2014-07-07HID: cp2112: fix gpio value in gpio_direction_outputAntonio Borneo1-2/+6
CP2112 does not offer an atomic method to set both gpio direction and value. Also it does not permit to set gpio value before putting gpio in output. In fact, accordingly to Silicon Labs AN495, Rev. 0.2, cpt. 4.4, the HID report to set gpio values "does not affect any pins that are not configured as outputs". This is confirmed on evaluation board CP2112-EK. With current driver, after execute: echo in > /sys/class/gpio/gpio248/direction echo low > /sys/class/gpio/gpio248/direction gpio output is still high. Only after a following echo low > /sys/class/gpio/gpio248/direction gpio output gets low. Fix driver by changing order of operations; first set direction then set value. The drawback of this new sequence is that we can have a pulse on gpio pin when direction is changed from input to output-low, but this cannot be avoided on current CP2112.

2014-06-25HID: sony: Always override the Sixaxis descriptorAntonio Ospite1-21/+10
Simplify the logic of overriding the Sixaxis HID descriptor, this will make it easier to amend the descriptor in future commits. The current code does this: if (original sixaxis via USB or BT) fixup only a part of the descriptor else if (sixaxis compatible controller) override the _whole_ descriptor but the end result is exactly the same, except for the trailing zero in the case of original BT controllers. So let's just regularize the process, and always override the HID descriptor. Always overriding the descriptor changes the current semantic a little bit, before this change the BT descriptor still had the trailing zero byte, while now it is exactly the same as the descriptor of the controller via USB, but that does not affect proper operation of the device. Note that overriding the whole descriptor for original devices is not strictly necessary for now, but it simplifies the code and in the future the report descriptor will be patched further and keys will be remapped, so it's handy to have only one place to patch.

2014-05-13HID: i2c-hid: hid report descriptor retrieval changesArchana Patni1-32/+13
Reading the partial HID Descriptor is causing a firmware lockup in some sensor hubs. Instead of a partial read, this patch implements the i2c hid fetch using a fixed descriptor size (30 bytes) followed by a verification of the BCDVersion (V01.00), and value stored in wHIDDescLength (30 Bytes) for V1.00 descriptors. As per i2c hid spec, this is the preferred model. From hid-over-i2c-protocol-spec-v1-0: There are a variety of ways a HOST may choose to retrieve the HID Descriptor from the DEVICE. The following is a preferred implementation but should not be considered the only implementation. A HOST may read the entire HID Descriptor in a single read by issuing a read for 30 Bytes to get the entire HID Descriptor from the DEVICE.However, the HOST is responsible for validating that 1. The BCDVersion is V01.00 (later revisions may have different descriptor lengths), and 2. The value stored in wHIDDescLength is 30 (Bytes) for V1.00 descriptors.
