2019-11-17rockchip: clk: fix wrong CONFIG_IS_ENABLED handlingHeiko Stuebner
CONFIG_IS_ENABLED() needs the config name like used in Kconfig, so without the leading CONFIG_. The clock drivers all wrongly check for CONFIG_RESET_ROCKCHIP, fix that Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>

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>

We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-03-28rockchip: clk: rk3188: update dpll settings to make EMAC workAlexander Kochetkov
The patch set dpll settings for 300MHz to values used by binary blob[1]. With new values dpll still generate 300MHz clock, but EMAC work. Probably with new values dpll generate more stable clock. dpll on rk3188 provide clocks to DDR and EMAC. With current dpll settings EMAC doesn't work on radxa rock. EMAC sends packets to network, but it doesn't receive anything. ifconfig shows a lot of framing errors.

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.

2017-04-04rockchip: clk: rk3188: Allow configuration of the armclkHeiko Stübner
The armclk starts in slow mode (24MHz) on the rk3188, which makes the whole startup take a lot of time. We therefore want to at least move to the safe 600MHz value we can use with default pmic settings. This is also the freqency the proprietary sdram-init leaves the cpu at. For boards that have pmic control later in u-boot, we also add the option to set the maximum frequency of 1.6GHz, if they so desire.
