2009-02-17[ARM] 5401/1: Orion: fix edge triggered GPIO interrupt supportNicolas Pitre5-53/+29
The GPIO interrupts can be configured as either level triggered or edge triggered, with a default of level triggered. When an edge triggered interrupt is requested, the gpio_irq_set_type method is called which currently switches the given IRQ descriptor between two struct irq_chip instances: orion_gpio_irq_level_chip and orion_gpio_irq_edge_chip. This happens via __setup_irq() which also calls irq_chip_set_defaults() to assign default methods to uninitialized ones. The problem is that irq_chip_set_defaults() is called before the irq_chip reference is switched, leaving the new irq_chip (orion_gpio_irq_edge_chip in this case) with uninitialized methods such as chip->startup() causing a kernel oops. Many solutions are possible, such as making irq_chip_set_defaults() global and calling it from gpio_irq_set_type(), or calling __irq_set_trigger() before irq_chip_set_defaults() in __setup_irq(). But those require modifications to the generic IRQ code which might have adverse effect on other architectures, and that would still be a fragile arrangement. Manually copying the missing methods from within gpio_irq_set_type() would be really ugly and it would break again the day new methods with automatic defaults are added. A better solution is to have a single irq_chip instance which can deal with both edge and level triggered interrupts. It is also a good idea to switch the IRQ handler instead, as the edge IRQ handler allows for one edge IRQ event to be queued as the IRQ is actually masked only when that second IRQ is received, at which point the hardware can queue an additional IRQ event, making edge triggered interrupts a bit more reliable.

2009-02-14[ARM] 5390/1: AT91: Watchdog fixesAndrew Victor10-10/+10
The recently merged AT91SAM9 watchdog driver uses the AT91SAM9X_WATCHDOG config variable, whereas the original version of the driver (and the platform support code) used AT91SAM9_WATCHDOG. This causes the watchdog platform_device to never be registered, and therefore the driver not to be initialized. This patch: - updates the platform support code to use AT91SAM9X_WATCHDOG. - includes <linux/io.h> to fix compile error (same fix as was applied to at91rm9200_wdt.c) - fixes comment regarding watchdog clock-rates in at91rm9200.

2009-01-29ARM: OMAP: Mask interrupts when disabling interrupts, v2김규원1-0/+1
By Ingo Molnar, interrupts are not masked by default. (refer to 76d2160147f43f982dfe881404cfde9fd0a9da21) But if interrupts are not masked, the processor can wake up while in Suspend-to-RAM state by an external interrupt. For example, if an OMAP3 board is connected to Host PC by USB and entered to Suspend-to-RAM state, it wake up automatically by M_IRQ_92. The disable_irq() function can't disable the interrupt in H/W level, So I modified arch/arm/mach-omap2/irq.c Signed-off-by: Kim Kyuwon <chammoru@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-01-29ARM: OMAP: gptimer min_delta_ns correctedAaro Koskinen1-1/+2
When 32 kHz timer is used the min_delta_ns should be initialized so that it reflects the timer programming cost. A write to the timer device will be usually posted, but it takes roughly 3 cycles before it is effective. If the timer is reprogrammed before that, the CPU will stall until the previous write completes. This was pointed out by Richard Woodruff. Since the lower bound for min_delta_ns is 1000, the change is visible only with tick rates less than 3 MHz. Also note that the old value is incorrect for 32 kHz also due to a rounding error, and it can cause the timer queue to hang (due to clockevent code trying to program the timer with zero ticks).

2009-01-29ARM: OMAP: Fix McBSP spin_lock deadlockStanley.Miao4-223/+78
A spin_lock deadlock will occur when omap_mcbsp_request() is invoked. omap_mcbsp_request() \- clk_enable(mcbsp->clk) [takes and holds clockfw_lock] \- omap2_clk_enable() \- _omap2_clk_enable() \- omap_mcbsp_clk_enable() \- clk_enable(child clock) [tries for clockfw_lock again] mcbsp_clk is a virtual clock and it comprises several child clocks. when enable mcbsp_clk in omap_mcbsp_request(), the enable function of mcbsp_clk will enable its child clocks, then the deadlock occurs. The solution is to remove the virtual clock and enable these child clocks in omap_mcbsp_request() directly.

2009-01-28[ARM] 5366/1: fix shared memory coherency with VIVT L1 + L2 cachesNicolas Pitre1-1/+4
When there are multiple L1-aliasing userland mappings of the same physical page, we currently remap each of them uncached, to prevent VIVT cache aliasing issues. (E.g. writes to one of the mappings not being immediately visible via another mapping.) However, when we do this remapping, there could still be stale data in the L2 cache, and an uncached mapping might bypass L2 and go straight to RAM. This would cause reads from such mappings to see old data (until the dirty L2 line is eventually evicted.) This issue is solved by forcing a L2 cache flush whenever the shared page is made L1 uncacheable. Ideally, we would make L1 uncacheable and L2 cacheable as L2 is PIPT. But Feroceon does not support that combination, and the TEX=5 C=0 B=0 encoding for XSc3 doesn't appear to work in practice.

2009-01-19i.MX31: Image Processing Unit DMA and IRQ driversGuennadi Liakhovetski2-1/+190
i.MX3x SoCs contain an Image Processing Unit, consisting of a Control Module (CM), Display Interface (DI), Synchronous Display Controller (SDC), Asynchronous Display Controller (ADC), Image Converter (IC), Post-Filter (PF), Camera Sensor Interface (CSI), and an Image DMA Controller (IDMAC). CM contains, among other blocks, an Interrupt Generator (IG) and a Clock and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are supported over dmaengine and irq-chip APIs respectively. IDMAC is a specialised DMA controller, its DMA channels cannot be used for general-purpose operations, even though it might be possible to configure a memory-to-memory channel for memcpy operation. This driver will not work with generic dmaengine clients, clients, wishing to use it must use respective wrapper structures, they also must specify which channels they require, as channels are hard-wired to specific IPU functions.

2009-01-19[ARM] pxa: fix NAND and MMC clock initialization for pxa3xxMike Rapoport2-3/+3
After commit 8c3abc7d903df492a7394b0adae4349d9a381aaf ("[ARM] pxa: convert to clkdev and match clocks by struct device where possible") get_clk in pxa3xx_nand fails with -ENOENT. Apparently, clk_get in pxamci will also fail for MCI2 on PXA310. The 'clk_find' and therefore 'clk_get' require driver to supply both 'dev_id' and 'con_id' if they are not NULL in the 'strcut clk_lookup', but neither pxa3xx_nand nor pxamci supply 'con_id'. This patch sets 'con_id' to NULL in NAND clock and MCI2 clock registration. Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Eric Miao <eric.miao@marvell.com>

2009-01-15ARM: OMAP: Remove unused platform devices, v3Tony Lindgren10-419/+9
This patch removes old platform devices. Alsa should now be using the ASoC driver. For boards not yet using ASoC, please see sound/soc/omap/osk5912.c. Add dummy aic23_power_up and aic23_power_down functions for 770 to keep things compiling. Remove references to omap_gpio_switch, and unused h2_nand_dev_ready function. This patch is based on an earlier patch by Arun KS. Cc: Jarkko Nikula <jarkko.nikula@nokia.com> Signed-off-by: Arun KS <arunks@mistralsolutions.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
