From: Gabriel Fernandez <gabriel.fernandez@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@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
