Instead of 2^20 divide factor, the -clock's ndiv integer shift was used. Fixed the bug by replacing ndiv -integer shift with 2^20 factor. - -Signed-off-by: Simran Rai <ssimran@broadcom.com> -Signed-off-by: Ray Jui <rjui@broadcom.com> -Reviewed-by: Scott Branden <sbranden@broadcom.com> -Fixes: 5fe225c105fd ("clk: iproc: add initial common clock support") -Cc: <stable@vger.kernel.org> # v4.1+ -Signed-off-by: Michael Turquette <mturquette@baylibre.com> ---- - drivers/clk/bcm/clk-iproc-pll.c | 13 +++++-------- - 1 file changed, 5 insertions(+), 8 deletions(-) - ---- a/drivers/clk/bcm/clk-iproc-pll.c -+++ b/drivers/clk/bcm/clk-iproc-pll.c -@@ -345,8 +345,8 @@ static unsigned long iproc_pll_recalc_ra - struct iproc_pll *pll = clk->pll; - const struct iproc_pll_ctrl *ctrl = pll->ctrl; - u32 val; -- u64 ndiv; -- unsigned int ndiv_int, ndiv_frac, pdiv; -+ u64 ndiv, ndiv_int, ndiv_frac; -+ unsigned int pdiv; - - if (parent_rate == 0) - return 0; -@@ -366,22 +366,19 @@ static unsigned long iproc_pll_recalc_ra - val = readl(pll->pll_base + ctrl->ndiv_int.offset); - ndiv_int = (val >> ctrl->ndiv_int.shift) & - bit_mask(ctrl->ndiv_int.width); -- ndiv = (u64)ndiv_int << ctrl->ndiv_int.shift; -+ ndiv = ndiv_int << 20; - - if (ctrl->flags & IPROC_CLK_PLL_HAS_NDIV_FRAC) { - val = readl(pll->pll_base + ctrl->ndiv_frac.offset); - ndiv_frac = (val >> ctrl->ndiv_frac.shift) & - bit_mask(ctrl->ndiv_frac.width); -- -- if (ndiv_frac != 0) -- ndiv = ((u64)ndiv_int << ctrl->ndiv_int.shift) | -- ndiv_frac; -+ ndiv += ndiv_frac; - } - - val = readl(pll->pll_base + ctrl->pdiv.offset); - pdiv = (val >> ctrl->pdiv.shift) & bit_mask(ctrl->pdiv.width); - -- clk->rate = (ndiv * parent_rate) >> ctrl->ndiv_int.shift; -+ clk->rate = (ndiv * parent_rate) >> 20; - - if (pdiv == 0) - clk->rate *= 2; |
