adc: rockchip-saradc: Use vdd-microvolts prop as fallback

2024-10-26T02:46:48+00:00

Change to use vdd-microvolts prop value as voltage reference when the
supply regulator is missing or when DM_REGULATOR=n is used.

adc: Allow use of adc with DM_REGULATOR disabled

2024-10-26T02:46:48+00:00

When DM_REGULATOR=n is used the device_get_supply_regulator() function
always return -ENOSYS.

Change to treat missing support for regulators as a missing optional
vdd/vss-supply regulator to reduce error messages being logged.

global: Rename SPL_TPL_ to PHASE_

2024-10-11T17:44:48+00:00

Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.

Update the comment in bootstage to refer to this symbol, instead of
SPL_

dm: adc: Add SPL_ADC Kconfig symbol for use of ADC in SPL

2024-08-09T10:35:23+00:00

What model of Radxa ZERO 3W/3E board can be identified using ADC at
runtime, add a Kconfig symbol to allow use of ADC in SPL.

This will be used to identify board model in SPL to allow loading
correct FIT configuration and FDT for U-Boot proper at SPL phase.

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

2024-05-19T14:16:36+00:00

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.

adc: add missing depends on ADC for controller drivers

2024-03-14T10:20:04+00:00

The ADC controller drivers are obviously all depending on ADC symbol
being selected.

While they don't seem to fail to build without, they won't be useful
without that symbol selected, so let's make sure the options aren't
shown in menuconfig when ADC isn't selected.

rockchip: adc: rockchip-saradc: add support for RK3588

2024-03-14T10:19:44+00:00

This adds support for the SARADCv2 found on RK3588.

There is no stop callback as it is currently configured in single
conversion mode, where the ADC is powered down after a single conversion
has been made.

Due to what seems to be a silicon bug, a controller reset needs to be
issued before starting a channel conversion otherwise Rockchip says that
channel 1 will error whatever that means. This is aligned with upstream
and downstream Linux kernel as well as downstream U-Boot.

rockchip: adc: rockchip-saradc: factor out stop callback

2024-03-14T10:19:44+00:00

SARADC v2 doesn't have a stop mechanism once in single mode. In series
conversion, the logic is different anyway. Therefore, let's abstract
this function so that it can be provided from the udevice.data pointer.
