Commit 7677ed11 ("dt-bindings: mfd: qcom,tcsr: Convert to dtschema") converted bindings to DT schema literally - including the qcom,tcsr-ipq6018 expecting syscon and simple-mfd. Such configuration is not used in DTS and there is no actual need of it. The TCSR block is purely configuration block and should not have children. Any child device should be simply moved outside of TCSR syscon block. Signed-off-by:

Commit 5621d3977e29 ("dt-bindings: mfd: Add missing (unevaluated| additional)Properties on child nodes") exposed a flaw in the original binding, where "merged" versions of some regulators were missing, leading to warnings on the HiFive Unmatched Devicetree.

This patch switches the driver away from legacy gpio/of_gpio API to gpiod API, and removes use of of_get_named_gpio_flags() which I want to make private to gpiolib. We also need to patch relevant DTS files, as the original code relied on the fact that of_get_named_gpio_flags() would fetch any data encoded in GPIO flags, even if it does not reflect valid flags for a GPIO.

Instead of passing GPIO numbers pertaining to ourselves through platform data, just request GPIO descriptors from our own GPIO chips and use them, and cut down on the unnecessary complexity.

Michal Oleszczyk authored
When we consider MFD which implements hotplug (e.g. USB hotplug driver based on product and vendor IDs) functionality it turns out that its sub-devices are correctly matched with corresponding device tree nodes only at the first time. When physical device reboots or is replugged (and MFD driver is disconnected and probed back again) all sub-devices fails in mfd_add_device() with error 'Failed to locate of_node'. The reason of that behavior is that when any MFD sub-device is created for the first time (and matched with device tree node) it is added to the mfd_of_node_list. It looks like this list is never cleaned even if devices added there are intentionally removed from the system. So when MFD device is replugged and all sub-devices are matched with their device tree nodes again they fail as matched nodes already exist in mfd_of_node_list. In other words current implementation does not support MFD with hotplug feature. This commit extends MFD core for hotplugging support by removing appropriate OF node entry from mfd_of_node_list when corresponding device is removed from the system. Thanks to that when device is added once again it can be matched with its device tree node successfully. Signed-off-by:
