2015-07-23Input: usbtouchscreen - avoid unresponsive TSC-30 touch screenBernhard Bender1-0/+3
This patch fixes a problem in the usbtouchscreen driver for DMC TSC-30 touch screen. Due to a missing delay between the RESET and SET_RATE commands, the touch screen may become unresponsive during system startup or driver loading. According to the DMC documentation, a delay is needed after the RESET command to allow the chip to complete its internal initialization. As this delay is not guaranteed, we had a system where the touch screen occasionally did not send any touch data. There was no other indication of the problem. The patch fixes the problem by adding a 150ms delay between the RESET and SET_RATE commands.

Currently we are reporting the button state as inverted on all boards with an axp209 pmic, tested on a ba10-tvbox, bananapi, bananapro, cubietruck and utoo-p66 tablet. The axp209 datasheet clearly states that the power button must be connected between the PWRON key and ground. Which means that on a press we will get a falling edge (dbf) irq not a rising one, and likewise on release we will get a rising edge (dbr) irq, not a falling one. This commit swaps the check for the 2 irqs fixing the inverted reporting of the power button state.

Simplify drivers accordingly. Note that in the case of the drv260x driver error checking is more strict now because -ENOSYS is reported to the caller now.

2015-06-11Input: export LEDs as class devices in sysfsSamuel Thibault5-6/+226
This change creates a new input handler called "leds" that exports LEDs on input devices as standard LED class devices in sysfs and allows controlling their state via sysfs or via any of the standard LED triggers. This allows to re-purpose and reassign LDEs on the keyboards to represent states other than the standard keyboard states (CapsLock, NumLock, etc). The old API of controlling input LEDs by writing into /dev/input/eventX devices is still present and will take precedence over accessing via LEDs subsystem (i.e. it may override state set by a trigger). If input device is "grabbed" then requests coming through LED subsystem will be ignored.

Previously the elan_i2c touchpad driver would simply request the firmware "/lib/firmware/elan_i2c.bin", which does not work well if there are multiple such devices in the system. Let's append the "product ID" (by using the same function as the sysfs interface for consistency) to the filename. This results in filenames of the form "/lib/firmware/elan_i2c_72.0.bin", allowing you to support multiple elan_i2c touchpads on the same device by simply naming each device's FW with its corresponding product ID.

2015-06-02tty: remove platform_sysrq_reset_seqArnd Bergmann1-18/+1
The platform_sysrq_reset_seq code was intended as a way for an embedded platform to provide its own sysrq sequence at compile time. After over two years, nobody has started using it in an upstream kernel, and the platforms that were interested in it have moved on to devicetree, which can be used to configure the sequence without requiring kernel changes. The method is also incompatible with the way that most architectures build support for multiple platforms into a single kernel. Now the code is producing warnings when built with gcc-5.1: drivers/tty/sysrq.c: In function 'sysrq_init': drivers/tty/sysrq.c:959:33: warning: array subscript is above array bounds [-Warray-bounds] key = platform_sysrq_reset_seq[i]; We could fix this, but it seems unlikely that it will ever be used, so let's just remove the code instead.
