Add ZynqMP firmware IOCTL API to control and configure devices like PLLs, SD, Gem, etc. Signed-off-by: Rajan Vaja <[email protected]> Signed-off-by: Jolly Shah <[email protected]> Acked-by: Olof Johansson <[email protected]> Signed-off-by: Michal Simek <[email protected]>
2018-09-26firmware: xilinx: Add debugfs for query data APIRajan Vaja1-0/+28
Add debugfs file to query platform specific data from firmware using debugfs interface. Signed-off-by: Rajan Vaja <[email protected]> Signed-off-by: Jolly Shah <[email protected]> Signed-off-by: Michal Simek <[email protected]>
2018-09-26firmware: xilinx: Add debugfs interfaceRajan Vaja5-0/+259
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.

2018-09-26firmware: xilinx: Add clock APIsRajan Vaja1-2/+184
Add clock APIs to control clocks through firmware interface. Signed-off-by: Rajan Vaja <[email protected]> Signed-off-by: Jolly Shah <[email protected]> Signed-off-by: Michal Simek <[email protected]>
2018-09-26firmware: xilinx: Add query data APIRajan Vaja1-0/+14
Add ZynqMP firmware query data API to query platform specific information(clocks, pins) from firmware. Signed-off-by: Rajan Vaja <[email protected]> Signed-off-by: Jolly Shah <[email protected]> Signed-off-by: Michal Simek <[email protected]>
2018-09-26firmware: xilinx: Add Zynqmp firmware driverRajan Vaja3-0/+342
This patch is adding communication layer with firmware. Firmware driver provides an interface to firmware APIs. Interface APIs can be used by any driver to communicate to PMUFW(Platform Management Unit). All requests go through ATF.
