From: Gabriel Fernandez <gabriel.fernandez at st.com>

v3:
 - remove arm & DT patches from this patch-set
 - solve issue of dependency with DT
 - remove clk_hw from struct stm32_rgate (use hw of clk_gate)
 - suppress CLK_IS_BASIC flags of clk_register_rgate()
 - cosmetic changes

v2:
 - rename compatible property "st,stm32f46xx-rcc" into "st,stm32f469-rcc"
 - cosmetic: remove bad copy/paste

This patch-set introduce RTC and QSPI clocks for STM32F4 socs
RTC clock has 3 parents clock oscillators (lsi/lse/hse_rtc)

example to use rtc clock:

		rtc: rtc at 40002800 {
			compatible = "st,stm32-rtc";
			reg = <0x40002800 0x400>;
			...
			clocks = <&rcc 1 CLK_RTC>;

			assigned-clocks =  <&rcc 1 CLK_RTC>;
			assigned-clock-parents = <&rcc 1 CLK_LSE>;
			...
		};

Gabriel Fernandez (3):
  clk: stm32f4: Add LSI & LSE clocks
  clk: stm32f4: Add RTC clock
  clk: stm32f469: Add QSPI clock
