2025-03-30Merge patch series "Clarify DM_FLAG_PROBE_AFTER_BIND behaviour"Tom Rini
Caleb Connolly <[email protected]> says: In Simon's series reworking autoprobe, a discussion came up about DM_FLAG_PROBE_AFTER_BIND, specifically that it wasn't very clear where this flag should be used. This series implements my suggestions made there to clarify the use of this flag, and fixup the two driver which erroneously apply it to their driver struct (this does nothing).

2023-12-13mailbox: zynqmp: support mulitple mboxes via device-treeTanmay Shah
As of now only one mailbox agent is supported by mailbox driver. On zynqmp platform there are about 7 mailbox agents which can communicate over same IPI channel to U-Boot. This patch series introduces new "zynqmp_ipi_dest" driver which adds one to multi-channel mailbox support. Following format in device-tree is expected as per latest bindings: zynqmp-ipi { compatible = "xlnx,zynqmp-ipi-mailbox"; mbox_1: mailbox@1 { /* New compatible for child node */ compatible = "xlnx,zynqmp-ipi-dest-mailbox"; ... }; ... mbox_n: mailbox@n { compatible = "xlnx,zynqmp-ipi-dest-mailbox"; ... } }; Then mailbox client uses child mailbox node as following: ipi-dest-1 { ... mboxes = <mbox_1 0>, <mbox_1 1>; mbox-names = "tx", "rx"; ... }; New "zynqmp_ipi_dest" driver is for devices with "xlnx,zynqmp-ipi-dest-mailbox" compatible string. This driver will take care of mailbox send recv ops and it replaces previous "zynqmp_ipi" driver. Now "zynqmp_ipi" driver simply binds each child device with "zynqmp_ipi_dest" driver. However, its important to maintain backward comaptibility with previous bindings where child node does not have compatible string. In such case, new driver isn't probed by U-Boot during boot and system fails to boot. To resolve this issue firmware-zynqmp.c driver probes all the IPI parent node driver which binds each child node device with "zynqmp_ipi_dest" driver. This makes sure corresponding child driver will be probed when requested using mbox_get_by_name or mbox_get_by_idx framework calls. This way multiple mailbox agents are supported in device-tree without breaking previous binding support.

2023-10-13treewide: use dev_read_addr_*_ptr() where appropriateMatthias Schiffer
A follow-up to commit 842fb5de424e ("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer") and commit 320a1938b6f7 ("drivers: use devfdt_get_addr_index_ptr when cast to pointer"). In addition to using the *_ptr variants of these functions where the address is cast to a pointer, this also changes devfdt_get_addr_*() to dev_read_addr_*() in a few places. Some variable and field types are changed from fdt_addr_t or phys_addr_t to void* where the cast was happening later. This patch fixes a number of compile warnings when building a 32bit U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error handling where the return value of dev_read_addr() etc. was checked for NULL instead of FDT_ADDR_T_NONE.

2023-07-25mailbox: k3-sec-proxy: Fill non-message tx data fields with 0x0Nishanth Menon
Sec proxy data buffer is 60 bytes with the last of the registers indicating transmission completion. This however poses a bit of a challenge. The backing memory for sec_proxy is regular memory, and all sec proxy does is to trigger a burst of all 60 bytes of data over to the target thread backing ring accelerator. It doesn't do a memory scrub when it moves data out in the burst. When we transmit multiple messages, remnants of previous message is also transmitted which results in some random data being set in TISCI fields of messages that have been expanded forward. The entire concept of backward compatibility hinges on the fact that the unused message fields remain 0x0 allowing for 0x0 value to be specially considered when backward compatibility of message extension is done. So, instead of just writing the completion register, we continue to fill the message buffer up with 0x0 (note: for partial message involving completion, we already do this). This allows us to scale and introduce ABI changes back also work with other boot stages that may have left data in the internal memory. While at this, drop the unused accessor function.
