2017-08-04clk: meson: meson8b: register the built-in reset controllerMartin Blumenstingl
The clock controller also includes some reset lines. This patch implements a reset controller to assert and de-assert these resets. The reset controller itself is registered early (through CLK_OF_DECLARE_DRIVER) because it is needed very early in the boot process (to start the secondary CPU cores). According to the public S805 datasheet there are two more reset bits in the HHI_SYS_CPU_CLK_CNTL0 register, which are not implemented by this patch (as these seem to be unused in Amlogic's vendor Linux kernel sources and their u-boot tree): - bit 15: GEN_DIV_SOFT_RESET - bit 14: SOFT_RESET All information was taken from the public S805 Datasheet and Amlogic's vendor GPL kernel sources. This patch is based on an earlier version submitted by Carlo Caione.

2016-09-01meson: clk: Add support for clock gatesAlexander Müller
This patch adds support for the meson8b clock gates. Most of them are disabled by Amlogic U-Boot, but need to be enabled for ethernet, USB and many other components.

2016-09-01clk: meson: Copy meson8b CLKID defines to private header fileAlexander Müller
Only expose future CLKID constants if necessary. This patch removes CLK_NR_CLKS from the DT bindings but leaves all previously defined CLKIDs there to keep backward compatibility.
