It already landed in your tree through the net pull request but here it is mentioned again. The most interesting is perhaps the Samsung Exynos subdrivers for the Tensor SoC used in Google Pixel 6 and the ExynosAuto subdriver for automotive. Along with the earlier merged Tesla FSD subdriver it shows some of the versatile uses of the Samsung Exynos silicon. It is also used in the latest version of Axis Communications ARTPEC chips so it is a very widely deployed SoC family. We also have the Intel Meteor Lake SoC which I think is for laptops. It's a pretty interesting chip with Xe graphics and integrated PCH. Core changes: - A new PINCTRL_GROUP_DESC() infrastructure macro is added and used in different drivers, generic group description struct group_desc is now used all over the place. New drivers: - New driver for the Texas Instruments TPS6494 Power Management IC. - New driver for the Lantic PEF2256 framer pin multiplexer. This IC has some pins that can be reconfigured in different ways. The actual driver comes on an immutable branch with the net WAN parts, the IC is some latest-and-greatest serial line funnel for e.g. wireless access points. - New subdriver for the Samsung Exynos Auto V920 pin controller, used for automotive applications. - New subdriver for the Samsung "GS101" SoC pin controller, this is the Google "Tensor" SoC used in the Google Pixel 6. - New subdriver for the Intel Meteor Point SoC pin controller. - New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS pin controllers. - New subdriver for the Qualcomm X1E80100 top level (TLMM) pin controller. - New subdriver for the Qualcomm SM4450 top level (TLMM) pin controller. - The "single" pin controller now supports the Texas Instruments J7200 SoC. Improvements: - Intel has created a new (Intel-)generic pin controller driver that is now used by all contemporary Intel platforms. - Intel is now also making use of some cleanup helpers. - Enble 910 Ohm bias in the Intel Tangier driver. - The Samsung driver now suppors irq_set_affinity() in it's IRQ chip giving support for non wake up external gpio interrupts" * tag 'pinctrl-v6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (112 commits) pinctrl: samsung: constify iomem pointers pinctrl: cy8c95x0: Cache muxed registers dt-bindings: pinctrl: xilinx: Rename *gpio to *gpio-grp pinctrl: qcom: lpass-lpi: remove duplicated include dt-bindings: pinctrl: qcom: drop common properties and allow wakeup-parent dt-bindings: pinctrl: qcom: drop common properties dt-bindings: pinctrl: qcom,ipq5018-tlmm: use common TLMM bindings dt-bindings: pinctrl: qcom,x1e80100-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,sm8650-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,sm8550-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,sdx75-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,sa8775p-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom,qdu1000-tlmm: restrict number of interrupts dt-bindings: pinctrl: qcom: create common LPASS LPI schema pinctrl: qcom: sm4450: dd SM4450 pinctrl driver dt-bindings: pinctrl: qcom: Add SM4450 pinctrl dt-bindings: pinctrl: qcom,pmic-mpp: clean up example pinctrl: intel: Add Intel Meteor Point pin controller and GPIO support pinctrl: renesas: rzg2l: Add input enable to the Ethernet pins pinctrl: renesas: rzg2l: Add output enable support ...
| * pinctrl: cy8c95x0: Cache muxed registersPatrick Rudolph2023-12-201-143/+315
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the port specific registers behind the PORTSEL mux aren't cached in the regmap and thus the typical setup time for a single pin on cy8c9560 is about 200msec on our system. The hotspot is the IRQ (un)masking, which causes lots of R/W operations. Introduce a separate regmap for muxed registers and helper functions to use the newly introduced regmap for muxed register access under the i2c lock. With the new cache in place the typical pin setup time is reduced to 20msec, making it about 10 times faster. As a side effect the system boot time is also reduced by 50%.

* pinctrl: cy8c95x0: Add reset supportPatrick Rudolph2023-07-201-0/+15
| | | | | | | | | | | | | | | | | | | This patch adds support for an optional "reset" GPIO pin in the cy8c95x0 pinctrl driver. On probe, the reset pin is pulled low to bring chip out of reset. The reset pin has an internal pull-down and can be left floating if not required. The datasheet doesn't mention any timing related to the reset pin. Based on empirical tests, it was found that the chip requires a delay of 250 milliseconds before accepting I2C transfers after driving the reset pin low. Therefore, a delay of 250ms is added before proceeding with I2C transfers.

| | | | | | | | | | | | | | Since recently, the kernel is nagging about mutable irq_chips: "not an immutable chip, please consider fixing it!" Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new helper functions and call the appropriate gpiolib functions.

* pinctrl: Add Cypress cy8c95x0 supportPatrick Rudolph2022-08-251-0/+1381
Add support for cypress I2C GPIO expanders cy8c9520, cy8c9540 and cy8c9560. The GPIO expanders feature a PWM mode, thus add it as pinctrl driver. The chip features multiple drive modes for each pin when configured as output and multiple bias settings when configured as input. Tested all three components and verified that all functionality is fully working.
