Convert string compares of DT node names to use of_node_name_eq helper instead. For the root node on SUN DT, we need to retrieve the 'name' property as it is the rare case where the 'name' property and node name differ. With both changes, it removes direct access to the node name pointer. While at it, convert the open coded loop to use for_each_child_of_node().

Perform the register access only after the I2C client data are set, this is only done in preparation for the subsequent patch which uses the I2C client data in the register IO function. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - rework the touchscreen sample processingMarek Vasut
Get rid of the packed structures for representing data as that does not apply to other similar Ilitek touchscreens. Instead, implement a function which parses the data and reports touch events and coordinates. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-06Input: ili210x - convert to devm IRQMarek Vasut
Convert the driver to devm_request_irq(), drop the related unmanaged deregistration code and add ili210x_irq_teardown() to tear the IRQ down and cancel possible touchscreen pending work. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2019-02-06Input: ili210x - drop get_pendown_stateMarek Vasut
The .get_pendown_state callback is set only by the platform data code, which was just removed. Thus, get_pendown_state() always returns false, so drop that altogether. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2019-02-06Input: gpio-keys - add shutdown callbackFlorian Fainelli
On some platforms (e.g.: ARCH_BRCMSTB) it is possible to enter "poweroff" while leaving some wake-up sources enabled such as key presses in order to allow for the system to wake-up. Wire up a .shutdown() callback which calls into the existing gpio_keys_suspend() since the logic is essentially the same.

2019-02-04Input: sx8654 - convert #defined flags to BIT(x)Richard Leitner
