2022-07-21spi: spi-rspi: Fix PIO fallback on RZ platformsBiju Das
RSPI IP on RZ/{A, G2L} SoC's has the same signal for both interrupt and DMA transfer request. Setting DMARS register for DMA transfer makes the signal to work as a DMA transfer request signal and subsequent interrupt requests to the interrupt controller are masked. PIO fallback does not work as interrupt signal is disabled. This patch fixes this issue by re-enabling the interrupts by calling dmaengine_synchronize().

2022-07-21ACPI: resource: skip IRQ override on AMD Zen platformsChuanhong Guo
IRQ override isn't needed on modern AMD Zen systems. There's an active low keyboard IRQ on AMD Ryzen 6000 and it will stay this way on newer platforms. This IRQ override breaks keyboards for almost all Ryzen 6000 laptops currently on the market. Skip this IRQ override for all AMD Zen platforms because this IRQ override is supposed to be a workaround for buggy ACPI DSDT and we can't have a long list of all future AMD CPUs/Laptops in the kernel code. If a device with buggy ACPI DSDT shows up, a separated list containing just them should be created.

2022-07-21hwmon: (tps23861) fix byte order in current and voltage registersAlexandru Gagniuc
Trying to use this driver on a big-endian machine results in garbage values for voltage and current. The tps23861 registers are little- endian, and regmap_read_bulk() does not do byte order conversion. Thus on BE machines, the most significant bytes got modified, and were trimmed by the VOLTAGE_CURRENT_MASK. To resolve this use uint16_t values, and convert them to host byte order using le16_to_cpu(). This results in correct readings on MIPS.

2022-07-21hwmon: (aspeed-pwm-tacho) increase fan tach period (again)Paul Fertser
The old value allows measuring fan speeds down to about 970 RPM and gives timeout for anything less than that. It is problematic because it can also be used as an indicator for fan failure or absence. Despite having read the relevant section of "ASPEED AST2500/AST2520 A2 Datasheet – V1.7" multiple times I wasn't able to figure out what exactly "fan tach period" and "fan tach falling point of period" mean (both are set by the driver from the constant this patch is amending). Experimentation with a Tioga Pass OCP board (AST2500 BMC) showed that value of 0x0108 gives time outs for speeds below 1500 RPM and the value offered by the patch is good for at least 750 RPM (the fans can't spin any slower so the lower bound is unknown). Measuring with the fans spinning takes about 30 ms, sometimes down to 18 ms, so about the same as with the previous value. This constant was last changed with commit 762b1e888013 ("hwmon: (aspeed-pwm-tacho) increase fan tach period") Signed-off-by: Paul Fertser <fercerpav@gmail.com> Link: https://lore.kernel.org/r/20220714142344.27071-1-fercerpav@gmail.com Signed-off-by: Guenter Roeck <linux@roeck-us.net>

This commit adds a timer which is reset every time a new prox event is received. When the timer expires we check to see if the pen is still in prox and force it out if necessary.

2022-07-20drm/amd/display: fix trigger_hotplug to support mst caseWayne Lin
[Why & How] Correct few problems below to have debugfs trigger_hotplug entry supports mst case * Adjust the place for acquiring the hpd_lock. We'll also access dc_link when simulate unplug * When detect the connector is a mst root, call reset_cur_dp_mst_topology() to simulate unplug * Don't support hotplug caused by CSN message since we can't change mst topology info directly. We can't simulate that * Clean up redundant code Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Reviewed-by: Hersen Wu <hersenxs.wu@amd.com> Acked-by: Alan Liu <HaoPing.Liu@amd.com> Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-07-20drm/amd/display: Support vertical interrupt 0 for all dcn ASICWayne Lin
[Why] When CONFIG_DRM_AMD_SECURE_DISPLAY is enabled, it will try to register vertical interrupt 0 for specific task. Currently, only dcn10 have defined relevant info for vertical interrupt 0. If we enable CONFIG_DRM_AMD_SECURE_DISPLAY for other dcn ASIC, will get DC_IRQ_SOURCE_INVALID while calling dc_interrupt_to_irq_source() and cause pointer errors. [How] Add support of vertical interrupt 0 for all dcn ASIC.
