Randconfig builds show another broken dependency: WARNING: unmet direct dependencies detected for PHY_MTK_MIPI_DSI Depends on [n]: ARCH_MEDIATEK [=n] && OF [=y] Selected by [m]: - DRM_MEDIATEK [=m] && HAS_IOMEM [=y] && DRM [=m] && (ARCH_MEDIATEK [=n] || ARM [=y] && COMPILE_TEST [=y]) && COMMON_CLK [=y] && HAVE_ARM_SMCCC [=y] && OF [=y] && MTK_MMSYS [=y] This is similar to the hdmi driver I fixed earlier, and I guess the common-clk bug would sooner or later also manifest here, so just use the exact same solution I chose for the other driver, and hope that any future drivers just copy it from here.

2021-01-04lib/raid6: Let $(UNROLL) rules work with macOS userlandJohn Millikin
Older versions of BSD awk are fussy about the order of '-v' and '-f' flags, and require a space after the flag name. This causes build failures on platforms with an old awk, such as macOS and NetBSD. Since GNU awk and modern versions of BSD awk (distributed with FreeBSD/OpenBSD) are fine with either form, the definition of 'cmd_unroll' can be trivially tweaked to let the lib/raid6 Makefile work with both old and new awk flag dialects.

2021-01-04kconfig: Support building mconf with vendor sysroot ncursesJohn Millikin
Changes the final fallback path in the ncurses locator for mconf to support host compilers with a non-default sysroot. This is similar to the hardcoded search for ncurses under '/usr/include', but can support compilers that keep their default header and library directories elsewhere. For nconfig, do nothing because the only vendor compiler I'm aware of with this layout (Apple Clang) ships an ncurses version that's too old for nconfig anyway.

2021-01-03arm64: dts: qcom: c630: keep both touchpad devices enabledShawn Guo
Indicated by AML code in ACPI table, the touchpad in-use could be found on two possible slave addresses on &i2c3, i.e. hid@15 and hid@2c. And which one is in-use can be determined by reading another address on the I2C bus. Unfortunately, for DT boot, there is currently no support in firmware to make this check and patch DT accordingly. This results in a non-functional touchpad on those C630 devices with hid@2c. As i2c-hid driver will stop probing the device if there is nothing on the slave address, we can actually keep both devices enabled in DT, and i2c-hid driver will only probe the existing one. The only problem is that we cannot set up pinctrl in both device nodes, as two devices with the same pinctrl will cause pin conflict that makes the second device fail to probe. Let's move the pinctrl state up to parent node to solve this problem. As the pinctrl state of parent node is already defined in sdm845.dtsi, it ends up with overwriting pinctrl-0 with i2c3_hid_active state added in there.

2021-01-03crypto: arm/chacha-neon - add missing counter incrementArd Biesheuvel
Commit 86cd97ec4b943af3 ("crypto: arm/chacha-neon - optimize for non-block size multiples") refactored the chacha block handling in the glue code in a way that may result in the counter increment to be omitted when calling chacha_block_xor_neon() to process a full block. This violates the skcipher API, which requires that the output IV is suitable for handling more input as long as the preceding input has been presented in round multiples of the block size. Also, the same code is exposed via the chacha library interface whose callers may actually rely on this increment to occur even for final blocks that are smaller than the chacha block size. So increment the counter after calling chacha_block_xor_neon().

2021-01-01Input: st1232 - wait until device is ready before reading resolutionGeert Uytterhoeven
According to the st1232 datasheet, the host has to wait for the device to change into Normal state before accessing registers other than the Status Register. If the reset GPIO is wired, the device is powered on during driver probe, just before reading the resolution. However, the latter may happen before the device is ready, leading to a probe failure: st1232-ts 1-0055: Failed to read resolution: -6 Fix this by waiting until the device is ready, by trying to read the Status Register until it indicates so, or until timeout. On Armadillo 800 EVA, typically the first read fails with an I2C transfer error, while the second read indicates the device is ready.

2020-12-31docs: Fix reST markup when linking to sectionsNícolas F. R. A. Prado
During the process of converting the documentation to reST, some links were converted using the following wrong syntax (and sometimes using %20 instead of spaces): `Display text <#section-name-in-html>`__ This syntax isn't valid according to the docutils' spec [1], but more importantly, it is specific to HTML, since it uses '#' to link to an HTML anchor. The right syntax would instead use a docutils hyperlink reference as the embedded URI to point to the section [2], that is: `Display text <Section Name_>`__ This syntax works in both HTML and PDF. The LaTeX toolchain doesn't mind the HTML anchor syntax when generating the pdf documentation (make pdfdocs), that is, the build succeeds but the links don't work, but that syntax causes errors when trying to build using the not-yet-merged rst2pdf: ValueError: format not resolved, probably missing URL scheme or undefined destination target for 'Forcing%20Quiescent%20States' So, use the correct syntax in order to have it work in all different output formats.

2020-12-31efi/apple-properties: Reinstate support for boolean propertiesLukas Wunner
Since commit 4466bf82821b ("efi/apple-properties: use PROPERTY_ENTRY_U8_ARRAY_LEN"), my MacBook Pro issues a -ENODATA error when trying to assign EFI properties to the discrete GPU: pci 0000:01:00.0: assigning 56 device properties pci 0000:01:00.0: error -61 assigning properties That's because some of the properties have no value. They're booleans whose presence can be checked by drivers, e.g. "use-backlight-blanking". Commit 6e98503dba64 ("efi/apple-properties: Remove redundant attribute initialization from unmarshal_key_value_pairs()") employed a trick to store such booleans as u8 arrays (which is the data type used for all other EFI properties on Macs): It cleared the property_entry's "is_array" flag, thereby denoting that the value is stored inline in the property_entry. Commit 4466bf82821b erroneously removed that trick. It was probably a little fragile to begin with. Reinstate support for boolean properties by explicitly invoking the PROPERTY_ENTRY_BOOL() initializer for properties with zero-length value.

2020-12-30kernel/io_uring: cancel io_uring before task worksPavel Begunkov
For cancelling io_uring requests it needs either to be able to run currently enqueued task_works or having it shut down by that moment. Otherwise io_uring_cancel_files() may be waiting for requests that won't ever complete. Go with the first way and do cancellations before setting PF_EXITING and so before putting the task_work infrastructure into a transition state where task_work_run() would better not be called.

2020-12-30intel_idle: add SnowRidge C-state tableArtem Bityutskiy
Add C-state table for the SnowRidge SoC which is found on Intel Jacobsville platforms. The following has been changed. 1. C1E latency changed from 10us to 15us. It was measured using the open source "wult" tool (the "nic" method, 15us is the 99.99th percentile). 2. C1E power break even changed from 20us to 25us, which may result in less C1E residency in some workloads. 3. C6 latency changed from 50us to 130us. Measured the same way as C1E. The C6 C-state is supported only by some SnowRidge revisions, so add a C-state table commentary about this. On SnowRidge, C6 support is enumerated via the usual mechanism: "mwait" leaf of the "cpuid" instruction. The 'intel_idle' driver does check this leaf, so even though C6 is present in the table, the driver will only use it if the CPU does support it.

2020-12-30cpufreq: intel_pstate: Fix fast-switch fallback pathRafael J. Wysocki
When sugov_update_single_perf() falls back to the "frequency" path due to the missing scale-invariance, it will call cpufreq_driver_fast_switch() via sugov_fast_switch() and the driver's ->fast_switch() callback will be invoked, so it must not be NULL. However, after commit a365ab6b9dfb ("cpufreq: intel_pstate: Implement the ->adjust_perf() callback") intel_pstate sets ->fast_switch() to NULL when it is going to use intel_cpufreq_adjust_perf(), which is a mistake, because on x86 the scale-invariance may be turned off dynamically, so modify it to retain the original ->adjust_perf() callback pointer.
