2025-01-17cpufreq: Use str_enable_disable()-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

Qualcomm regulator supports two power supply modes: HPM and LPM. Currently, the sdhci-msm.c driver does not set the load to adjust the current for eMMC and SD. If the regulator dont't set correct load in LPM state, it will lead to the inability to properly initialize eMMC and SD.

2025-01-17pmdomain: arm: scmi_pm_domain: Send an explicit request to set the current stateSudeep Holla
On a system with multiple active SCMI agents, one agent(other than OSPM/ Linux or bootloader) would request to turn on a shared power domain before the Linux boots/initialise the genpds. So when the Linux boots and gets the power state as already ON, it just registers the genpd with a default ON state. However, when the driver that needs this shared power domain is probed genpd sees that the power domain status is ON and never makes any SCMI call to power it up which is correct. But, since Linux didn't make an explicit request to turn on the shared power domain, the SCMI platform firmware will not know if the OSPM agent is actively using it. Suppose the other agent that requested the shared power domain to be powered ON requests to power it OFF as it no longer needs it, the SCMI platform firmware needs to turn it off if there are no active users of it which in the above scenaro is the case. As a result of SCMI platform firmware turning off the resource, OSPM/ Linux will crash the moment as it expects the shared power domain to be powered ON. Send an explicit request to set the current state when setting up the genpd power domains so that OSPM registers its vote in the power domain state with the SCMI platform firmware. The other option is to not read the state and set the genpds as default OFF, but it can't handle the scenario on certain platforms where SCMI platform keeps all the power domains turned ON by default for faster boot (or any other such variations) and expect the OSPM to turn off the unused domains if power saving is required.

2025-01-17iommu/amd: Remove domain_alloc()Jason Gunthorpe
IOMMU drivers should not be sensitive to the domain type, a paging domain should be created based only on the flags passed in, the same for all callers. AMD was using the domain_alloc() path to force VFIO into a v1 domain type, because v1 gives higher performance. However now that IOMMU_HWPT_ALLOC_PASID is present, and a NULL device is not possible, domain_alloc_paging_flags() will do the right thing for VFIO. When invoked from VFIO flags will be 0 and the amd_iommu_pgtable type of domain will be selected. This is v1 by default unless the kernel command line has overridden it to v2. If the admin is forcing v2 assume they know what they are doing so force it everywhere, including for VFIO.

Add simple CPU Freq driver for Airoha EN7581 SoC that control CPU frequency scaling with SMC APIs and register a generic "cpufreq-dt" device. All CPU share the same frequency and can't be controlled independently. CPU frequency is controlled by the attached PM domain. Add SoC compatible to cpufreq-dt-plat block list as a dedicated cpufreq driver is needed with OPP v2 nodes declared in DTS.

2025-01-16net: stmmac: convert to phylink managed EEE supportRussell King (Oracle)
Convert stmmac to use phylink managed EEE support rather than delving into phylib: 1. Move the stmmac_eee_init() calls out of mac_link_down() and mac_link_up() methods into the new mac_{enable,disable}_lpi() methods. We leave the calls to stmmac_set_eee_pls() in place as these change bits which tell the EEE hardware when the link came up or down, and is used for a separate hardware timer. However, symmetrically conditionalise this with priv->dma_cap.eee. 2. Update the current LPI timer each time LPI is enabled - which we need for software-timed LPI. 3. With phylink managed EEE, phylink manages the receive clock stop configuration via phylink_config.eee_rx_clk_stop_enable. Set this appropriately which makes the call to phy_eee_rx_clock_stop() redundant. 4. From what I can work out, all supported interfaces support LPI signalling on stmmac (there's no restriction implemented.) It also appears to support LPI at all full duplex speeds at or over 100M. Set these capabilities. 5. The default timer appears to be derived from a module parameter. Set this the same, although we keep code that reconfigures the timer in stmmac_init_phy(). 6. Remove the direct call to phy_support_eee(), which phylink will do on the drivers behalf if phylink_config.eee_enabled_default is set.

2025-01-16net: mvpp2: add EEE implementationRussell King (Oracle)
Add EEE support for mvpp2, using phylink's EEE implementation, which means we just need to implement the two methods for LPI control, and with the initial configuration. Only SGMII mode is supported, so only 100M and 1G speeds. Disabling LPI requires clearing a single bit. Enabling LPI needs a full configuration of several values, as the timer values are dependent on the MAC operating speed.

2025-01-16net: mvneta: convert to phylink EEE implementationRussell King (Oracle)
Convert mvneta to use phylink's EEE implementation by implementing the two LPI control methods, and adding the initial configuration and capabilities. Although disabling LPI requires clearing a single bit, for safety we clear the manual mode and force bits to ensure that auto mode will be used. Enabling LPI needs a full configuration of several values, as the timer values are dependent on the MAC operating speed, as per the original code. As Armada 388 states that EEE is only supported in "SGMII" modes, mark this in lpi_interfaces. Testing with RGMII on the Clearfog platform indicates that the receive path fails to detect LPI over RGMII.

2025-01-16net: phylink: add EEE managementRussell King (Oracle)
Add EEE management to phylink, making use of the phylib implementation. This will only be used where a MAC driver populates the methods and capabilities bitfield, otherwise we keep our old behaviour. Phylink will keep track of the EEE configuration, including the clock stop abilities at each end of the MAC to PHY link, programming the PHY appropriately and preserving the LPI configuration should the PHY go away. Phylink will call into the MAC driver when LPI needs to be enabled or disabled, with the requirement that the MAC have LPI disabled prior to the netdev being brought up (in other words, it will only call mac_disable_tx_lpi() if it has already called mac_enable_tx_lpi().) Support for phylink managed EEE is enabled by populating both tx_lpi MAC operations method pointers, and filling in both LPI interfaces and capabilities. If the methods are provided but the LPI interfaces or capabilities remain empty, this indicates to phylink that EEE is implemented by the driver but the hardware it is driving does not support EEE, and thus the ethtool set_eee() and get_eee() methods will return EOPNOTSUPP. No validation of the LPI timer value is performed by this patch. For interface modes which do not support LPI, we make no attempt to manipulate the phylib EEE advertisement, but instead refuse to activate LPI at the MAC, noting it at debug message level. We also restrict the advertisement and reported userspace support linkmode masks according to the lpi_capabilities provided to phylink by the MAC driver.
