2024-06-17pinctrl: rockchip: fix pinmux reset in rockchip_pmx_setHuang-Huang Bao
rockchip_pmx_set reset all pinmuxs in group to 0 in the case of error, add missing bank data retrieval in that code to avoid setting mux on unexpected pins.

2024-06-17pinctrl: rockchip: use dedicated pinctrl type for RK3328Huang-Huang Bao
rk3328_pin_ctrl uses type of RK3288 which has a hack in rockchip_pinctrl_suspend and rockchip_pinctrl_resume to restore GPIO6-C6 at assume, the hack is not applicable to RK3328 as GPIO6 is not even exist in it. So use a dedicated pinctrl type to skip this hack.

2024-06-17pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFERHagar Hemdan
In create_pinctrl(), pinctrl_maps_mutex is acquired before calling add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl() calls pinctrl_free(). However, pinctrl_free() attempts to acquire pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to a potential deadlock. This patch resolves the issue by releasing pinctrl_maps_mutex before calling pinctrl_free(), preventing the deadlock. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.

2024-06-17pinctrl: qcom: spmi-gpio: drop broken pm8008 supportJohan Hovold
The SPMI GPIO driver assumes that the parent device is an SPMI device and accesses random data when backcasting the parent struct device pointer for non-SPMI devices. Fortunately this does not seem to cause any issues currently when the parent device is an I2C client like the PM8008, but this could change if the structures are reorganised (e.g. using structure randomisation). Notably the interrupt implementation is also broken for non-SPMI devices. Also note that the two GPIO pins on PM8008 are used for interrupts and reset so their practical use should be limited. Drop the broken GPIO support for PM8008 for now.

2024-05-06pinctrl: bcm2835: Make pin freeing behavior configurableStefan Wahren
Until now after a bcm2835 pin was freed its pinmux was set to GPIO_IN. So in case it was configured as GPIO_OUT before the configured output level also get lost. As long as GPIO sysfs was used this wasn't actually a problem because the pins and their possible output level were kept by sysfs. Since more and more Raspberry Pi users start using libgpiod they are confused about this behavior. So make the pin freeing behavior of GPIO_OUT configurable via module parameter. In case pinctrl-bcm2835.persist_gpio_outputs is set to 1, the output level is kept. This patch based on the downstream work of Phil Elwell.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.10 1. Basic support for SCMI v3.2 pincontrol protocol SCMI v3.2 introduces pincontrol protocol which is intended for controlling pins and their configuration. The pin control protocol provides commands to: - List the pins, groups of pins, available functions, and their association with each other. - Set the parameter configuration and multiplexing of the pins or groups of pins - Optionally request exclusive access to a pin or group of pins. - Optionally configure the permissions of an agent to access a pin or group of pins. These changes adds basic support for the same in the SCMI core layer and an implementation of the generic scmi-pinctrl driver with associated DT bindings. 2. Framework support for multiple vendors custom protocols With the fixed space for vendor protocols, the possibility of having multiple vendors implementing distinct SCMI vendor protocols with the same overlapping protocol number is very high and with the need to support them all in a single kernel image or a module is also high. In order to implement the same we assume: - vendor protocols has to be tagged at build time with a vendor_id - vendor protocols could also optionally be tagged at build time with sub_vendor_id and implementation version At the initialisation all the built vendor protocols are registered with the SCMI core using a key derived from the above tags 3. Logging and tracing improvements This includes using dev_err_probe() to bail out from probe, adding message dump traces for bad and unexpected replies and widening of the tag buffer in trace_scmi_dump_msg to allow diverse tag names 4. Miscellaneous updates or improvements This includes adding the accessor function get_max_msg_size() used in pinctl protocol, updation of dt-bindings examples for protocol@13 to promote new bindings and simplification of scmi_devm_notifier_unregister * tag 'scmi-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: pinctrl: Implementation of the generic scmi-pinctrl driver firmware: arm_scmi: Add basic support for SCMI v3.2 pincontrol protocol dt-bindings: firmware: Support SCMI pinctrl protocol firmware: arm_scmi: Introduce get_max_msg_size() helper/accessor firmware: arm_scmi: Add support for multiple vendors custom protocols dt-bindings: firmware: arm,scmi: Update examples for protocol@13 firmware: arm_scmi: Avoid non-constant printk format strings firmware: arm_scmi: Use dev_err_probe to bail out firmware: arm_scmi: Simplify scmi_devm_notifier_unregister firmware: arm_scmi: Add message dump traces for bad and unexpected replies firmware: arm_scmi: Add helper to trace bad messages include: trace: Widen the tag buffer in trace_scmi_dump_msg firmware: arm_scmi: Log the perf domain names in the error paths Link: https://lore.kernel.org/r/20240426105031.1526987-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The RZ/G3S SoC supports configurable supply voltages for several of its I/O interfaces. All of these interfaces support both 1.8V and 3.3V supplies, but only the Ethernet and XSPI interfaces support a 2.5V supply. Voltage selection for the XSPI interface is not yet supported, so this leaves only the Ethernet interfaces currently supporting selection of a 2.5V supply. So we need to return an error if there is an attempt to select a 2.5V supply for any non-Ethernet interface.

2024-04-08pinctrl: baytrail: Fix selecting gpio pinctrl stateHans de Goede
For all the "score" pin-groups all the intel_pingroup-s to select the non GPIO function are re-used for byt_score_gpio_groups[]. But this is incorrect since a pin-group includes the mode setting, which for the non GPIO functions generally is 1, where as to select the GPIO function mode must be set to 0. So the GPIO function needs separate intel_pingroup-s with their own mode value of 0. Add a new PIN_GROUP_GPIO macro which adds a foo_gpio entry to each pin-group defined this way and update byt_score_gpio_groups[] to point to the new foo_gpio entries. The "sus" usb_oc_grp usb_ulpi_grp and pcu_spi_grp pin-groups are special because these have a non 0 mode value to select the GPIO functions and these already have matching foo_gpio pin-groups, leave these are unchanged. The pmu_clk "sus" groups added in commit 2f46d7f7e959 ("pinctrl: baytrail: Add pinconf group + function for the pmu_clk") do need to use the new PIN_GROUP_GPIO macro.

2024-04-04pinctrl: single: Fix PIN_CONFIG_BIAS_DISABLE handlingMatthijs Kooijman
The pinctrl-single driver handles pin_config_set by looking up the requested setting in a DT-defined lookup table, which defines what bits correspond to each setting. There is no way to add PIN_CONFIG_BIAS_DISABLE entries to the table, since there is instead code to disable the bias by applying the disable values of both the pullup and pulldown entries in the table. However, this code is inside the table-lookup loop, so it would only execute if there is an entry for PIN_CONFIG_BIAS_DISABLE in the table, which can never exist, so this code never runs. This commit lifts the offending code out of the loop, so it just executes directly whenever PIN_CONFIG_BIAS_DISABLE is requested, skippipng the table lookup loop. This also introduces a new `param` variable to make the code slightly more readable. This bug seems to have existed when this code was first merged in commit 9dddb4df90d13 ("pinctrl: single: support generic pinconf"). Earlier versions of this patch did have an entry for PIN_CONFIG_BIAS_DISABLE in the lookup table, but that was removed, which is probably how this bug was introduced.
