pll4311 (also known in the vendor kernel as frd_4311_rpll) is a PLL used in the Exynos2200 SoC. It's an integer/fractional PLL with mid frequency FVCO (650 to 3500Mhz). The PLL is functionally similar enough to pll531x, so the same code can handle both. Locktime for pll4311 is 500 - the same as the pll531x lock factor. MDIV, PDIV, SDIV and FDIV masks and bit shifts are also the same as pll531x. When defining a PLL, the "con" parameter should be set to CON3 register, like this: PLL(pll_4311, CLK_FOUT_SHARED0_PLL, "fout_shared0_pll", "oscclk", PLL_LOCKTIME_PLL_SHARED0, PLL_CON3_PLL_SHARED0, NULL), Signed-off-by: Ivaylo Ivanov <ivo.ivanov.ivanov1@gmail.com> --- drivers/clk/samsung/clk-pll.c | 1 + drivers/clk/samsung/clk-pll.h | 1 + 2 files changed, 2 insertions(+)
