2019-04-11firmware: imx: enable imx scu general irq functionAnson Huang1-0/+5
The System Controller Firmware (SCFW) controls RTC, thermal and WDOG etc., these resources' interrupt function are managed by SCU. When any IRQ pending, SCU will notify Linux via MU general interrupt channel #3, and Linux kernel needs to call SCU APIs to get IRQ status and notify each module to handle the interrupt. Since there is no data transmission for SCU IRQ notification, so doorbell mode is used for this MU channel, and SCU driver will use notifier mechanism to broadcast to every module which registers the SCU block notifier.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull char/misc driver updates from Greg KH: "Here is the big set of char and misc driver patches for 4.21-rc1. Lots of different types of driver things in here, as this tree seems to be the "collection of various driver subsystems not big enough to have their own git tree" lately. Anyway, some highlights of the changes in here: - binderfs: is it a rule that all driver subsystems will eventually grow to have their own filesystem? Binder now has one to handle the use of it in containerized systems. This was discussed at the Plumbers conference a few months ago and knocked into mergable shape very fast by Christian Brauner. Who also has signed up to be another binder maintainer, showing a distinct lack of good judgement :) - binder updates and fixes - mei driver updates - fpga driver updates and additions - thunderbolt driver updates - soundwire driver updates - extcon driver updates - nvmem driver updates - hyper-v driver updates - coresight driver updates - pvpanic driver additions and reworking for more device support - lp driver updates. Yes really, it's _finally_ moved to the proper parallal port driver model, something I never thought I would see happen. Good stuff. - other tiny driver updates and fixes.

2018-11-26firmware: add remote status update client supportRichard Gong2-2/+65

2018-11-26firmware: add Intel Stratix10 service layer driverRichard Gong2-0/+466
Some features of the Intel Stratix10 SoC require a level of privilege higher than the kernel is granted. Such secure features include FPGA programming. In terms of the ARMv8 architecture, the kernel runs at Exception Level 1 (EL1), access to the features requires Exception Level 3 (EL3). The Intel Stratix10 SoC service layer provides an in kernel API for drivers to request access to the secure features. The requests are queued and processed one by one. ARM’s SMCCC is used to pass the execution of the requests on to a secure monitor (EL3). The header file stratix10-sve-client.h defines the interface between service providers (FPGA manager is one of them) and service layer. The header file stratix10-smc.h defines the secure monitor call (SMC) message protocols used for service layer driver in normal world (EL1) to communicate with secure monitor SW in secure monitor exception level 3 (EL3).
