2020-03-08hwmon: (k10temp) Swap Tdie and Tctl on Family 17h CPUsGuenter Roeck
Traditionally, the temperature displayed by k10temp was Tctl. On Family 17h CPUs, Tdie was displayed instead. To reduce confusion, Tctl was added later as second temperature. This resulted in Tdie being reported as temp1_input, and Tctl as temp2_input. This is different to non-Ryzen CPUs, where Tctl is displayed as temp1_input. Swap temp1_input and temp2_input on Family 17h CPUs, such that Tctl is now reported as temp1_input and Tdie is reported as temp2_input, to align with other CPUs, streamline the code, and make it less confusing. Coincidentally, this also aligns the code with its documentation, which states that Tdie is reported as temp2_input. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2020-03-08hwmon: Support ADI Fan Control IPNuno Sá
The purpose of this IP Core is to control the fan used for the cooling of a Xilinx Zynq Ultrascale+ MPSoC without the need of any external temperature sensors. To achieve this, the IP core uses the PL SYSMONE4 primitive to obtain the PL temperature and, based on those readings, it then outputs a PWM signal to control the fan rotation accordingly.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Olof Johansson: "We've been accruing these for a couple of weeks, so the batch is a bit bigger than usual. Largest delta is due to a led-bl driver that is added -- there was a miscommunication before the merge window and the driver didn't make it in. Due to this, the platforms needing it regressed. At this point, it seemed easier to add the new driver than unwind the changes. Besides that, there are a handful of various fixes: - AMD tee memory leak fix - A handful of fixlets for i.MX SCU communication - A few maintainers woke up and realized DEBUG_FS had been missing for a while, so a few updates of that. ... and the usual collection of smaller fixes to various platforms" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (37 commits) ARM: socfpga_defconfig: Add back DEBUG_FS arm64: dts: socfpga: agilex: Fix gmac compatible ARM: bcm2835_defconfig: Explicitly restore CONFIG_DEBUG_FS arm64: dts: meson: fix gxm-khadas-vim2 wifi arm64: dts: meson-sm1-sei610: add missing interrupt-names ARM: meson: Drop unneeded select of COMMON_CLK ARM: dts: bcm2711: Add pcie0 alias ARM: dts: bcm283x: Add missing properties to the PWR LED tee: amdtee: fix memory leak in amdtee_open_session() ARM: OMAP2+: Fix compile if CONFIG_HAVE_ARM_SMCCC is not set arm: dts: dra76x: Fix mmc3 max-frequency ARM: dts: dra7: Add "dma-ranges" property to PCIe RC DT nodes bus: ti-sysc: Fix 1-wire reset quirk ARM: dts: r8a7779: Remove deprecated "renesas, rcar-sata" compatible value soc: imx-scu: Align imx sc msg structs to 4 firmware: imx: Align imx_sc_msg_req_cpu_start to 4 firmware: imx: scu-pd: Align imx sc msg structs to 4 firmware: imx: misc: Align imx sc msg structs to 4 firmware: imx: scu: Ensure sequential TX ARM: dts: imx7-colibri: Fix frequency for sd/mmc ...

For the predisable hook, the disable code should occur before detaching the poll func, and for the postenable hook, the poll func should be attached before the enable code.

This change adds the detaching of the poll function, and moves/renames lmp91000_buffer_preenable() function to lmp91000_buffer_postenable(). The idea is to make it more symmetrical, so that when the iio_triggered_buffer_{predisable,postenable} functions get removed, it's easier to see.

2020-03-08iio: industrialio-core: Fix debugfs readAlexandru Tachici
Currently iio_debugfs_read_reg calls debugfs_reg_access every time it is ran. Reading the same hardware register multiple times during the same reading of a debugfs file can cause unintended effects. For example for each: cat iio:device0/direct_reg_access the file_operations.read function will be called at least twice. First will return the full length of the string in bytes and the second will return 0. This patch makes iio_debugfs_read_reg to call debugfs_reg_access only when the user's buffer position (*ppos) is 0. (meaning it is the beginning of a new reading of the debugfs file).

Then, introduce 'clk_enabled' flag, instead of relying on CR1 EN bit, to keep track of clock being enabled (balanced refcount). Propagate this anywhere else in the driver. Also add 'remove' routine to stop timer and disable clock in case it has been left enabled. Enforce the user interface has been unregistered in the remove routine, before disabling the hardware to avoid possible race.
