2018-07-09clk: meson: stop rate propagation for audio clocksJerome Brunet1-9/+7
It is actually a lot easier to setup the PLL with carefully chosen rates than relying on CCF clock propagation for this audio use case. This way, we can make sure we will always be able to provide the common audio clock rates, while having the PLL in the optimal operating range. For this, we stop the rate propagation at the mux picking the PLL and let it round to the closest matching PLL. Doing so, we can use the generic divider for the i2s clock. clk-audio-divider is no longer required. It was a (poor) attempt to use CCF rate propagation while making sure the PLL rate would be high enough to work with audio use cases.

2018-07-09clk: meson: axg: add the audio clock controller driverJerome Brunet4-0/+982
The axg audio clock controller is the clock generation unit for the amlogic audio subsystem of A113 based SoCs. It may be clocked by 8 different plls provided by the primary clock controller and also by 10 slave bit clocks and 10 slave sample clocks which may be provided by external components, such as audio codecs, through the SoC pads. It contains several muxes, dividers and gates which are fed into the the different devices of the audio subsystem.

2018-07-09clk: meson: add axg audio sclk divider driverJerome Brunet3-1/+252
Add a driver to control the clock divider found in the sample clock generator of the axg audio clock controller. The sclk divider accumulates specific features which make the generic divider unsuitable to control it: - zero based divider (div = val + 1), but zero value gates the clock, so minimum divider value is 2. - lrclk variant may adjust the duty cycle depending the divider value and the 'hi' value.

Add a driver to control the output of the sample clock generator found in the axg audio clock controller. The goal of this driver is to coherently control the phase provided to the different element using the sample clock generator.

2018-07-06clk: Add driver for MAX9485Daniel Mack3-0/+394
This patch adds a driver for MAX9485, a programmable audio clock generator. The device requires a 27.000 MHz clock input. It can provide a gated buffered output of its input clock and two gated outputs of a PLL that can generate one out of 16 discrete frequencies. There is only one PLL however, so the two gated outputs will always have the same frequency but they can be switched individually. The driver for this device exposes 4 clocks in total: - MAX9485_MCLKOUT: A gated, buffered output of the input clock - MAX9485_CLKOUT: A PLL that can be configured to 16 different discrete frequencies - MAX9485_CLKOUT[1,2]: Two gated outputs for MAX9485_CLKOUT Some PLL output frequencies can be achieved with different register settings. The driver will select the one with lowest jitter in such cases.

2018-07-06clk: aspeed: Treat a gate in reset as disabledBenjamin Herrenschmidt1-0/+13
On some systems, we come out of the bootloader with some gates set with the clock "enabled" but the reset also asserted. Since 8a53fc511c5e "clk: aspeed: Prevent reset if clock is enabled" we check that enabled bit in aspeed_clk_enabled(), and do nothing if already set. This breaks when the above scenario occurs, as the clock is enabled, but the reset still needs to be lifted. This patch fixes it by also checking the reset bit (if any) and treating a gate in "reset" as being disabled.

i.MX6UL has GPIO clock gates in CCM CCGR, add them into clock tree for clock management. Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2018-06-29clk: imx6sx: remove clks_init_on arrayAnson Huang1-26/+14
Clock framework will enable those clocks registered with CLK_IS_CRITICAL flag, so no need to have clks_init_on array during clock initialization now. ARM clock is busy divider type which has the CLK_IS_CRITICAL flag set by default when registered. IPG clock has no clock gate and its parent AHB clock is busy divider type, so no need to add CLK_IS_CRITICAL flag for IPG clock.
