2020-11-12pinctrl: jasperlake: Unhide SPI group of pinsAndy Shevchenko
If the group of pins is hidden in the pin list it affects the register offset calculation despite fixed GPIO base. Hence, the offsets of all pins after the hidden group are broken. Instead we have to unhide the group and use a flag to exclude it from GPIO number space.

2020-11-10pinctrl: qcom: Kconfig: Rework PINCTRL_MSM to be a depenency rather then a ↵John Stultz
selected config This patch reworks PINCTRL_MSM to be a visible option, and instead of having the various SoC specific drivers select PINCTRL_MSM, this switches those configs to depend on PINCTRL_MSM. This is useful, as it will be needed in order to cleanly support having the qcom-scm driver, which pinctrl-msm calls into, configured as a module. Without this change, we would eventually have to add dependency lines to every config that selects PINCTRL_MSM, and that would becomes a maintenance headache. We also add PINCTRL_MSM to the arm64 defconfig to avoid surprises as otherwise PINCTRL_MSM/IPQ* options previously enabled, will be off.

Add the "lcd-8bit" group to the "lcd" function. As "lcd-24bit" is a superset of "lcd-8bit", in theory the former could be modified to only contain the pins not already included in "lcd-8bit", just like how it's done for the JZ4740 and JZ4725B platforms. However, we can't do that without breaking Device Tree ABI, so in that case we have no choice but to have two groups containing the same pins.

2020-11-10pinctrl: ingenic: Get rid of repetitive dataPaul Cercueil
Abuse the pin function pointer to store the pin function value directly, when all the pins of a group have the same function value. Now when the pointer value is <= 3 (unsigned), the pointer value is used as the pin function; otherwise it is used as a regular pointer. This drastically reduces the number of pin function tables needed, and drops .data usage by about 2 KiB. Additionally, the few pin function tables that are still around now contain u8 instead of int, since the largest number that will be stored is 3.

2020-10-26pinctrl: intel: Set default bias in case no particular value givenAndy Shevchenko
When GPIO library asks pin control to set the bias, it doesn't pass any value of it and argument is considered boolean (and this is true for ACPI GpioIo() / GpioInt() resources, by the way). Thus, individual drivers must behave well, when they got the resistance value of 1 Ohm, i.e. transforming it to sane default. In case of Intel pin control hardware the 5 kOhm sounds plausible because on one hand it's a minimum of resistors present in all hardware generations and at the same time it's high enough to minimize leakage current (will be only 200 uA with the above choice).

Hence, additional values can be: 011 ~833.3 Ohm 101 ~952.4 Ohm 110 ~4 kOhm 111 ~800 Ohm That said, convert TERM definitions to be the bit masks to reflect the above.

To provide backward compatibility with existing userspace we introduce parisc specific wrappers for those syscalls which filter out the old O_NONBLOCK value and replaces it with the new one. - Prevent HIL bus driver to get stuck when keyboard or mouse isn't attached - Improve error return codes when setting rtc time - Minor documentation fix in pata_ns87415.c * 'parisc-5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: ata: pata_ns87415.c: Document support on parisc with superio chip parisc: Add wrapper syscalls to fix O_NONBLOCK flag usage hil/parisc: Disable HIL driver when it gets stuck parisc: Improve error return codes when setting rtc time

git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom Pull random32 updates from Willy Tarreau: "Make prandom_u32() less predictable. This is the cleanup of the latest series of prandom_u32 experimentations consisting in using SipHash instead of Tausworthe to produce the randoms used by the network stack. The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec3b5c) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless. The resulting code was verified to be very slightly faster on x86_64 than what is was with the controversial commit above, though this remains barely above measurement noise. It was also tested on i386 and arm, and build- tested only on arm64" Link: https://lore.kernel.org/netdev/20200808152628.GA27941@SDF.ORG/ * tag '20201024-v4-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom: random32: add a selftest for the prandom32 code random32: add noise from network and scheduling activity random32: make prandom_u32() output unpredictable
