2018-05-07regmap: change regmap_init_mem() to take ofnode instead udeviceMasahiro Yamada
Currently, regmap_init_mem() takes a udevice. This requires the node has already been associated with a device. It prevents syscon/regmap from behaving like those in Linux. Change the first argumenet to take a device node.

2018-05-07SPDX: Convert all of our multiple 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 multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.

With the new 32/64bit-aware dtoc, the type of reg is fdt64_t and the OF_PLATDATA structure layout changes. This adjusts the DMC driver for the RK3368 to track these changes.

2017-08-13rockchip: rk3368: add DRAM controller driver with DRAM initialisationPhilipp Tomsich
This adds a DRAM controller driver for the RK3368 and places it in drivers/ram/rockchip (where the other DM-enabled DRAM controller drivers for rockchip devices should also be moved eventually). At this stage, only the following feature-set is supported: - DDR3 - 32-bit configuration (i.e. fully populated) - dual-rank (i.e. no auto-detection of ranks) - DDR3-1600K speed-bin This driver expects to run from a TPL stage that will later return to the RK3368 BROM. It communicates with later stages through the os_reg2 in the pmugrf (i.e. using the same mechanism as Rockchip's DDR init code). Unlike other DMC drivers for RK32xx and RK33xx parts, the required timings are calculated within the driver based on a target frequency and a DDR3 speed-bin (only the DDR3-1600K speed-bin is support at this time). The RK3368 also has the DDRC0_CON0 (DDR ch. 0, control-register 0) register for controlling the operation of its (single-channel) DRAM controller in the GRF block. This provides for selecting DDR3, mobile DDR modes, and control low-power operation. As part of this change, DDRC0_CON0 is also added to the GRF structure definition (at offset 0x600).

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.
