2023-08-22clk: nuvoton: Convert to devm_platform_ioremap_resource()Yangtao Li
Use devm_platform_ioremap_resource() to simplify code. Signed-off-by: Yangtao Li <frank.li@vivo.com> Link: https://lore.kernel.org/r/20230705065313.67043-12-frank.li@vivo.com Acked-by: Jacky Huang <ychuang3@nuvoton.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2023-06-22clk: nuvoton: Use clk_parent_data instead of string for parent clockJacky Huang
For the declaration of parent clocks, use struct clk_parent_data instead of a string. Due to the change in the passed arguments, replace the usage of devm_clk_hw_register_mux() with clk_hw_register_mux_parent_data() for all cases.

2023-06-22clk: nuvoton: Update all constant hex values to lowercaseJacky Huang
The constant hex values used to define register offsets were written in uppercase. This patch update all these constant hex values to be lowercase. Signed-off-by: Jacky Huang <ychuang3@nuvoton.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2023-06-22clk: nuvoton: Add clk-ma35d1.h for driver extern functionsJacky Huang
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. Signed-off-by: Jacky Huang <ychuang3@nuvoton.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2023-06-05clk: nuvoton: Add clock driver for ma35d1 clock controllerJacky Huang
The clock controller generates clocks for the whole chip, including system clocks and all peripheral clocks. This driver support ma35d1 clock gating, divider, and individual PLL configuration. There are 6 PLLs in ma35d1 SoC: - CA-PLL for the two Cortex-A35 CPU clock - SYS-PLL for system bus, which comes from the companion MCU and cannot be programmed by clock controller. - DDR-PLL for DDR - EPLL for GMAC and GFX, Display, and VDEC IPs. - VPLL for video output pixel clock - APLL for SDHC, I2S audio, and other IPs. CA-PLL has only one operation mode. DDR-PLL, EPLL, VPLL, and APLL are advanced PLLs which have 3 operation modes: integer mode, fraction mode, and spread specturm mode.
