2024-10-25imx: power-domain: Convert to use livetree API for fdt accessTim Harvey
Convert to using livetree API functions. Without this if livetree is enabled (OF_LIVE) the imx8m-power-domain driver will (silently) fail to probe its children leaving you with no power domain support causing issues with certain devices.

This switches all boards with the Allwinner H616/H618/H313/H700 SoCs over to use OF_UPSTREAM. We are doing it for this SoC family only since the DTs between the U-Boot and the kernel repo are exactly identical, whereas other families have one compatibility fix in U-Boot to allow booting older kernels. Other will follow if this plays out well. The biggest chunk otherwise is adding support for an Anbernic game console, using the H700 SoC. For that we need to enhance the DRAM support code, and pick two DT commits from the mainline kernel/DT rebasing repo, followed by the defconfig patch. On top of that two small fixes for the old Allwinner A80. Gitlab CI passed, and I booted that briefly on some boards, including an H616 and an H618 one (with LPDDR4).
2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <[email protected]> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.

2024-10-10sunxi: power: axp809: Fix DCDC4 programmingAndre Przywara
When trying to set the DCDC4 regulator, the code was accidentally setting the voltage register for DCDC5 (VCC-DRAM). The higher voltage doesn't harm the DRAM chips, but upsets the Linux regulator driver: when it tried to correct that, it tripped over a separate DT bug. The DCDC5 DT limits are 1.425 and 1.575V, which cannot bet set with the rail's resolution of 50mV. The kernel driver gave up, and made in turn the system hang, as the PMIC powers essential devices. Fix the copy&paste bug by using the correct PMIC voltage register. Signed-off-by: Andre Przywara <[email protected]>

regulator_post_probe Turn regulators_enable_boot_on() and regulators_enable_boot_off() into empty functions. Implement matching functionality in regulator_post_probe() instead. The regulator_post_probe() is called for all regulators after they probe, and regulators that have regulator-always-on or regulator-boot-on DT properties now always probe due to DM_FLAG_PROBE_AFTER_BIND being set on such regulators in regulator_post_bind().

Unconditionally probe such regulator drivers. This is a preparatory patch for introduction of .regulator_post_probe() which would trigger the regulator configuration. Parsing of regulator-always-on and regulator-boot-on DT property has been moved to regulator_post_bind() as the information is required early, the rest of the DT parsing has been kept in regulator_pre_probe() to avoid slowing down the boot process.

2024-09-25power: regulator: Do not call set_suspend_value with -ENODATAJonas Karlman
On some boards a PMIC regulator is flagged with regulator-on-in-suspend and does not define any suspend or max microvolt, e.g. on Radxa ROCK 3A: vcc_ddr: DCDC_REG3 { regulator-name = "vcc_ddr"; regulator-always-on; regulator-boot-on; regulator-initial-mode = <0x2>; regulator-state-mem { regulator-on-in-suspend; }; }; This result in suspend_uV having the value -ENODATA after probe. This negative voltage, -ENODATA, gets missinterpreted and result in an unexpected voltage being set by autoset. E.g. on Radxa ROCK 3A the vcc_ddr regulator by default have a normal and suspend voltage value of 0.5v. However, due to this missinterpretation the suspend voltage end up beind set to 0.5625v instead. Fix this by skip calling regulator_set_suspend_value() in autoset and also protect calling set value ops when input value is -ENODATA. Signed-off-by: Jonas Karlman <[email protected]>

2024-07-15power: pmic: sunxi: introduce generic SPL AXP DC/DC driverAndre Przywara
So far we had a separate driver file for each AXP PMIC chip that we need to support in the SPL. The code in there was largely similar, but differed in many details. Based on the idea of the DM AXP driver, introduce a data structure to describe each regulator in a compact way. This is a simplified version of the struct used in the DM driver, as we don't need to support the full voltage range and not every regulator in the SPL. For now we only support the DC/DC buck converters, since that's what we need the SPL to configure, mostly. Also we get rid of the regulator name, and hardcode the regulator number by its position in the array (first is DCDC1, second is DCDC2, etc). We also drop support for the value table, we ideally won't need that for the subset of regulators required. At the end each regulator is described by a 10 bytes struct, so we avoid blowing up the SPL footprint, but still can use generic code. Each chip is supposed to be described separately, and protected by ifdef's, to only build in the regulators needed for a particular board. We also describe the bits to help identifying the AXP chip, and the shutdown details in that section. Add a generic driver, that exports axp_set_dcdc<x>() functions to set up the buck converters. For now this just contains the bits for the (new) AXP717, but it's not wired up anywhere yet. Signed-off-by: Andre Przywara <[email protected]>

The AXP221 driver defines axp_get_sid(), which is used in the U-Boot proper cpuinfo() code, and some old LCD code directly calls axp_set_eldo(), so we keep that driver outside the new guards. This will be fixed properly later. Signed-off-by: Andre Przywara <[email protected]>
