From 4b5fb7dc9096d949a22651370bb6bf11f21edb30 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Sun, 12 Jul 2015 22:49:53 +0200 Subject: [PATCH] clk: pxa: fix core frequency reporting unit Legacy drivers which are not yet ported, such as cpufreq-pxa[23]xx, rely on pxaXXx_get_clk_frequency_khz() to find the CPU core frequency. This reporting was broken because the expected unit is kHz and not Hz. Fix the reporting for pxa25x, pxa27x and pxa3xx. Fixes: fe7710fae477 ("clk: add pxa25x clock drivers") Fixes: d40670dc6169 ("clk: add pxa27x clock drivers") Fixes: 9bbb8a338fb2 ("clk: pxa: add pxa3xx clock driver") Signed-off-by: Robert Jarzmik Signed-off-by: Stephen Boyd --- drivers/clk/pxa/clk-pxa25x.c | 2 +- drivers/clk/pxa/clk-pxa27x.c | 2 +- drivers/clk/pxa/clk-pxa3xx.c | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/clk/pxa/clk-pxa25x.c b/drivers/clk/pxa/clk-pxa25x.c index 6cd88d9..542e45e 100644 --- a/drivers/clk/pxa/clk-pxa25x.c +++ b/drivers/clk/pxa/clk-pxa25x.c @@ -79,7 +79,7 @@ unsigned int pxa25x_get_clk_frequency_khz(int info) clks[3] / 1000000, (clks[3] % 1000000) / 10000); } - return (unsigned int)clks[0]; + return (unsigned int)clks[0] / KHz; } static unsigned long clk_pxa25x_memory_get_rate(struct clk_hw *hw, diff --git a/drivers/clk/pxa/clk-pxa27x.c b/drivers/clk/pxa/clk-pxa27x.c index 9a31b77..5b82d30 100644 --- a/drivers/clk/pxa/clk-pxa27x.c +++ b/drivers/clk/pxa/clk-pxa27x.c @@ -80,7 +80,7 @@ unsigned int pxa27x_get_clk_frequency_khz(int info) pr_info("System bus clock: %ld.%02ldMHz\n", clks[4] / 1000000, (clks[4] % 1000000) / 10000); } - return (unsigned int)clks[0]; + return (unsigned int)clks[0] / KHz; } bool pxa27x_is_ppll_disabled(void) diff --git a/drivers/clk/pxa/clk-pxa3xx.c b/drivers/clk/pxa/clk-pxa3xx.c index 4b93a1e..c677b9a 100644 --- a/drivers/clk/pxa/clk-pxa3xx.c +++ b/drivers/clk/pxa/clk-pxa3xx.c @@ -78,7 +78,7 @@ unsigned int pxa3xx_get_clk_frequency_khz(int info) pr_info("System bus clock: %ld.%02ldMHz\n", clks[4] / 1000000, (clks[4] % 1000000) / 10000); } - return (unsigned int)clks[0]; + return (unsigned int)clks[0] / KHz; } static unsigned long clk_pxa3xx_ac97_get_rate(struct clk_hw *hw, -- 2.7.4
