Input: iqs7222 - add support for IQS7222A v1.13+

2022-12-31T12:33:08+00:00

[ Upstream commit 8d4c313c03f104c69e25ab03058d8955be9dc387 ] IQS7222A revisions 1.13 and later widen the gesture multiplier from x4 ms to x16 ms. Add a means to scale the gesture timings specified in the device tree based on the revision of the device.

Input: iqs7222 - report malformed properties

2022-12-31T12:33:08+00:00

[ Upstream commit 404f3b48e65f058d94429e4a1ec16a1f82ff3b2f ] Nonzero return values of several calls to fwnode_property_read_u32() are silently ignored, leaving no way to know the properties were not applied in the event of an error. Solve this problem by evaluating fwnode_property_read_u32()'s return value, and reporting an error for any nonzero return value not equal to -EINVAL which indicates the property was absent altogether.

Input: iqs7222 - drop unused device node references

2022-12-31T12:33:08+00:00

[ Upstream commit bbd16b0d839978e8c8bec2b9a162373f64fc2fbb ] Each call to device/fwnode_get_named_child_node() must be matched with a call to fwnode_handle_put() once the corresponding node is no longer in use. This ensures a reference count remains balanced in the case of dynamic device tree support. Currently, the driver never calls fwnode_handle_put(). Solve this problem by moving the node handling from iqs7222_parse_props() to the new iqs7222_parse_reg_grp(), leaving the former to do nothing but parse properties. The latter then manages the reference count in a single location and consistent fashion. This change drastically simplifies iqs7222_parse_all(), which can then call iqs7222_parse_reg_grp() on every register group without having to treat each register group differently. For nested event nodes, common parsing code has been factored out to the new iqs7222_parse_event() so as to allow the event node to be dropped from as few locations as possible. As part of this refactor, the 'linux,code' property has been made optional. This enables applications that define an event with the sole purpose of enabling a GPIO.

Input: elants_i2c - properly handle the reset GPIO when power is off

2022-12-31T12:32:12+00:00

[ Upstream commit a85fbd6498441694475716a4d5c65f9d3e073faf ] As can be seen in elants_i2c_power_off(), we want the reset GPIO asserted when power is off. The reset GPIO is active low so we need the reset line logic low when power is off to avoid leakage. We have a problem, though, at probe time. At probe time we haven't powered the regulators on yet but we have: devm_gpiod_get(&client->dev, "reset", GPIOD_OUT_LOW); While that _looks_ right, it turns out that it's not. The GPIOD_OUT_LOW doesn't mean to init the GPIO to low. It means init the GPIO to "not asserted". Since this is an active low GPIO that inits it to be high. Let's fix this to properly init the GPIO. Now after both probe and power off the state of the GPIO is consistent (it's "asserted" or level low). Once we fix this, we can see that at power on time we no longer to assert the reset GPIO as the first thing. The reset GPIO is _always_ asserted before powering on. Let's fix powering on to account for this.
