2018-12-21IB/umad: Use class_groups and let core create class fileParav Pandit
Use class->class_groups core kernel facility to create the abi version file instead of open coding.

2018-12-21IB/umad: Refactor code to use cdev_device_add()Parav Pandit
Refactor code to use cdev_device_add() and do other minor refactors while modifying these functions as below. 1. Instead of returning generic -1, return an actual error for ib_umad_init_port(). 2. Introduce and use ib_umad_init_port_dev() for sm and umad char devices. 3. Instead of kobj, use more light weight kref to refcount ib_umad_device. 4. Use modern cdev_device_add() single code cut down three steps of cdev_add(), device_create(). This further helps to move device sysfs files to class attributes in subsequent patch. 5. Remove few empty lines while refactoring these functions. 6. Use sizeof() instead of sizeof to avoid checkpatch warning. 7. Use struct_size() for calculation of ib_umad_port.

2018-12-21IB/umad: Avoid destroying device while it is accessedParav Pandit
ib_umad_reg_agent2() and ib_umad_reg_agent() access the device name in dev_notice(), while concurrently, ib_umad_kill_port() can destroy the device using device_destroy(). cpu-0 cpu-1 ----- ----- ib_umad_ioctl() [...] ib_umad_kill_port() device_destroy(dev) ib_umad_reg_agent() dev_notice(dev) Therefore, first mark ib_dev as NULL, to block any further access in file ops, unregister the mad agent and destroy the device at the end after mutex is unlocked. This ensures that device doesn't get destroyed, while it may get accessed.

2018-12-21IB/umad: Simplify and avoid dynamic allocation of classParav Pandit
Simplify code to have a static structure instance for umad class allocation. This will allow to have class attributes defined along with class registration in subsequent patch and allows more class methods definition similar to ib_core module.

2018-12-22treewide: surround Kconfig file paths with double quotesMasahiro Yamada
The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.

2018-12-21Input: add official Raspberry Pi's touchscreen driverNicolas Saenz Julienne
Add's support to Raspberry Pi's 7" Touch device. Instead of using a conventional bus all information is copied into a memory mapped area by RPi's firmware. Based on the driver found in RPi's kernel repository.

2018-12-21Input: elantech - disable elan-i2c for P52 and P72Benjamin Tissoires
The current implementation of elan_i2c is known to not support those 2 laptops. A proper fix is to tweak both elantech and elan_i2c to transmit the correct information from PS/2, which would make a bad candidate for stable. So to give us some time for fixing the root of the problem, disable elan_i2c for the devices we know are not behaving properly.

2018-12-21gpio: mvebu: only fail on missing clk if pwm is actually to be usedUwe Kleine-König
The gpio IP on Armada 370 at offset 0x18180 has neither a clk nor pwm registers. So there is no need for a clk as the pwm isn't used anyhow. So only check for the clk in the presence of the pwm registers. This fixes a failure to probe the gpio driver for the above mentioned gpio device.

2018-12-21gpio: max7301: fix driver for use with CONFIG_VMAP_STACKChristophe Leroy
spi_read() and spi_write() require DMA-safe memory. When CONFIG_VMAP_STACK is selected, those functions cannot be used with buffers on stack. This patch replaces calls to spi_read() and spi_write() by spi_write_then_read() which doesn't require DMA-safe buffers.

2018-12-21gpio: gpio-omap: Revert deferred wakeup quirk handling for regressionsTony Lindgren
Commit ec0daae685b2 ("gpio: omap: Add level wakeup handling for omap4 based SoCs") attempted to fix omap4 GPIO wakeup handling as it was blocking deeper SoC idle states. However this caused a regression for GPIOs during runtime having over second long latencies for Ethernet GPIO interrupt as reportedy by Russell King <rmk+kernel@armlinux.org.uk>. Let's fix this issue by doing a partial revert of the breaking commit. We still want to keep the quirk handling around as it is also used for OMAP_GPIO_QUIRK_IDLE_REMOVE_TRIGGER. The real fix for omap4 GPIO wakeup handling involves fixes for omap_set_gpio_trigger() and omap_gpio_unmask_irq() and will be posted separately. And we must keep the wakeup bit enabled during runtime because of module doing clock autogating with autoidle configured.
