2023-02-13wifi: rtw88: Move enum rtw_tx_queue_type mapping code to tx.{c,h}Martin Blumenstingl
This code is not specific to the PCIe bus type but can be re-used by USB and SDIO bus types. Move it to tx.{c,h} to avoid code-duplication in the future. While here, add checking of the ac argument in rtw_tx_ac_to_hwq() so we're not accessing entries beyond the end of the array.

2023-02-13wifi: libertas: add support for WPS enrollee IE in probe requestsDoug Brown
Add compatibility with WPS by passing on WPS enrollee information in probe requests. Ignore other IEs supplied in the scan request. This also has the added benefit of restoring compatibility with newer wpa_supplicant versions that always add scan IEs. Previously, with max_scan_ie_len set to 0, scans would always fail.

2023-02-13wifi: libertas: only add RSN/WPA IE in lbs_add_wpa_tlvDoug Brown
The existing code only converts the first IE to a TLV, but it returns a value that takes the length of all IEs into account. When there is more than one IE (which happens with modern wpa_supplicant versions for example), the returned length is too long and extra junk TLVs get sent to the firmware, resulting in an association failure. Fix this by finding the first RSN or WPA IE and only adding that. This has the extra benefit of working properly if the RSN/WPA IE isn't the first one in the IE buffer. While we're at it, clean up the code to use the available structs like the other lbs_add_* functions instead of directly manipulating the TLV buffer.

New support for a couple of USB modem sticks from THWC are introduced, so is support for Xiaomi Mi Pad 5 Pro and the Pro SKU of the Herobrine device. The Core Bus Fabric (CBF) is introduced on MSM8996. Interconnect paths for UFS are also described. A few fixes related to the power-grid of herobrine, on SC7280, are introduced. QFPROM is introduced on IPQ8074 and Interconnect providers are added for SDM670. On SDM845 the duplicated wcd9340 audio coded description is moved from devices to a common file, audio devices are added to the OnePlus 6 and 6T. On SM6115 debug UART, SMP2P, watchdog nodes are introduced, and the platform is switched to use #address/size-cells of 2, in line with most other platforms. Camera control interface and clock controllers are added for SM6350, and the CCI interface is enabled on the Fairphone FP4. On SM8350 the interconnect reference of SDHCI controller is corrected, DSI1 PHY clocks are properly described as sources for the Display clock controller and DSI1 is wired up to the display controller. The firmware paths are corrected for the Sony Xperia Nagara platform. The GPR bus, audio servic3es and LPASS pinctrl nodes are added for the SM8550 platform. Additionally a few small typos/errors are corrected. gpio-ranges are corrected across MSM8953, SM6115 and SC8280XP and a range of DT validation issues are corrected. * tag 'qcom-arm64-for-6.3-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (81 commits) arm64: dts: qcom: sc7280: Power herobrine's 3.3 eDP/TS rail more properly arm64: dts: qcom: pmk8550: fix PON compatible arm64: dts: qcom: sm8550: fix DSI controller compatible arm64: dts: qcom: sc7280: Hook up the touchscreen IO rail on evoker arm64: dts: qcom: sc7280: Hook up the touchscreen IO rail on villager arm64: dts: qcom: sc7280: Add 3ms ramp to herobrine's pp3300_left_in_mlb arm64: dts: qcom: sc7280: On QCard, regulator L3C should be 1.8V arm64: dts: qcom: sc8280xp: correct LPASS GPIO gpio-ranges arm64: dts: qcom: msm8992-lg-bullhead: Enable regulators arm64: dts: qcom: sm6115: correct TLMM gpio-ranges arm64: dts: qcom: msm8953: correct TLMM gpio-ranges arm64: dts: qcom: msm8992-lg-bullhead: Correct memory overlaps with the SMEM and MPSS memory regions arm64: dts: qcom: sm8350-hdk: correct LT9611 pin function arm64: dts: qcom: sm8350-hdk: align pin config node names with bindings arm64: dts: qcom: sm6350: Use specific qmpphy compatible arm64: dts: qcom: sm6115: Add smp2p nodes arm64: dts: qcom: sm7225-fairphone-fp4: Enable CCI busses arm64: dts: qcom: sm6350: Add CCI nodes arm64: dts: qcom: sm6350: Add camera clock controller dt-bindings: clock: add QCOM SM6350 camera clock bindings ...

2023-02-13clocksource/drivers/riscv: Get rid of clocksource_arch_init() callbackLad Prabhakar
Having a clocksource_arch_init() callback always sets vdso_clock_mode to VDSO_CLOCKMODE_ARCHTIMER if GENERIC_GETTIMEOFDAY is enabled, this is required for the riscv-timer. This works for platforms where just riscv-timer clocksource is present. On platforms where other clock sources are available we want them to register with vdso_clock_mode set to VDSO_CLOCKMODE_NONE. On the Renesas RZ/Five SoC OSTM block can be used as clocksource [0], to avoid multiple clock sources being registered as VDSO_CLOCKMODE_ARCHTIMER move setting of vdso_clock_mode in the riscv-timer driver instead of doing this in clocksource_arch_init() callback as done similarly for ARM/64 architecture.

2023-02-13clocksource/drivers/sh_cmt: Mark driver as non-removableUwe Kleine-König
The comment in the remove callback suggests that the driver is not supposed to be unbound. However returning an error code in the remove callback doesn't accomplish that. Instead set the suppress_bind_attrs property (which makes it impossible to unbind the driver via sysfs). The only remaining way to unbind a sh_cmt device would be module unloading, but that doesn't apply here, as the driver cannot be built as a module. Also drop the useless remove callback.

2023-02-13clocksource/drivers/riscv: Increase the clock source ratingSamuel Holland
RISC-V provides an architectural clock source via the time CSR. This clock source exposes a 64-bit counter synchronized across all CPUs. Because it is accessed using a CSR, it is much more efficient to read than MMIO clock sources. For example, on the Allwinner D1, reading the sun4i timer in a loop takes 131 cycles/iteration, while reading the RISC-V time CSR takes only 5 cycles/iteration. Adjust the RISC-V clock source rating so it is preferred over the various platform-specific MMIO clock sources.

2023-02-13RISC-V: time: initialize hrtimer based broadcast clock event deviceConor Dooley
Similarly to commit 022eb8ae8b5e ("ARM: 8938/1: kernel: initialize broadcast hrtimer based clock event device"), RISC-V needs to initiate hrtimer based broadcast clock event device before C3STOP can be used. Otherwise, the introduction of C3STOP for the RISC-V arch timer in commit 232ccac1bd9b ("clocksource/drivers/riscv: Events are stopped during CPU suspend") leaves us without any broadcast timer registered. This prevents the kernel from entering oneshot mode, which breaks timer behaviour, for example clock_nanosleep(). A test app that sleeps each cpu for 6, 5, 4, 3 ms respectively, HZ=250 & C3STOP enabled, the sleep times are rounded up to the next jiffy: == CPU: 1 == == CPU: 2 == == CPU: 3 == == CPU: 4 == Mean: 7.974992 Mean: 7.976534 Mean: 7.962591 Mean: 3.952179 Std Dev: 0.154374 Std Dev: 0.156082 Std Dev: 0.171018 Std Dev: 0.076193 Hi: 9.472000 Hi: 10.495000 Hi: 8.864000 Hi: 4.736000 Lo: 6.087000 Lo: 6.380000 Lo: 4.872000 Lo: 3.403000 Samples: 521 Samples: 521 Samples: 521 Samples: 521 Link: https://lore.kernel.org/linux-riscv/YzYTNQRxLr7Q9JR0@spud/ Fixes: 232ccac1bd9b ("clocksource/drivers/riscv: Events are stopped during CPU suspend") Suggested-by: Samuel Holland <samuel@sholland.org> Signed-off-by: Conor Dooley <conor.dooley@microchip.com> Signed-off-by: Anup Patel <apatel@ventanamicro.com> Reviewed-by: Samuel Holland <samuel@sholland.org> Acked-by: Palmer Dabbelt <palmer@rivosinc.com> Link: https://lore.kernel.org/r/20230103141102.772228-2-apatel@ventanamicro.com Signed-off-by: Daniel Lezcano <daniel.lezcano@kernel.org>

Current phy_ethtool_get/set_eee() implementation is great and it is possible to make it even better: - this functionality is for devices implementing parts of IEEE 802.3 specification beyond Clause 22. The better place for this code is phy-c45.c - currently it is able to do read/write operations on PHYs with different abilities to not existing registers. It is better to use stored supported_eee abilities to avoid false read/write operations. - the eee_active detection will provide wrong results on not supported link modes. It is better to validate speed/duplex properties against supported EEE link modes. - it is able to support only limited amount of link modes. We have more EEE link modes...
