2021-02-12pinctrl: at91-pio4: add support for slew-rateClaudiu Beznea
SAMA7G5 supports slew rate configuration. Adapt the driver for this. For output switching frequencies lower than 50MHz the slew rate needs to be enabled. Since most of the pins on SAMA7G5 fall into this category enabled the slew rate by default.

2021-01-18pinctrl: qcom: Don't clear pending interrupts when enablingDouglas Anderson
In Linux, if a driver does disable_irq() and later does enable_irq() on its interrupt, I believe it's expecting these properties: * If an interrupt was pending when the driver disabled then it will still be pending after the driver re-enables. * If an edge-triggered interrupt comes in while an interrupt is disabled it should assert when the interrupt is re-enabled. If you think that the above sounds a lot like the disable_irq() and enable_irq() are supposed to be masking/unmasking the interrupt instead of disabling/enabling it then you've made an astute observation. Specifically when talking about interrupts, "mask" usually means to stop posting interrupts but keep tracking them and "disable" means to fully shut off interrupt detection. It's unfortunate that this is so confusing, but presumably this is all the way it is for historical reasons. Perhaps more confusing than the above is that, even though clients of IRQs themselves don't have a way to request mask/unmask vs. disable/enable calls, IRQ chips themselves can implement both. ...and yet more confusing is that if an IRQ chip implements disable/enable then they will be called when a client driver calls disable_irq() / enable_irq(). It does feel like some of the above could be cleared up. However, without any other core interrupt changes it should be clear that when an IRQ chip gets a request to "disable" an IRQ that it has to treat it like a mask of that IRQ. In any case, after that long interlude you can see that the "unmask and clear" can break things. Maulik tried to fix it so that we no longer did "unmask and clear" in commit 71266d9d3936 ("pinctrl: qcom: Move clearing pending IRQ to .irq_request_resources callback"), but it only handled the PDC case and it had problems (it caused sc7180-trogdor devices to fail to suspend). Let's fix. >From my understanding the source of the phantom interrupt in the were these two things: 1. One that could have been introduced in msm_gpio_irq_set_type() (only for the non-PDC case). 2. Edges could have been detected when a GPIO was muxed away. Fixing case #1 is easy. We can just add a clear in msm_gpio_irq_set_type(). Fixing case #2 is harder. Let's use a concrete example. In sc7180-trogdor.dtsi we configure the uart3 to have two pinctrl states, sleep and default, and mux between the two during runtime PM and system suspend (see geni_se_resources_{on,off}() for more details). The difference between the sleep and default state is that the RX pin is muxed to a GPIO during sleep and muxed to the UART otherwise. As per Qualcomm, when we mux the pin over to the UART function the PDC (or the non-PDC interrupt detection logic) is still watching it / latching edges. These edges don't cause interrupts because the current code masks the interrupt unless we're entering suspend. However, as soon as we enter suspend we unmask the interrupt and it's counted as a wakeup. Let's deal with the problem like this: * When we mux away, we'll mask our interrupt. This isn't necessary in the above case since the client already masked us, but it's a good idea in general. * When we mux back will clear any interrupts and unmask.

2021-01-18pinctrl: qcom: Properly clear "intr_ack_high" interrupts when unmaskingDouglas Anderson
In commit 4b7618fdc7e6 ("pinctrl: qcom: Add irq_enable callback for msm gpio") we tried to Ack interrupts during unmask. However, that patch forgot to check "intr_ack_high" so, presumably, it only worked for a certain subset of SoCs. Let's add a small accessor so we don't need to open-code the logic in both places. This was found by code inspection. I don't have any access to the hardware in question nor software that needs the Ack during unmask.

2021-01-18pinctrl: qcom: No need to read-modify-write the interrupt statusDouglas Anderson
When the Qualcomm pinctrl driver wants to Ack an interrupt, it does a read-modify-write on the interrupt status register. On some SoCs it makes sure that the status bit is 1 to "Ack" and on others it makes sure that the bit is 0 to "Ack". Presumably the first type of interrupt controller is a "write 1 to clear" type register and the second just let you directly set the interrupt status register. As far as I can tell from scanning structure definitions, the interrupt status bit is always in a register by itself. Thus with both types of interrupt controllers it is safe to "Ack" interrupts without doing a read-modify-write. We can do a simple write. It should be noted that if the interrupt status bit _was_ ever in a register with other things (like maybe status bits for other GPIOs): a) For "write 1 clear" type controllers then read-modify-write would be totally wrong because we'd accidentally end up clearing interrupts we weren't looking at. b) For "direct set" type controllers then read-modify-write would also be wrong because someone setting one of the other bits in the register might accidentally clear (or set) our interrupt. I say this simply to show that the current read-modify-write doesn't provide any sort of "future proofing" of the code. In fact (for "write 1 clear" controllers) the new code is slightly more "future proof" since it would allow more than one interrupt status bits to share a register. NOTE: this code fixes no bugs--it simply avoids an extra register read.

2021-01-14pinctrl: renesas: Implement unlock register masksUlrich Hecht
The V3U SoC has several unlock registers, one per register group. They reside at offset zero in each 0x200 bytes-sized block. To avoid adding yet another table to the PFC implementation, this patch adds the option to specify an address mask instead of the fixed address in sh_pfc_soc_info::unlock_reg.

2021-01-12pinctrl: renesas: checker: Restrict checks to Renesas platformsGeert Uytterhoeven
When DEBUG is defined (e.g. if CONFIG_DEBUG_PINCTRL=y), the Renesas pin control driver runs sanity checks against the pin control tables. This may cause lots of output on the console, and can be annoying in ARM multi-platform kernels. Fix this by only running the checks when running on SuperH, or on a DT platform supported by the Renesas pin controller driver.

2021-01-08pinctrl: intel: Split intel_pinctrl_add_padgroups() for better maintenanceAndy Shevchenko
Currently the intel_pinctrl_add_padgroups() is twisted a bit due to a different nature of the pin control hardware implementations. Thus, its maintenance is a bit hard. Besides that some pieces of code are run on all hardware and make this code slightly inefficient, and moreover, validation for one case is done in a wrong time in a flow which makes it even slower. Split intel_pinctrl_add_padgroups() to two functions, one per hardware implementation, for better maintenance and readability.

2021-01-06pinctrl: sunxi: h6-r: Add s_rsb pin functionsSamuel Holland
As there is an RSB controller in the H6 SoC, there should be some pin configuration for it. While no such configuration is documented, the "s_i2c" pins are suspiciously on the "alternate" function 3, with no primary function 2 given. This suggests the primary function for these pins is actually RSB, and that is indeed the case. Add the "s_rsb" pin functions so the RSB controller can be used.
