* stm32mp1: clk: configure pll1 with OPPPatrick Delaunay2020-07-071-0/+4
| | | | | | | | The PLL1 node (st,pll1) is optional in device tree, the max supported frequency define in OPP node is used when the node is absent. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
* ARM: dts: stm32m1: add reg for pll nodesPatrick Delaunay2020-02-131-4/+28
| | | | | | | | | | | | | | | | Fix the following DT dtc warnings for stm32mp1 boards: Warning (unit_address_vs_reg): /soc/rcc@50000000/st,pll@0: node has a unit name, but no reg property Warning (unit_address_vs_reg): /soc/rcc@50000000/st,pll@1: node has a unit name, but no reg property Warning (unit_address_vs_reg): /soc/rcc@50000000/st,pll@2: node has a unit name, but no reg property Warning (unit_address_vs_reg): /soc/rcc@50000000/st,pll@3: node has a unit name, but no reg property Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
* dt-bindings: clock: stm32mp1: support disabled fixed clockPatrick Delaunay2019-08-271-1/+3
| | | | | | Add precision for disabled fixed clock in stm32mp1 binding. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
* stm32mp1: update RCC binding after kernel realignmentPatrick Delaunay2019-05-231-140/+287
| | | | | | | RCC is no more a mfd and add a complete example and alignment with latest TF-A binding Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
* clk: stm32mp1: correctly handle Clock Spreading GeneratorPatrick Delaunay2019-02-091-5/+5
| | | | | | | | To activate the csg option, the driver need to set the bit2 of PLLNCR register = SSCG_CTRL: Spread Spectrum Clock Generator of PLLn enable. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
* stm32mp1: clk: support digital bypassPatrick Delaunay2018-07-201-1/+3
| | | | | | | | | HSE and LSE bypass shall support both analog and digital signals. This patch add a way to select digital bypas case in the device tree and set the associated bit DIGBYP in RCC_BDCR and RCC_OCEN register during clock tree initialization.
