* misc: Explicitly include correct DT includesRob Herring2023-08-041-1/+2
| | | | | | | | | | | | | | | | The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

* misc: xilinx_tmr_manager: Use devm_platform_get_and_ioremap_resource()Yangtao Li2023-08-041-2/+1
| | | | | | | | | | | Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does.

* drivers: misc: Add Support for TMR ManagerAppana Durga Kedareswara rao2023-01-201-0/+220
Triple Modular Redundancy(TMR) subsystem contains three microblaze cores, subsystem is fault-tolerant and continues to operate nominally after encountering an error. Together with the capability to detect and recover from errors, the implementation ensures the reliability of the entire subsystem. TMR Manager is responsible for performing recovery of the subsystem detects the fault via a break signal it invokes microblaze software break handler which calls the tmr manager driver api to update the error count and status, added support for fault detection feature via sysfs interface. Usage: To know the break handler count(Error count): cat /sys/devices/platform/amba_pl/44a10000.tmr_manager/errcnt Signed-off-by: Appana Durga Kedareswara rao <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
