[v3,0/5] Add A5 SoC PLLs and Peripheral clock

Message

Xianwei Zhao via B4 Relay Jan. 3, 2025, 5:36 a.m. UTC

The patchset adds support for the peripheral and PLL clock controller
found on the Amlogic A5 SoC family, such as A113X2.

Some clocks are provided by security zones. These clock accessed
througth SCMI driver in linux, inlcuding OSC, SYS_CLK, AXI_CLK,
CPU_CLK, DSU_CLK, GP1_PLL, FIXED_PLL_DCO, FIXED_PLL, SYS_PLL_DIV16,
ACLKM, CPU_CLK_DIV16, FCLK_50M_PREDIV, FCLK_50M_DIV, FCLK_50M, 
FCLK_DIV2_DIV, FCLK_DIV2, FCLK_DIV2P5_DIV, FCLK_DIV2P5, FCLK_DIV3_DIV,
FCLK_DIV3, FCLK_DIV4_DIV, FCLK_DIV4, FCLK_DIV5_DIV, FCLK_DIV5,
FCLK_DIV7_DIV, FCLK_DIV7, CLKID_SYS_MMC_PCLK, CLKID_SYS_CPU_CTRL,
CLKID_SYS_IRQ_CTRL, CLKID_SYS_GIC, CLKID_SYS_BIG_NIC, CLKID_AXI_SYS_NIC,
and CLKID_AXI_CPU_DMC.

Changes in v3:
- Rename xtal_24m to xtal, and modify some description of Kconfig.
- Drop some comment of PLL source code.
- Move definition of A5_CLK_GATE_FW frome common code into A5 peripheral source code.
- Use hw instead of name to describe parent_data.
- Making SCMI binding the first to submit. 
- Link to v2: https://lore.kernel.org/r/[e-mail]

Changes in v2:
- Move some sys clock and axi clock from peripheral to scmi impletement.
- Remove  ARM_SCMI_PROTOCOL in Kconfig and correct name A5 but not A4.
- Add two optional clock inputs for the peripheral(ddr pll and clk-measure)
- Make some changes and adjustments according to suggestions.
- Link to v1: https://lore.kernel.org/r/[e-mail]
