2013-08-05wandboard: modify mipi-csi to ipu mux setting3.0-wandboard-org-ts1John Weber
It appears that the default code copied from Freescale routes parallel CSI to IPU1, which is the IPU that we are using for MIPI-CSI. Change the route from parallel to MIPI

2013-08-01wandboard: fix mipi-csi exclusion and reorgJohn Weber
Fix a small bug when excluding MIPI from the build configuration. There was a '2' missing at the end of the CONFIG_IMX_HAVE_PLATFORM_IMX_MIPI_CSI2 var. Also, reorganized the code so that all of the IPU capture, MIPI, and sensor init is called using wand_init_mipi_csi(), which is a stub now when MIPI is deslected.

2013-07-28Set iMX6DQ/DL max speed back to 1GHzTapani
Commits 13c1310c and 7361e1f0 attempt to read undocumented memory bits (as of TRM released 2013-05-30) to determine CPU speed rating. This calculation appears to disable 1GHz mode for (some?) iMX6 Solo and DualLite CPUs sold by Freescale as 1GHz parts. This patch reverts the changes and hard-hacks the maximum speed to 1GHz for all iMX6 parts until more information is available. (cherry picked from commit 177c82740df1a817ccbe978ca687246e77a0718b)

2013-07-28brcmfmac: Handling the interrupt in ISR directly for non-OOBNi Wade
In case of inband interrupts, if we handle the interrupt in dpc thread, two level of thread switching takes place to process wifi interrupts. One in SDHCI driver and the other in Wifi driver. This may cause the system instability. Because the SDHCI calls sdio_irq_thread() to handle the irq, this thread locks mmc host and calls wifi handler. It expects WiFi handler to be quick and enables sdio interrupt from card at end. If wifi handler defers this work for a different thread, sdio_irq_thread() will be stuck on next wifi interrupt since mmc lock is not freed. Handling the interrupt in ISR directly will prevent thread context switching in wifi driver. It can fix the instability problems.

2013-07-28[RFC PATCH] i2c-imx.c: Add support for I2C bus fault recoveryDavid Jander
In the event that a I2C bus is disturbed, for instance by a slave missing a clock pulse, it is desirable to have a way to get the bus back working other than by power-cycling the whole system. This patch makes it possible to to have a special function in board support code issue an I2C reset, since the IMX peripheral is not capable of doing this, and it needs to be done by bit-banging the corresponding pins in GPIO mode. The reset function needs to check if the bus is hung by checking the state of SDA and issue a reset by pulsing SCL a few times as long as SDA is low.

2013-07-16ENGR00271359 Add Multi-touch supportErik Boto
The previous behavior of the driver did not work properly with Qt5 QtQuick multi touch-point gestures, due to how touch-points are reported when removing a touch-point. My interpretation of the available documentation [1] was that the driver should report all touch-points between SYN_REPORTs, but it is not explicitly stated so. I've found another mail-thread [2] where the creator of the protocol states: "The protocol defines a generic way of sending a variable amount of contacts. The contact count is obtained by counting the number of non-empty finger packets between SYN_REPORT events."-Henrik Rydberg I think this verifies my assumption that all touch-points should be reported between SYN_REPORTs, otherwise it can not be used to obtain the count.

2013-07-09ARM: 7670/1: fix the memset fixNicolas Pitre
Commit 455bd4c430b0 ("ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) optimizations") attempted to fix a compliance issue with the memset return value. However the memset itself became broken by that patch for misaligned pointers. This fixes the above by branching over the entry code from the misaligned fixup code to avoid reloading the original pointer. Also, because the function entry alignment is wrong in the Thumb mode compilation, that fixup code is moved to the end. While at it, the entry instructions are slightly reworked to help dual issue pipelines.

2013-07-09ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) ↵Ivan Djelic
optimizations Recent GCC versions (e.g. GCC-4.7.2) perform optimizations based on assumptions about the implementation of memset and similar functions. The current ARM optimized memset code does not return the value of its first argument, as is usually expected from standard implementations. For instance in the following function: void debug_mutex_lock_common(struct mutex *lock, struct mutex_waiter *waiter) { memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter)); waiter->magic = waiter; INIT_LIST_HEAD(&waiter->list); } compiled as: 800554d0 <debug_mutex_lock_common>: 800554d0: e92d4008 push {r3, lr} 800554d4: e1a00001 mov r0, r1 800554d8: e3a02010 mov r2, #16 ; 0x10 800554dc: e3a01011 mov r1, #17 ; 0x11 800554e0: eb04426e bl 80165ea0 <memset> 800554e4: e1a03000 mov r3, r0 800554e8: e583000c str r0, [r3, #12] 800554ec: e5830000 str r0, [r3] 800554f0: e5830004 str r0, [r3, #4] 800554f4: e8bd8008 pop {r3, pc} GCC assumes memset returns the value of pointer 'waiter' in register r0; causing register/memory corruptions. This patch fixes the return value of the assembly version of memset. It adds a 'mov' instruction and merges an additional load+store into existing load/store instructions. For ease of review, here is a breakdown of the patch into 4 simple steps: Step 1 ====== Perform the following substitutions: ip -> r8, then r0 -> ip, and insert 'mov ip, r0' as the first statement of the function. At this point, we have a memset() implementation returning the proper result, but corrupting r8 on some paths (the ones that were using ip). Step 2 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 1: save r8: - str lr, [sp, #-4]! + stmfd sp!, {r8, lr} and restore r8 on both exit paths: - ldmeqfd sp!, {pc} @ Now <64 bytes to go. + ldmeqfd sp!, {r8, pc} @ Now <64 bytes to go. (...) tst r2, #16 stmneia ip!, {r1, r3, r8, lr} - ldr lr, [sp], #4 + ldmfd sp!, {r8, lr} Step 3 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 0: save r8: - stmfd sp!, {r4-r7, lr} + stmfd sp!, {r4-r8, lr} and restore r8 on both exit paths: bgt 3b - ldmeqfd sp!, {r4-r7, pc} + ldmeqfd sp!, {r4-r8, pc} (...) tst r2, #16 stmneia ip!, {r4-r7} - ldmfd sp!, {r4-r7, lr} + ldmfd sp!, {r4-r8, lr} Step 4 ====== Rewrite register list "r4-r7, r8" as "r4-r8".

2013-07-05ENGR00269604 Fix the set clock-rate for audio & videoMahesh Mahadevan
There is single method to set clock-rate for both audio and video pll-s in i.MX6q clock system implementation. That's possible due to they have similar set of registers with a different bases. But there is also one common register: CCM_ANALOG_MISC2, which contains post-dividers. In current implementation, independently of whether audio or video clock is going to be set, the mask 0xc0000000 is applied to MISC2 register. This means, that if the audio clock rate is changed, the video clock post-dividers possibly will be corrupted. This patch fixes the issue described above.
