2015-10-01clk: mediatek: Add USB clock support in MT8173 APMIXEDSYSJames Liao
Add REF2USB_TX clock support into MT8173 APMIXEDSYS. This clock is needed by USB 3.0. Signed-off-by: James Liao <jamesjj.liao@mediatek.com> Reviewed-by: Daniel Kurtz <djkurtz@chromium.org>
2015-10-01clk: mediatek: Add subsystem clocks of MT8173James Liao
Most multimedia subsystem clocks will be accessed by multiple drivers, so it's a better way to manage these clocks in CCF. This patch adds clock support for MM, IMG, VDEC, VENC and VENC_LT subsystems. Signed-off-by: James Liao <jamesjj.liao@mediatek.com> Reviewed-by: Daniel Kurtz <djkurtz@chromium.org>
2015-10-01clk: mediatek: Fix rate and dependency of MT8173 clocksJames Liao
Remove the dependency from clk_null, and give all root clocks a typical rate, include clkph_mck_o, usb_syspll_125m and hdmitx_dig_cts. dpi_ck was removed due to no clock reference to it. Replace parent clock of infra_cpum with cpum_ck, which is an external clock and can be defined in the device tree.

2015-10-01clk: mediatek: Add __initdata and __init for data and functionsJames Liao
Add __init for clock registration functions, and add __initdata for mtk_gate_regs initial structures. Signed-off-by: James Liao <jamesjj.liao@mediatek.com> Reviewed-by: Daniel Kurtz <djkurtz@chromium.org>
2015-10-01clk: mediatek: Remove unused code from MT8173.James Liao
Remove unused header files from MT8173, and remove unused keywords from function declaration. Signed-off-by: James Liao <jamesjj.liao@mediatek.com> Reviewed-by: Daniel Kurtz <djkurtz@chromium.org>
2015-10-01clk: mediatek: Removed unused dpi_ck clock from MT8173James Liao
The dpi_ck clock can be removed because it not actually used in topckgen and subsystems. Signed-off-by: James Liao <jamesjj.liao@mediatek.com> Reviewed-by: Daniel Kurtz <djkurtz@chromium.org>

2015-07-28clk: mediatek: Add MT8173 MMPLL change rate supportJames Liao
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.

2015-07-20clk: mediatek: Properly include clk.hStephen Boyd
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.

2015-07-06clk: mediatek: mt8173: Fix enabling of critical clocksSascha Hauer
On the MT8173 the clocks are provided by different units. To enable the critical clocks we must be sure that all parent clocks are already registered, otherwise the parents of the critical clocks end up being unused and get disabled later. To find a place where all parents are registered we try each time after we've registered some clocks if all known providers are present now and only then we enable the critical clocks Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: James Liao <jamesjj.liao@mediatek.com> [sboyd@codeaurora.org: Marked function and data __init] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2015-06-04clk: mediatek: Fix apmixedsys clock registrationJames Liao
The size of clk_data should be the same as CLK_APMIXED_NR_CLK instead of ARRAY_SIZE(plls). CLK_APMIXED_* is numbered from 1, so CLK_APMIXED_NR_CLK will be greater than ARRAY_SIZE(plls).
