This patch series has been tested against the following devices: - Sony Xperia 10 (SDM630 Ganges Kirin) - Sony Xperia 10 Plus (SDM636 Ganges Mermaid) Changes in v2: - Fixed sparse warnings from lkp kernel test robot Changes in v3 (as requested by Dmitry Torokhov): - Using shorthand u16/u32 (sorry for the overlook!) - Now using more input and touchscreen APIs - Fixed useless workqueue involvements - Removed useless locking - Switched reads and writes to use regmap - Moved header contents to nt36xxx.c - Fixed reset gpio handling - Other cleanups - P.S.: Thanks, Dmitry! Changes in v4: - Fixed regmap read length for CRC_ERR_FLAG final check - Fixed YAML binding, as requested by Krzysztof Kozlowski Changes in v5: - Replaced subsystem maintainer's name with .. mine, usage of additionalProperties to unevaluatedProperties and a typo fix for reset-gpios as per Rob Herring's review - Changed compatible string as per Krzysztof K. request - Renamed the novatek,nt36xxx.yaml file to just nt36xxx.yaml in order to now reflect the driver name instead of the DT compatible - Fixed blank line at EOF Changes in v6: - Removed include of_gpio.h, added mod_devicetable.h and gpio/consumer.h - Added kerneldoc to relevant functions/enum - Used traditional patterns for error checking where possible - Documented calls to usleep/msleep - Using be16_to_cpu / get_unaligned_be16 where possible - Added helper for CRC error check on retrieved buffer - Decreased indentation in the CRC reboot recovery function - Removed instances of error code sum - Dropped all likely/unlikely optimization as per request - Removed redundant reset_gpio checks - Dropped of_match_ptr and ifdefs for CONFIG_OF Changes in v7: - Fixed typo in nt36xxx.c Changes in v8: - Fixed typo reset-gpio -> reset-gpios in dt-bindings AngeloGioacchino Del Regno (3): dt-bindings: Add vendor prefix for Novatek Microelectronics Corp.
