* dt: fix twl4030 for non-dt compile on x86Grant Likely2012-03-051-0/+1
| | | | | | | | twl4030 still doesn't build correctly for x86 allmodconfig. This fix solves the missing symbol errors. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Benoit Cousson <b-cousson@ti.com>
* 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 Likely2012-02-272-5/+4
| | | | | | | | | | | | 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: Remove 'new' irq_domain in favour of the ppc oneGrant Likely2012-02-161-12/+2
| | | | | | | | | | | | | | | | | | | | This patch removes the simplistic implementation of irq_domains and enables the powerpc infrastructure for all irq_domain users. The powerpc infrastructure includes support for complex mappings between Linux and hardware irq numbers, and can manage allocation of irq_descs. This patch also converts the few users of irq_domain_add()/irq_domain_del() to call irq_domain_add_legacy() instead. v3: Fix bug that set up too many irqs in translation range. v2: Fix removal of irq_alloc_descs() call in gic driver 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>
* mfd: twl-core.c: Fix the number of interrupts managed by twl4030Benoit Cousson2012-02-161-1/+1
| | | | | | | | | | TWL4030 does handle 3 different interrupts ranges: 8 for the core, 8 for the power events and 18 for the GPIOs.

* irq_domain: Replace irq_alloc_host() with revmap-specific initializersGrant Likely2012-02-161-5/+2
| | | | | | | | | | | | | | | | | | | | | | 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: Use common irq_domain structure instead of irq_hostGrant Likely2012-02-141-5/+5
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | When reading flags, bq27x00_read() argument is inverted and causes reads 2 of bytes for bq27200 and 1 byte for bq27500, while their register sizes are 1 and 2 bytes respectively. This causes bq27500 upper flag bits always to be returned as 0, causing full charge state to never be reported correctly, so fix it.

It reports "Not charging" while in fact there is >130mA current flowing to the battery according to current_now. This status report seems to be based on CHG bit in status register, but looking at the datasheet the description says "(Fast) charging allowed", which I guess means that the chip recommends charging and not that charging is actually going on? If you check the bit while battery is discharging and it's not full, the bit is also set.

Some of these changes will be reworked at the next merge window when the underlying reasons are sorted out. In the mean time, I think it's important to have this fixed for correctness. Also included in this set are fixes to various error messages in OMAP - including making them gramatically correct, fixing a few spelling errors, and more importantly, making them greppable by unwrapping them.

The lack of PMIC support in turn causes the loss of other functionality the kernel had. This dependency was added because the driver now registers its interrupts with the IRQ domain code, presumably to prevent a build error. The result is that OMAP3 oopses in the vp.c code (fixed by a previous commit) due to the lack of PMIC support. However, even with IRQ_DOMAIN enabled, the driver oopses: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = c0004000 [00000000] *pgd=00000000 Internal error: Oops: 5 [#1] SMP Modules linked in: CPU: 1 Not tainted (3.3.0-rc2+ #271) PC is at irq_domain_add+0x1c/0x134 LR is at twl_probe+0xd0/0x370 pc : [<c007bad0>] lr : [<c029baac>] psr: 00000113 sp : df843c48 ip : df843c68 fp : df843c64 r10: c02b93e4 r9 : 00000000 r8 : c029b9dc r7 : df9d8a00 r6 : c03bef90 r5 : 00000000 r4 : c03f5240 r3 : 00000000 r2 : c03f5240 r1 : 00000015 r0 : c03f5240 Flags: nzcv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c5387d Table: 8000404a DAC: 00000015 Process swapper/0 (pid: 1, stack limit = 0xdf8422f0) Stack: (0xdf843c48 to 0xdf844000) 3c40: 00000014 00000170 00000014 c03bef90 df843c9c df843c68 3c60: c029baac c007bac0 00000000 df9d8a20 00000001 c03cd238 c02b93e4 df9d8a20 3c80: df9d8a04 df9d8a00 c029b9dc df8cae08 df843cc4 df843ca0 c01eee70 c029b9e8 ...

Even through its initialization function fails, other code still calls its enable function, which fails to check whether it has this regulator before asking for it to be enabled. This fixes the oops, however a better fix would be to sort out the upper layers to prevent them calling into a module which failed to initialize.

It tries to tear down everything and tries to put a reference down in put_disk() which was never taken.

This occurs because the general practice in user space to query stats is to issue a ETHTOOL_GSSET cmd to learn the buffer size needed, allocate the buffer, then call ETHTOOL_GSTIRNGS and ETHTOOL_GSTATS. If the number of real_num_queues is changed or flow control attributes are changed after ETHTOOL_GSSET but before the ETHTOOL_GSTRINGS/ETHTOOL_GSTATS a user space buffer overrun occurs. To fix the overrun always return the max buffer size needed from get_sset_count() then return all strings and stats from get_strings()/get_ethtool_stats(). This _will_ change the output from the ioctl() call which could break applications and script parsing in theory. I believe these changes should not break existing tools because the only changes will be more {tx|rx}_queues and the {tx|rx}_pb_* stats will always be returned. Existing scripts already need to handle changing number of queues because this occurs today depending on system and current features. The {tx|rx}_pb_* stats are at the end of the output and should be handled by scripts today regardless. Finally get_ethtool_stats and get_strings are free-form outputs tools parsing these outputs should be defensive anyways. In the end these updates are better then having a tool segfault because of a buffer overrun.

Specifically it looks like that in 2.6.39 a change was made so that GRO would always have at least 16 frags available for coalescing, but the ixgbe RSC logic was not updated. As such the RSC feature would generate a frame larger than 64K and then overflow the value in the IP length field. To correct that I am now basing things on the PAGE_SIZE.

It appears that zd1211 firmware messes up duration_id field if it is not set to zero by driver. Sniffing traffic shows that zd1211 is transmitting frames with duration_id bits 14 and 15 set and other bits appearing random. Setting duration_id at driver to zero results zd1211 outputting sane duration_id. This means that firmware is setting correct values itself and expects duration_id to be zero in first place. Looking at vendor driver shows that only PSPoll frames have duration_id set by driver, for other frames duration_id left zero.

This is because the previous driver set the RFLR to 0x1000 (4096 bytes) and the skb allocate size is smaller than 4096 bytes. So, the controller accepted such a frame. The controller can discard a large frame by the RFLR setting. So, the patch modifies the value of RFLR to mtu + ETH_HLEN + VLAN_HLEN + ETH_FCS_LEN.
