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 ... --- sound/firewire/cmp.h | 52 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 sound/firewire/cmp.h (limited to 'sound/firewire/cmp.h') diff --git a/sound/firewire/cmp.h b/sound/firewire/cmp.h new file mode 100644 index 000000000..66fc08b74 --- /dev/null +++ b/sound/firewire/cmp.h @@ -0,0 +1,52 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef SOUND_FIREWIRE_CMP_H_INCLUDED +#define SOUND_FIREWIRE_CMP_H_INCLUDED + +#include +#include +#include "iso-resources.h" + +struct fw_unit; + +enum cmp_direction { + CMP_INPUT = 0, + CMP_OUTPUT, +}; + +/** + * struct cmp_connection - manages an isochronous connection to a device + * @speed: the connection's actual speed + * + * This structure manages (using CMP) an isochronous stream between the local + * computer and a device's input plug (iPCR) and output plug (oPCR). + * + * There is no corresponding oPCR created on the local computer, so it is not + * possible to overlay connections on top of this one. + */ +struct cmp_connection { + int speed; + /* private: */ + bool connected; + struct mutex mutex; + struct fw_iso_resources resources; + __be32 last_pcr_value; + unsigned int pcr_index; + unsigned int max_speed; + enum cmp_direction direction; +}; + +int cmp_connection_init(struct cmp_connection *connection, + struct fw_unit *unit, + enum cmp_direction direction, + unsigned int pcr_index); +int cmp_connection_check_used(struct cmp_connection *connection, bool *used); +void cmp_connection_destroy(struct cmp_connection *connection); + +int cmp_connection_reserve(struct cmp_connection *connection, + unsigned int max_payload); +void cmp_connection_release(struct cmp_connection *connection); + +int cmp_connection_establish(struct cmp_connection *connection); +void cmp_connection_break(struct cmp_connection *connection); + +#endif -- cgit v1.3.1
