Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

power: axp: Avoid do_poweroff conflict with sysreset

2021-10-25T13:50:54Z

The sysreset uclass has an option to provide the do_poweroff() function. When that option is enabled, the AXP power drivers should not provide their own definition. For the AXP305, which is paired with 64-bit systems where TF-A provides PSCI, there is another possible conflict with the PSCI firmware driver. This driver can be enabled even if CONFIG_PSCI_RESET is disabled, so make sure to use the right symbol in the condition.

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55Z

We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass

power: axp209: Limit inrush current for broken boards

2018-12-07T16:54:33Z

Some boards feature a capacitance on LDO3's output that is too large, causing inrush currents which as a result, shut down the AXP209. This has been reported before, without knowing the actual cause. A fix appeared to be done with commit 0e6e34ac8dbb ("sunxi: Olimex A20 boards: Enable LDO3 and LDO4 regulators"). The description there is a bit misleading, the kernel does not hang during AXP209 initialization, the PMIC shuts down, causing voltages to drop and thus the whole system freezes. While the AXP209 does have the ability to ramp up the voltage slowly, to reduce these inrush currents, the voltage rate control (VRC) however is not applicable when switching on the LDO3 output. Only when going from an enabled lower voltage setting, to a higher voltage setting is the VRC in effect. To work around this problem, we set LDO3 to the lowest possible setting of 0.7 V if it was not yet enabled, and then let the VRC (if enabled) do its thing. It should be noted, that for some undocumented reason, there is a short delay needed between setting the LDO3 voltage register and enabling the power. One would expect that this delay ought to be just after enabling the output power at 0.7 V, but this did not work. Signed-off-by: Olliver Schinagl Signed-off-by: Priit Laes Acked-by: Maxime Ripard

power: axp209: Add support for voltage rate control on LDO3

2018-12-07T16:54:33Z

The AXP209 LDO3 regulator supports voltage rate control, or can set a slew rate. This allows for the power to gradually rise up to the desired voltage, instead of spiking up as fast as possible. Reason to have this can be to reduce the inrush currents for example. There are 3 slopes to choose from, the default, 'none' is a voltage rise of 0.0167 V/uS, a 1.6 mV/uS and a 0.8 mV/uS voltage rise. In ideal world (where vendors follow the recommended design guidelines) this setting should not be enabled by default. Unless of course AXP209 crashes instead of reporting overcurrent condition as it normally should do in this case. Signed-off-by: Olliver Schinagl Signed-off-by: Priit Laes Acked-by: Maxime Ripard
