2019-12-15dm: gpio: Allow control of GPIO uclass in SPLSimon Glass
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed).

2019-02-11pcie: designware: mvebu: fix reset release polarityBaruch Siach
The dm_gpio_set_value() routine sets signal logical level, with GPIO_ACTIVE_LOW/HIGH value taken into account. Reset active value is 1 (asserted), while reset inactive value is 0 (de-asserted). Fix the reset toggle code to set the correct reset logic value.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-03-30dm: pcie: designware: add correct ATU handlingIgal Liberman
Currently, ATU (address translation unit) implementation doesn't support translate addresses > 32 bits. This patch allows to configure ATU correctly for different memory accesses (memory, configuration and IO). The same approach is used in Linux Kernel.

2017-11-17dm: pci: change bus number register setting compliant with LinuxMinghuan Lian
This patch is to change U-Boot PCI bus assignement compliant with Linux. It means each PCIe controller's bus number is 0, not the current maximum PCI bus number, when start to scan this controller.

2017-06-01dm: Rename dev_addr..() functionsSimon Glass
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

2017-05-09fix: mvebu: pcie_dw: Allow probing empty PCIe slotsKonstantin Porotchkin
This patch allows probing all PCIe nodes defined in DTS even if there no device connected to such node (no link). Without this fix the driver returns -ENODEV when the PCIe link is down. As result the pci_init function stops scanning bus on first empty PCIe slot and all devices located in higher numbered buses are not discovered.

This patch adds a driver for the PCIe controller integrated in the Marvell Armada-8K SoC. This controller is based on the DesignWare IP core. The original version was written by Shadi and Yehuda. I ported this driver to the latest mainline U-Boot version with DM support. Tested on the Marvell DB-88F8040 Armada-8K eval board.
