The following changes were done: * Split programming the PLL into updating m,n,p and updating cpcon * Move locking from _update_pll_cpcon() to clk_pll_set_rate() * Introduce _get_pll_mnp() helper * Move check for identical m,n,p values to clk_pll_set_rate() * struct tegra_clk_pll_freq_table will always contain the values as defined by the hardware. * Simplify the arguments to clk_pll_wait_for_lock() Signed-off-by: Peter De Schrijver Tested-by: Stephen Warren Reviewed-by: Stephen Warren --- drivers/clk/tegra/clk-pll.c | 178 +++++++++++++++++------------ drivers/clk/tegra/clk-tegra20.c | 144 ++++++++++++------------ drivers/clk/tegra/clk-tegra30.c | 234 +++++++++++++++++++------------------- 3 files changed, 294 insertions(+), 262 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html diff --git a/drivers/clk/tegra/clk-pll.c b/drivers/clk/tegra/clk-pll.c index 165f247..912c977 100644 --- a/drivers/clk/tegra/clk-pll.c +++ b/drivers/clk/tegra/clk-pll.c @@ -1,5 +1,5 @@ /* - * Copyright (c) 2012, NVIDIA CORPORATION.
