2020-05-18common: Drop linux/bitops.h from common headerSimon Glass
Move this uncommon header out of the common header. 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>
