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.

SARADC v1 and v2 have a different way of starting a channel, therefore
let's abstract this function so that it can be provided from the

rockchip: adc: rockchip-saradc: use union for preparing for v2

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

The registers are entirely different between SARADC v1 and SARADC v2, so
let's prepare to add another struct for accessing v2 registers by adding
a union.

dm: adc: imx93-adc depends on ADC (fix boot)

2023-10-18T08:02:49+00:00

The i.MX93 11x11 EVK fails to boot with following error:

 Model: NXP i.MX93 11X11 EVK board
 DRAM:  2 GiB
 Error binding driver 'imx93-adc': -96
 Some drivers failed to bind
 Error binding driver 'simple_bus': -96

 Error binding driver 'simple_bus': -96
 Some drivers failed to bind
 initcall sequence 00000000fffb8f28 failed at call 000000008021e0d4 (err=-96)
 ### ERROR ### Please RESET the board ###

That's because since commit e7ff54d96303 ("imx93_evk: defconfig: add adc
support") CONFIG_ADC_IMX93 is enabled but CONFIG_ADC is not.
Fix this by enabling CONFIG_ADC in imx93_11x11_evk_defconfig.

Make sure this situation won't happen again in future i.MX93 defconfig by
making CONFIG_ADC_IMX93 depend on CONFIG_ADC.
