2026-09-30pinctrl: nuvoton: Fix clock reference leak in ma35_get_bank_data()Wentao Liang
ma35_get_bank_data() obtains the bank clock with of_clk_get() and stores it in bank->clk, but returns clk_prepare_enable() directly. If that call fails, the reference taken by of_clk_get() is never dropped, and the driver has no other clk_put() for it. Drop the reference when clk_prepare_enable() fails.

2026-07-24pinctrl: npcm8xx: fix debounce register selectionTomer Maimon
Each DBNCS register programs debounce source selection for 16 GPIOs. The current offset calculation advances the register address every four GPIOs, so offsets 4-15 and 20-31 end up touching the wrong selector register. Advance the DBNCS offset per 16 GPIOs so each line uses the debounce selector bank that matches the hardware layout.

Pins 136-140 and 142 are currently advertised as having both drive- strength and slew-rate controls, while pins 141 and 143 expose no slew control at all.

A bank may retain pending event status across resets of the GPIO block. If probe leaves the old state in place, the chained IRQ handler can see spurious events as soon as the irqchip is registered.

RG2 pins 110-113 and 208-209 do not use the per-bank ODSC bit that the driver relies on for the rest of the drive-strength handling. Their strength is encoded in GCR_DSCNT[7:6] and supports four values: 8, 12, 16 and 24mA.

NPCM8xx uses GCR_INTCR4 bits to release the R1, R2 and RMII3 transmit outputs from Hi-Z. Those bits need to follow the mandatory r1, r2 and rmii3 pin groups. The R1_OEn, R2_OEn and R3_OEn side groups are optional and should not be required just to enable RMII transmit outputs.

2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2025-09-08pinctrl: generic: rename PIN_CONFIG_OUTPUT to LEVELLinus Walleij
This generic pin config property is confusingly named so let's rename it to make things clearer. There are already drivers in the tree that use PIN_CONFIG_OUTPUT to *read* the value of an output driven pin, which is a big semantic confusion for the head: are we then reading the setting of the output or the actual value/level that is put out on the pin? We already have PIN_CONFIG_OUTPUT_ENABLE that turns on driver buffers for output, so this can by logical conclusion only drive the voltage level if it should be any different. But if we read the pin, are we then reading the *setting* of the output value or the *actual* value we can see on the line? If the pin has not first been set into output mode with PIN_CONFIG_OUTPUT_ENABLE, but is instead in some input mode or tristate, what will reading this property actually return? Reading the current users reading this property it is clear that what we read is the logical level of the pin as 0 or 1 depending on if it is low or high. Rename it to PIN_CONFIG_LEVEL so it is crystal clear that we set or read the voltage level of the pin and nothing else.

2025-06-18pinctrl: nuvoton: Fix boot on ma35dx platformsMiquel Raynal
As part of a wider cleanup trying to get rid of OF specific APIs, an incorrect (and partially unrelated) cleanup was introduced. The goal was to replace a device_for_each_chil_node() loop including an additional condition inside by a macro doing both the loop and the check on a single line. The snippet: device_for_each_child_node(dev, child) if (fwnode_property_present(child, "gpio-controller")) continue; was replaced by: for_each_gpiochip_node(dev, child) which expands into: device_for_each_child_node(dev, child) for_each_if(fwnode_property_present(child, "gpio-controller")) This change is actually doing the opposite of what was initially expected, breaking the probe of this driver, breaking at the same time the whole boot of Nuvoton platforms (no more console, the kernel WARN()).

Some drivers are using device property APIs along with OF-specific ones. At the same time few of the latter can be converted to device property calls. Reduce use of OF-specific APIs in order to bring a bit more consistency into the drivers.

This is not a problem as the pin numbering repeats the natural order, but it might be in case of shuffling the entries. Fix this by adding missed equal sign and reformat a bit for better readability.

'new_map' is allocated using devm_* which takes care of freeing the allocated data on device removal, call to .dt_free_map = pinconf_generic_dt_free_map double frees the map as pinconf_generic_dt_free_map() calls pinctrl_utils_free_map().
