2015-12-02ARM: imx: clk-vf610: fix SAI clock treeStefan Agner1-4/+4
The Synchronous Audio Interface (SAI) instances are clocked by independent clocks: The bus clock and the audio clock (as shown in Figure 51-1 in the Vybrid Reference Manual). The clock gates in CCGR0/CCGR1 for SAI0 through SAI3 are bus clock gates, as access tests to the registers with/without gating those clocks have shown. The audio clock is gated by the SAIx_EN gates in CCM_CSCDR1, followed by a clock divider (SAIx_DIV). Currently, the parent of the bus clock gates has been assigned to SAIx_DIV, which is not involved in the bus clock path for the SAI instances (see chapter 9.10.12, SAI clocking in the Vybrid Reference Manual). Fix this by define the parent clock of VF610_CLK_SAIx to be the bus clock. If the driver needs the audio clock (when used in master mode), a fixed device tree is required which assign the audio clock properly to VF610_CLK_SAIx_DIV.

2015-10-12clk: imx6: Add SPDIF_GCLK clock in clock treeShengjiu Wang3-2/+7
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.

2015-06-03ARM: imx: clk-vf610: enable debug access port by defaultStefan Agner1-0/+2
Enabled DAP (debug access port) by default. This enables the hw- breakpoint framework to make use of the breakpoints and watchpoints supported by hardware. [ 0.215805] hw-breakpoint: found 2 (+1 reserved) breakpoint and 1 watchpoint registers. [ 0.224624] hw-breakpoint: maximum watchpoint size is 4 bytes. Without this clock, the hw-breakpoint driver claims an undefined instruction during initialization: [ 0.227380] hw-breakpoint: Debug register access (0xee003e17) caused undefined instruction on CPU 0 [ 0.227519] hw-breakpoint: CPU 0 failed to disable vector catch Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2015-06-03clk: imx: clk-cpu: Include "clk.h" header fileFabio Estevam1-0/+1
Include the "clk.h" header file to fix the following sparse warning: drivers/clk/imx/clk-cpu.c:77:12: warning: symbol 'imx_clk_cpu' was not declared. Should it be static? Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2015-06-03ARM: imx: using unsigned variable for do_divAnson Huang1-2/+2
The definition of do_div uses unsigned long long variable as its first parameter, better to pass a u64 variable as first parameter when calling do_div function.

2015-06-03ARM: imx: drop epit timer initialization from imx35 clock driverShawn Guo1-4/+0
EPIT provides another timer implementation besides the default GPT timer. The imx35 clock driver will use EPIT timer when option CONFIG_MXC_USE_EPIT is enabled. However, initializing timers from clock driver is a workaround solution and causes problem when we move clock drivers into driver/clk. Let's simply drop the EPIT initialization from there. If people really want this EPIT option, EPIT timer driver needs to be reworked to do the initialization in a standard way - use CLOCKSOURCE_OF_DECLARE() with device tree support.

2015-06-03ARM: imx: move clock drivers into drivers/clkShawn Guo24-0/+5814
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>
