memory: omap-gpmc: Drop custom PM calls with cpu_pm notifier

2021-07-29T07:02:27Z

We can now switch over to using cpu_pm instead of custom calls and make the context save and restore functions static. Let's also move the save and restore functions to avoid adding forward declarations for them. And get rid of the static data pointer while at it.

memory: omap-gpmc: Clear GPMC_CS_CONFIG7 register on restore if unused

We want to clear any unused GPMC_CS_CONFIG7 register on restore to ensure unused chip selects are not enabled. Cc: Roger Quadros Signed-off-by: Tony Lindgren Link: https://lore.kernel.org/r/20210727101034.32148-1-tony@atomide.com Signed-off-by: Krzysztof Kozlowski

Merge tag 'memory-controller-drv-tegra-5.14-2' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers

Memory controller drivers for v5.14 - Tegra SoC, part two Second set of changes for Tegra SoC memory controller drivers, containing patchset from Thierry Reding: "The goal here is to avoid early identity mappings altogether and instead postpone the need for the identity mappings to when devices are attached to the SMMU. This works by making the SMMU driver coordinate with the memory controller driver on when to start enforcing SMMU translations. This makes Tegra behave in a more standard way and pushes the code to deal with the Tegra-specific programming into the NVIDIA SMMU implementation." This pulls a dependency from Will Deacon (ARM SMMU driver) and contains further ARM SMMU driver patches to resolve complex dependencies between different patchsets. The pull from Will contains only one patch ("Implement ->probe_finalize()"). Further work in Will's tree might depend on this patch, therefore patch was applied there. On the other hand, this ("Implement ->probe_finalize()") patch is also a dependency for ARM SMMU driver changes for Tegra. These changes, bringing seamless transition from the firmware framebuffer to the OS framebuffer, depend on earlier Tegra memory controller driver patches. * tag 'memory-controller-drv-tegra-5.14-2' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl: (37 commits) iommu/arm-smmu: Use Tegra implementation on Tegra186 iommu/arm-smmu: tegra: Implement SID override programming iommu/arm-smmu: tegra: Detect number of instances at runtime dt-bindings: arm-smmu: Add Tegra186 compatible string memory: tegra: Delete dead debugfs checking code iommu/arm-smmu: Implement ->probe_finalize() memory: tegra: Implement SID override programming memory: tegra: Split Tegra194 data into separate file memory: tegra: Add memory client IDs to tables memory: tegra: Unify drivers memory: tegra: Only initialize reset controller if available memory: tegra: Make IRQ support opitonal memory: tegra: Parameterize interrupt handler memory: tegra: Extract setup code into callback memory: tegra: Make per-SoC setup more generic memory: tegra: Push suspend/resume into SoC drivers memory: tegra: Introduce struct tegra_mc_ops memory: tegra: Unify struct tegra_mc across SoC generations memory: tegra: Consolidate register fields memory: tegra30-emc: Use devm_tegra_core_dev_init_opp_table() ...

memory: pl353-smc: Let lower level controller drivers handle inits

2021-06-10T15:15:16Z

There is no point in having all these definitions at the SMC bus level, these are extremely tight to the NAND controller driver implementation, are not particularly generic, imply more boilerplate than needed, do not really follow the device model by receiving no argument and some of them are actually buggy. Let's get rid of these right now as there is no current user and keep this driver at a simple level: only the SMC bare initializations. The NAND controller driver which I am going to introduce will take care of redefining properly all these helpers and using them directly.
