2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
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.

2023-01-12adc: stm32mp15: add calibration supportOlivier Moysan
Add support of offset and linear calibration for STM32MP15. The calibration is performed once at probe. The ADC is set in power on state for calibration. It remains in this state after calibration, to give to the kernel the opportunity to retrieve calibration data, directly from the ADC.

2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
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>
2020-08-03adc: Drop dm.h header fileSimon Glass
This header file should not be included in other header files. Remove it and use a forward declaration instead. Drop the common.h inclusion also. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2018-08-03adc: Add driver for STM32 ADCFabrice Gasnier
This patch adds support for STMicroelectronics STM32 ADC (analog to digital converter). It's originally based on Linux kernel v4.18-rcs drivers/iio/adc/stm32-adc*. It's composed of: - core driver (UCLASS_SIMPLE_BUS) manages common resources (clk, regu). - child drivers (UCLASS_ADC) declare each ADC, channels and handle conversions. This driver currently supports STM32H7 and STM32MP1 ADC. Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Reviewed-by: Simon Glass <sjg@chromium.org>
