2014-07-10ENGR00318392 ARM:imx6x: Save/restore SCU and some CP15 registers across ↵Ranjani Vaidyanathan
suspend/resume This patch ensures that the SCU and certain A9 CP15 registers state are maintained across a suspend/resume cycle: 1. Need to ensure that SCU standby bit is set again after suspend/resume cycle, else the system will never WAIT mode after a suspend/resume cycle. This bit should be enabled on all SMP systems immaterial of whether CPUIDLE is enabled or not. 2. Several A9 errata workarounds involve setting bits in the ARM diagnostic register. Save/restore this register across a suspend/resume cycle. 3. Save and restore the A9 power control register also.

2014-07-10input: touchscreen: fusion: add device tree integrationMax Krummenacher
Add device tree integration and add the device to the dtb. i2c device, interrupt and reset GPIO can be specified in the dts as follows: Note that additionally you may have to set the pinmuxing for the pins to be GPIO. &i2c1 { status = "okay"; pcap@10 { /* TouchRevolution Fusion 7 and 10 multi-touch controller */ compatible = "touchrevolution,fusion-f0710a"; reg = <0x10>; gpios = <&gpio6 10 0 /* MXM-11, Pen down interrupt */ &gpio6 9 0 /* MXM-13, Reset interrupt */ >; };

2014-07-08input: touchscreen: fusion: fix error handlingStefan Agner
Fix chip reset by sleeping long enought after reset. Do proper error handling (free GPIO on failure). Use dev_* for message logging to get similar messages for all fusion driver related errors and warnings. (cherry picked from commit 63b293000723e61a880470f093fbe82e86ebd81b)

2014-07-08input: touchscreen: added platform data for Fusion touchscreenStefan Agner
Added platform data struct to define interrupt and reset GPIO. This allows to initialize the touchscreen controller inside the driver rather then in each platform and use the driver as a module. (cherry picked from commit cb82730b70f31af3b43041ac4e47de69c18016c9)
2014-07-08input: touchscreen: fix race condition in Fusion driverStefan Agner
When the next interrupt request apeares between the confirmation of the previous (a write via I2C, fusion_F0710A_write_complete) and the reenable of the GPIO interrupt, the driver hangs and no more touch inputs are reported. This patch moves the confirmation after the reenabling of the GPIO interrupt. (cherry picked from commit e95019a4f20b8cdfbe03658e4f73b69cdcf97540)

2014-06-25mmc: use SD/MMC host ID for block device name IDStefan Agner
From: Stefan Agner <stefan@agner.ch> By using the SD/MMC host device ID as a starting point for block device numbering, one can reliably predict the first block device name (at least for the first controller). This is especially useful for SoCs with multiple SD/MMC host controller, where the controller with index 0 is connected to a eMMC device. Usually the first controller gets the first block device name ID, however this is not guaranteed. Also if the first controller is aliased as second controller and visa-versa (using device tree aliases), the block device name ID assignation is not ordered by the SD/MMC host device ID (since mmc_rescan is called in order of the memory mapped pheripherial addresses).

2014-06-25mmc: use SD/MMC host ID for block device name IDStefan Agner
From: Stefan Agner <stefan@agner.ch> To get the SD/MMC host device ID, read the alias from the device tree. This is useful in case a SoC has multipe SD/MMC host controllers while the second controller should logically be the first device (e.g. if the second controller is connected to an internal eMMC). Combined with block device numbering using MMC/SD host device ID, this results in predictable name assignment of the internal eMMC block device. Signed-off-by: Stefan Agner <stefan@agner.ch>

2014-04-24mm: ensure get_unmapped_area() returns higher address than mmap_min_addrAkira Takeuchi
commit 2afc745f3e3079ab16c826be4860da2529054dd2 upstream. This patch fixes the problem that get_unmapped_area() can return illegal address and result in failing mmap(2) etc. In case that the address higher than PAGE_SIZE is set to /proc/sys/vm/mmap_min_addr, the address lower than mmap_min_addr can be returned by get_unmapped_area(), even if you do not pass any virtual address hint (i.e. the second argument). This is because the current get_unmapped_area() code does not take into account mmap_min_addr. This leads to two actual problems as follows: 1. mmap(2) can fail with EPERM on the process without CAP_SYS_RAWIO, although any illegal parameter is not passed. 2. The bottom-up search path after the top-down search might not work in arch_get_unmapped_area_topdown(). Note: The first and third chunk of my patch, which changes "len" check, are for more precise check using mmap_min_addr, and not for solving the above problem.
