Joachim Eastwood 378523d150 clk: add lpc18xx creg clk driver
The CREG block on lpc18xx contains configuration register
for two low power clocks. Support enabling of these two
clocks with a clk driver that access CREG trough the
syscon regmap interface.

These clocks are needed to support peripherals like the
internal RTC on lpc18xx.

Vladimir Zapolskiy f7c82a60ba clk: lpc32xx: add common clock framework driver
Add support for all configurable clocks found on NXP LPC32xx SoC.

The list contains several heterogenous groups of clocks:
* system clocks including multiple dividers and muxes,
* x397 PLL, HCLK PLL and USB PLL,
* peripheral clocks inherited from rtc, hclk and pclk,
* USB controller clocks: AHB slave, I2C, OTG, OHCI and device.

Joachim Eastwood 472cd304a3 clk: add lpc18xx ccu clk driver
Add driver for NXP LPC18xx/43xx Clock Control Unit (CCU). The CCU
provides fine grained gating of most clocks present in the SoC.

Joachim Eastwood b04e0b8fd5 clk: add lpc18xx cgu clk driver
Add driver for NXP LPC18xx/43xx Clock Generation Unit (CGU). The CGU
contains several clock generators and output stages that route the
clocks either directly to peripherals or to a Clock Control Unit
(CCU).
