2025-06-27ARM: OMAP2+: Fix l4ls clk domain handling in STANDBYSukrut Bellary
[ Upstream commit 47fe74098f3dadba2f9cc1e507d813a4aa93f5f3 ] Don't put the l4ls clk domain to sleep in case of standby. Since CM3 PM FW[1](ti-v4.1.y) doesn't wake-up/enable the l4ls clk domain upon wake-up, CM3 PM FW fails to wake-up the MPU.

2025-06-27ARM: omap: pmic-cpcap: do not mess around without CPCAP or OMAP4Andreas Kemnade
commit 7397daf1029d5bfd3415ec8622f5179603d5702d upstream. The late init call just writes to omap4 registers as soon as CONFIG_MFD_CPCAP is enabled without checking whether the cpcap driver is actually there or the SoC is indeed an OMAP4. Rather do these things only with the right device combination. Fixes booting the BT200 with said configuration enabled and non-factory X-Loader and probably also some surprising behavior on other devices.

commit 96e0b355883006554a0bee3697da475971d6bba8 upstream. arm/memremap: fix arch_memremap_can_ram_remap() commit 260364d112bc ("arm[64]/memremap: don't abuse pfn_valid() to ensure presence of linear map") added the definition of arch_memremap_can_ram_remap() for arm[64] specific filtering of what pages can be used from the linear mapping. memblock_is_map_memory() was called with the pfn of the address given to arch_memremap_can_ram_remap(); however, memblock_is_map_memory() expects to be given an address for arm, not a pfn. This results in calls to memremap() returning a newly mapped area when it should return an address in the existing linear mapping. Fix this by removing the address to pfn translation and pass the address directly.

2025-05-29ARM: at91: pm: fix at91_suspend_finish for ZQ calibrationLi Bin
[ Upstream commit bc4722c3598d0e2c2dbf9609a3d3198993093e2b ] For sama7g5 and sama7d65 backup mode, we encountered a "ZQ calibrate error" during recalibrating the impedance in BootStrap. We found that the impedance value saved in at91_suspend_finish() before the DDR entered self-refresh mode did not match the resistor values. The ZDATA field in the DDR3PHY_ZQ0CR0 register uses a modified gray code to select the different impedance setting. But these gray code are incorrect, a workaournd from design team fixed the bug in the calibration logic. The ZDATA contains four independent impedance elements, but the algorithm combined the four elements into one. The elements were fixed using properly shifted offsets.

2025-05-02crypto: lib/Kconfig - Hide arch options from userHerbert Xu
commit 17ec3e71ba797cdb62164fea9532c81b60f47167 upstream. The ARCH_MAY_HAVE patch missed arm64, mips and s390. But it may also lead to arch options being enabled but ineffective because of modular/built-in conflicts. As the primary user of all these options wireguard is selecting the arch options anyway, make the same selections at the lib/crypto option level and hide the arch options from the user. Instead of selecting them centrally from lib/crypto, simply set the default of each arch option as suggested by Eric Biggers. Change the Crypto API generic algorithms to select the top-level lib/crypto options instead of the generic one as otherwise there is no way to enable the arch options (Eric Biggers). Introduce a set of INTERNAL options to work around dependency cycles on the CONFIG_CRYPTO symbol.

2025-04-10ARM: 9443/1: Require linker to support KEEP within OVERLAY for DCENathan Chancellor
commit e7607f7d6d81af71dcc5171278aadccc94d277cd upstream. ld.lld prior to 21.0.0 does not support using the KEEP keyword within an overlay description, which may be needed to avoid discarding necessary sections within an overlay with '--gc-sections', which can be enabled for the kernel via CONFIG_LD_DEAD_CODE_DATA_ELIMINATION. Disallow CONFIG_LD_DEAD_CODE_DATA_ELIMINATION without support for KEEP within OVERLAY and introduce a macro, OVERLAY_KEEP, that can be used to conditionally add KEEP when it is properly supported to avoid breaking old versions of ld.lld.

commit 83964a29379cb08929a39172780a4c2992bc7c93 upstream. The current solution for powering off the Apalis iMX6 is not functioning as intended. To resolve this, it is necessary to power off the vgen2_reg, which will also set the POWER_ENABLE_MOCI signal to a low state. This ensures the carrier board is properly informed to initiate its power-off sequence. The new solution uses the regulator-poweroff driver, which will power off the regulator during a system shutdown.

2025-02-17ARM: dts: ti/omap: gta04: fix pm issues caused by spi moduleAndreas Kemnade
commit 0cfbd7805fe13406500e6a6f2aa08f198d5db4bd upstream. Despite CM_IDLEST1_CORE and CM_FCLKEN1_CORE behaving normal, disabling SPI leads to messages like when suspending: Powerdomain (core_pwrdm) didn't enter target state 0 and according to /sys/kernel/debug/pm_debug/count off state is not entered. That was not connected to SPI during the discussion of disabling SPI. See: https://lore.kernel.org/linux-omap/20230122100852.32ae082c@aktux/ The reason is that SPI is per default in slave mode. Linux driver will turn it to master per default. It slave mode, the powerdomain seems to be kept active if active chip select input is sensed. Fix that by explicitly disabling the SPI3 pins which used to be muxed by the bootloader since they are available on an optionally fitted header which would require dtb overlays anyways.

2025-02-17ARM: dts: dra7: Add bus_dma_limit for l4 cfg busRomain Naour
commit c1472ec1dc4419d0bae663c1a1e6cb98dc7881ad upstream. A bus_dma_limit was added for l3 bus by commit cfb5d65f2595 ("ARM: dts: dra7: Add bus_dma_limit for L3 bus") to fix an issue observed only with SATA on DRA7-EVM with 4GB RAM and CONFIG_ARM_LPAE enabled. Since kernel 5.13, the SATA issue can be reproduced again following the SATA node move from L3 bus to L4_cfg in commit 8af15365a368 ("ARM: dts: Configure interconnect target module for dra7 sata"). Fix it by adding an empty dma-ranges property to l4_cfg and segment@100000 nodes (parent device tree node of SATA controller) to inherit the 2GB dma ranges limit from l3 bus node. Note: A similar fix was applied for PCIe controller by commit 90d4d3f4ea45 ("ARM: dts: dra7: Fix bus_dma_limit for PCIe"). Fixes: 8af15365a368 ("ARM: dts: Configure interconnect target module for dra7 sata").

commit 96a64e9730c2c76cfa5c510583a0fbf40d62886b upstream. Operating stable without reduced chip life at 1Ghz needs several technologies working: The technologies involve - SmartReflex - DVFS As this cannot directly specified in the OPP table as dependecies in the devicetree yet, use the turbo flag again to mark this OPP as something special to have some kind of opt-in. So revert commit 5f1bf7ae8481 ("ARM: dts: omap36xx: Remove turbo mode for 1GHz variants") Practical reasoning: At least the GTA04A5 (DM3730) has become unstable with that OPP enabled. Furthermore nothing enforces the availability of said technologies, even in the kernel configuration, so allow users to rather opt-in.

Hence save the physical address when it is known at boot time when calling early_init_dt_scan for arm64 and use it at kexec time instead of converting the virtual address using __pa().

2024-12-05ARM: dts: cubieboard4: Fix DCDC5 regulator constraintsAndre Przywara
[ Upstream commit dd36ad71ad65968f97630808bc8d605c929b128e ] The DCDC5 voltage rail in the X-Powers AXP809 PMIC has a resolution of 50mV, so the currently enforced limits of 1.475 and 1.525 volts cannot be set, when the existing regulator value is beyond this range. This will lead to the whole regulator driver to give up and fail probing, which in turn will hang the system, as essential devices depend on the PMIC. In this case a bug in U-Boot set the voltage to 1.75V (meant for DCDC4), and the AXP driver's attempt to correct this lead to this error: ================== [ 4.447653] axp20x-rsb sunxi-rsb-3a3: AXP20X driver loaded [ 4.450066] vcc-dram: Bringing 1750000uV into 1575000-1575000uV [ 4.460272] vcc-dram: failed to apply 1575000-1575000uV constraint: -EINVAL [ 4.474788] axp20x-regulator axp20x-regulator.0: Failed to register dcdc5 [ 4.482276] axp20x-regulator axp20x-regulator.0: probe with driver axp20x-regulator failed with error -22 ================== Set the limits to values that can be programmed, so any correction will be successful.

2024-12-05ARM: dts: microchip: sam9x60: Add missing property atmel,usart-modeAndrei Simion
[ Upstream commit 2f9d013a0c6f1b9109ada5acb28ee26eefc77c03 ] Add the atmel,usart-mode property to the UART nodes. This ensures compliance with the atmel,at91-usart.yaml schema and resolves the errors below: serial@200: $nodename:0: 'serial@200' does not match '^spi(@.*|-([0-9]|[1-9][0-9]+))?$' serial@200: atmel,use-dma-rx: False schema does not allow True serial@200: atmel,use-dma-tx: False schema does not allow True serial@200: atmel,fifo-size: False schema does not allow [[16]] These errors indicate that the property atmel,usart-mode = <AT91_USART_MODE_SERIAL> is missing for UART nodes 0, 1, 2, 3, 4, 6, 7, 8, 9, 10, 11, and 12.
