Subject: [RESEND PATCH v8 0/3] clk: stm32h7: Add stm32h743 clock driver

From: Gabriel Fernandez <gabriel.fernandez@...com>

v8:
  - Documentation remarks from Valdimir:
	- rename 'rcc' node name into 'reset-clock-controller'
	- delete source paths into the device tree bindings documentation
	- other cosmetic changes
v7:
  - Documentation: put 'st,syscfg' phandle in optional section
  - rename nxp gate op with lpc32xx_ prefix
  - Suppress useless code to disable/enable backup domain write protection
    (backup domaine write is disable at the init and never enabled)

v6:
  - rename clk_gate_is_enabled() in nxp lpc32xx driver.
  - add EXPORT_SYMBOL_GPL(clk_gate_is_enabled)

v5:
  - return bool instead int for enable_power_domain_write_protection()
  - add comment to explain use of CLK_OF_DECLARE_DRIVER()
  - add comment to explain why we can't use read_poll_timeout()
  - expose clk_gate_ops::is_enabled
  - use of __clk_mux_determine_rate & clk_gate_is_enabled to avoid wrapper
	function.

v4:
  - rename lock into stm32rcc_lock
  - don't use clk_readl() 
  - remove useless parentheses with GENMASK
  - fix parents of timer_x clocks
  - suppress pll configuration from DT
  - fix kbuild warning

v3:
  - fix compatible string "stm32h7-pll" into "st,stm32h7-pll"
  - fix bad parent name for mco2 clock
  - set CLK_SET_RATE_PARENT for ltdc clock
  - set CLK_IGNORE_UNUSED for pll1
  - disable power domain write protection on disable ops if needed


v2:
  - rename compatible string "stm32,pll" into "stm32h7-pll"
  - suppress "st,pllrge" property
  - suppress "st, frac-status" property
  - change management of "st,frac"  property
	0 : enable 0 pll integer mode 
	other values : enable pll in fractional mode (value is
	the fractional factor)

Gabriel Fernandez (3):
  clk: nxp: clk-lpc32xx: rename clk_gate_is_enabled()
  clk: gate: expose clk_gate_ops::is_enabled
  clk: stm32h7: Add stm32h743 clock driver
