Add a mailbox driver framework/uclass

2016-05-27T02:48:31Z

A mailbox is a hardware mechanism for transferring small message and/or notifications between the CPU on which U-Boot runs and some other device such as an auxilliary CPU running firmware or a hardware module. This patch defines a standard API that connects mailbox clients to mailbox providers (drivers). Initially, DT is the only supported method for connecting the two. The DT binding specification (mailbox.txt) was taken from Linux kernel v4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt. Signed-off-by: Stephen Warren Acked-by: Simon Glass

dm: mmc: spl: Use the legacy block interface in SPL

2016-05-17T15:54:43Z

Bring this in for SPL so that we can use generic code for loading from block devices. Signed-off-by: Simon Glass

2016-05-17T15:54:43Z

This function is implemented by the legacy block functions now. Drop it. Signed-off-by: Simon Glass

drivers: Add SPMI bus uclass

2016-04-01T21:18:12Z

Qualcom processors use proprietary bus to talk with PMIC devices - SPMI (System Power Management Interface). On wiring level it is similar to I2C, but on protocol level, it's multi-master and has simple autodetection capabilities. This commit adds simple uclass that provides bus read/write interface.

dm: Expand the uclass for Platform Controller Hubs (PCH)

2016-01-24T04:07:17Z

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.

arm: mvebu: Move SoC selection (A38X vs AXP) into Kconfig

2016-01-14T13:08:59Z

Until now, the SoC selection for the ARCH_MVEBU platforms has been done in the config header. Using CONFIG_ARMADA_XP in a non-clear way. As it needed to get selected for AXP and A38x based boards. This patch now changes this to move the SoC selection to Kconfig. And also uses CONFIG_ARCH_MVEBU as a common define for both AXP and A38x. This makes things a bit clearer - especially for new board additions. Additionally the defines CONFIG_SYS_MVEBU_DDR_AXP and CONFIG_SYS_MVEBU_DDR_A38X are replaced with the already available CONFIG_ARMADA_38X and CONFIG_ARMADA_XP. And CONFIG_DDR3 is removed, as its not referenced anywhere. Signed-off-by: Stefan Roese Cc: Luka Perkov

Various Makefiles: Add SPDX-License-Identifier tags

2015-11-10T14:19:52Z

After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag. Cc: Kate Stewart Signed-off-by: Tom Rini

dm: adc: add simple ADC uclass implementation

This commit adds: - new uclass id: UCLASS_ADC - new uclass driver: drivers/adc/adc-uclass.c The new uclass's API allows for ADC operation on: * single-channel with channel selection by a number * multti-channel with channel selection by bit mask ADC uclass's functions: * single-channel: - adc_start_channel() - start channel conversion - adc_channel_data() - get conversion data - adc_channel_single_shot() - start/get conversion data * multi-channel: - adc_start_channels() - start selected channels conversion - adc_channels_data() - get conversion data - adc_channels_single_shot() - start/get conversion data for channels selected by bit mask * general: - adc_stop() - stop the conversion - adc_vdd_value() - positive reference Voltage value with polarity [uV] - adc_vss_value() - negative reference Voltage value with polarity [uV] - adc_data_mask() - conversion data bit mask The device tree can provide below constraints/properties: - vdd-polarity-negative: if true: Vdd = vdd-microvolts * (-1) - vss-polarity-negative: if true: Vss = vss-microvolts * (-1) - vdd-supply: phandle to Vdd regulator's node - vss-supply: phandle to Vss regulator's node And optional, checked only if the above corresponding, doesn't exist: - vdd-microvolts: positive reference Voltage [uV] - vss-microvolts: negative reference Voltage [uV] Signed-off-by: Przemyslaw Marczak Cc: Simon Glass Signed-off-by: Minkyu Kang
