2021-10-28dt-bindings: dmaengine: bam_dma: Add "powered remotely" modeStephan Gerhold1-0/+2
In some configurations, the BAM DMA controller is set up by a remote processor and the local processor can simply start making use of it without setting up the BAM. This is already supported using the "qcom,controlled-remotely" property. However, for some reason another possible configuration is that the remote processor is responsible for powering up the BAM, but we are still responsible for initializing it (e.g. resetting it etc). Add a "qcom,powered-remotely" property to describe that configuration.

2021-10-27hwmon: (tmp401) Drop support for TMP461Guenter Roeck1-14/+1
TMP461 is almost identical to TMP451, which is already supported by the lm90 driver. At the same time, unlike other sensors from the TMP401 compatible series, it only supports 8-bit temperature read operations, and it supports negative temperatures when configured for its default temperature range, and it supports a temperature offset register. Supporting this chip in the tmp401 driver adds unnecessary complexity. Remove its support from this driver and support the chip with the lm90 driver instead. Fixes: 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations") Reported-by: David T. Wilson <david.wilson@nasa.gov> Cc: David T.

2021-10-27hwmon: (lm90) Add basic support for TI TMP461Guenter Roeck1-0/+10
TMP461 is almost identical to TMP451 and was actually detected as TMP451 with the existing lm90 driver if its I2C address is 0x4c. Add support for it to the lm90 driver. At the same time, improve the chip detection function to at least try to distinguish between TMP451 and TMP461. As a side effect, this fixes commit 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations"). TMP461 does not support word operations on temperature registers, which causes bad temperature readings with the tmp401 driver. The lm90 driver does not perform word operations on temperature registers and thus does not have this problem. Support is listed as basic because TMP461 supports a sensor resolution of 0.0625 degrees C, while the lm90 driver assumes a resolution of 0.125 degrees C. Also, the TMP461 supports negative temperatures with its default temperature range, which is not the case for similar chips supported by the lm90 and the tmp401 drivers. Those limitations will be addressed with follow-up patches. Fixes: 24333ac26d01 ("hwmon: (tmp401) use smb word operations instead of 2 smb byte operations") Reported-by: David T.

2021-10-27leds: add new LED_FUNCTION_PLAYER for player LEDs for game controllers.Roderick Colenbrander1-0/+14
Player LEDs are commonly found on game controllers from Nintendo and Sony to indicate a player ID across a number of LEDs. For example, "Player 2" might be indicated as "-x--" on a device with 4 LEDs where "x" means on. This patch introduces LED_FUNCTION_PLAYER1-5 defines to properly indicate player LEDs from the kernel. Until now there was no good standard, which resulted in inconsistent behavior across xpad, hid-sony, hid-wiimote and other drivers. Moving forward new drivers should use LED_FUNCTION_PLAYERx. Note: management of Player IDs is left to user space, though a kernel driver may pick a default value.

2021-10-26f2fs: introduce fragment allocation mode mount optionDaeho Jeong2-0/+34
Added two options into "mode=" mount option to make it possible for developers to simulate filesystem fragmentation/after-GC situation itself. The developers use these modes to understand filesystem fragmentation/after-GC condition well, and eventually get some insights to handle them better. "fragment:segment": f2fs allocates a new segment in ramdom position. With this, we can simulate the after-GC condition. "fragment:block" : We can scatter block allocation with "max_fragment_chunk" and "max_fragment_hole" sysfs nodes. f2fs will allocate 1..<max_fragment_chunk> blocks in a chunk and make a hole in the length of 1..<max_fragment_hole> by turns in a newly allocated free segment. Plus, this mode implicitly enables "fragment:segment" option for more randomness.

Qualcomm ARM64 DTS additional patches for v5.16 The RPM and RPMh sleep stats are introduced on a number of platforms, to aid the enablement of entering low power mode. The MSM8916 support receives some polishing touches, followed by introduction of the necessary pieces to use the DeviceTree on 32-bit variants of the MSM8916 platform, in particular to boot the secondary CPUs. Based on this support for the Samsung Galaxy S4 Mini Value Edition is introduced. The Asus Zenfone 2 Laser gained touchscreen, sensors and sdcard support. MSM8996 got support for the its crypto hardware and the Xiaomi Mi 5 gained a description of its LCD panel. The Trogdor device on SC7180 gained support for a second source eDP brigde, while SC7280 gains PCIe support and the newly introduced Herobrine device. Both MSM8916 and SDM845 has their standalong SMEM node dropped, in favour of the newly introduced support for specifying the compatible directly on the reserved-memory node. The SM7225 platform is introduced, as a derrivative of SM6350, initial support for the PM6350 PMIC and based on this the Fairphone 4 is introduced. The RB3 and RB5 devices gains msm-id and board-id, to allow the two DTBs to be baked into a single boot.img that can be booted on both devices. As the GDSC driver has been extended to properly describe the relationship between MMCX and MDSS_GDSC, the now deprecated mmcx regulator is removed from SM8250. SM8350 gained CPU topology, idle-states and fastrpc support. FastRPC was also added for SM8150 and the SA8155p ADP got a couple of remoteprocs enabled. Additionally a number of DT validation issues was corrected across the various platforms and devices. * tag 'qcom-arm64-for-5.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (77 commits) Revert "arm64: dts: qcom: msm8916-asus-z00l: Add sensors" arm64: dts: qcom: ipq6018: Remove unused 'iface_clk' property from dma-controller node arm64: dts: qcom: ipq6018: Remove unused 'qcom,config-pipe-trust-reg' property arm64: dts: qcom: sm8350: Add CPU topology and idle-states arm64: dts: qcom: Drop unneeded extra device-specific includes arm64: dts: qcom: msm8916: Drop standalone smem node arm64: dts: qcom: Fix node name of rpm-msg-ram device nodes arm64: dts: qcom: msm8916-asus-z00l: Add sensors arm64: dts: qcom: msm8916-asus-z00l: Add SDCard arm64: dts: qcom: msm8916-asus-z00l: Add touchscreen arm64: dts: qcom: sdm845-oneplus: remove devinfo-size from ramoops node arm64: dts: qcom: sdm845: Fix Qualcomm crypto engine bus clock arm64: dts: qcom: msm8996: Add device tree entries to support crypto engine arm64: dts: qcom: msm8996: move clock-frequency from PN547 NFC to I2C bus arm64: dts: qcom: msm8916-asus-z00l: Add sensors arm64: dts: qcom: sdm630: Add disabled Venus support arm64: dts: qcom: pm660l: Remove board-specific WLED configuration arm64: dts: qcom: Move WLED num-strings from pmi8994 to sony-xperia-tone arm64: dts: qcom: pmi8994: Remove hardcoded linear WLED enabled-strings arm64: dts: qcom: pmi8994: Fix "eternal"->"external" typo in WLED node ...

2021-10-26dt-bindings: watchdog: sunxi: Add compatibles for D1Samuel Holland1-0/+6
D1 keeps the same register layout and clock sources as the R329, but it adds a key field which must be set to update the watchdog's "CFG" and "MODE" registers. Therefore it is not backward-compatible. Similarly to the R329, the D1 has three watchdog instances, and only one of them has the "soft reset" registers. So that instance needs an extra compatible string.

2021-10-26dt-bindings: watchdog: sunxi: Add compatibles for R329Samuel Holland1-1/+41
On existing SoCs, the watchdog has a single clock input: HOSC (OSC24M) divided by 750. However, starting with R329, LOSC (OSC32k) is added as an alternative clock source, with a bit to switch between them. Since 24 MHz / 750 == 32 kHz, not 32.768 kHz, the hardware adjusts the cycle counts to keep the timeouts independent of the clock source. This keeps the programming interface backward-compatible. Furthermore, the R329 has two watchdogs: one for use by the ARM CPUs at 0x20000a0, and a second one for use by the DSPs at 0x7020400. The first of these adds two more new registers, to allow software to immediately assert the SoC reset signal. Add an additional "-reset" suffix to signify the presence of this feature.
