| * | include: <io.h>: define (read|write)[bwlq]_relaxed | Ahmad Fatoum | 2021-06-11 | 1 | -3/+1 |
| | | | | | | | | | | | | | | | For Linux, It's always correct to substitute any of the read or write _relaxed functions with their non relaxed counterpart. Define functions that do this. Unlike with Linux, they doesn't per se affect performance: barebox writel doesn't imply memory barriers, instead it depends on the architecture support to map IO memory regions as non-bufferable.

| * | regulator: add driver for stm32-vrefbuf | Ahmad Fatoum | 2021-02-10 | 1 | -0/+220 |
| This driver supports STMicroelectronics STM32 VREFBUF (voltage reference buffer) which can be used as voltage reference for internal ADCs, DACs and also for external components through dedicated Vref+ pin. Ported from Linux v5.11-rc1. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> | |||||
