clk: meson: add triple phase clock driver Add a driver to control the output of the sample clock generator found in the axg audio clock controller. The goal of this driver is to coherently control the phase provided to the different element using the sample clock generator. This simplify the usage of the sample clock generator a lot, without comprising the ability of the SoC.

clk: meson: add regmap clocks Meson clock controllers need to move the classical iomem registers to regmap. This is triggered because the HHI controllers found on the GXBB and GXL host more than just clocks. To properly handle this, we would like to migrate HHI to syscon. Also GXBB AO clock controller already use regmap, AXG AO and Audio clock controllers will as well. The purpose of this change is to provide a common structure to these meson controllers (and possibly others) for regmap based clocks. This change provides the basic gate, mux and divider, based on the helpers provided by the related generic clocks Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>

clk: meson: meson8b: register the built-in reset controller 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.

clk: meson: meson8b: add compatibles for Meson8 and Meson8m2 The clock controller on Meson8, Meson8b and Meson8m2 is very similar based on the code from the Amlogic GPL kernel sources. Add separate compatibles for each SoC to make sure that we can easily implement all the small differences for each SoC later on. In general the Meson8 and Meson8m2 seem to be almost identical as they even share the same mach-meson8 directory in Amlogic's GPL kernel sources. The main clocks on Meson8, Meson8b and Meson8m2 are very similar, because they are all using the same PLL values, 90% of the clock gates are the same (the actual diffstat of the mach-meson8/clock.c and mach-meson8b/clock.c files is around 30 to 40 lines, when excluding all commented out code). The difference between the Meson8 and Meson8b clock gates seem to be: - Meson8 has AIU_PCLK, HDMI_RX, VCLK2_ENCT, VCLK2_ENCL, UART3, CSI_DIG_CLKIN gates which don't seem to be available on Meson8b - the gate on Meson8 for bit 7 seems to be named "_1200XXX" instead of "PERIPHS_TOP" (on Meson8b) - Meson8b has a SANA gate which doesn't seem to exist on Meson8 (or on Meson8 the same bit is used by the UART3 gate in Amlogic's GPL kernel sources) None of these gates is added for now, since it's unclear whether these definitions are actually correct (the VCLK2_ENCT gate for example is defined, but only used in some commented block). The main difference between all three SoCs seem to be the video (VPU) clocks. Apart from different supported clock rates (according to vpu.c in mach-meson8 and mach-meson8b from Amlogic's GPL kernel sources) the most notable difference is that Meson8m2 has a GP_PLL clock and a mux (probably the same as on the Meson GX SoCs) to support glitch-free (clock rate) switching. None of these VPU clocks are not supported by our mainline meson8b clock driver yet though.
