regmap: change regmap_init_mem() to take ofnode instead udevice

2018-05-07T19:49:51Z

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. Signed-off-by: Masahiro Yamada Acked-by: Neil Armstrong Reviewed-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

aspeed: Refactor SCU to use consistent mask & shift

2017-05-08T15:57:35Z

Refactor SCU header to use consistent Mask & Shift values. Now, consistently, to read value from SCU register, mask needs to be applied before shift. Signed-off-by: Maxim Sloyko Reviewed-by: Simon Glass

aspeed: Refactor AST2500 RAM Driver and Sysreset Driver

2017-05-08T15:57:32Z

This change switches all existing users of ast2500 Watchdog to Driver Model based Watchdog driver. To perform system reset Sysreset Driver uses first Watchdog device found via uclass_first_device call. Since the system is going to be reset anyway it does not make much difference which watchdog is used. Instead of using Watchdog to reset itself, SDRAM driver now uses Reset driver to do that. These were the only users of the old Watchdog API, so that API is removed. This all is done in one change to avoid having to maintain dual API for watchdog in between.

aspeed: Make SCU lock/unlock functions part of SCU API

2017-05-08T15:57:31Z

Make functions for locking and unlocking SCU part of SCU API. Many drivers need to modify settings in SCU and thus need to unlock it first. This change makes it possible. Signed-off-by: Maxim Sloyko Reviewed-by: Simon Glass

aspeed: Watchdog Timer Driver

2017-05-08T15:57:31Z

This driver supports ast2500 and ast2400 SoCs. Only ast2500 supports reset_mask and thus the option of resettting individual peripherals using WDT. Signed-off-by: Maxim Sloyko Reviewed-by: Simon Glass

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14Z

At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function. Signed-off-by: Simon Glass

aspeed: Add basic ast2500-specific drivers and configuration

2017-01-28T19:04:29Z

Clock Driver This driver is ast2500-specific and is not compatible with earlier versions of this chip. The differences are not that big, but they are in somewhat random places, so making it compatible with ast2400 is not worth the effort at the moment. SDRAM MC driver The driver is very ast2500-specific and is completely incompatible with previous versions of the chip. The memory controller is very poorly documented by Aspeed in the datasheet, with any mention of the whole range of registers missing. The initialization procedure has been basically taken from Aspeed SDK, where it is implemented in assembly. Here it is rewritten in C, with very limited understanding of what exactly it is doing.
