2018-05-09Input: add driver for Silead touchscreensRobert Dolca
This driver adds support for Silead touchscreens. It has been tested with GSL1680 and GSL3680 touch panels. It supports ACPI and device tree enumeration. Screen resolution, the maximum number of fingers supported and firmware name are configurable. Signed-off-by: Robert Dolca <robert.dolca@intel.com> Signed-off-by: Daniel Jansen <djaniboe@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Input: silead - remove some dead code buf[0] is an unsigned char. touch_nr is an int. The test for negative here doesn't make sense so I have removed it. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Input: silead - use devm_gpiod_get The silead code is using devm_foo for everything (and does not free any resources). Except that it is using gpiod_get instead of devm_gpiod_get (but is not freeing the gpio_desc), change this to use devm_gpiod_get so that the gpio will be properly released. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Input: silead_gsl1680 - document firmware-name, fix implementation The driver has supported touchscreen-fw-name to specify the firmware to load since it has been merged, but this was omitted from the dt-binding documentation. During review of adding touchscreen-fw-name to the binding documentation it was brought up that there is a standard property name called "firmware-name" for this, which should be used. Since there are no users of touchscreen-fw-name yet, this commit adds documentation of "firmware-name" to the dt-binding documentation and switches the driver over to use this. This commit also makes the driver add a "silead/" prefix to the firmware name from dt before calling request_firmware. That the firmware files are stored under /lib/firmware/silead under Linux is an implementation detail and does not belong in devicetree. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Input: silead_gsl1680 - use "silead/" prefix for firmware loading The silead touch-controller ICs use a different firmware per digitizer / tablet model. So there are going to be quite a few of then and they really should be under a separate subdir. This commit prefixes the default firmware names with "silead/" just like we are already doing for devicetree specified firmware names. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Input: silead - add OF device ID table The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. As pointed by Hans de Goede, there's no mssl1680 and this is just used in some ACPI systems to identify the gsl1680 chip. So isn't included in the OF device ID table since a DT should use the proper device name instead.

Return EPROBE_DEFER so the probe is retried later. To prevent an infinite probe loop when the firmware does not exist at all, the retries are capped to 10.

2018-04-18regulator: core: Add support to limit min_uV during system startupFinley Xiao
Now a regulator device can supply multiple consumers at the same time, if a consumer starts and set a low voltage, another consumer doesn't start in kernel but has been set a high frequency in bootloader will abort. This patch Adds support to limit min_uV during kernel startup to make sure the voltage can suit the needs of all consumers.

Pull f2fs updates from Jaegeuk Kim: "In this round, we've followed up to support some generic features such as cgroup, block reservation, linking fscrypt_ops, delivering write_hints, and some ioctls. And, we could fix some corner cases in terms of power-cut recovery and subtle deadlocks. Enhancements: - bitmap operations to handle NAT blocks - readahead to improve readdir speed - switch to use fscrypt_* - apply write hints for direct IO - add reserve_root=%u,resuid=%u,resgid=%u to reserve blocks for root/uid/gid - modify b_avail and b_free to consider root reserved blocks - support cgroup writeback - support FIEMAP_FLAG_XATTR for fibmap - add F2FS_IOC_PRECACHE_EXTENTS to pre-cache extents - add F2FS_IOC_{GET/SET}_PIN_FILE to pin LBAs for data blocks -

2018-03-05FROMLIST: MIPS: Add noexec=on|off kernel parameterMiodrag Dinic
Add a new kernel parameter to override the default behavior related to the decision whether to indicate stack as non-executable or executable (regardless of PT_GNU_STACK entry or CPU RIXI support) in function mips_elf_read_implies_exec(). Allowed values: noexec=on: force indicating non-exec stack & heap noexec=off: force indicating executable stack & heap If this parameter is omitted, kernel behavior remains the same as it was before this patch is applied. This functionality is convenient during debugging and is especially useful for Android development where indication of non-executable stack is required. NOTE: Using noexec=on on a system without CPU XI support is not recommended since there is no actual HW support that provide non-executable stack and heap. Use only for debugging purposes and not in a production environment.

2018-03-05UPSTREAM: MIPS: Add IEEE Std 754 conformance mode selectionMaciej W. Rozycki
Add an `ieee754=' kernel parameter to control IEEE Std 754 conformance mode. Use separate flags copied from the respective CPU feature flags, and adjusted according to the conformance mode selected, to make binaries requesting individual NaN encoding modes accepted or rejected as needed. Update the initial setting for FCSR and, in the full FPU emulation mode, its read-only mask accordingly. Accept the mode selection requested for legacy processors as well. As with the EF_MIPS_NAN2008 ELF file header flag adjust both ABS2008 and NAN2008 bits at the same time, to match the choice made for hardware currently implemented. Signed-off-by: Maciej W.
