SubjectRe: [PATCH v6 6/9] clk: stm32: Fix ltdc's clock turn off by clk_disable_unused() after kernel startup
Quoting (2020-05-27 00:27:30)
> From: dillon min <>
> stm32's clk driver register two ltdc gate clk to clk core by
> clk_hw_register_gate() and clk_hw_register_composite()
> first: 'stm32f429_gates[]', clk name is 'ltdc', which no user to use.
> second: 'stm32f429_aux_clk[]', clk name is 'lcd-tft', used by ltdc driver
> both of them point to the same offset of stm32's RCC register. after
> kernel enter console, clk core turn off ltdc's clk as 'stm32f429_gates[]'
> is no one to use. but, actually 'stm32f429_aux_clk[]' is in use.
