pmdomain: xilinx: Move Kconfig option to the pmdomain subsystemThe Kconfig option belongs closer to the corresponding implementation,hence let's move it from the soc subsystem to the pmdomain subsystem.Cc: Michal Simek Signed-off-by: Ulf Hansson List of files: /linux-6.15/drivers/soc/xilinx/Kconfig

c7fdb240 - drivers: soc: xilinx: add xilinx event management driver

Mon, 29 Nov 2021 07:02:14 +0000

drivers: soc: xilinx: add xilinx event management driverXilinx event management driver provides an interface to subscribe orunsubscribe for the event/callback supported by firmware. An agent can usethis driver to register for Error Event, Device Event and Suspend callback.This driver only allows one agent per event to do registration. Driver willreturn an error in case of multiple registration for the same event.This driver gets notification from firmware through TF-A as SGI. Duringinitialization, event manager driver register handler for SGI used fornotification. It also provides SGI number info to TF-A by usingIOCTL_REGISTER_SGI call to TF-A.After receiving notification from firmware, the driver makes an SMC call toTF-A to get IPI data. From the IPI data provided by TF-A, event manageridentified the cause of event and forward that event/callback notificationto the respective subscribed driver. After this, in case of Error Event,driver performs unregistration as firmware expecting from agent to dore-registration if the agent wants to get notified on the second occurrenceof an error event.Add new IOCTL id IOCTL_REGISTER_SGI = 25 which is used to register SGI onTF-A.Older firmware doesn't have all required support for event handling whichis required by the event manager driver. So add check for the registernotifier version in the event manager driver.Xilinx event management driver provides support to subscribe for multipleerror events with the use of Event Mask in a single call ofxlnx_register_event(). Agent driver can provide 'Event' parameter value asORed of multiple event masks to register single callback for multipleevents. For example, to register callback for event=0x1 and event=0x2 forthe given node, agent can provide event=0x3 (0x1 | 0x2). It is not possibleto register multiple events for different nodes in a single registrationcall.Also provide support to receive multiple error events as in singlenotification from firmware and then forward it to subscribed drivers viaregistered callback one by one.Acked-by: Michal Simek Signed-off-by: Tejas Patel Signed-off-by: Rajan Vaja Signed-off-by: Abhyuday Godhasara Link: https://lore.kernel.org/r/20211129070216.30253-2-abhyuday.godhasara@xilinx.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/soc/xilinx/Kconfig

a2fe7baa - clk: xilinx: move xlnx_vcu clock driver from soc

Thu, 21 Jan 2021 07:16:59 +0000

clk: xilinx: move xlnx_vcu clock driver from socThe xlnx_vcu driver is actually a clock controller driver which providesclocks that can be used by a driver for the encoder/decoder units. Thereis no reason to keep this driver in soc. Move the driver to clk.NOTE: The register mapping actually contains registers for AXIperformance monitoring, but these are not used by the driver.Signed-off-by: Michael Tretter Acked-by: Michal Simek Link: https://lore.kernel.org/r/20210121071659.1226489-16-m.tretter@pengutronix.deSigned-off-by: Stephen Boyd List of files: /linux-6.15/drivers/soc/xilinx/Kconfig

soc: xilinx: vcu: register PLL as fixed rate clockCurrently, xvcu_pll_set_rate configures the PLL to a clock rate that ispre-calculated when probing the driver. To still make the clockframework aware of the PLL and to allow to configure other clocks basedon the PLL rate, register the PLL as a fixed rate clock.Signed-off-by: Michael Tretter Acked-by: Michal Simek Link: https://lore.kernel.org/r/20210121071659.1226489-8-m.tretter@pengutronix.deSigned-off-by: Stephen Boyd List of files: /linux-6.15/drivers/soc/xilinx/Kconfig

Wed, 08 Apr 2020 15:52:15 +0000

drivers: soc: xilinx: fix firmware driver Kconfig dependencyThe firmware driver is optional, but the power driver depends on it,which needs to be reflected in Kconfig to avoid link errors:aarch64-linux-ld: drivers/soc/xilinx/zynqmp_power.o: in function `zynqmp_pm_isr':zynqmp_power.c:(.text+0x284): undefined reference to `zynqmp_pm_invoke_fn'The firmware driver can probably be allowed for compile-testing aswell, so it's best to drop the dependency on the ZYNQ platformhere and allow building as long as the firmware code is built-in.Fixes: ab272643d723 ("drivers: soc: xilinx: Add ZynqMP PM driver")Signed-off-by: Arnd Bergmann Link: https://lore.kernel.org/r/20200408155224.2070880-1-arnd@arndb.deSigned-off-by: Michal Simek List of files: /linux-6.15/drivers/soc/xilinx/Kconfig
