Hi, This is PATCHv3 of the EXC80Hxx support patchset.
Changes since [PATCHv2]: - add #include <linux/size.h> for SZ_4K and SZ_16K (kbuild test bot) - fw_version_show must be ssize_t (kbuild test bot) - rename YAML binding file to include eeti, prefix (Enric) - noise from gpio-reset patch (Enric) - add comment for the retry loop (Enric, Martin) - document sysfs entries (Enric) Changes since [PATCHv1]: - prepend new patch converting binding document to YAML - prepend new patch switching to I2C probe_new - append new patch adding reset-gpio support - use explicit compatible values for the touchscreen chips instead of a wildcast. Since the documentation, that I have is very vague let's use different values for exc80h60 and exc80h84. This avoids wildcard DT entries and means we are prepared when noticing differences between the chips. - add accidently removed terminator entry in exc3000_id - use device structure with max_xy and name (suggested by Martin) - use SZ_4K, SZ_16K defines (suggested by Dmitry) - harden event check, so that MT1 and MT2 based chips only allow their own event type. - write more detailed commit description in the fw_version/model sysfs patch to explain why the values are not cached and why the simpler read(); sleep(); write() approach has not been used - use DEVICE_ATTR_RO() in fw_version/model patch to improve readability - fw_version/model: replace memcpy + null termination with strlcpy - fw_version/model: increase buffer size for weird firmware versions - fw_version/model: use sizeof() instead of hardcoded buffer sizes - simplify exc3000_query_interrupt() by moving the complete() call to the exc3000_interrupt(). I think I only ignored one review feedback, that the fw_version and model sysfs nodes are attached to the input device instead of the i2c device. This was done to avoid being racy: http://kroah.com/log/blog/2013/06/26/how-to-create-a-sysfs-file-correctly/ Thanks in advance for looking at the patches, -- Sebastian [PATCHv2] https://lore.kernel.org/linux-input/20200519182447.73405-1-sebastian.reic...@collabora.com/ [PATCHv1] https://lore.kernel.org/linux-input/20191107181010.17211-1-sebastian.reic...@collabora.com/ Sebastian Reichel (5): dt-bindings: touchscreen: Convert EETI EXC3000 touchscreen to json-schema Input: EXC3000: switch to i2c's probe_new API Input: EXC3000: add EXC80H60 and EXC80H84 support Input: EXC3000: Add support to query model and fw_version Input: EXC3000: Add reset gpio support .../ABI/testing/sysfs-driver-input-exc3000 | 15 ++ .../input/touchscreen/eeti,exc3000.yaml | 58 +++++ .../bindings/input/touchscreen/exc3000.txt | 26 -- drivers/input/touchscreen/exc3000.c | 245 ++++++++++++++++-- 4 files changed, 301 insertions(+), 43 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-driver-input-exc3000 create mode 100644 Documentation/devicetree/bindings/input/touchscreen/eeti,exc3000.yaml delete mode 100644 Documentation/devicetree/bindings/input/touchscreen/exc3000.txt -- 2.26.2
