From cf9610f9116d55c5a66ef9f1faecacabd93a9322 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 24 Aug 2026 08:46:03 -0700 Subject: Merge tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Core changes: - Use the non-blocking mux_state_try_select() in the generic MUX pin control back-end - Free pin maps on pinctrl_generic_to_map() failure in the core helpers New hardware pin control: - Qualcomm Maili TLMM SoC, PMG1110 PMIC, and Eliza LPASS LPI TLMM SoC (this is for the low power audio, LPASS = Low Power Audio SubSystem portions) - Upboard support on top of the Intel pin controller - Apple T6030 and T6031 support (just compatible strings) - Samsung Exynos 8855 SoC - Mediatek MT6858 SoC - Rockchip RK3308B and RV1106 SoCs - Airoha EN7523 and AN7563 SoCs Improvements: - Qualcomm TLMM GPIOs are unconditionally marked as wakeup capable - Qualcomm improvements on top of the Qualcomm PDC (power domain controller) irqchip improvements from tglx:s tree - Qualcomm IPQ806x and IPQ9650 non-urgent pin grop fixups - The NPCM8xx driver has been put into shape fixing many pin and group definitions - Some non-urgent Tegra 264 pin assignments are fixed up - Some non-urgent fixups to Airoha AN7581 and AN7583 registers and pin assignments, missing features etc" * tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (130 commits) dt-bindings: pinctrl: Convert TI DA850 pupd to DT schema pinctrl: meson: sync some modify from A4 pinctrl: meson: a4: Add input enable pin configuration pinctrl: realtek: rtd1625: remove unused group name spdif_sel pinctrl: realtek: rtd1625: fix base_bit for VE4 GPIO 13 dt-bindings: pinctrl: microchip,pic32mzda-pinctrl: Convert to DT schema Revert "Merge branch 'ib-rsk7204' into devel" pinctrl: rockchip: Add RV1106 pinctrl support dt-bindings: pinctrl: rockchip: Add RV1106 compatible pinctrl: rockchip: Decode drive strength in the get function pinctrl: fix PINCTRL_GENERIC_MUX not always being selectable pinctrl: airoha: add support of an7563 SoC dt-bindings: pinctrl: airoha: add support of an7563 pin controller pinctrl: airoha: try to find chip scu node by phandle first pinctrl: airoha: add support of en7523 SoC dt-bindings: pinctrl: airoha: add support of en7523 pin controller pinctrl: airoha: an7583: add support for olt pinmux pinctrl: airoha: an7583: add support for pon_alt pinmux pinctrl: airoha: an7583: add support for npu_uart pinmux dt-bindings: pinctrl: airoha: an7583: add missed features ... --- drivers/input/touchscreen/tsc2005.c | 89 +++++++++++++++++++++++++++++++++++++ 1 file changed, 89 insertions(+) create mode 100644 drivers/input/touchscreen/tsc2005.c (limited to 'drivers/input/touchscreen/tsc2005.c') diff --git a/drivers/input/touchscreen/tsc2005.c b/drivers/input/touchscreen/tsc2005.c new file mode 100644 index 000000000..6fe8b41b3 --- /dev/null +++ b/drivers/input/touchscreen/tsc2005.c @@ -0,0 +1,89 @@ +// SPDX-License-Identifier: GPL-2.0-or-later +/* + * TSC2005 touchscreen driver + * + * Copyright (C) 2006-2010 Nokia Corporation + * Copyright (C) 2015 QWERTY Embedded Design + * Copyright (C) 2015 EMAC Inc. + * + * Based on original tsc2005.c by Lauri Leukkunen + */ + +#include +#include +#include +#include +#include +#include "tsc200x-core.h" + +static const struct input_id tsc2005_input_id = { + .bustype = BUS_SPI, + .product = 2005, +}; + +static int tsc2005_cmd(struct device *dev, u8 cmd) +{ + u8 tx = TSC200X_CMD | TSC200X_CMD_12BIT | cmd; + struct spi_transfer xfer = { + .tx_buf = &tx, + .len = 1, + .bits_per_word = 8, + }; + struct spi_message msg; + struct spi_device *spi = to_spi_device(dev); + int error; + + spi_message_init(&msg); + spi_message_add_tail(&xfer, &msg); + + error = spi_sync(spi, &msg); + if (error) { + dev_err(dev, "%s: failed, command: %x, spi error: %d\n", + __func__, cmd, error); + return error; + } + + return 0; +} + +static int tsc2005_probe(struct spi_device *spi) +{ + int error; + + spi->mode = SPI_MODE_0; + spi->bits_per_word = 8; + if (!spi->max_speed_hz) + spi->max_speed_hz = TSC2005_SPI_MAX_SPEED_HZ; + + error = spi_setup(spi); + if (error) + return error; + + return tsc200x_probe(&spi->dev, spi->irq, &tsc2005_input_id, + devm_regmap_init_spi(spi, &tsc200x_regmap_config), + tsc2005_cmd); +} + +#ifdef CONFIG_OF +static const struct of_device_id tsc2005_of_match[] = { + { .compatible = "ti,tsc2005" }, + { /* sentinel */ } +}; +MODULE_DEVICE_TABLE(of, tsc2005_of_match); +#endif + +static struct spi_driver tsc2005_driver = { + .driver = { + .name = "tsc2005", + .dev_groups = tsc200x_groups, + .of_match_table = of_match_ptr(tsc2005_of_match), + .pm = pm_sleep_ptr(&tsc200x_pm_ops), + }, + .probe = tsc2005_probe, +}; +module_spi_driver(tsc2005_driver); + +MODULE_AUTHOR("Michael Welling "); +MODULE_DESCRIPTION("TSC2005 Touchscreen Driver"); +MODULE_LICENSE("GPL"); +MODULE_ALIAS("spi:tsc2005"); -- cgit v1.3.1
