2023-01-20soc: starfive: Add StarFive JH71XX pmu driverWalker Chen5-0/+400
Add pmu driver for the StarFive JH71XX SoC. As the power domains provider, the Power Management Unit (PMU) is designed for including multiple PM domains that can be used for power gating of selected IP blocks for power saving by reduced leakage current. It accepts software encourage command to switch the power mode of SoC.

2022-12-28soc: qcom: dcc: Add driver support for Data Capture and Compare unit(DCC)Souradeep Chowdhury3-0/+1308
The DCC is a DMA Engine designed to capture and store data during system crash or software triggers. The DCC operates based on user inputs via the debugfs interface. The user gives addresses as inputs and these addresses are stored in the dcc sram. In case of a system crash or a manual software trigger by the user through the debugfs interface, the dcc captures and stores the values at these addresses. This patch contains the driver which has all the methods pertaining to the debugfs interface, auxiliary functions to support all the four fundamental operations of dcc namely read, write, read/modify/write and loop. The probe method here instantiates all the resources necessary for dcc to operate mainly the dedicated dcc sram where it stores the values. The DCC driver can be used for debugging purposes without going for a reboot since it can perform software triggers as well based on user inputs. Also add the documentation for debugfs entries which explains the functionalities of each debugfs file that has been created for dcc. The following is the justification of using debugfs interface over the other alternatives like sysfs/ioctls i) As can be seen from the debugfs attribute descriptions, some of the debugfs attribute files here contains multiple arguments which needs to be accepted from the user. This goes against the design style of sysfs. ii) The user input patterns have been made simple and convenient in this case with the use of debugfs interface as user doesn't need to shuffle between different files to execute one instruction as was the case on using other alternatives.

My previous patch to prevent BPMP from being enabled on big endian kernels caused a build regression: WARNING: unmet direct dependencies detected for TEGRA_BPMP Depends on [n]: ARCH_TEGRA [=y] && TEGRA_HSP_MBOX [=y] && TEGRA_IVC [=y] && !CPU_BIG_ENDIAN [=y] Selected by [y]: - ARCH_TEGRA_186_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y] - ARCH_TEGRA_194_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y] - ARCH_TEGRA_234_SOC [=y] && ARCH_TEGRA [=y] && ARM64 [=y] Add even more such dependencies for the SoC types that use the BPMP driver.

Power reset maybe generate unexpected signal. In order to avoid the glitch issue, we need to enable isolation first to guarantee the stable signal when power reset is triggered.
