2024-04-23soc: mediatek: cmdq: Add parameter shift_pa to cmdq_pkt_jump()Chun-Kuang Hu
In original design, cmdq_pkt_jump() call cmdq_get_shift_pa() every time to get shift_pa. But the shift_pa is constant value for each SoC, so client driver just need to call cmdq_get_shift_pa() once and pass shift_pa to cmdq_pkt_jump() to prevent frequent function call.

2024-04-21soc: qcom: cmd-db: replace deprecated strncpy with strtomemJustin Stitt
strncpy() is an ambiguous and potentially dangerous interface [1]. We should prefer more robust and less ambiguous alternatives. @query is marked as __nonstring and doesn't need to be NUL-terminated. Since we are doing a string to memory copy, we can use the aptly named "strtomem" -- specifically, the "pad" variant to also ensure NUL-padding throughout the destination buffer.

2024-04-21soc: qcom: rpmh-rsc: Enhance check for VRM in-flight requestMaulik Shah
Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned addresses associated with it. These control voltage, enable state, mode, and in legacy targets, voltage headroom. The current in-flight request checking logic looks for exact address matches. Requests for different addresses of the same RPMh resource as thus not detected as in-flight. Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight request check for VRM requests by ignoring the address offset. This ensures that only one request is allowed to be in-flight for a given VRM resource. This is needed to avoid scenarios where request commands are carried out by RPMh hardware out-of-order leading to LDO regulator over-current protection triggering.

2024-04-08soc: samsung: exynos-asv: Update Energy Model after adjusting voltageLukasz Luba
When the voltage for OPPs is adjusted there is a need to also update Energy Model framework. The EM data contains power values which depend on voltage values. The EM structure is used for thermal (IPA governor) and in scheduler task placement (EAS) so it should reflect the real HW model as best as possible to operate properly. Based on data on Exynos5422 ASV tables the maximum power difference might be ~29%. An Odroid-XU4 (with a random sample SoC in this chip lottery) showed power difference for some OPPs ~20%. Therefore, it's worth to update the EM.

Since SOC_FOO should be deprecated from patch [1], and cleanup for other SoCs is already in the mailing list [2,3,4], we remove the use of SOC_CANAAN and use ARCH_CANAAN for SoCs vendored by Canaan instead from now on. Thus, we should also change the Makefile here to use ARCH_CANAAN. Then, since we have introduced SOC_CANAAN_K210 for K210-specific drivers, we should replace its drivers depends on SOC_CANAAN_K210 and default select when it has the symbol SOC_CANAAN_K210.

2024-03-11soc: sunxi: sram: export register 0 for THS on H616Andre Przywara
The Allwinner H616 SoC contains a mysterious bit at register offset 0x0 in the SRAM control block. If bit 16 is set (the reset value), the temperature readings of the THS are way off, leading to reports about 200C, at normal ambient temperatures. Clearing this bits brings the reported values down to the expected values. The BSP code clears this bit in firmware (U-Boot), and has an explicit comment about this, but offers no real explanation. Experiments in U-Boot show that register 0x0 has no effect on the SRAM C visibility: all tested bit settings still allow full read and write access by the CPU to the whole of SRAM C. Only bit 24 of the register at offset 0x4 makes all of SRAM C inaccessible by the CPU. So modelling the THS switch functionality as an SRAM region would not reflect reality. Since we should not rely on firmware settings, allow other code (the THS driver) to access this register, by exporting it through the already existing regmap. This mimics what we already do for the LDO control and the EMAC register. To avoid concurrent accesses to the same register at the same time, by the SRAM switch code and the regmap code, use the same lock to protect the access. The regmap subsystem allows to use an existing lock, so we just need to hook in there.

2024-02-25soc: samsung: exynos-pmu: Add regmap support for SoCs that protect PMU regsPeter Griffin
Some Exynos based SoCs like Tensor gs101 protect the PMU registers for security hardening reasons so that they are only write accessible in el3 via an SMC call. As most Exynos drivers that need to write PMU registers currently obtain a regmap via syscon (phys, pinctrl, watchdog). Support for the above usecase is implemented in this driver using a custom regmap similar to syscon to handle the SMC call. Platforms that don't secure PMU registers, get a mmio regmap like before. As regmaps abstract out the underlying register access changes to the leaf drivers are minimal. A new API exynos_get_pmu_regmap_by_phandle() is provided for leaf drivers that currently use syscon_regmap_lookup_by_phandle(). This also handles deferred probing.

2024-02-23soc: qcom: pmic_glink_altmode: fix drm bridge use-after-freeJohan Hovold
A recent DRM series purporting to simplify support for "transparent bridges" and handling of probe deferrals ironically exposed a use-after-free issue on pmic_glink_altmode probe deferral. This has manifested itself as the display subsystem occasionally failing to initialise and NULL-pointer dereferences during boot of machines like the Lenovo ThinkPad X13s. Specifically, the dp-hpd bridge is currently registered before all resources have been acquired which means that it can also be deregistered on probe deferrals. In the meantime there is a race window where the new aux bridge driver (or PHY driver previously) may have looked up the dp-hpd bridge and stored a (non-reference-counted) pointer to the bridge which is about to be deallocated. When the display controller is later initialised, this triggers a use-after-free when attaching the bridges: dp -> aux -> dp-hpd (freed) which may, for example, result in the freed bridge failing to attach: [drm:drm_bridge_attach [drm]] *ERROR* failed to attach bridge /soc@0/phy@88eb000 to encoder TMDS-31: -16 or a NULL-pointer dereference: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 ... Call trace: drm_bridge_attach+0x70/0x1a8 [drm] drm_aux_bridge_attach+0x24/0x38 [aux_bridge] drm_bridge_attach+0x80/0x1a8 [drm] dp_bridge_init+0xa8/0x15c [msm] msm_dp_modeset_init+0x28/0xc4 [msm] The DRM bridge implementation is clearly fragile and implicitly built on the assumption that bridges may never go away. In this case, the fix is to move the bridge registration in the pmic_glink_altmode driver to after all resources have been looked up. Incidentally, with the new dp-hpd bridge implementation, which registers child devices, this is also a requirement due to a long-standing issue in driver core that can otherwise lead to a probe deferral loop (see commit fbc35b45f9f6 ("Add documentation on meaning of -EPROBE_DEFER")).
