instead. ON VIVT systems we have no choice but to reuse that kmap due to cache coherency issues, but on non VIVT systems we should always force the fixmap usage when debugging is active.

| * | ARM: 6146/1: sa1111: Prevent deadlock in resume pathMarek Vašut2010-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reorganises the sa1111_resume() function in a manner the spinlock happens after calling the sa1111_wake(). This fixes two bugs: 1) This function called sa1111_wake() which tried to claim the same spinlock the sa1111_resume() already claimed. This would result in certain deadlock. Original idea for this part: Russell King <rmk+kernel@arm.linux.org.uk> 2) The function didn't unlock the spinlock in case the chip didn't report correct ID.

| * | ARM: 6145/1: ux500 MTU clockrate correctionLinus Walleij2010-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adjusts the clockrate for the MTU timer. On the different UX500 variants this rate is different. The platform can also have been set up at hardware initialization, bootloader or early init for different clock speeds. To have the clock framework available early so the timers can use them, the clock initialization for Nomadik and ux500 is moved to IRQ init time. A custom per-clock callback is added to handle special cases like this. This solves a user-visible bug: without this patch the current UX500 platforms will not be synchronized to wall-clock time and the platform will drift in time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a bug in mm/init.c when freeing the TCM compile memory, this was being referred to as a char * which is incorrect: this will dereference the pointer and feed in the value at the location instead of the address to it. Change it to a plain char and use &(char) to reference it.
