pinctrl: qcom: Add sm8250 lpass lpi pinctrl driver

2020-12-05T22:36:24Z

Add initial pinctrl driver to support pin configuration for LPASS (Low Power Audio SubSystem) LPI (Low Power Island) pinctrl on SM8250. This IP is an additional pin control block for Audio Pins on top the existing SoC Top level pin-controller. Hardware setup looks like: TLMM GPIO[146 - 159] --> LPASS LPI GPIO [0 - 13] This pin controller has some similarities compared to Top level msm SoC Pin controller like 'each pin belongs to a single group' and so on. However this one is intended to control only audio pins in particular, which can not be configured/touched by the Top level SoC pin controller except setting them as gpios. Apart from this, slew rate is also available in this block for certain pins which are connected to SLIMbus or SoundWire Bus.

One fixup following my patch commit be117ca32261 ("pinctrl: qcom: Kconfig: Rework PINCTRL_MSM to be a depenency rather then a selected config") being queued in LinusW's tree, as a new config entry was added for the msm8953 that also needs the change.

pinctrl: qcom: Allow pinctrl-msm code to be loadable as a module

2020-11-10T13:58:15Z

Tweaks to allow pinctrl-msm code to be loadable as a module. This is needed in order to support having the qcom-scm driver, which pinctrl-msm calls into, configured as a module. This requires that we tweak Kconfigs selecting PINCTRL_MSM to also depend on QCOM_SCM || QCOM_SCM=n so that we match the module setting of QCOM_SCM.

pinctrl: qcom: Kconfig: Rework PINCTRL_MSM to be a depenency rather then a selected config

2020-11-10T13:58:14Z

This patch reworks PINCTRL_MSM to be a visible option, and instead of having the various SoC specific drivers select PINCTRL_MSM, this switches those configs to depend on PINCTRL_MSM. This is useful, as it will be needed in order to cleanly support having the qcom-scm driver, which pinctrl-msm calls into, configured as a module. Without this change, we would eventually have to add dependency lines to every config that selects PINCTRL_MSM, and that would becomes a maintenance headache. We also add PINCTRL_MSM to the arm64 defconfig to avoid surprises as otherwise PINCTRL_MSM/IPQ* options previously enabled, will be off.

pinctrl: qcom: Handle broken/missing PDC dual edge IRQs on sc7180

2020-07-16T13:41:41Z

Depending on how you look at it, you can either say that: a) There is a PDC hardware issue (with the specific IP rev that exists on sc7180) that causes the PDC not to work properly when configured to handle dual edges. b) The dual edge feature of the PDC hardware was only added in later HW revisions and thus isn't in all hardware. Regardless of how you look at it, let's work around the lack of dual edge support by only ever letting our parent see requests for single edge interrupts on affected hardware. NOTE: it's possible that a driver requesting a dual edge interrupt might get several edges coalesced into a single IRQ. For instance if a line starts low and then goes high and low again, the driver that requested the IRQ is not guaranteed to be called twice. However, it is guaranteed that once the driver's interrupt handler starts running its first instruction that any new edges coming in will cause the interrupt to fire again. This is relatively commonplace for dual-edge gpio interrupts (many gpio controllers require software to emulate dual edge with single edge) so client drivers should be setup to handle it.
