git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO development for the v5.7 kernel cycle. Core and userspace API: - The userspace API KFIFOs have been imoproved with locks that do not block interrupts. This makes us better at getting events to userspace without blocking or disturbing new events arriving in the same time. This was reviewed by the KFIFO maintainer Stefani. This is a generic improvement which paves the road for similar improvements in other subsystems. - We provide a new ioctl() for monitoring changes in the line information, such as when multiple clients are taking lines and giving them back, possibly reconfiguring them in the process: we can now monitor that and not get stuck with stale static information. - An example tool 'gpio-watch' is provided to showcase this functionality. - Timestamps for events are switched to ktime_get_ns() which is monotonic. We previously had a 'realtime' stamp which could move forward and *backward* in time, which probably would just cause silent bugs and weird behaviour. In the long run we see two relevant timestamps: ktime_get_ns() or the timestamp sometimes provided by the GPIO hardware itself, if that exists. - Device Tree overlay support for GPIO hogs. On systems that load overlays, these overlays can now contain hogs, and will then be respected. - Handle pin control interaction with nonexisting pin ranges in the GPIO library core instead of in the individual drivers. New drivers: - New driver for the Mellanox BlueField 2 GPIO controller. Driver improvements: - Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic MMIO GPIO library and use this flag in the MT7621 driver. - Texas Instruments OMAP CPU power management improvements, such as blocking of idle on pending GPIO interrupts" * tag 'gpio-v5.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (59 commits) Revert "gpio: eic-sprd: Use devm_platform_ioremap_resource()" pinctrl: Unconditionally assign .request()/.free() gpio: Unconditionally assign .request()/.free() gpio: export of_pinctrl_get to modules pinctrl: Define of_pinctrl_get() dummy for !PINCTRL gpio: Rename variable in core APIs gpio: Avoid using pin ranges with !PINCTRL gpiolib: Remove unused gpio_chip parameter from gpio_set_bias() gpiolib: Pass gpio_desc to gpio_set_config() gpiolib: Introduce gpiod_set_config() tools: gpio: Fix out-of-tree build regression gpio: gpiolib: fix a doc warning gpio: tegra186: Add Tegra194 pin ranges for GG.0 and GG.1 gpio: tegra186: Add support for pin ranges gpio: Support GPIO controllers without pin-ranges ARM: integrator: impd1: Use GPIO_LOOKUP() helper macro gpio: brcmstb: support gpio-line-names property tools: gpio: Fix typo in gpio-utils tools: gpio-hammer: Apply scripts/Lindent and retain good changes gpiolib: gpio_name_to_desc: factor out !name check ...

2020-02-27ARM: OMAP2+: pm33xx-core: Extend platform_data ops for cpuidleDave Gerlach
In order for am335x and am437x to properly enter deeper c-states in cpuidle they must always call into the sleep33/43xx suspend code and also sometimes invoke the wkup_m3_ipc driver. These are both controlled by the pm33xx module so we must provide a method for the platform code to call back into the module when it is available as the core cpuidle ops that are invoked by the cpuidle-arm driver must remain as built in. Extend the init platform op to take an idle function as an argument so that we can use this to call into the pm33xx module for c-states that need it. Also add a deinit op so we can unregister this idle function from the PM core when the pm33xx module gets unloaded.

2020-02-27ARM: OMAP2+: pm33xx-core: Add cpuidle_ops for am335x/am437xDave Gerlach
am335x and am437x can now make use of the generic cpuidle-arm driver. This requires that we define init and suspend ops to be passed set as the cpuidle ops for the SoC. These ops are invoked directly at the last stage of the cpuidle-arm driver in order to allow low level platform code to run and bring the CPU the rest of the way into it's desired idle state. It is required that the CPUIDLE_METHOD_OF_DECLARE be called from code that is built in so define these ops in pm33xx-core where the always built-in portion of the PM code for these SoCs lives. Additionally, although an soc_suspend function is already exposed by the pm33xx platform code, it contains additional operations needed for full SoC suspend beyond what is needed for a relatively simple CPU suspend needed during cpuidle. To get around this introduce cpu_suspend ops to be used by the am335x and am437x PM driver for the last stage of cpuidle path.

2020-02-26bus: ti-sysc: Implement SoC revision handlingTony Lindgren
We need to know SoC type and features for cases where the same SoC may be installed in various versions on the same board and would need a separate dts file otherwise for the different variants. For example, am3703 is pin compatible with omap3630, but has sgx and iva accelerators disabled. We must not try to access the sgx or iva module registers on am3703, and need to set the unavailable devices disabled early. Let's also detect omap3430 as that is needed for display subsystem (DSS) reset later on, and GP vs EMU or HS devices. Further SoC specific disabled device detection can be added as needed, such as dra71x vs dra76x rtc and usb4. Cc: Adam Ford <aford173@gmail.com> Cc: André Hentschel <nerv@dawncrow.de> Cc: H.

2020-01-23ARM: OMAP: DRA7xx: Make CAM clock domain SWSUP onlyBenoit Parrot
Both CAL and VIP rely on this clock domain. But CAL DPHY require LVDSRX_96M_GFCLK to be active. When this domain is set to HWSUP the LVDSRX_96M_GFCLK is on;y active when VIP1 clock is also active. If only CAL on DRA72x (which uses the VIP2 clkctrl) probes the CAM domain is enabled but the LVDSRX_96M_GFCLK is left gated. Since LVDSRX_96M_GFCLK is sourcing the input clock to the DPHY then actual frame capture cannot start as the phy are inactive. So we either have to also enabled VIP1 even if we don't intend on using it or we need to set the CAM domain to use SWSUP only. This patch implements the latter.

2020-01-13ARM: OMAP2+: sleep43xx: Call secure suspend/resume handlersAndrew F. Davis
During suspend CPU context may be lost in both non-secure and secure CPU states. The kernel can handle saving and restoring the non-secure context but must call into the secure side to allow it to save any context it may lose. Add these calls here. Note that on systems with OP-TEE available the suspend call is issued to OP-TEE using the ARM SMCCC, but the resume call is always issued to the ROM. This is because on waking from suspend the ROM is restored as the secure monitor. It is this resume call that instructs the ROM to restore OP-TEE, all subsequent calls will be handled by OP-TEE and should use the ARM SMCCC. Signed-off-by: Andrew F.

2020-01-13ARM: OMAP2+: Use ARM SMC Calling Convention when OP-TEE is availableAndrew F. Davis
On High-Security(HS) OMAP2+ class devices a couple actions must be performed from the ARM TrustZone during boot. These traditionally can be performed by calling into the secure ROM code resident in this secure world using legacy SMC calls. Optionally OP-TEE can replace this secure world functionality by replacing the ROM after boot. ARM recommends a standard calling convention is used for this interaction (SMC Calling Convention). We check for the presence of OP-TEE and use this type of call to perform the needed actions, falling back to the legacy OMAP ROM call if OP-TEE is not available. Signed-off-by: Andrew F.
