* power: axp818: Add support for DLDO and ELDO regulatorsChen-Yu Tsai2016-01-26-6/+50
| | | | | | | | | AXP818 provides an array of LDOs to provide power to various peripherals. None of these regulators are critical. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* power: axp: merge separate DLDO functions into 1Chen-Yu Tsai2016-01-26-68/+20
| | | | | | | | | | | Instead of one function for each DLDO regulator, make 1 function that takes an extra "index". Since the control bits for the DLDO regulators are contiguous, this makes the function very simple. This removes a lot of duplicate code.

* | bug.h: move BUILD_BUG_* defines to include/linux/bug.hMasahiro Yamada2016-01-25-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BUILD_BUG_* macros have been defined in several headers. It would be nice to collect them in include/linux/bug.h like Linux. This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot. I'd like to postpone it until the root cause (the "error()" macro in include/common.h causes the name conflict with "__attribute__((error()))") is fixed.

* | dm: x86: spi: Convert ICH SPI driver to driver model PCI APISimon Glass2016-01-24-116/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present this SPI driver works by searching the PCI buses for its peripheral. It also uses the legacy PCI API. In addition the driver has code to determine the type of Intel PCH that is used (version 7 or version 9). Now that we have proper PCH drivers we can use those to obtain the information we need. While the device tree has a node for the SPI peripheral it is not in the right place. It should be on the PCI bus as a sub-peripheral of the LPC device. Update the device tree files to show the SPI controller within the PCH, so that PCI access works as expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | A Platform Controller Hub is an Intel concept - it is like the peripherals on an SoC and is often in a separate chip from the CPU. The chip is typically found on the first PCI bus and integrates multiple devices. We have a very simple uclass to support PCHs. Add a few operations, such as setting up the devices on the PCH and finding the SPI controller base address. Also move it into drivers/pch/ since we will be adding a few PCH drivers.

Unfortunately this driver is not fully functional. It cannot reliably read EDID information over HDMI.
