* gpio: spear-spics: drop unused MODULE_ tags from non-modular codePaul Gortmaker2016-08-231-6/+1
| | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: drivers/gpio/Kconfig:config GPIO_SPEAR_SPICS drivers/gpio/Kconfig: bool "ST SPEAr13xx SPI Chip Select as GPIO support" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information is now contained at the top of the file in the comments. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

This driver is based on gpio-crystalcove.c. Changes in v7: - Fixed various coding style comments from Andy Shevchenko Changes in v6: - Removed unnecessary wcove_gpio_remove() - Used devm_gpiochip_remove() instead of gpiochip_remove() - Various coding style changes per Mika's comment Changes in v5: - Revisited the interrupt handler code to iterate until all pending interrupts are handled. This change is to avoid missing interrupt when we're inside the interrupt handler. - Used regmap_bulk_read() to read address adjacent registers. Changes in v4: - Converted CTLI_INTCNT_XX macros to less verbose ones INT_DETECT_XX. - Add comments about why there is no .pm for the driver. - Header files re-ordered. - Various coding style change to address Andy's comments. Changes in v3: - Fixed the year in copyright line(2015-->2016). - Removed DRV_NAME macro. - Added kernel-doc for regmap_irq_chip of the wcove_gpio structure. - Line length fix. Changes in v2: - Typo fix (Whsikey --> Whiskey). - Included linux/gpio/driver.h instead of linux/gpio.h - Implemented .set_single_ended(). - Added GPIO register description. - Replaced container_of() with gpiochip_get_data(). - Removed unnecessary "if (gpio > WCOVE_VGPIO_NUM" check. - Removed the device id table and added MODULE_ALIAS().

I have split Ville patch between zpos core and drivers version 5: - remove zpos range check and comeback to 0 to N-1 normalization algorithm version 4: - make sure that normalized zpos value is stay in the defined property range and warn user if not This patch adds support for generic plane's zpos property property with well-defined semantics: - added zpos properties to plane and plane state structures - added helpers for normalizing zpos properties of given set of planes - well defined semantics: planes are sorted by zpos values and then plane id value if zpos equals Normalized zpos values are calculated automatically when generic muttable zpos property has been initialized. Drivers can simply use plane_state->normalized_zpos in their atomic_check and/or plane_update callbacks without any additional calls to DRM core. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Compare to Marek's original patch zpos property is now specific to each plane and no more to the core. Normalize function take care of the range of per plane defined range before set normalized_zpos.

The container and fs parts both have acks from relevant experts. To use the new feature you have to add an F option to your binfmt_misc configuration" From the docs: "The usual behaviour of binfmt_misc is to spawn the binary lazily when the misc format file is invoked. However, this doesn't work very well in the face of mount namespaces and changeroots, so the F mode opens the binary as soon as the emulation is installed and uses the opened image to spawn the emulator, meaning it is always available once installed, regardless of how the environment changes" * tag 'binfmt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/binfmt_misc: binfmt_misc: add F option description to documentation binfmt_misc: add persistent opened binary handler for containers fs: add filp_clone_open API

If you pass in 'F' the binary that runs the emulation will be opened immediately and in future, will be cloned from the open file. The net effect is that the handler survives both changeroots and mount namespace changes, making it easy to work with foreign architecture containers without contaminating the container image with the emulator.

I've labelled this as an internal API because I can't see how it would be useful outside of the fs subsystem. The use case will be a persistent binfmt_misc handler.
