clk: at91: Add clock driver

2016-08-15T20:12:00+00:00

The patch is referred to at91 clock driver of Linux, to make
the clock node descriptions in DT aligned with the Linux's.

clock: add Tegra186 clock driver

2016-08-15T17:26:13+00:00

In Tegra186, on-SoC clocks are manipulated using IPC requests to the BPMP
(Boot and Power Management Processor). This change implements a driver
that does that. A tegra/ sub-directory is created to follow the existing
pattern. It is unconditionally selected by CONFIG_TEGRA186 since virtually
any Tegra186 build of U-Boot will need the feature.

rockchip: remove log2 reimplementation from clock drivers

2016-08-06T00:07:07+00:00

The already available ilog2 function does exactly the same in the common
case than the log2 function the current clock-driver reimplement.
So, simply move to that one.

clock: rk3399: add support for dwmmc 400K

2016-08-06T00:02:51+00:00

MMC core will use 400KHz for card initialize first and then switch to
higher frequency like 50MHz, we need to support both 400KHz and about
50MHz for dwmmc controller.

move: rockchip: move clock drivers into a subdirectory

2016-08-05T23:56:08+00:00

With the number of Rockchip clock drivers increasing, don't clutter up
the core drivers/clk directory with them and instead move them out of
the way into a separate subdirectory.

rockchip: Use rockchip_get_clk() to obtain the SoC clock

2016-07-26T02:46:45+00:00

The current code picks the first available clock. In U-Boot proper this is
the oscillator device, not the SoC clock device. As a result the HDMI display
does not work.

Fix this by calling rockchip_get_clk() instead.

rockchip: rk3288: fix FREF_MIN_HZ constant

2016-07-26T02:44:20+00:00

According to the TRM the minimum FREF frequency is 269kHz not MHz.
Adapt the constant accordingly.

cosmetic: rockchip: rk3288: rename rkclk_configure_cpu

2016-07-26T02:44:20+00:00

The function is very specific to the rk3288 in its arguments
referencing the rk3288 cru and grf and every other rockchip soc
has differing cru and grf registers. So make that function naming
explicit.
