jbrunet 2d3b74d383 clk: gxbb: fix CLKID_ETH defined twice
CLKID_ETH is define in the dt-bindings but has not be commented out in the
clock driver. Just do it now.

Martin Blumenstingl 33d0fcdfe0 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).

Martin Blumenstingl 5dbe7890e6 clk: gxbb: expose USB clocks
USB0_DDR_BRIDGE and USB1_DDR_BRIDGE1 are needed for the related
dwc2 usb controller. USB, USB0 and USB1 are needed for the PHYs.
Expose these clocks to DT and comment out in clk driver.

Martin Blumenstingl ed6f4b5180 clk: gxbb: expose MPLL2 clock for use by DT
This exposes the MPLL2 clock as this is one of the input clocks of the
ethernet controller's internal mux.

Kevin Hilman 33608dcd01 clk: gxbb: add MMC gate clocks, and expose for DT
Add the SD/eMMC gate clocks and expose them for use by DT.

While at it, also explose FCLK_DIV2 since this is one of the input
clocks to the mux internal to each of the SD/eMMC blocks.

Michael Turquette ca1d2e269f Revert "clk: gxbb: expose CLKID_MMC_PCLK"
This reverts commit e16fb2e635.

Updated documentation from the chip vendor reveals that this clock is
not required for correct operation of the MMC controller. As such, do
not expose it to DT.

Michael Turquette 738f66d321 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.
