soc: qcom: pd-mapper: Add QCM6490 PD maps

2024-12-14T19:03:39Z

[ Upstream commit 31a95fe0851afbbc697b6be96c8a81a01d65aa5f ] The QCM6490 is a variant of SC7280, with the usual set of protection domains, and hence the need for a PD-mapper. In particular USB Type-C port management and battery management is pmic_glink based. Add an entry to the kernel, to avoid the need for userspace to provide this service.

Convert the data to use designated initializers to make it easier both to understand and add/update the slice configuration data.

[ Upstream commit 78261cb08f06c93d362cab5c5034bf5899bc7552 ] This loop is supposed to break if the frequency returned from clk_round_rate() is the same as on the previous iteration. However, that check doesn't make sense on the first iteration through the loop. It leads to reading before the start of these->clk_perf_tbl[] array.

2024-11-04T13:23:09Z

Qualcomm driver fixes for v6.12 The Qualcomm EDAC driver's configuration of interrupts is made optional, to avoid violating security constriants on X Elite platform . The SCM drivers' detection mechanism for the presence of SHM bridge in QTEE, is corrected to handle the case where firmware successfully returns that the interface isn't supported. The GLINK driver and the PMIC GLINK interface is updated to handle buffer allocation issues during initialization of the communication channel. Allocation error handling in the socinfo dirver is corrected, and then the fix is corrected. * tag 'qcom-drivers-fixes-for-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: pmic_glink: Handle GLINK intent allocation rejections rpmsg: glink: Handle rejected intent request better soc: qcom: socinfo: fix revision check in qcom_socinfo_probe() firmware: qcom: scm: Return -EOPNOTSUPP for unsupported SHM bridge enabling EDAC/qcom: Make irq configuration optional firmware: qcom: scm: fix a NULL-pointer dereference firmware: qcom: scm: suppress download mode error soc: qcom: Add check devm_kasprintf() returned value MAINTAINERS: Qualcomm SoC: Match reserved-memory bindings Link: https://lore.kernel.org/r/20241101161455.746290-1-andersson@kernel.org Signed-off-by: Arnd Bergmann

soc: qcom: pmic_glink: Handle GLINK intent allocation rejections

2024-10-24T18:03:37Z

Some versions of the pmic_glink firmware does not allow dynamic GLINK intent allocations, attempting to send a message before the firmware has allocated its receive buffers and announced these intent allocations will fail. When this happens something like this showns up in the log: pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to send altmode request: 0x10 (-125) pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to request altmode notifications: -125 ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI read request: -125 qcom_battmgr.pmic_glink_power_supply pmic_glink.power-supply.0: failed to request power notifications GLINK has been updated to distinguish between the cases where the remote is going down (-ECANCELED) and the intent allocation being rejected (-EAGAIN). Retry the send until intent buffers becomes available, or an actual error occur. To avoid infinitely waiting for the firmware in the event that this misbehaves and no intents arrive, an arbitrary 5 second timeout is used. This patch was developed with input from Chris Lew.

soc: qcom: socinfo: fix revision check in qcom_socinfo_probe()

2024-10-24T14:46:20Z

In success case, the revision holds a non-null pointer. The current logic incorrectly returns an error for a non-null pointer, whereas it should return an error for a null pointer. The socinfo driver for IPQ9574 and IPQ5332 is currently broken, resulting in the following error message qcom-socinfo qcom-socinfo: probe with driver qcom-socinfo failed with error -12 Add a null check for the revision to ensure it returns an error only in failure case (null pointer).

EDAC/qcom: Make irq configuration optional

2024-10-06T03:17:08Z

On most modern qualcomm SoCs, the configuration necessary to enable the Tag/Data RAM related irqs being propagated to the SoC irq controller is already done in firmware (in DSF or 'DDR System Firmware') On some like the x1e80100, these registers aren't even accesible to the kernel causing a crash when edac device is probed. Hence, make the irq configuration optional in the driver and mark x1e80100 as the SoC on which this should be avoided.

Pull SoC driver updates from Arnd Bergmann: "The driver updates seem larger this time around, with changes is many of the SoC specific drivers, both the custom drivers/soc ones and the closely related subsystems (memory, bus, firmware, reset, ...). The at91 platform gains support for sam9x7 chips in the soc and power management code. This is the latest variant of one of the oldest still supported SoC families, using the ARM9 (ARMv5) core. As usual, the qualcomm snapdragon platform gets a ton of updates in many of their drivers to add more features and additional SoC support. Most of these are somewhat firmware related as the platform has a number of firmware based interfaces to the kernel. A notable addition here is the inclusion of trace events to two of these drivers. Herve Codina and Christophe Leroy are now sending updates for drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC and Arm specific platforms and has previously been problematic to maintain. The first update here contains support for newer PowerPC variants and some cleanups. The turris mox firmware driver has a number of updates, mostly cleanups. The Arm SCMI firmware driver gets a major rework to modularize the existing code into separately loadable drivers for the various transports, the addition of custom NXP i.MX9 interfaces and a number of smaller updates. The Arm FF-A firmware driver gets a feature update to support the v1.2 version of the specification. The reset controller drivers have some smaller cleanups and a newly added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs. The memory controller drivers get some cleanups and refactoring for Tegra, TI, Freescale/NXP and a couple more platforms. Finally there are lots of minor updates to firmware (raspberry pi, tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic, mediatek) drivers and their DT bindings" * tag 'soc-drivers-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (212 commits) firmware: imx: remove duplicate scmi_imx_misc_ctrl_get() platform: cznic: turris-omnia-mcu: Fix error check in omnia_mcu_register_trng() bus: sunxi-rsb: Simplify code with dev_err_probe() soc: fsl: qe: ucc: Export ucc_mux_set_grant_tsa_bkpt soc: fsl: cpm1: qmc: Fix dependency on fsl_soc.h dt-bindings: arm: rockchip: Add rk3576 compatible string to pmu.yaml soc: fsl: qbman: Remove redundant warnings soc: fsl: qbman: Use iommu_paging_domain_alloc() MAINTAINERS: Add QE files related to the Freescale QMC controller soc: fsl: cpm1: qmc: Handle QUICC Engine (QE) soft-qmc firmware soc: fsl: cpm1: qmc: Add support for QUICC Engine (QE) implementation soc: fsl: qe: Add missing PUSHSCHED command soc: fsl: qe: Add resource-managed muram allocators soc: fsl: cpm1: qmc: Introduce qmc_version soc: fsl: cpm1: qmc: Rename SCC_GSMRL_MODE_QMC soc: fsl: cpm1: qmc: Handle RPACK initialization soc: fsl: cpm1: qmc: Rename qmc_chan_command() soc: fsl: cpm1: qmc: Introduce qmc_{init,exit}_xcc() and their CPM1 version soc: fsl: cpm1: qmc: Introduce qmc_init_resource() and its CPM1 version soc: fsl: cpm1: qmc: Re-order probe() operations ...
