2018-01-16gpiolib: Convert fwnode_get_named_gpiod() to configure GPIOAndy Shevchenko2-17/+3
Make fwnode_get_named_gpiod() consistent with the rest of gpiod_get() like API, i.e. configure GPIO pin immediately after request. Besides obvious clean up it will help to configure pins based on firmware provided resources.

2016-12-19Input: i8042 - Trust firmware a bit more when probing on X86Dmitry Torokhov1-3/+7
The error message "Can't read CTR while initializing i8042" appears on Cherry Trail-based devices at each boot time: i8042: PNP: No PS/2 controller found. Probing ports directly. i8042: Can't read CTR while initializing i8042 i8042: probe of i8042 failed with error -5 This happens because we historically do not trust firmware on X86 and, while noting that PNP does not show keyboard or mouse devices, we still charge ahead and try to probe the controller. Let's relax this a bit and if results of PNP probe agree with the results of platform initialization/quirks conclude that there is, in fact, no i8042. While at it, let's avoid using x86_platform.i8042_detect() and instead abort execution early if platform indicates that it can not possibly have i8042 (x86_platform.legacy.i8042 equals X86_LEGACY_I8042_PLATFORM_ABSENT).

msleep(1~20) may not do what the caller intends, and will often sleep longer. (~20 ms actual sleep for any value given in the 1~20ms range) This is not the desired behaviour for many cases like device resume time, device suspend time, device enable time, retry logic, etc. Thus, change msleep to usleep_range for precise wakeups.

We were assigning I2C bus controller instead of client as parent device. Besides being logically wrong, it messed up with devm handling of input device. As a result we were leaving input device and event node behind after rmmod-ing the driver, which lead to a kernel oops if one were to access the event node later. Let's remove the assignment and rely on devm_input_allocate_device() to set it up properly for us.
