clk: gxbb: add AmLogic GXBB clk controller driver The gxbb clock controller is the primary clock generation unit for the AmLogic GXBB SoC. It is clocked by a fixed 24MHz xtal, contains several PLLs and the usual post-dividers, muxes, dividers and leaf gates that are fed into various IP blocks in the SoC.

clk: meson-gxbb: Add GXL/GXM GP0 Variant The clock tree in the Amlogic GXBB and GXL/GXM SoCs is shared, but the GXL/GXM SoCs embeds a different GP0 PLL, and needs different parameters with a vendor provided reduced rate table. This patch adds the GXL GP0 variant, and adds a GXL DT compatible in order to use the GXL GP0 PLL instead of the GXBB specific one.

clk: meson: gxbb: remove the "cpu_clk" from the GXBB and GXL driver It seems that the "cpu_clk" was carried over from the meson8b clock controller driver. On Meson GX (GXBB/GXL/GXM) the registers which are used by the cpu_clk have a different purpose (in other words: they don't control the CPU clock anymore). HHI_SYS_CPU_CLK_CNTL1 bits 31:24 are reserved according to the public S905 datasheet, while bit 23 is the "A53_trace_clk_DIS" gate (which according to the datasheet should only be used in case a silicon bug is discovered) and bits 22:20 are a divider (A53_trace_clk). The meson clk-cpu code however expects that bits 28:20 are reserved for a divider (according to the public S805 datasheet this "SCALE_DIV: This value represents an N+1 divider of the input clock."). The CPU clock on Meson GX SoCs is provided by the SCPI DVFS clock driver instead. Two examples from a Meson GXL S905X SoC: - vcpu (SCPI DVFS clock 0) rate: 1000000000 / cpu_clk rate: 708000000 - vcpu (SCPI DVFS clock 0) rate: 1512000000 / cpu_clk rate: 708000000 Unfortunately the CLKID_CPUCLK was already exported (but is currently not used) to DT. Due to the removal of this clock definition there is now a hole in the clk_hw_onecell_data (which is not a problem because this case is already handled in gxbb_clkc_probe).

clk: gxbb: add the SAR ADC clocks and expose them The HHI_SAR_CLK_CNTL contains three SAR ADC specific clocks: - a mux clock to choose between different ADC reference clocks (this is 2-bit wide, but the datasheet only lists the parents for the first bit) - a divider for the input/reference clock - a gate which enables the ADC clock Additionally this exposes the ADC core clock (CLKID_SAR_ADC) and CLKID_SANA (which seems to enable the analog inputs, but unfortunately there is no documentation for this - we just mimic what the vendor driver does).

The EE 32k_clk must be pushed earlier since mainline support for CEC in the Synopsys HDMI-TX controller is nearby.
