https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/drivers RISC-V SoC drivers for v6.4 Microchip: Mailbox controller & client changes for the system controller on PolarFire SoC. The controller bits have been acked by Jassi. Primarily the changes work around a "hardware" bug (really the system controller's software, but it may as well be hardware as customers cannot change it) where interrupts are not generated if a service fails. The mailbox controller driver is tweaked to use polling, rather than interrupt, mode and there are some changes to timeout code required in the client driver as a result. There's some opportunistic cleanup that I performed while doing the swap too.

2023-04-03Merge patch series "mailbox,soc: mpfs: add support for fallible services"Conor Dooley
Conor Dooley <conor@kernel.org> says: Here are some fixes for the system controller on PolarFire SoC that I ran into while implementing support for using the system controller to re-program the FPGA. A few are just minor bits that I fixed in passing, but the bulk of the patchset is changes to how the mailbox figures out if a "service" has completed. Prior to implementing this particular functionality, the services requested from the system controller, via its mailbox interface, always triggered an interrupt when the system controller was finished with the service. Unfortunately some of the services used to validate the FPGA images before programming them do not trigger an interrupt if they fail. For example, the service that checks whether an FPGA image is actually a newer version than what is already programmed, does not trigger an interrupt, unless the image is actually newer than the one currently programmed. If it has an earlier version, no interrupt is triggered and a status is set in the system controller's status register to signify the reason for the failure. In order to differentiate between the service succeeding & the system controller being inoperative or otherwise unable to function, I had to switch the controller to poll a busy bit in the system controller's registers to see if it has completed a service. This makes sense anyway, as the interrupt corresponds to "data ready" rather than "tx done", so I have changed the mailbox controller driver to do that & left the interrupt solely for signalling data ready. It just so happened that all of the services that I had worked with and tested up to this point were "infallible" & did not set a status, so the particular code paths were never tested.

2023-04-03soc: microchip: mpfs: handle timeouts and failed services differentlyConor Dooley
The system controller will only deliver an interrupt if a service succeeds. This leaves us in the unfortunate position with current code where there is no way to differentiate between a legitimate timeout where the service has not completed & where it has completed, but failed. mbox_send_message() has its own completion, and it will time out of the system controller does not lower the busy flag. In this case, a timeout has occurred and the error can be propagated back to the caller. If the busy flag is lowered, but no interrupt has arrived to trigger the rx callback, the service can be deemed to have failed. Report -EBADMSG in this case so that callers can differentiate.

2023-04-03mailbox: mpfs: check the service status in .tx_done()Conor Dooley
Services are supposed to generate an interrupt once completed, whether or not they have do so successfully. What appears to be a bug in the system controller means that interrupts are only generated for *successful* services. Currently, the status of a service is only checked in the mpfs_mbox_rx_data() once an interrupt is received. As it turns out, this is not really helpful where the potentially buggy behaviour is present, as we'll only see the status for successes where it is moot anyway. Jassi suggested moving the check to the .tx_done() callback instead. This makes sense, as the busy bit that tx_done() is polling will be lowered on completion, regardless of whether the service passed or failed. That allows us to check the status bits for all services, whether they generate an interrupt or not & pass something more informative than -EBADMSG back to the drivers implementing individual services.

The system controller registers on PolarFire SoC are 32 bits wide, so 16 + 16 as the first input to GENMASK_ULL() gives a 33 bit wide mask. It probably should have been immediately obvious when it was pointed out during review that the width required using GENMASK_ULL() - but I scarcely knew what I was doing at the time and missed it. The mistake ends up being moot as it is a mask after all, but it is incorrect and should be fixed. No functional change intended.

2023-04-03tee: optee: Add SMC for loading OP-TEE imageJeffrey Kardatzke
Adds an SMC call that will pass an OP-TEE binary image to EL3 and instruct it to load it as the BL32 payload. This works in conjunction with a feature added to Trusted Firmware for ARMv8 and above architectures that supports this. The main purpose of this change is to facilitate updating the OP-TEE component on devices via a rootfs change rather than having to do a firmware update. Further details are linked to in the Kconfig file.

2023-03-30optee: add per cpu asynchronous notificationEtienne Carriere
Implements use of per-cpu irq for optee asynchronous notification. Existing optee async notif implementation allows OP-TEE world to raise an interrupt on which Linux optee driver will query some pending events. This change allows the signaling interrupt to be a per-cpu interrupt as with Arm GIC PPIs. Using a PPI instead of an SPI is useful when no GIC lines are provisioned in the chip design and there are spare PPI lines.

2023-03-27firmware: meson_sm: populate platform devices from sm device tree dataDmitry Rokosov
In some meson boards, secure monitor device has children, for example, power secure controller. By default, secure monitor isn't the bus in terms of device tree subsystem, so the of_platform initialization code doesn't populate its device tree data. As a result, secure monitor's children aren't probed at all. Run the 'of_platform_populate()' routine manually to resolve such issues.
