2014-09-27clk: sunxi: Move mbus to mod0 fileMaxime Ripard2-57/+12
Move the MBUS clock to the module clocks file. It's pretty trivial, but still requires to enable the clocks to make sure it won't get disabled. Signed-off-by: Maxime Ripard <[email protected]> Acked-by: Hans de Goede <[email protected]>
2014-09-27clk: sunxi: Move mod0 clock to a file of its ownMaxime Ripard3-1/+83
Since we know have the ability to declare factors clock outside of clk-sunxi, create a new mod0 driver to deal with the mod0 clocks. Signed-off-by: Maxime Ripard <[email protected]> Acked-by: Hans de Goede <[email protected]>
2014-09-27ARM: sunxi: dt: Switch to the new mbus compatibleMaxime Ripard3-3/+3
Now that we have a compatible of its own for the mbus clock, switch to it. Signed-off-by: Maxime Ripard <[email protected]> Acked-by: Hans de Goede <[email protected]>
2014-09-27clk: sunxi: Introduce mbus compatibleMaxime Ripard2-0/+2
Even though the mbus clock is a regular module clock, given its nature, it needs to be enabled all the time. Introduce a new compatible, to differentiate it from the other module clocks. Signed-off-by: Maxime Ripard <[email protected]> Acked-by: Hans de Goede <[email protected]>
2014-09-27clk: sunxi: factors: Invert the probing logicMaxime Ripard3-99/+113
Until now, the factors clock probing was done directly by sunxi_init_clocks, with the factors registration being called directly with the clocks data passed as an argument. This approch has shown its limits when we added more clocks, since we couldn't really split code with such a logic in smaller files, and led to a huge file having all the clocks. Introduce an intermediate probing function, so that factor clocks will be able to directly be called by CLK_OF_DECLARE, which will in turn ease the split into several files.

2014-09-27clk: Add a function to retrieve phaseMaxime Ripard2-0/+15
The current phase API doesn't look into the actual hardware to get the phase value, but will rather get it from a variable only set by the set_phase function. This will cause issue when the client driver will never call the set_phase function, where we can end up having a reported phase that will not match what the hardware has been programmed to by the bootloader or what phase is programmed out of reset. Add a new get_phase function for the drivers to implement so that we can get this value.

2014-09-27clk: Include of.h in clock-provider.hMaxime Ripard1-0/+1

2014-09-27clk: introduce clk_set_phase function & callbackMike Turquette4-4/+116
A common operation for a clock signal generator is to shift the phase of that signal. This patch introduces a new function to the clk.h API to dynamically adjust the phase of a clock signal. Additionally this patch introduces support for the new function in the common clock framework via the .set_phase call back in struct clk_ops.

2014-09-13clk: sunxi: add correct divider table for sun4i-apb0 clockChen-Yu Tsai1-0/+9
The sun4i-apb0 clock, as found on all platforms using it, is a power-of-two-based divider clock, with a special divider of 2 for value 0. This was causing the clock framework to incorrectly calculate the clock rate for apb1 and related modules on sun6i and sun8i. On sun[4/5/7]i, u-boot SPL configures the divider with value 1 for /2 divider, so no suprises there. This patch adds a proper divider table for it, so the correct clock rate can be calculated.

Some Toshiba models (most notably Qosmios) come with an incomplete backlight method where the AML code doesn't check for write or read commands and always returns HCI_SUCCESS and the actual brightness (and in some cases the max brightness), thus allowing the backlight interface to be registered without write support.

When bl_power support got added to asus-wmi, the error handling for it was written to ignore -ENODEV, to avoid not registering a backlight interface for models which have no bl_power control, but do have brightness control.
