The semantic of mcp_set_mask() was surprising to me when I first read that driver. So it was unexpected that in the call mcp_set_mask(mcp, MCP_OLAT, mask, value); value was a bool. Make the function a thinner wrapper around regmap_update_bits() and rename it to also have a similar name. Signed-off-by:

The Qualcomm pinctrl driver has been violating the documented meaning of PIN_CONFIG_INPUT_ENABLE. That documentation says: Note that this does not affect the pin's ability to drive output. ...yet the Qualcomm driver's sole action when asked to "enable input" on a pin is to disable its output. The Qualcomm driver's implementation stems from the fact that "output-disable" is a "new" property from 2017. It was introduced in commit 42556242 ("pinctrl: generic: Add output-enable property"). The "input-enable" handling in Qualcomm drivers is from 2015 introduced in commit 407f5e39 ("pinctrl: qcom: handle input-enable pinconf property"). Let's change the Qualcomm driver to move us in the right direction. As part of this: 1. We'll now support PIN_CONFIG_OUTPUT_ENABLE 2. We'll still support using PIN_CONFIG_INPUT_ENABLE to disable a pin's output (in violation of the docs) with a big comment in the code. This is needed because old device trees have "input-enable" in them and, in some cases, people might need the old behavior. While we could programmatically change all old device trees, it doesn't really hurt to keep supporting the old behavior and we're _supposed_ to try to be compatible with old device trees anyway. It can also be noted that the PIN_CONFIG_INPUT_ENABLE handling code seems to have purposefully ignored its argument. That means that old boards that had _either_ "input-disable" or "input-enable" in them would have had the effect of disabling a pin's output. While we could change this behavior, since we're only leaving the PIN_CONFIG_INPUT_ENABLE there for backward compatibility we might as well be fully backward compatible. NOTE: despite the fact that we'll still support PIN_CONFIG_INPUT_ENABLE for _setting_ config, we take it away from msm_config_group_get(). This appears to be only used for populating debugfs and fixing debugfs to "output enabled" where relevant instead of "input enabled" makes more sense and has more truthiness. Signed-off-by:

In the patch ("dt-bindings: pinctrl: qcom: tlmm should use output-disable, not input-enable") we allowed setting "output-disable" for TLMM pinctrl states. Let's also add "output-enable". At first blush this seems a needless thing to do. Specifically: - In Linux (and presumably any other OSes using the same device trees) the GPIO/pinctrl driver knows to automatically enable the output when a GPIO is changed to an output. Thus in most cases specifying "output-enable" is superfluous and should be avoided. - If we need to set a pin's default state we already have "output-high" and "output-low" and these properties already imply "output-enabled" (at least on the Linux Qualcomm TLMM driver). However, there is one instance where "output-enable" seems like it could be useful: sleep states. It's not uncommon to want to configure pins as inputs (with appropriate pulls) when the driver controlling them is in a low power state. Then we want the pins back to outputs when the driver wants things running normally. To accomplish this we'd want to be able to use "output-enable". Then the "default" state could have "output-enable" and the "sleep" state could have "output-disable". NOTE: in all instances I'm aware of, we'd only want to use "output-enable" on pins that are configured as "gpio". The Qualcomm documentation that I have access to says that "output-enable" only does something useful when in GPIO mode. Signed-off-by:Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Acked-by:

As evidenced by the Qualcomm TLMM Linux driver, the TLMM IP block in Qualcomm SoCs has a bit to enable/disable the output for a pin that's configured as a GPIO but _not_ a bit to enable/disable an input buffer. Current device trees that are specifying "input-enable" for pins managed by TLMM are either doing so needlessly or are using it to mean "output-disable". Presumably the current convention of using "input-enable" to mean "output-disable" stems from the fact that "output-disable" is a "new" property from 2017. It was introduced in commit 42556242 ("pinctrl: generic: Add output-enable property"). The "input-enable" handling in Qualcomm drivers is from 2015 introduced in commit 407f5e39 ("pinctrl: qcom: handle input-enable pinconf property"). Given that there's no other use for "input-enable" for TLMM, we can still handle old device trees in code, but let's encourage people to move to the proper / documented property by updating the bindings.

It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.
