Hello, this is v3 of my "Input: goodix - add axis swapping and axis inversion support" patchset. The goodix touchscreen driver has gained device-tree support in kernel 4.1, but doesn't currently support the touchscreen-swapped-x-y, touchscreen-inverted-x and touchscreen-inverted-y properties. On systems which combine a portrait-mode display with a landscape-mode touchscreen, such as e.g. the MSI Primo 81 tablet, support for these features is necessary to have the touchscreen and the display use the same coordinate system. With support for axis inversion, the "rotated_screen" flag in the driver can also be removed, as "rotated_screen" is just a special case of x/y axis inversion. This patchset sits on top of the "[PATCH v9 0/9] Goodix touchscreen enhancements" series by Irina Tirdea: https://www.spinics.net/lists/linux-input/msg41501.html The axis swapping has successfully been tested on an (arm-based) MSI Primo 81 tablet; the x/y inversion resp. the rotated_screen functionality has successfully been tested on a WinBook TW100. @Bastien: You had acked patch No. 1 in v2 of the patchset. I have not transferred that ack to v3 of the same patch because I have have introduced some changes into that patch (based on Irina's review comments, cf. the changelog below) after your ack. I would apprechiate very much if you could take a look and tell me whether your ack extends to v3 as well. Regards, Karsten Changelog: v1: * Initial version (based von v6 of Irina Tirdea's "Goodix touchscreen enhancements" series). Reviewed-by: Bastien Nocera <hadess@xxxxxxxxxx> v2: * Rebase against v8 of Irina Tirdea's "Goodix touchscreen enhancements" series. * Fix a typo in the commit message. * Add an update for the goodix dt bindings documentation (patch No. 3). * Reviews/Tests: Patch 1+2: Tested-by: Bastien Nocera <hadess@xxxxxxxxxx> Acked-by: Bastien Nocera <hadess@xxxxxxxxxx> Patch 2+3: Reviewed-by: Irina Tirdea <irina.tirdea@xxxxxxxxx> v3: * Rebase against v9 of Irina Tirdea's "Goodix touchscreen enhancements" series. * Address the review comments for patch No. 1 by Irina Tirdea (https://www.spinics.net/lists/linux-input/msg41536.html): - Move reading the dt properties from goodix_ts_probe to goodix_configure_dev to make them work properly in all configurations (with and without gpio declarations). - Use the new unified device properties API (device_property_*) instead of the classic DT API (of_property_*). This provides support for ACPI 5.1 DSD properties as well as for device-tree properties.
