Meson GX SoCs however use some magic bits to prevent simultaneous (= conflicting, because only consumer should use the FIFO buffer with the ADC results) usage by the Linux kernel and the bootloader (the BL30 bootloader uses the SAR ADC to read the CPU temperature). This patch changes guards all BL30 functionality so it is skipped on SoCs which don't have it. Since the hardware itself doesn't know whether BL30 is available the internal meson_sar_adc_data is extended so this information can be provided per of_device_id.data inside the driver. Additionally the clocks "adc_clk" and "adc_sel" are not provided by the clock-controller itself. "adc_sel" is not available at all. "adc_clk" is provided by the SAR ADC IP block itself on Meson8b (and earlier). This is already supported by the meson_saradc driver. Finally this introduces new of_device_ids for the Meson8 and Meson8b SoCs so the driver can be wired up in the corresponding DT.
