[PATCH v2 1/2] clk: nuvoton: Add clk-ma35d1.h for driver extern functions

Tue Jun 20 20:16:04 PDT 2023


From: Jacky Huang <ychuang3 at nuvoton.com>

Moved the declaration of extern functions ma35d1_reg_clk_pll() and
ma35d1_reg_adc_clkdiv() from the .c files to the newly created header
file clk-ma35d1.h.
