pinctrl: Add Intel Keem Bay pinctrl driver

2021-08-11T13:13:14+00:00

About Intel Keem Bay: ------------------- Intel Keem Bay is a computer vision AI accelerator SoC based on ARM CPU. Documentation of Keem Bay: Documentation/vpu/vpu-stack-overview.rst. Pinctrl IP: ---------- The SoC has a customised pinmux controller IP which controls pin multiplexing and configuration. Keem Bay pinctrl IP is not based on and have nothing in common with the existing pinctrl drivers. The registers used are incompatible with the existing drivers, so it requires a new driver. Add pinctrl driver to enable pin control support in the Intel Keem Bay SoC. Co-developed-by: Vineetha G. Jaya Kumaran Signed-off-by: Vineetha G.

pinctrl: zynqmp: some code cleanups

2021-06-25T23:44:19+00:00

Some minor code cleanups and updates which includes - Mention module name under help in Kconfig. - Remove extra lines and duplicate Pin range checks. - Replace 'return ret' with 'return 0' in success path. - Copyright year update. - use devm_pinctrl_register() instead pinctrl_register() in probe.

pinctrl: PINCTRL_ROCKCHIP should depend on ARCH_ROCKCHIP

2021-03-25T09:16:32+00:00

The Rockchip GPIO and pin control modules are only present on Rockchip SoCs. Hence add a dependency on ARCH_ROCKCHIP, to prevent asking the user about this driver when configuring a kernel without Rockchip platform support. Note that before, the PINCTRL_ROCKCHIP symbol was not visible, and automatically selected when needed. By making it tristate and user-selectable, it became visible for everyone.

Pull RISC-V updates from Palmer Dabbelt: "A handful of new RISC-V related patches for this merge window: - A check to ensure drivers are properly using uaccess. This isn't manifesting with any of the drivers I'm currently using, but may catch errors in new drivers. - Some preliminary support for the FU740, along with the HiFive Unleashed it will appear on. - NUMA support for RISC-V, which involves making the arm64 code generic. - Support for kasan on the vmalloc region. - A handful of new drivers for the Kendryte K210, along with the DT plumbing required to boot on a handful of K210-based boards. - Support for allocating ASIDs. - Preliminary support for kernels larger than 128MiB. - Various other improvements to our KASAN support, including the utilization of huge pages when allocating the KASAN regions. We may have already found a bug with the KASAN_VMALLOC code, but it's passing my tests. There's a fix in the works, but that will probably miss the merge window. * tag 'riscv-for-linus-5.12-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (75 commits) riscv: Improve kasan population by using hugepages when possible riscv: Improve kasan population function riscv: Use KASAN_SHADOW_INIT define for kasan memory initialization riscv: Improve kasan definitions riscv: Get rid of MAX_EARLY_MAPPING_SIZE soc: canaan: Sort the Makefile alphabetically riscv: Disable KSAN_SANITIZE for vDSO riscv: Remove unnecessary declaration riscv: Add Canaan Kendryte K210 SD card defconfig riscv: Update Canaan Kendryte K210 defconfig riscv: Add Kendryte KD233 board device tree riscv: Add SiPeed MAIXDUINO board device tree riscv: Add SiPeed MAIX GO board device tree riscv: Add SiPeed MAIX DOCK board device tree riscv: Add SiPeed MAIX BiT board device tree riscv: Update Canaan Kendryte K210 device tree dt-bindings: add resets property to dw-apb-timer dt-bindings: fix sifive gpio properties dt-bindings: update sifive uart compatible string dt-bindings: update sifive clint compatible string ...

pinctrl: Add RISC-V Canaan Kendryte K210 FPIOA driver

2021-02-19T07:18:01+00:00

Add the pinctrl-k210.c pinctrl driver for the Canaan Kendryte K210 field programmable IO array (FPIOA) to allow configuring the SoC pin functions. The K210 has 48 programmable pins which can take any of 256 possible functions. This patch is inspired from the k210 pinctrl driver for the u-boot project and contains many direct contributions from Sean Anderson. The MAINTAINERS file is updated, adding the entry "CANAAN/KENDRYTE K210 SOC FPIOA DRIVER" with myself listed as maintainer for this driver.
