From: Lubomir Rintel <lkundrak@v3.sk> [ Upstream commit 8bea5ac0fbc5b2103f8779ddff216122e3c2e1ad ] Determined empirically, no documentation is available. The OLPC XO-1.75 laptop used parent 1, that one being VCTCXO/4 (65MHz), but thought it's a VCTCXO/2 (130MHz). The mmp2 timer driver, not knowing what is going on, ended up just dividing the rate as of commit f36797ee4380 ("ARM: mmp/mmp2: dt: enable the clock")' Link: https://lore.kernel.org/r/20191218190454.420358-3-lkundrak@v3.sk Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Acked-by: Stephen Boyd <sboyd@kernel.org> Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> --- drivers/clk/mmp/clk-of-mmp2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/clk/mmp/clk-of-mmp2.c b/drivers/clk/mmp/clk-of-mmp2.c index d083b86..10689d8 100644 --- a/drivers/clk/mmp/clk-of-mmp2.c +++ b/drivers/clk/mmp/clk-of-mmp2.c @@ -134,7 +134,7 @@ static void mmp2_pll_init(struct mmp2_clk_unit *pxa_unit) static const char *ssp_parent_names[] = {"vctcxo_4", "vctcxo_2", "vctcxo", "pll1_16"}; static DEFINE_SPINLOCK(timer_lock); -static const char *timer_parent_names[] = {"clk32", "vctcxo_2", "vctcxo_4", "vctcxo"}; +static const char *timer_parent_names[] = {"clk32", "vctcxo_4", "vctcxo_2", "vctcxo"}; static DEFINE_SPINLOCK(reset_lock); -- 1.8.3
