Memory controller drivers for v7.2 1. Tegra MC/EMC: - Handle system sleep, necessary to re-program registers after system resume. A few more improvements. - Add Tegra114 and Tegra238 Memory Controller, and Tegra114 External MC support. - Grow Tegra264 support. 2. Renesas XSPI: Document RZ/T2H and RZ/N2H variants, compatible with existing devices. * tag 'memory-controller-drv-7.2' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl: memory: tegra264: Add full set of MC clients dt-bindings: memory: tegra264: Add full set of MC client IDs memory: tegra264: Skip clients without bpmp_id or type memory: renesas-rpc-if: Fix duplicate device name on multi-instance platforms dt-bindings: memory: renesas,rzg3e-xspi: Add RZ/T2H and RZ/N2H support memory: omap-gpmc: Silence W=1 kerneldoc warnings memory: tegra114-emc: Simplify tegra114_emc_interconnect_init() error message memory: tegra114-emc: Do not print error on icc_node_create() failure memory: tegra: Fix possible null pointer dereference memory: tegra: Add Tegra114 EMC driver memory: tegra: Implement EMEM regs and ICC ops for Tegra114 dt-bindings: memory: Document Tegra114 External Memory Controller dt-bindings: memory: Document Tegra114 Memory Controller memory: tegra: Add Tegra238 MC support dt-bindings: memory: tegra: Add nvidia,tegra238-mc compatible memory: tegra: Restore MC interrupt masks on resume memory: tegra: Wire up system sleep PM ops memory: tegra: Make ->resume() callback return void memory: tegra: Deduplicate rate request management code memory: atmel-ebi: Allow deferred probing Signed-off-by: Arnd Bergmann

soc/tegra: pmc: Move legacy code behind CONFIG_ARM guard

2026-05-31T05:21:14+00:00

None of this legacy code is needed on 64-bit ARM devices, so it can be moved behind a corresponding preprocessor guard. This more cleanly separates out the legacy code from code needed on current platforms. Acked-by: Jon Hunter Signed-off-by: Thierry Reding

soc/tegra: pmc: Remove unused legacy functions

2026-05-31T05:21:14+00:00

All callers of these functions have been replaced by their variants taking a PMC context as an input, so they are no longer used and can be removed. Acked-by: Jon Hunter Signed-off-by: Thierry Reding

memory: tegra: Make ->resume() callback return void

2026-05-04T17:17:48+00:00

tegra186_mc_resume() is the only implementation of the SoC ->resume() op in struct tegra_mc_ops, and it can never fail as the SID override loop has no error path. The int return value is therefore not used. Change the prototype to return void so callers do not need to deal with a value that is always 0. If a future SoC needs to report failure from resume, an int return type can be reintroduced then.

Merge tag 'tegra-for-7.1-firmware' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into soc/drivers

2026-04-02T21:13:02+00:00

firmware: tegra: Changes for v7.1-rc1 This introduces a new API for the BPMP to be pass along a specifier from DT when getting a reference from a phandle. This is used to reference specific instances of the PCI controller on Tegra264. The ABI header for BPMP is updated to the latest version and BPMP APIs now use the more intuitive ENODEV instead of the non SUSV4 ENOTSUPP error code for stub implementations. * tag 'tegra-for-7.1-firmware' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: soc/tegra: bpmp: Use ENODEV instead of ENOTSUPP firmware: tegra: bpmp: Add tegra_bpmp_get_with_id() function soc/tegra: Update BPMP ABI header firmware: tegra: bpmp: Rename Tegra239 to Tegra238 Signed-off-by: Arnd Bergmann

soc/tegra: bpmp: Use ENODEV instead of ENOTSUPP

2026-03-27T15:30:54+00:00

ENOTSUPP is not a SUSV4 error code and checkpatch will warn about it. It is also not very descriptive in the context of BPMP, so use the ENODEV error code instead. For the stub implementations this is a more accurate description of what the failure is. Signed-off-by: Thierry Reding

firmware: tegra: bpmp: Add tegra_bpmp_get_with_id() function

2026-03-27T15:24:36+00:00

Some device tree bindings need to specify a parameter along with a BPMP phandle reference to designate the ID associated with a given controller that needs to interoperate with BPMP. Typically this is specified as an extra cell in the nvidia,bpmp property, so add a helper to parse this ID while resolving the phandle reference. Signed-off-by: Thierry Reding

soc/tegra: Update BPMP ABI header

2026-03-27T15:23:53+00:00

This update primarily adds various new commands and MRQs for Tegra264, but also contains a few new annotations and fixes. Signed-off-by: Thierry Reding

firmware: tegra: bpmp: Rename Tegra239 to Tegra238

2026-03-19T16:03:55+00:00

This chip identifies as Tegra238, so update the BPMP ABI header to refer to it by the correct name. Reviewed-by: Jon Hunter Signed-off-by: Thierry Reding

memory: tegra: Prepare for supporting multiple intmask registers

2026-03-07T17:02:41+00:00

Add a new structure for the intmask register e.g. MC_INTMASK_0 and it's mask value. Add an array of these new structures to prepare for supporting multiple intmask registers. This is done in preparation for adding support for Tegra264 which supports multiple intmask registers.
