2017-11-09soc: amlogic: meson-gx-pwrc-vpu: fix power-off when powered by bootloaderNeil Armstrong1-10/+19
In the case the VPU power domain has been powered on by the bootloader and no driver are attached to this power domain, the genpd will power it off after a certain amount of time, but the clocks hasn't been enabled by the kernel itself and the power-off will trigger some faults. This patch enable the clocks to have a coherent state for an eventual poweroff and switches to the pm_domain_always_on_gov governor.

2017-11-02drivers/firmware: psci_checker: Add missing destroy_timer_on_stack()Lorenzo Pieralisi1-0/+1
The PSCI checker suspend_test_thread() function (ie executed for the suspend test) requires an on-stack timer to carry out the test it executes; it sets it up through the setup_timer_on_stack() API. setup_timer_on_stack() requires its counterpart destroy_timer_on_stack() to be called when the timer is disposed of but the PSCI checker code is currently missing that call, leaving the timer object in an incosistent state when the PSCI checker stops the thread executing the suspend test. Add the missing destroy_timer_on_stack() call to fix the omission.

2017-10-22soc: qcom: Remote filesystem memory driverBjorn Andersson4-0/+284
The Qualcomm remote file system protocol is used by certain remoteprocs, in particular the modem, to read and write persistent storage in platforms where only the application CPU has physical storage access. The protocol is based on a set of QMI-encoded control-messages and a shared memory buffer for exchaning the data. This driver implements the latter, providing the user space service access to the carved out chunk of memory.

2017-10-22of: reserved_mem: Accessor for acquiring reserved_memBjorn Andersson2-0/+31
In some cases drivers referencing a reserved-memory region might want to remap the entire region, but when defining the reserved-memory by "size" the client driver has no means to know the associated base address of the reserved memory region. This patch adds an accessor for such drivers to acquire a handle to their associated reserved-memory for this purpose. A complicating factor for the implementation is that the reserved_mem objects are created from the flattened DeviceTree, as such we can't use the device_node address for comparison. Fortunately the name of the node will be used as "name" of the reserved_mem and will be used when building the full_name, so we can compare the "name" with the basename of the full_name to find the match.

2017-10-20soc: mediatek: pwrap: refactor pwrap_init for the various PMIC typesSean Wang1-40/+90
pwrap initialization is highly associated with the base SoC and the target PMICs, so slight refactorization is made here for allowing pwrap_init to run on those PMICs with different capability from the previous MediaTek PMICs and the determination for the enablement of the pwrap capability depending on PMIC type. Apart from this, the patch makes the driver more extensible especially when more PMICs join into the pwrap driver.

2017-10-20soc: mediatek: pwrap: add pwrap_write32 for writing in 32-bit modeSean Wang1-16/+54
Some regulators such as MediaTek MT6380 also has to be written in 32-bit mode. So the patch adds pwrap_write32, rename old pwrap_write into pwrap_write16 and one additional function pointer is introduced for increasing flexibility allowing the determination which mode is used by the pwrap slave detection through device tree.

2017-10-19thermal: Add Tegra BPMP thermal sensor driverMikko Perttunen4-2/+273
On Tegra186, the BPMP (Boot and Power Management Processor) exposes an interface to thermal sensors on the system-on-chip. This driver implements access to the interface. It supports reading the temperature, setting trip points and receiving notification of a tripped trip point.

2017-10-19firmware: tegra: Add BPMP debugfs supportTimo Alho4-1/+465
Tegra power management firmware running on the co-processor (BPMP) implements a simple pseudo file system akin to debugfs. The file system can be used for debugging purposes to examine and change the status of selected resources controlled by the firmware (such as clocks, resets, voltages, powergates, ...). Add support to "mirror" the firmware's file system to debugfs. At boot, query firmware for a list of all possible files and create corresponding debugfs entries. Read/write of individual files is implemented by sending a Message ReQuest (MRQ) that passes the full file path name and data to firmware via DRAM.
