Dong Aisheng	f83d31635c	clk: imx: fix pll clock parents ... pllx_bypass_src mux shouldn't be the parent of pllx clock since it's only valid when when pllx BYPASS bit is set. Thus it is actually one parent of pllx_bypass only. Instead, pllx parent should be fixed to osc according to reference manual. Other plls have the same issue. e.g. before fix, the pll tree is: osc 6 6 24000000 0 0 pll1_bypass_src 0 0 24000000 0 0 pll1 0 0 792000000 0 0 pll1_bypass 0 0 792000000 0 0 pll1_sys 0 0 792000000 0 0 After the fix, it's: osc 6 6 24000000 0 0 pll1 0 0 792000000 0 0 pll1_bypass 0 0 792000000 0 0 pll1_sys 0 0 792000000 0 0 Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>	2016-06-12 21:21:41 +08:00
Shengjiu Wang	84a87250ee	clk: imx6: Add SPDIF_GCLK clock in clock tree ... Correct SPDIF clock setting issue in clock tree, the SPDIF_GCLK is also one clock of SPDIF, which is missed before. We found an issue that imx can't enter low power mode with spdif if IMX6x_CLK_SPDIF is used as the core clock of spdif. Because spdif driver will register IMX6x_CLK_SPDIF clock to regmap, regmap will do clk_prepare in init function, then IMX6x_CLK_SPDIF clock is prepared in probe, so its parent clock (PLL clock) is prepared, the prepare operation of PLL clock is to enable the clock. But I.MX needs all PLL clock is disabled, then it can enter low power mode. So we can't use IMX6x_CLK_SPDIF as the core clock of spdif, the correct spdif core clock is SPDIF_GCLK, which share same gate bit with IMX6x_CLK_SPDIF clock. SPDIF_GCLK's parent clock is ipg clock.

Shawn Guo	11f6812009	ARM: imx: move clock drivers into drivers/clk ... After the cleanup on clock drivers, they are now ready to be moved into drivers/clk. Let's move them into drivers/clk/imx folder. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Stephen Boyd <sboyd@codeaurora.org>	2015-06-03 14:44:33 +08:00
