| * mfd: twl-core: Add IRQ_DOMAIN dependencyGrant Likely2012-02-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | TWL4030 depends on IRQ_DOMAIN support, so this patch selects it in Kconfig. It used to be that CONFIG_IRQ_DOMAIN must only be selected by the architecture, but recent cleanups have fixed it so that it is safe to select from anywhere.

| * devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc)Grant Likely2012-02-273-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | Sparc has its own helpers for translating address ranges when the device tree is parsed at boot time, and it isn't able to use of_platform_populate(). However, there are some device drivers that want to use that function on other DT enabled platforms (ie. TWL4030). This patch adds an empty of_platform_populate() implementation that returns an error when CONFIG_OF_ADDRESS is not selected.

| * irq_domain: Centralize definition of irq_dispose_mapping()Grant Likely2012-02-274-22/+7Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several architectures define their own empty irq_dispose_mapping(). Since the irq_domain code is centralized now, there is little need to do so. This patch removes them and creates a new empty copy when !CONFIG_IRQ_DOMAIN is selected. The patch also means that IRQ_DOMAIN becomes selectable on all architectures. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: "David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes IRQ_DOMAIN usable on MIPS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | irq_domain_add_simple() was a stop-gap measure until complete irq_domain support was complete. This patch removes the irq_domain_add_simple() interface. This patch also drops the explicit irq_domain initialization performed by the mach-versatile code because the versatile interrupt controller already has irq_domain support built into it. This was a bug that was hanging around quietly for a while, but with the full irq_domain which actually verifies that irq_domain ranges are available it would cause the registration to fail and the system wouldn't boot. v4: Fixed number of irqs in mx5 gpio code v2: Updated to pass in host_data pointer on irq_domain allocation.

| * irq_domain: Add support for base irq and hwirq in legacy mappingsGrant Likely2012-02-165-38/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq) so that a controller driver can allocate a fixed range of irq_descs and use a simple calculation to translate back and forth between linux and hw irq numbers. This is needed to use an irq_domain with many of the ARM interrupt controller drivers that manage their own irq_desc allocations. Ultimately the goal is to migrate those drivers to use the linear revmap, but doing it this way allows each driver to be converted separately which makes the migration path easier. This patch generalizes the IRQ_DOMAIN_MAP_LEGACY method to use (first_irq-first_hwirq) as the offset between hwirq and linux irq number, and adds checks to make sure that the hwirq number does not exceed range assigned to the controller.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each revmap type has different arguments for setting up the revmap. This patch splits up the generator functions so that each revmap type can do its own setup and the user doesn't need to keep track of how each revmap type handles the arguments. This patch also adds a host_data argument to the generators. There are cases where the host_data pointer will be needed before the function returns. ie. the legacy map calls the .map callback for each irq before returning. v2: - Add void *host_data argument to irq_domain_add_*() functions - fixed failure to compile - Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: Olof Johansson <olof@lixom.net>

| * irq_domain/powerpc: eliminate irq_map; use irq_alloc_desc() insteadGrant Likely2012-02-142-198/+69Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch drops the powerpc-specific irq_map table and replaces it with directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating and freeing irq_desc structures. This patch is a preparation step for generalizing the powerpc-specific virq infrastructure to become irq_domains. As part of this change, the irq_big_lock is changed to a mutex from a raw spinlock. There is no longer any need to use a spin lock since the irq_desc allocation code is now responsible for the critical section of finding an unused range of irq numbers. The radix lookup table is also changed to store the irq_data pointer instead of the irq_map entry since the irq_map is removed. This should end up being functionally equivalent since only allocated irq_descs are ever added to the radix tree. v5: - Really don't ever allocate virq 0. The previous version could still do it if hint == 0 - Respect irq_virq_count setting for NOMAP. Some NOMAP domains cannot use virq values above irq_virq_count. - Use numa_node_id() when allocating irq_descs. Ideally the API should obtain that value from the caller, but that touches a lot of call sites so will be deferred to a follow-on patch. - Fix irq_find_mapping() to include irq numbers lower than NUM_ISA_INTERRUPTS. With the switch to irq_alloc_desc*(), the lowest possible allocated irq is now returned by arch_probe_nr_irqs(). v4: - Fix incorrect access to irq_data structure in debugfs code - Don't ever allocate virq 0 Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: Olof Johansson <olof@lixom.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch drops the powerpc-specific irq_host structures and uses the common irq_domain strucutres defined in linux/irqdomain.h. It also fixes all the users to use the new structure names. Renaming irq_host to irq_domain has been discussed for a long time, and this patch is a step in the process of generalizing the powerpc virq code to be usable by all architecture. An astute reader will notice that this patch actually removes the irq_host structure instead of renaming it. This is because the irq_domain structure already exists in include/linux/irqdomain.h and has the needed data members.

However, on Acer Aspire 6935, it seems that the speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it results in silence by some reason, although the codec itself allows the routing to DAC3/4. As a workaround, the connection list of each pin is reduced to be mapped to either only DAC1/2 or DAC3/4, so that the compatible assignment as in kernel 3.1 is achieved.

This confused the driver and it tries always overriding the input-source selection by assumption of the existing MUX for the secondary ADC, resulted in resetting the input-source at each time PM (including power-saving) occurs. The fix is simply to check the existence of MUX for secondary ADCs in the initialization code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new HP laptops turns off the mute LED with VREF50 or VREF80, but not in HIZ unlike the previous models. Since VREF50 (also 80) works with the previous models, let's use VREF50 for all. Signed-off-by: Takashi Iwai <tiwai@suse.de>

It'll pass the result of that check to handle_mid which will dequeue it and mark it with a status of MID_RESPONSE_MALFORMED if checkSMB returned an error. At that point, standard_receive3 will also return an error, which will make the demultiplex thread skip doing the callback for the mid. This is wrong -- if we were able to identify the request and the response is marked malformed, then we want the demultiplex thread to do the callback. Fix this by making standard_receive3 return 0 in this situation.

This is done by reverting to the original code, and avoiding the W duplication by moving its initialisation into the loop. As the underlying code is in fact the one that we have used for years, I'm pushing this now instead of postponing to the next cycle. * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: sha512 - Avoid stack bloat on i386 crypto: sha512 - Use binary and instead of modulus

As gcc has issues dealing with 64-bit ops on i386 this means that we end up using even more stack space (>1K). This patch solves the W reduction by moving LOAD_OP/BLEND_OP into the loop itself, thus avoiding the need to duplicate it. While the stack space still isn't great (>0.5K) it is at least in the same ball park as the amount of stack used for our C sha1 implementation. Note that this patch basically reverts to the original code so the diff looks bigger than it really is. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
