Floating pins towards the camera input level-shifter cause it to consume at least 100mW of power even in idle. This patch fixes this by configuring pull-downs on all multiplexed camera input pins.

2016-09-29compiler-gcc: disable -ftracer for __noclone functionsPaolo Bonzini
commit 95272c29378ee7dc15f43fa2758cb28a5913a06d upstream. -ftracer can duplicate asm blocks causing compilation to fail in noclone functions. For example, KVM declares a global variable in an asm like asm("2: ... \n .pushsection data \n .global vmx_return \n vmx_return: .long 2b"); and -ftracer causes a double declaration.

2016-09-29compiler-gcc.h: Add gcc-recommended GCC_VERSION macroDaniel Santos
Throughout compiler*.h, many version checks are made. These can be simplified by using the macro that gcc's documentation recommends. However, my primary reason for adding this is that I need bug-check macros that are enabled at certain gcc versions and it's cleaner to use this macro than the tradition method: #if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ => 2) If you add patch level, it gets this ugly: #if __GNUC__ > 4 || (__GNUC__ == 4 && (__GNUC_MINOR__ > 2 || \ __GNUC_MINOR__ == 2 __GNUC_PATCHLEVEL__ >= 1)) As opposed to: #if GCC_VERSION >= 40201 While having separate headers for gcc 3 & 4 eliminates some of this verbosity, they can still be cleaned up by this.

2016-09-29ftrace: Make all inline tags also include notraceSteven Rostedt
Commit 5963e317b1e9d2a ("ftrace/x86: Do not change stacks in DEBUG when calling lockdep") prevented lockdep calls from the int3 breakpoint handler from reseting the stack if a function that was called was in the process of being converted for tracing and had a breakpoint on it. The idea is, before calling the lockdep code, do a load_idt() to the special IDT that kept the breakpoint stack from reseting. This worked well as a quick fix for this kernel release, until a certain config caused a lockup in the function tracer start up tests. Investigating it, I found that the load_idt that was used to prevent the int3 from changing stacks was itself being traced! Even though the config had CONFIG_OPTIMIZE_INLINING disabled, and all 'inline' tags were set to always inline, there were still cases that it did not inline! This was caused by CONFIG_PARAVIRT_GUEST, where it would add a pointer to the native_load_idt() which made that function to be traced. Commit 45959ee7aa645815a ("ftrace: Do not function trace inlined functions") only touched the 'inline' tags when CONFIG_OPMITIZE_INLINING was enabled. PARAVIRT_GUEST shows that this was not enough and we need to also mark always_inline with notrace as well.

2016-09-29ftrace: Do not function trace inlined functionsSteven Rostedt
When gcc inlines a function, it does not mark it with the mcount prologue, which in turn means that inlined functions are not traced by the function tracer. But if CONFIG_OPTIMIZE_INLINING is set, then gcc is allowed not to inline a function that is marked inline. Depending on the options and the compiler, a function may or may not be traced by the function tracer, depending on whether gcc decides to inline a function or not. This has caused several problems in the pass becaues gcc is not always consistent with what it decides to inline between different gcc versions. Some places should not be traced (like paravirt native_* functions) and these are mostly marked as inline. When gcc decides not to inline the function, and if that function should not be traced, then the ftrace function tracer will suddenly break when it use to work fine. This becomes even harder to debug when different versions of gcc will not inline that function, making the same kernel and config work for some gcc versions and not work for others. By making all functions marked inline to not be traced will remove the ambiguity that gcc adds when it comes to tracing functions marked inline. All gcc versions will be consistent with what functions are traced and having volatile working code will be removed. Note, only the inline macro when CONFIG_OPTIMIZE_INLINING is set needs to have notrace added, as the attribute __always_inline will force the function to be inlined and then not traced.

2016-06-22mmc: sdhci: handle command timeout after transfer complete interruptNicolas Serafini
On a tegra3 platform with Hynix eMMC we can observe that sometimes we receive a command timeout after a transfer complete interrupt on a multiple block read request. Here is the output using MMC_DEBUG and ftrace. When it works: tegra_sdhci_set_clock: tegra_sdhci_set_clock mmc0 0 enabled=1 tegra_sdhci_set_clock: tegra_sdhci_set_clock mmc0 52000000 enabled=0 __mmc_start_req: mmc0: starting CMD18 arg 00a73044 flags 000000b5 __mmc_start_req: mmc0: blksz 512 blocks 2 flags 00000200 tsac 150 ms nsac 1000 __mmc_start_req: mmc0: CMD12 arg 00000000 flags 0000049d sdhci_irq: sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00000001 sdhci_finish_command: sdhci_finish_command:1075 sdhci_irq: sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00000002 sdhci_tasklet_finish: sdhci_tasklet_finish:2064 When we have the error: tegra_sdhci_set_clock: tegra_sdhci_set_clock mmc0 0 enabled=1 tegra_sdhci_set_clock: tegra_sdhci_set_clock mmc0 52000000 enabled=0 __mmc_start_req: mmc0: starting CMD18 arg 00a63d12 flags 000000b5 __mmc_start_req: mmc0: blksz 512 blocks 2 flags 00000200 tsac 150 ms nsac 1000 __mmc_start_req: mmc0: CMD12 arg 00000000 flags 0000049d sdhci_irq: sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00000001 sdhci_finish_command: sdhci_finish_command:1075 sdhci_irq: sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00018000 ------NOW THE REQUEST BLOCK UNTIL TIMEOUT------ We can see that when it works the multiple read blocks command stopped by the CMD12 receive two interrupts. The first is the Transfer complete interrupt (SDHCI_INT_RESPONSE) and just after the Block Gap Event interrupt (SDHCI_INT_DATA_END). In this case the command is finished and the data is finished too. In the bad case instead of receiving SDHCI_INT_DATA_END we receive a command timeout error (SDHCI_INT_TIMEOUT) but command was already finished by the SDHCI_INT_RESPONSE so not more command is waiting and the driver wait until the timeout timer end because this case is not managed.

2016-03-22ARM: 8429/1: disable GCC SRA optimizationArd Biesheuvel
While working on the 32-bit ARM port of UEFI, I noticed a strange corruption in the kernel log. The following snprintf() statement (in drivers/firmware/efi/efi.c:efi_md_typeattr_format()) snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]", was producing the following output in the log: | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | | | | |UC] |RUN| | | | | | | |UC] As it turns out, this is caused by incorrect code being emitted for the string() function in lib/vsprintf.c. The following code if (!(spec.flags & LEFT)) { while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } } for (i = 0; i < len; ++i) { if (buf < end) *buf = *s; ++buf; ++s; } while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } when called with len == 0, triggers an issue in the GCC SRA optimization pass (Scalar Replacement of Aggregates), which handles promotion of signed struct members incorrectly. This is a known but as yet unresolved issue. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular case, it is causing the second while loop to be executed erroneously a single time, causing the additional space characters to be printed. So disable the optimization by passing -fno-ipa-sra.

Please note that those pins are usually used for the 8-bit MMC/SD slot aka Apalis MMC1 and the SDHCI controller/driver unfortunately changes the output driver behaviour in a way preventing any regular GPIO use.

defined(@array) is deprecated in Perl and gives off a warning. Restructure the code to remove that warning. [ hpa: it would be interesting to revert to the timeconst.bc script. It appears that the failures reported by akpm during testing of that script was due to a known broken version of make, not a problem with bc. The Makefile rules could probably be restructured to avoid the make bug, or it is probably old enough that it doesn't matter. ] Reported-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: H.

2015-11-02input: touchscreen: fusion: implement multitouch with slot handlingStefan Agner
According to multi-touch-protocol.txt the kernel knows two type of devices: - Type A: devices which provide anonymous contacts - Type B: devices which are capable of tracking individual contacts The Fusion touch screen is a Type B device: The Touch ID field allows to differentiate between 2 different fingers. This updates the driver to properly allocate a slot for each identified contact and use the helper functions available from the input core system.

Use level triggered interrupt which makes sure that even we miss a rising edge (due to latencies in the kernel), the interrupt still will be handled later, and doesn't freeze the input device. (cherry picked from commit ef25b8a9f9c0ca7cc0f0f955d89d112c3e19f75b)

Turns out the Tegra 3 USB PHY driver had some hard coded dependency on the Tegra OTG driver but we usually just use our own OTG driver purely relying on a cable detect GPIO to determine USB device vs. host role.

2015-10-14mmc: core: Disable HPI for certain Hynix eMMC cardsMarcel Ziswiler
Certain Hynix eMMC 4.41 cards might get broken when HPI feature is used and hence this patch disables the HPI feature for such buggy cards. As some of the other features like BKOPs/Cache/Sanitize are dependent on HPI feature, those features would also get disabled if HPI is disabled.

2015-10-11mmc: sdhci: handle busy-end interrupt during commandChanho Min
It is fully legal for a controller to start handling busy-end interrupt before it has signaled that the command has completed. So make sure we do things in the proper order, Or it results that command interrupt is ignored so it can cause unexpected operations. This is founded at some toshiba emmc with the bellow warning. "mmc0: Got command interrupt 0x00000001 even though no command operation was in progress." This issue has been also reported by Youssef TRIKI: It is not specific to Toshiba devices, and happens with eMMC devices as well as SD card which support Auto-CMD12 rather than CMD23. Also, similar patch is submitted by: Gwendal Grignou <gwendal@chromium.org> Changes since v1: Fixed conflict with the next of git.linaro.org/people/ulf.hansson/mmc.git and Tested if issue is fixed again.

When we wait for busy after sending a command, if there is a timeout, we got SDHCI_INT_DATA_TIMEOUT flags.

2015-10-11mmc: sdhci: clean up sdio interrupt enable handlingRussell King
We don't need to change the SDHCI_SDIO_IRQ_ENABLED flag when we're merely receiving an interrupt - IRQ handling thread in the MMC core will either re-enable or disable the interrupt via the enable_sdio_irq callback, which will update this status appropriately.
