I'll send a patchset which has another fix for another case like this one (plus the fix for the typo). The patchset is actually switching all the imx6 and imx7 clocks to clk_hw based API, but will include all the necessary fixes for that to work. > Signed-off-by: Abel Vesa <abel.vesa@nxp.com> > --- > drivers/clk/imx/clk-imx6q.c | 8 -------- > 1 file changed, 8 deletions(-) > > diff --git a/drivers/clk/imx/clk-imx6q.c b/drivers/clk/imx/clk-imx6q.c > index 708e7c5..c7b671e 100644 > --- a/drivers/clk/imx/clk-imx6q.c > +++ b/drivers/clk/imx/clk-imx6q.c > @@ -291,12 +291,6 @@ static void mmdc_ch1_disable(void __iomem *ccm_base) > clk_set_parent(clk[IMX6QDL_CLK_PERIPH2_CLK2_SEL], > clk[IMX6QDL_CLK_PLL3_USB_OTG]); > > - /* > - * Handshake with mmdc_ch1 module must be masked when changing > - * periph2_clk_sel. > - */ > - clk_set_parent(clk[IMX6QDL_CLK_PERIPH2], clk[IMX6QDL_CLK_PERIPH2_CLK2]); > - > /* Disable pll3_sw_clk by selecting the bypass clock source */ > reg = readl_relaxed(ccm_base + CCM_CCSR); > reg |= CCSR_PLL3_SW_CLK_SEL; > @@ -311,8 +305,6 @@ static void mmdc_ch1_reenable(void __iomem *ccm_base) > reg = readl_relaxed(ccm_base + CCM_CCSR); > reg &= ~CCSR_PLL3_SW_CLK_SEL; > writel_relaxed(reg, ccm_base + CCM_CCSR); > - > - clk_set_parent(clk[IMX6QDL_CLK_PERIPH2], clk[IMX6QDL_CLK_PERIPH2_PRE]); > } > > /* > -- > 2.7.4 >
