next/drivers Reset controller changes for v4.20 This adds a new driver for the PDC Global (Power Domain Controller) reset controller found on Qualcomm SDM845 SoCs, fixes a potential use-after-free issue in reset_controller_dev.of_xlate() callbacks from __of_reset_control_get(), and trivially fixes a documentation grammar issue. * tag 'reset-for-4.20' of git://git.pengutronix.de/git/pza/linux: reset: Fix potential use-after-free in __of_reset_control_get() reset: qcom: PDC Global (Power Domain Controller) reset controller dt-bindings: reset: Add PDC Global binding for SDM845 SoCs reset: Grammar s/more then once/more than once/ Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The System Controller Firmware (SCFW) is a low-level system function which runs on a dedicated Cortex-M core to provide power, clock, and resource management. It exists on some i.MX8 processors. e.g. i.MX8QM (QM, QP), and i.MX8QX (QXP, DX). This patch implements the SCU firmware IPC function and the common message sending API sc_call_rpc.

Calling of_node_put() decreases the reference count of a device tree object, and may free some data. However, the of_phandle_args structure embedding it is passed to reset_controller_dev.of_xlate() after that, so it may still be accessed. Move the call to of_node_put() down to fix this.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers TI sysc driver changes for v4.20 merge window This series gets rid of the SYSC_QUIRK_RESOURCE_PROVIDER to make device detection happen mostly only if #define DEBUG is set. Few core devices still need to be detected to set legacy quirks. We also add support for booting am335x, am437x and dra7 SoCs with L4 devices defined in device tree instead of legacy platform data. And finally we simplify suspend with just SET_NOIRQ_SYSTEM_SLEEP_PM_OPS and dropping the custom functions that were attempting to work around issues that really turned out to be child device driver related issues. Apologies for a late pull request, debugging the suspend issues took a while and I did not want to send these changes until that got sorted out. * tag 'omap-for-v4.20/ti-sysc-take2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: bus: ti-sysc: Just use SET_NOIRQ_SYSTEM_SLEEP_PM_OPS bus: ti-sysc: Make some warnings debug only bus: ti-sysc: Detect devices for debug on dra7 bus: ti-sysc: Detect timer and gpio on dra7 bus: ti-sysc: Detect devices on am335x when DEBUG is enabled bus: ti-sysc: Detect more devices on am473x for debugging bus: ti-sysc: Update revision masks to support am437x bus: ti-sysc: Defer suspend as needed Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2018-09-27soc: fsl: qbman: add APIs to retrieve the probing statusLaurentiu Tudor4-0/+38
Add a couple of new APIs to check the probing status of qman and bman: 'int bman_is_probed()' and 'int qman_is_probed()'. They return the following values. * 1 if qman/bman were probed correctly * 0 if qman/bman were not yet probed * -1 if probing of qman/bman failed Drivers that use qman/bman driver services are required to use these APIs before calling any functions exported by qman or bman drivers or otherwise they will crash the kernel. The APIs will be used in the following couple of qbman portal patches and later in the series in the dpaa1 ethernet driver.

Firmware-debug provides debugfs interface to all APIs. Debugfs can be used to call firmware APIs with required parameters. Usage: * Calling firmware API through debugfs: # echo "<api-name> <arg1> .. <argn>" > /sys/.../zynqmp-firmware/pm * Read output of last called firmware API: # cat /sys/.../zynqmp-firmware/pm Refer ug1200 for more information on these APIs: * https://www.xilinx.com/support/documentation/user_guides/ug1200-eemi-api.pdf Add basic debugfs file to get API version.
