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
