gpio: sx150x: move platform data into driver

2016-04-14T12:03:25Z

The sx150x has some platform data definition in but this file is only included from the driver in the whole kernel so move its contents into the driver. Cc: Wei Chen Cc: Peter Rosin Acked-by: Wolfram Sang Signed-off-by: Linus Walleij

gpio: sx150x: correct and refine reset-on-probe behavior

2010-09-10T01:57:24Z

Replace the arbitrary software-reset call from the device-probe method, because: - It is defective. To work correctly, it should be two byte writes, not a single word write. As it stands, it does nothing. - Some devices with sx150x expanders installed have their NRESET pins ganged on the same line, so resetting one causes the others to reset - not a nice thing to do arbitrarily! - The probe, usually taking place at boot, implies a recent hard-reset, so a software reset at this point is just a waste of energy anyway. Therefore, make it optional, defaulting to off, as this will match the common case of probing at powerup and also matches the current broken no-op behavior.
