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>
2017-08-11sunxi: add PRCM secure switch register definitionIcenowy Zheng
Some new Allwinner SoCs' PRCM has a secure switch register, which controls the access to some clock and power registers in PRCM block. Add the definition of this register and its bits in the PRCM header file.

2016-06-20sunxi: Group cpu core related controls togetherChen-Yu Tsai
Instead of listing individual registers for controls to each processor core, list them as an array of registers. This makes accessing controls by core index easier. Also rename "cpucfg_sun6i.h" (which was unused anyway) to the more generic "cpucfg.h", and add packed attribute to struct sunxi_cpucfg.

2016-06-20sunxi: Add packed attribute to struct sunxi_prcm_regChen-Yu Tsai
struct sunxi_prcm_reg is a representation of the PRCM registers. Add the packed attribute to prevent the compiler from doing funny things. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2015-01-14sunxi: Add support for the rsb (Reduced Serial Bus)Hans de Goede
sun8i (A23) introduces a new bus for communicating with the pmic, the rsb, the rsb is also used to communicate with the pmic on the A80, and is documented in the A80 user manual. This commit adds support for this based on the rsb driver from the allwinner u-boot sources. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2014-11-13sun6i: Add clock functions needed for SPL / DRAM initHans de Goede
Add clock_init_safe and clockset_pll5 functions, as these are needed for SPL support resp. DRAM init (which is needed for SPL too). Also add some extra clock register constant defines. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

The prcm apb0 controls multiple modules. Allow specifying which modules to enable clocks and de-assert resets so the function can be reused. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2014-10-24ARM: sun6i: Add support for the power reset control module found on the A31Oliver Schinagl
The A31 has a new module called PRCM, or Power, Reset Control Module. This module controls clocks and resets for RTC block modules, and also PLL biasing in the main clock module. This patch adds the register definitions, and also enables the clocks and resets for the RTC block PIO (pin controller) and P2WI (push-pull 2 wire interface) which is used to talk to the PMIC.
