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 ... --- arch/microblaze/lib/modsi3.S | 74 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 74 insertions(+) create mode 100644 arch/microblaze/lib/modsi3.S (limited to 'arch/microblaze/lib/modsi3.S') diff --git a/arch/microblaze/lib/modsi3.S b/arch/microblaze/lib/modsi3.S new file mode 100644 index 000000000..64154865c --- /dev/null +++ b/arch/microblaze/lib/modsi3.S @@ -0,0 +1,74 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#include + +/* +* modulo operation for 32 bit integers. +* Input : op1 in Reg r5 +* op2 in Reg r6 +* Output: op1 mod op2 in Reg r3 +*/ + + .text + .globl __modsi3 + .type __modsi3, @function + .ent __modsi3 + +__modsi3: + .frame r1, 0, r15 + + addik r1, r1, -16 + swi r28, r1, 0 + swi r29, r1, 4 + swi r30, r1, 8 + swi r31, r1, 12 + + beqi r6, div_by_zero /* div_by_zero division error */ + beqi r5, result_is_zero /* result is zero */ + bgeid r5, r5_pos + /* get the sign of the result [ depends only on the first arg] */ + add r28, r5, r0 + rsubi r5, r5, 0 /* make r5 positive */ +r5_pos: + bgei r6, r6_pos + rsubi r6, r6, 0 /* make r6 positive */ +r6_pos: + addik r3, r0, 0 /* clear mod */ + addik r30, r0, 0 /* clear div */ + addik r29, r0, 32 /* initialize the loop count */ +/* first part try to find the first '1' in the r5 */ +div1: + add r5, r5, r5 /* left shift logical r5 */ + bgeid r5, div1 + addik r29, r29, -1 +div2: + /* left shift logical r5 get the '1' into the carry */ + add r5, r5, r5 + addc r3, r3, r3 /* move that bit into the mod register */ + rsub r31, r6, r3 /* try to subtract (r30 a r6) */ + blti r31, mod_too_small + /* move the r31 to mod since the result was positive */ + or r3, r0, r31 + addik r30, r30, 1 +mod_too_small: + addik r29, r29, -1 + beqi r29, loop_end + add r30, r30, r30 /* shift in the '1' into div */ + bri div2 /* div2 */ +loop_end: + bgei r28, return_here + brid return_here + rsubi r3, r3, 0 /* negate the result */ +div_by_zero: +result_is_zero: + or r3, r0, r0 /* set result to 0 [both mod as well as div are 0] */ +return_here: +/* restore values of csrs and that of r3 and the divisor and the dividend */ + lwi r28, r1, 0 + lwi r29, r1, 4 + lwi r30, r1, 8 + lwi r31, r1, 12 + rtsd r15, 8 + addik r1, r1, 16 + +.size __modsi3, . - __modsi3 +.end __modsi3 -- cgit v1.3.1
