[PATCH 6.1.y] spi: microchip-core: ensure TX and RX FIFOs are empty at start of a transfer

by jianqi.ren.cn＠windriver.com

From: Steve Wilkins <steve.wilkins(a)raymarine.com> [ Upstream commit 9cf71eb0faef4bff01df4264841b8465382d7927 ] While transmitting with rx_len == 0, the RX FIFO is not going to be emptied in the interrupt handler. A subsequent transfer could then read crap from the previous transfer out of the RX FIFO into the start RX buffer. The core provides a register that will empty the RX and TX FIFOs, so do that before each transfer.

[PATCH] arm64: dts: rockchip: Fix broken tsadc pinctrl binding for rk3588

There is no pinctrl "gpio" and "otpout" (probably designed as "output") handling in the tsadc driver. Let's use proper binding "default" and "sleep".

S/PDIF not detected anymore / regression on recent kernel 6.7 ?

by Serge SIMON

Dear Kernel maintainers, I think i'm encountering (for the first time in years !) a regression with the "6.7.arch3-1" kernel (whereas no issues with "6.6.10.arch1-1", on which i reverted). I'm running a (up-to-date, and non-LTS) ARCHLINUX desktop, on a ASUS B560-I motherboard, with 3 monitors (attached to a 4-HDMI outputs card), plus an audio S/PDIF optic output at motherboard level. With the latest kernel, the S/PIDF optic output of the motherboard is NOT detected anymore (and i haven't been able to see / find anything in the logs at quick glance, neither journalctl -xe nor dmesg). Once reverted to 6.6.10, everything is fine again. For example, in a working situation (6.6.10), i have : cat /proc/asound/pcm 00-00: ALC1220 Analog : ALC1220 Analog : playback 1 : capture 1 00-01: ALC1220 Digital : ALC1220 Digital : playback 1 00-02: ALC1220 Alt Analog : ALC1220 Alt Analog : capture 1 01-03: HDMI 0 : HDMI 0 : playback 1 01-07: HDMI 1 : HDMI 1 : playback 1 01-08: HDMI 2 : HDMI 2 : playback 1 01-09: HDMI 3 : HDMI 3 : playback 1 Whereas while on the latest 6.7 kernel, i only had the 4 HDMI lines (linked to a NVIDIA T600 card, with 4 HDMI outputs) and not the three first ones (attached to the motherboard). (of course i did several tests with 6.7, reboot, ... without any changes) Any idea ? Best regards -- Serge.

[PATCH] asm-generic/io.h: Skip trace helpers if rwmmio events are disabled

by Varad Gautam

With `CONFIG_TRACE_MMIO_ACCESS=y`, the `{read,write}{b,w,l,q}{_relaxed}()` mmio accessors unconditionally call `log_{post_}{read,write}_mmio()` helpers, which in turn call the ftrace ops for `rwmmio` trace events This adds a performance penalty per mmio accessor call, even when `rwmmio` events are disabled at runtime (~80% overhead on local measurement). Guard these with `tracepoint_enabled()`.
