2021-01-16power: regulator: Kconfig: add a dependency for POWER_SUPPORT for SPLNishanth Menon1-1/+1
power/regulator will not be built if just CONFIG_SPL_DM_REGULATOR is enabled. It needs CONFIG_SPL_POWER_SUPPORT to be enabled as well. For example, if we just need a GPIO regulator in SPL: CONFIG_DM_REGULATOR=y CONFIG_SPL_DM_REGULATOR=y CONFIG_DM_REGULATOR_GPIO=y CONFIG_SPL_DM_REGULATOR_GPIO=y Will not suffice, since the entire regulator build for SPL depends on CONFIG_SPL_POWER_SUPPORT. Elaborate that information in the Kconfig dependency. Signed-off-by: Nishanth Menon <nm@ti.com> Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com>

2021-01-05dm: Rename U_BOOT_DRIVER_ALIAS to DM_DRIVER_ALIASSimon Glass1-1/+1
We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but in every other case we just use DM_. Update the alias macros to use the DM_ prefix. We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro is widely used and there is at least some benefit to indicating it us a U-Boot driver, particularly for code ported from Linux. So for now, let's keep that name. Signed-off-by: Simon Glass <sjg@chromium.org>

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-07-10core: add support for U_BOOT_DRIVER_ALIASWalter Lozano1-0/+2
Currently when using OF_PLATDATA the binding between devices and drivers is done trying to match the compatible string in the node with a driver name. However, usually a single driver supports multiple compatible strings which causes that only devices which its compatible string matches a driver name get bound. To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro, which generates no code at all, but allows an easy way to declare driver name aliases. Thanks to this, dtoc could be improve to look for the driver name based on its alias when it populates the U_BOOT_DEVICE entry.

2020-07-10drivers: rename drivers to match compatible stringWalter Lozano2-4/+4
When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

There maybe an overshoot: - when disabling, then re-enabling vrefbuf too quickly - or upon platform reset as external capacitor maybe slow discharging (VREFBUF is HiZ at reset by default). VREFBUF is used by ADC/DAC on some boards. An overshoot on the reference voltage make the conversions inaccurate for a short period of time. So: - Don't put the VREFBUF in HiZ when disabling, to force an active discharge. - Enforce a 1ms OFF/ON delay, also upon reset Penalty is a 1ms delay is applied (even for a cold boot), when enabling VREFBUF.

2020-06-15regulator: fix: enable gpio when requestedMark Kettenis2-3/+2
The fix in commit b7adcdd073c0 has the side-effect that the regulator will be disabled when requesting the relevant gpio in regulator_common_ofdata_to_platdata() and enabled in regulator_pre_probe() when the regulator was already enabled. This leads to a short interruption in the 3.3V power to the PCIe slot on the firefly-rk3399 which makes an ADATA SX8000NP NVMe SSD unhappy. Fix this by setting the GPIOD_IS_OUT_ACTIVE flag again when the 'regulator-boot-on' property is set, but check for this property explicitly instead of relying on the "boot_on" member of the uclass platdata.
