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 ... --- Documentation/ABI/testing/sysfs-class-rtc | 91 +++++++++++++++++++++++++++++++ 1 file changed, 91 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-class-rtc (limited to 'Documentation/ABI/testing/sysfs-class-rtc') diff --git a/Documentation/ABI/testing/sysfs-class-rtc b/Documentation/ABI/testing/sysfs-class-rtc new file mode 100644 index 000000000..95984289a --- /dev/null +++ b/Documentation/ABI/testing/sysfs-class-rtc @@ -0,0 +1,91 @@ +What: /sys/class/rtc/ +Date: March 2006 +KernelVersion: 2.6.17 +Contact: linux-rtc@vger.kernel.org +Description: + The rtc/ class subdirectory belongs to the RTC subsystem. + +What: /sys/class/rtc/rtcX/ +Date: March 2006 +KernelVersion: 2.6.17 +Contact: linux-rtc@vger.kernel.org +Description: + The /sys/class/rtc/rtc{0,1,2,3,...} directories correspond + to each RTC device. + +What: /sys/class/rtc/rtcX/date +Date: March 2006 +KernelVersion: 2.6.17 +Contact: linux-rtc@vger.kernel.org +Description: + (RO) RTC-provided date in YYYY-MM-DD format + +What: /sys/class/rtc/rtcX/hctosys +Date: September 2009 +KernelVersion: 2.6.32 +Contact: linux-rtc@vger.kernel.org +Description: + (RO) 1 if the RTC provided the system time at boot via the + CONFIG_RTC_HCTOSYS kernel option, 0 otherwise + +What: /sys/class/rtc/rtcX/max_user_freq +Date: October 2007 +KernelVersion: 2.6.24 +Contact: linux-rtc@vger.kernel.org +Description: + (RW) The maximum interrupt rate an unprivileged user may request + from this RTC. + +What: /sys/class/rtc/rtcX/name +Date: March 2006 +KernelVersion: 2.6.17 +Contact: linux-rtc@vger.kernel.org +Description: + (RO) The name of the RTC corresponding to this sysfs directory + +What: /sys/class/rtc/rtcX/range +Date: January 2018 +KernelVersion: 4.16 +Contact: linux-rtc@vger.kernel.org +Description: + Valid time range for the RTC, as seconds from epoch, formatted + as [min, max] + +What: /sys/class/rtc/rtcX/since_epoch +Date: March 2006 +KernelVersion: 2.6.17 +Contact: linux-rtc@vger.kernel.org +Description: + (RO) RTC-provided time as the number of seconds since the epoch + +What: /sys/class/rtc/rtcX/time +Date: March 2006 +KernelVersion: 2.6.17 +Contact: linux-rtc@vger.kernel.org +Description: + (RO) RTC-provided time in 24-hour notation (hh:mm:ss) + +What: /sys/class/rtc/rtcX/offset +Date: February 2016 +KernelVersion: 4.6 +Contact: linux-rtc@vger.kernel.org +Description: + (RW) The amount which the rtc clock has been adjusted in + firmware.
