2020-09-24docs: rewrite admin-guide/sysctl/abi.rstStephen Kitt1-0/+2
Following the structure used in sysctl/kernel.rst, this updates abi.rst to use ReStructured Text more fully and updates the entries to match current kernels: * the list of files is now the table of contents; * links are used to point to other documentation and other sections; * all the existing entries are no longer present, so this removes them; * document vsyscall32. Mentions of the kernel version are dropped. Since the document is entirely rewritten, I've replaced the copyright statement.

2020-09-24gpio/aspeed-sgpio: enable access to all 80 input & output sgpiosJeremy Kerr1-2/+3
Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines, corresponding to the 80 status bits available in hardware. Each of these lines can be configured as either an input or an output. However, each of these GPIOs is actually an input *and* an output; we actually have 80 inputs plus 80 outputs. This change expands the maximum number of GPIOs to 160; the lower half of this range are the input-only GPIOs, the upper half are the outputs. We fix the GPIO directions to correspond to this mapping. This also fixes a bug when setting GPIOs - we were reading from the input register, making it impossible to set more than one output GPIO.

2020-09-24dt-bindings: rtc: let aux-voltage-chargeable supersede trickle-diode-disableBastian Krause1-0/+10
Some RTCs can be equipped with a chargeable battery or supercap. Every RTC allowing this whose driver's implement it are charged by default. To disable this the trickle-diode-disable flag exists. If a driver did not support charging and some time later one wants to add that feature, there is currently no way to do it without breaking dt backwards compatibility. RTCs on boards without the trickle-diode-disable flag in their device tree would suddenly charge their battery/supercap which is a change in behavior. Change that by introducing aux-voltage-chargeable, not as a flag but as a uint32 enum allowing to set "do not charge" (0) or "charge" (1). This dt property is optional, so we can now distinguish these cases. Care must be taken to support the old behavior for device trees without aux-voltage-chargeable nonetheless to stay compatible.

2020-09-23hwmon (pmbus) use simple i2c probe functionStephen Kitt2-6/+4
pmbus_do_probe doesn't use the id information provided in its second argument, so this can be removed, which then allows using the single-parameter i2c probe function ("probe_new") for probes. This avoids scanning the identifier tables during probes. Drivers which didn't use the id are converted as-is; drivers which did are modified as follows: * if the information in i2c_client is sufficient, that's used instead (client->name); * configured v. probed comparisons are performed by comparing the configured name to the detected name, instead of the ids; this involves strcmp but is still cheaper than comparing all the device names when scanning the tables; * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. Additionally, the mismatch message in the ltc2978 driver is adjusted so that it no longer assumes that the driver_data is an index into ltc2978_id.

The J7200 SoC is a part of the K3 Multicore SoC architecture platform. It is targeted for automotive gateway, vehicle compute systems, Vehicle-to-Vehicle (V2V) and Vehicle-to-Everything (V2X) applications. The SoC aims to meet the complex processing needs of modern embedded products. Some highlights of this SoC are: * Dual Cortex-A72s in a single cluster, two clusters of lockstep capable dual Cortex-R5F MCUs and a Centralized Device Management and Security Controller (DMSC). * Configurable L3 Cache and IO-coherent architecture with high data throughput capable distributed DMA architecture under NAVSS. * Integrated Ethernet switch supporting up to a total of 4 external ports in addition to legacy Ethernet switch of up to 2 ports. * Upto 1 PCIe-GEN3 controller, 1 USB3.0 Dual-role device subsystems, 20 MCANs, 3 McASP, eMMC and SD, OSPI/HyperBus memory controller, I3C and I2C, eCAP/eQEP, eHRPWM among other peripherals. * One hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL management.

2020-09-23dt-bindings: reset: Updated binding for Versal reset driverSai Krishna Potthuri1-4/+7
Added documentation and Versal reset indices to describe about Versal reset driver bindings. In Versal all reset indices includes Class, SubClass, Type, Index information whereas class refers to clock, reset, power etc., Underlying firmware in Versal have such classification and expects the ID to be this way. [13:0] - Index bits [19:14] - Type bits [25:20] - SubClass bits [31:26] - Class bits.

2020-09-23cpuidle: record state entry rejection statisticsLina Iyer1-0/+9
CPUs may fail to enter the chosen idle state if there was a pending interrupt, causing the cpuidle driver to return an error value. Record that and export it via sysfs along with the other idle state statistics. This could prove useful in understanding behavior of the governor and the system during usecases that involve multiple CPUs.
