Input: cyttsp5 - fix sensing configuration data structure

2023-04-14T06:44:12Z

Prior to this patch, the sensing configuration data was not parsed correctly, breaking detection of max_tch. The vendor driver includes this field. This change informs the driver about the correct maximum number of simultaneous touch inputs. Tested on a Pine64 PineNote with a modified touch screen controller firmware.

Input: goodix - add Lenovo Yoga Book X90F to nine_bytes_report DMI table

2023-03-17T10:24:40Z

The Android Lenovo Yoga Book X90F / X90L uses the same goodix touchscreen with 9 bytes touch reports for its touch keyboard as the already supported Windows Lenovo Yoga Book X91F/L, add a DMI match for this to the nine_bytes_report DMI table. When the quirk for the X91F/L was initially added it was written to also apply to the X90F/L but this does not work because the Android version of the Yoga Book uses completely different DMI strings. Also adjust the X91F/L quirk to reflect that it only applies to the X91F/L models.

Input: cyttsp5 - fix bitmask for touch buttons

2023-02-04T00:59:15Z

Prior to this patch, the bitmask ends up being 0x3, as opposed to 0x1 which likely was the intention. The erroneous bit results in the driver reporting 2 different button activations in designs with 2 or more buttons. To detect which button has been pressed, cyttsp5_btn_attention() uses a for loop to iterate through the input buffer, while shifting and applying a bitmask to determine the state for each button. Unfortunately, when the bitmask is 0x3 and there are multiple buttons, this procedure falls apart. Consider a design with 3 buttons. Pressing the third button will result in a call to cyttsp5_btn_attention() with the input buffer containing 0x4 (binary 0100). In the first iteration of the for loop cur_btn_state will be: (0x4 >> 0 * 1) & 0x3 = 0x4 & 0x3 = 0x0 This is correct. However, in the next iteration this happens: (0x4 >> 1 * 1) & 0x3 = 0x2 & 0x3 = 0x2 Which means that a key event for key 1 is generated, even though it's not really active. In the third iteration, the loop detects the button that was actually pressed: (0x4 >> 2 * 1) & 0x3 = 0x1 & 0x3 = 0x1 This key event is the only one that should have been detected, but it is accompanied by the preceding key. Ensuring the applied mask is 0x1 solves this problem.

mfd: remove ucb1400 support

2023-02-01T16:23:38Z

The ucb1400 MFD driver and its gpio and touchscreen child drivers were only used on a few PXA machines that were unused for a while and are now removed. Removing these leaves the AC97 support as ALSA specific, no other drivers are now connected through this interface.
