2012-11-27Input: bu21013_ts - move GPIO init and exit functions into the driverLee Jones
These GPIO init and exit functions have no place in platform data, they should be part of the driver instead, Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2012-11-27Input: bu21013_ts - request regulator that actually existsLee Jones
Currently the BU21013 Touch Screen driver requests a regulator by the name of 'V-TOUCH', which doesn't exist anywhere in the kernel. The correct name, as referenced in platform regulator code is 'avdd'. Here, when we request a regulator, we use the correct name instead.

2012-11-25Input: imx_keypad - only set enabled columns to open-drainAndreas Pretzsch
In imx_keypad_inhibit(), all 8 columns were set to open-drain, in contrast to the rest of the driver, where only the enabled columns are modified/used. Contrary to the normal expectation, this also affects column I/Os not even mapped via IOMUX to the KPP hardware module but used as a GPIO. Therefore only init enabled columns to open-drain and leave all others with their default reset value of 0, i.e. totem-pole.

2012-11-08Input: introduce managed input devices (add devres support)Dmitry Torokhov
There is a demand from driver's writers to use managed devices framework for their drivers. Unfortunately up to this moment input devices did not provide support for managed devices and that lead to mixing two styles of resource management which usually introduced more bugs, such as manually unregistering input device but relying in devres to free interrupt handler which (unless device is properly shut off) can cause ISR to reference already freed memory. This change introduces devm_input_allocate_device() that will allocate managed instance of input device so that driver writers who prefer using devm_* framework do not have to mix 2 styles.
