* | OMAP: enable smc911x support for LDP platformRussell King2009-03-021-1/+1
|/ | | | | | | | | | | | | The following patch enables SMC911x support to work on the OMAP LDP board. Although the SMC911x driver will eventually be obsoleted, the smsc911x patches are rather invasive for the -rc kernels. Rather than risk destablising smsc911x, this simpler patch is preferred to allow the network interface to work.

* [ARM] omap: fix clock reparenting in omap2_clk_set_parent()Russell King2009-02-191-4/+4
| | | | | | | | | When changing the parent of a clock, it is necessary to keep the clock use counts balanced otherwise things the parent state will get corrupted.

* ARM: OMAP: Mask interrupts when disabling interrupts, v2김규원2009-01-291-0/+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>
* ARM: OMAP: gptimer min_delta_ns correctedAaro Koskinen2009-01-291-1/+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).

* ARM: OMAP: Fix McBSP spin_lock deadlockStanley.Miao2009-01-291-120/+25
| | | | | | | | | | | | | | | | | | | | | | | | 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.

Note that because gpio_direction_output() includes the initial value, this change isn't quite transparent. - For the call sites which defined an initial value either before or after setting the direction, that value was used. When that value was previously assigned afterwards, this could eliminate a brief output glitch ... and possibly change behavior. In a few cases (LCDs) several values were assigned together ... those were re-arranged to match the explicit sequence provided. - Some call sites didn't define such a value; so I chose an initial "off/reset" value that seemed to default to "off". In short, files touched by this patch might notice some small changes in startup behavior (with trivial fixes).

* | ARM: OMAP: switch to standard gpio get/set callsDavid Brownell2008-12-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces some legacy OMAP GPIO calls with the "new" (not really, any more!) calls that work on most platforms. The calls addressed by this patch are the simple ones to get and set values ... for code that's in mainline, including the implementations of those calls. Except for the declarations and definitions of those calls, all of these changes were performed by a simple SED script. Plus, a few "if() set() else set()" branches were merged by hand.

* | ARM: OMAP: Enable GPIO debounce clock only when debounce is enabled v3Jouni Hogander2008-12-101-18/+18
|/ | | | | | | | | | | | | | | | | | | This patch changes gpio "driver" to enable debounce clock for gpio-bank only when debounce is enabled for some gpio in that bank. Gpio functional clocks are also renamed in clock tree, gpioX_fck -> gpioX_dbck. This patch triggers problem with gpio wake-up and Omap3. Gpios in PER domain aren't capable to generate wake-up if PER domain is in sleep state. For this iopad wake-up should be used and needed pad configuration should be done. Enabling iopad wake-up for gpio pads is left for bootloader or omap mux configuration in kernel.

The sparseirq branch is just preliminary groundwork: no sparse IRQs are actually implemented by this tree anymore - just the new APIs are added while keeping the old way intact as well (the new APIs map 1:1 to irq_desc[]). The 'real' sparse IRQ support will then be a relatively small patch ontop of this - with a v2.6.29 merge target. * 'genirq-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (178 commits) genirq: improve include files intr_remapping: fix typo io_apic: make irq_mis_count available on 64-bit too genirq: fix name space collisions of nr_irqs in arch/* genirq: fix name space collision of nr_irqs in autoprobe.c genirq: use iterators for irq_desc loops proc: fixup irq iterator genirq: add reverse iterator for irq_desc x86: move ack_bad_irq() to irq.c x86: unify show_interrupts() and proc helpers x86: cleanup show_interrupts genirq: cleanup the sparseirq modifications genirq: remove artifacts from sparseirq removal genirq: revert dynarray genirq: remove irq_to_desc_alloc genirq: remove sparse irq code genirq: use inline function for irq_to_desc genirq: consolidate nr_irqs and for_each_irq_desc() x86: remove sparse irq from Kconfig genirq: define nr_irqs for architectures with GENERIC_HARDIRQS=n ...
