正式开始之前 驱动中的clk_hw_onecell_data结构存储clk的数量以及clk_hw结构,每一个clk都有自己的clk_hw结构。也就是说驱动中会使用hws[clk_index]的形式存储每一个clk信息。 structclk_hw_onecell_data{ unsignedintnum; structclk_hw*hws[]; }; structclk_hw{ structclk_core*core; structclk*clk; cons...
static void clk_gate_set_bit(struct clk_gate *gate) { u32 reg; reg = __raw_readl(gate->reg); reg |= BIT(gate->bit_idx); writel(reg, gate->reg); } Note that to_clk_gate is defined as: #define to_clk_gate(_hw) container_of(_hw, struct clk_gate, hw) This pattern of ...

To illustrate consider the simple gateable clk implementation in drivers/clk/clk-gate.c: struct clk_gate { struct clk_hw hw; void __iomem *reg; u8 bit_idx; ... }; struct clk_gate contains struct clk_hw hw as well as hardware-specific knowledge about which register and bit contro...
Uninfected cell samples were used to draw the infected cell gate. Infected cells were considered LIVE/DEADNeg, CD14Int/PosCD4−p24+ (macrophages) or CD3PosCD4−p24+ (CD4+ T cells). Frequencies of this population were compared between DMSO, Lamivudine/Lopinavir + Ritonavir, and 1H3-...
On dm814x we have 13 ADPLLs with 3 to 4 outputs on each. The ADPLLs have several dividers and muxes controlled by a shared control register for each PLL. Note that for the clocks to work as device drivers for booting on dm814x, this patch depends on "ARM: OMAP2+: Change core_ini...
