* clk: mediatek: make dpi0_sel propagate rate changesPhilipp Zabel2016-05-06
| | | | | | | | | This mux is supposed to select a fitting divider after the PLL is already set to the correct rate. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Acked-by: James Liao <jamesjj.liao@mediatek.com> Acked-by: Stephen Boyd <sboyd@codeaurora.org>

| * clk: mediatek: Properly include clk.hStephen Boyd2015-07-20
| | | | | | | | | | | | | | | | | | | | | | We don't need to include clk.h in header files, just forward declare struct clk here. This leads us to a few places where the include of clk.h was missing in C files. Add them.

* | clk: mediatek: Add MT8173 MMPLL change rate supportJames Liao2015-07-28
|/ | | | | | | | | | | | MT8173 MMPLL frequency settings are different from common PLLs. It needs different post divider settings for some ranges of frequency. This patch add support for MT8173 MMPLL frequency setting by adding div-rate table to lookup suitable post divider setting under a specified frequency.

* clk: mediatek: Add reset controller supportSascha Hauer2015-05-06
| | | | | | | | | | | | | | | The pericfg and infracfg units also provide reset lines to several other SoC internal units. This adds a function which can be called from the pericfg and infracfg initialization functions which will register the reset controller using reset_controller_register. The reset controller will provide support for resetting the units connected to the pericfg and infracfg controller. The units resetted by this controller can use the standard reset device tree binding to gain access to the reset lines.
