STRUCT CCS_PLL_BRANCH_LIMITS_BK(9)

💅 struct ccs_pll_branch_limits_bk — NAME ✨

ok so bestie, welcome to the Kernel API Manual 🫶, and buckle up because this one is literally the vibe-check page for struct ccs_pll_branch_limits_bk — aka the CCS PLL back-end limits 👑. that's it, that's the whole name, she's a limits struct and she's serving.

---

🌸 SYNOPSIS 🌸

here's the whole shape of her, no cap, type it exactly like this:

struct ccs_pll_branch_limits_bk {
    u16 min_sys_clk_div;
    u16 max_sys_clk_div;
    u32 min_sys_clk_freq_hz;
    u32 max_sys_clk_freq_hz;
    u16 min_pix_clk_div;
    u16 max_pix_clk_div;
    u32 min_pix_clk_freq_hz;
    u32 max_pix_clk_freq_hz;
 };

look at that little }; sitting there with its own indentation — she's quirky, we love her 💜

🎀 Members 🎀

okay so every single field, one by one, because we do not skip anyone in this group chat:

• min_sys_clk_div — the minimum system clock divider, like the floor of the sys clk div situation 🦋
• max_sys_clk_div — the maximum system clock divider, the ceiling, the limit, the "no further than this" energy ✨
• min_sys_clk_freq_hz — the minimum system clock frequency, in hz ofc 💖
• max_sys_clk_freq_hz — the maximum system clock frequency, also in hz, also iconic 🔥
• min_pix_clk_div — the minimum pixel clock divider, pix clk's own little floor 🌸
• max_pix_clk_div — the maximum pixel clock divider, pix clk's own little ceiling 🎀
• min_pix_clk_freq_hz — the minimum pixel clock frequency, hz again bestie, consistency ate 💅
• max_pix_clk_freq_hz — the maximum pixel clock frequency, hz, maximum, periodt 🌈

so yeah — four sys clk boundaries and four pix clk boundaries, min/max div and min/max freq for each. divs are u16, freqs are u32. that's the whole struct, she's compact and she knows it 💀

🦋 SEE ALSO 🦋

go read these next, iykyk, they're all in the kernel file ./drivers/media/i2c/ccs-pll.h:

• struct ccs_pll_branch_fr(9)
• struct ccs_pll_branch_bk(9)
• struct ccs_pll(9)
• struct ccs_pll_branch_limits_fr(9)
• struct ccs_pll_limits(9)
• ccs_pll_calculate(9)

like genuinely go read ccs_pll_calculate(9) if you wanna see where these limits actually get used 🔍

---

bestie reminder: these are limits — min and max. don't go passing a divider outside its range and then act surprised, i'm begging 🙈

and that's the page!! mwah 💋 this little beauty lives in ./drivers/media/i2c, dated October 2026, and her header/footer both just say struct ccs_...ch_limits_bk(9) because the terminal cut her name off and honestly? relatable. slay, truncated queen 👑✨
