2017-06-14clk: keystone: Add sci-clk driver supportTero Kristo5-9/+743
In K2G, the clock handling is done through firmware executing on a separate core. Linux kernel needs to communicate to the firmware through TI system control interface to access any power management related resources, including clocks. The keystone sci-clk driver does this, by communicating to the firmware through the TI SCI driver. The driver adds support for registering clocks through DT, and basic required clock operations like prepare/get_rate, etc. Signed-off-by: Tero Kristo <t-kristo@ti.com> [sboyd@codeaurora.org: Make ti_sci_init_clocks() static] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-06-12clk: meson: meson8b: add compatibles for Meson8 and Meson8m2Martin Blumenstingl2-4/+7
The clock controller on Meson8, Meson8b and Meson8m2 is very similar based on the code from the Amlogic GPL kernel sources. Add separate compatibles for each SoC to make sure that we can easily implement all the small differences for each SoC later on. In general the Meson8 and Meson8m2 seem to be almost identical as they even share the same mach-meson8 directory in Amlogic's GPL kernel sources. The main clocks on Meson8, Meson8b and Meson8m2 are very similar, because they are all using the same PLL values, 90% of the clock gates are the same (the actual diffstat of the mach-meson8/clock.c and mach-meson8b/clock.c files is around 30 to 40 lines, when excluding all commented out code). The difference between the Meson8 and Meson8b clock gates seem to be: - Meson8 has AIU_PCLK, HDMI_RX, VCLK2_ENCT, VCLK2_ENCL, UART3, CSI_DIG_CLKIN gates which don't seem to be available on Meson8b - the gate on Meson8 for bit 7 seems to be named "_1200XXX" instead of "PERIPHS_TOP" (on Meson8b) - Meson8b has a SANA gate which doesn't seem to exist on Meson8 (or on Meson8 the same bit is used by the UART3 gate in Amlogic's GPL kernel sources) None of these gates is added for now, since it's unclear whether these definitions are actually correct (the VCLK2_ENCT gate for example is defined, but only used in some commented block). The main difference between all three SoCs seem to be the video (VPU) clocks. Apart from different supported clock rates (according to vpu.c in mach-meson8 and mach-meson8b from Amlogic's GPL kernel sources) the most notable difference is that Meson8m2 has a GP_PLL clock and a mux (probably the same as on the Meson GX SoCs) to support glitch-free (clock rate) switching. None of these VPU clocks are not supported by our mainline meson8b clock driver yet though.

2017-06-07clk: sunxi-ng: Move all clock types to a libraryStephen Boyd2-132/+22
We've run into kconfig missing dependency errors in the sunxi-ng code a couple times now. Each time the fix is to find the missing select statement and add it to the Kconfig entry for a particular SoC driver. Given that all this code is builtin (non-modular) we don't need to do this complicated dependency tracking in Kconfig. Instead we can move all the "library"ish code to be compiled as lib-y instead of obj-y, let the linker throw away unused code in the resulting vmlinux, and drop all the Kconfig stuff we use to track clock types.

2017-06-07clk: sunxi-ng: Add driver for A83T CCUChen-Yu Tsai4-0/+998
The A83T clock control unit is a hybrid of some new style clock designs from the A80, and old style layout from the other Allwinner SoCs. Like the A80, the SoC does not have a low speed 32.768 kHz oscillator. Unlike the A80, there is no clock input either. The only low speed clock available is the internal oscillator which runs at around 16 MHz, divided by 512, yielding a low speed clock around 31.250 kHz. Also, the MMC2 module clock supports switching to a "new timing" mode. This mode divides the clock output by half, and disables the CCU based clock delays. The MMC controller must be configure to the same mode, and then use its internal clock delays. This driver does not support runtime switching of the timing modes. Instead, the new timing mode is enforced at probe time. Consumers can check which mode is active by trying to get the current phase delay of the MMC2 phase clocks, which will return -ENOTSUPP if the new timing mode is active.

2017-06-07clk: sunxi-ng: Support multiple variable pre-dividersChen-Yu Tsai9-47/+54
On the A83T, the AHB1 clock has a shared pre-divider on the two PLL-PERIPH clock parents. To support such instances of shared pre-dividers, this patch extends the mux clock type to support multiple variable pre-dividers. As the pre-dividers are only used to calculate the rate, but do not participate in the factorization process, this is fairly straightforward.

2017-06-07clk: sunxi-ng: mux: Re-adjust parent rateMaxime Ripard1-5/+28
Currently, the parent rate given back to the clock framework in our request is the original parent rate we calculated before trying to round the rate of our clock. This works fine unless our clock also changes its parent rate, in which case we will simply ignore that change and still use the previous parent rate. Create a new function to re-adjust the parent rate to take the pre-dividers into account, and give that back to the clock framework.

2017-06-07clk: sunxi-ng: mux: Change pre-divider application function prototypeMaxime Ripard5-33/+28
The current function name is a bit confusing, and doesn't really allow to create an explicit function to reverse the operation. We also for now change the parent rate through a pointer, while we don't return anything.

The pre-divider retrieval code was merged into the function to apply the current pre-divider onto the parent clock rate so that we can use that adjusted value to do our factors computation.

2017-06-07clk: sunxi-ng: mux: Don't just rely on the parent for CLK_SET_RATE_PARENTMaxime Ripard1-13/+1
The current code only rely on the parent to change its rate in the case where CLK_SET_RATE_PARENT is set. However, some clock rates might be obtained only through a modification of the parent and the clock divider. Just rely on the round rate of the clocks to give us the best computation that might be achieved for a given rate. round_rate functions now need to honor CLK_SET_RATE_PARENT, but either the functions already do that if they modify the parent, or don't modify the praents at all.

2017-06-07clk: divider: Make divider_round_rate take the parent clockMaxime Ripard1-9/+10
So far, divider_round_rate only considers the parent clock returned by clk_hw_get_parent. This works fine on clocks that have a single parents, this doesn't work on muxes, since we will only consider the first parent, while other parents may totally be able to provide a better combination. Clocks in that case cannot use divider_round_rate, so would have to come up with a very similar logic to work around it. Instead of having to do something like this, and duplicate that logic everywhere, create a divider_round_rate parent to allow caller to give an additional parameter for the parent clock to consider.

2017-06-02clk: rockchip: mark some special clk as critical on rk3368Elaine Zhang1-1/+4
The jtag clk no driver to handle them. But this clk need enable,so make it as critical. The ddrphy/ddrupctl clks no driver to handle them, Chip design requirements for these clock to always on, The pmu_hclk_otg0 is Chip design defect, must be always on, Signed-off-by: Elaine Zhang <zhangqing@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de>

The atclk/dbg/jtag/hsic-xin12m/pclk_core clks no driver to handle them. But this clks need enable,so make it as ignore_unused for now. The ddrupctl0/ddrupctl1/publ0/publ1 clks no driver to handle them, Chip design requirements for these clock to always on, The pmu_hclk_otg0 is Chip design defect, must be always on, Signed-off-by: Elaine Zhang <zhangqing@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de>

The jtag/bus/peri/initmem/rom/stimer/phy clks no driver to handle them. But this clks need enable,so make it as critical. The ddrupctl/ddrmon/ddrphy clks no driver to handle them, Chip design requirements for these clock to always on, The hclk_otg_pmu is Chip design defect, must be always on, The new document will update the description of this clock. All these non-noc/non-arbi clocks,IC suggest always on, Because it's have some order limitation, between the NOC clock switch and bus IDLE(or pd on/off). The software is not very good to solve this constraint. Always on these clocks, has no effect on the system power consumption. The new document will update the description of these clock.
