2018-02-03log: Add a way to log error-return valuesSimon Glass
When functions return an error it propagates up the stack to the point where it is reported. Often the error code provides enough information about the root cause of the error that this is obvious what went wrong. However in some cases the error may be hard to trace. For example if a driver uses several devices to perform an operation, it may not be obvious which one failed. Add a log_ret() macro to help with this. This can be used to wrap any error-return value. The logging system will then output a log record when the original error is generated, making it easy to trace the call stack of the error. This macro can significantly impact code size, so its use is controlled by a Kconfig option, which is enabled for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>

2017-12-12power: extend prefix match to regulator-name propertyFelix Brack
This patch extends pmic_bind_children prefix matching. In addition to the node name the property regulator-name is used while trying to match prefixes. This allows assigning different drivers to regulator nodes named regulator@1 and regulator@10 for example. I have discarded the idea of using other properties then regulator-name as I do not see any benefit in using property compatible or even regulator-compatible. Of course I am open to change this if there are good reasons to do so. Signed-off-by: Felix Brack <fb@ltec.ch> Reviewed-by: Simon Glass <sjg@chromium.org>

The reset circuitry in the RK3399 only resets 'almost all logic' when a software reset is performed. To make our software maintenance easier in the future, we want to have the option (controlled by a DTS property) to force all reset causes other than a power-on reset to trigger a power-on reset via a GPIO trigger. This adds the necessary support to the rk3399-puma (i.e. RK3399-Q7) board-support and the documentation for the new property (sysreset-gpio) within the /config-node.

2017-11-21rockchip: rk3188: use boot0 hook to load up SPL in 2 stepsPhilipp Tomsich
For the RK3188, the BROM will attempt to load up the first stage image (SPL for the RK3188) in two steps: first 1KB to offset 0x800 in the SRAM and then the remainder to offset 0xc00 in the SRAM. It always enters at 0x804, though. With this changeset, the RK3188 boot removes the TPL (stub) stage and builds a single SPL binary that utilizes the early back-to-bootrom via the boot0-hook. Consequently, the passing of the saved boot params via pmu->os_reg[2] is also removed. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
