This patch is the Flexgen implementation reusing as much as possible of Common Clock Framework functions. The idea is to have an instance of "struct flexgen" per output clock. It represents the clock cross bar (by a mux element), and the pre and final dividers (using dividers and gates elements). Signed-off-by:

Merge tag 'qcom-clocks-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/galak/linux-qcom into clk-next-msm qcom clock changes for 3.17 These patches add support for a handful of Qualcomm's SoC clock controllers: APQ8084 gcc and mmcc, IPQ8064 gcc, and APQ8064. There's also a small collection of bug fixes that aren't critical -rc worthy regressions because the consumer drivers aren't present or using the buggy clocks and one optimization for HDMI.

This patch adds helper functions to configure clock parents and rates as specified through 'assigned-clock-parents', 'assigned-clock-rates' DT properties for a clock provider or clock consumer device. The helpers are now being called by the bus code for the platform, I2C and SPI busses, before the driver probing and also in the clock core after registration of a clock provider. Signed-off-by:

The APQ8064 multimedia clock controller is fairly similar to the 8960 multimedia clock controller, except that gfx2d0/1 has been removed and the gfx3d frequency is slightly faster when using the newly introduced PLL15. We also add vcap clocks and a couple new TV clocks. Signed-off-by:Stephen Boyd <sboyd@codeaurora.org>

Sometimes we need to program PLLs with a fixed rate configuration during driver probe. Doing this after we register the PLLs with the clock framework causes the common clock framework to assume the rate of the PLLs are 0. This causes all sorts of problems for rate recalculations because the common clock framework caches the rate once at registration time unless a flag is set to always recalculate the rates. Split the qcom_cc_probe() function into two pieces, map and everything else, so that drivers which need to configure some PLL rates or otherwise twiddle bits in the clock controller can do so before registering clocks. This allows us to properly detect the rates of PLLs that are programmed at boot. Fixes: 49fc825f "clk: qcom: Consolidate common probe code" Signed-off-by:

Clocks that don't have a pre-divider don't list any pre-divider in their frequency tables, but their tables are initialized using aggregate initializers. Use tagged initializers so we properly assign the m and n values for each frequency. Furthermore, the mmcc_pxo_pll8_pll2_pll3 array improperly mapped the second element to pll2 instead of pll8, causing the clock driver to recalculate the wrong rate for any clocks using this array along with a rate that uses pll2. Plus the .num_parents field is 3 instead of 4 so you can't even switch the parent to pll3. Finally I noticed that the jpegd clock improperly indicates that the pre-divider width is only 2, when it's actually 4 bits wide.

In the case of HDMI clocks, we want to bypass the RCG's ability to divide the output clock and pass through the parent HDMI PLL rate. Add a simple set of clk_ops to configure the RCG to do this. This removes the need to keep adding more frequency entries to the tv_src clock whenever we want to support a new rate. Tested-by:

sun6i-apb0-gates uses the "clock-indices" DT property to indicate valid gate bits or holes in between. However, the rest of sunxi clock drivers use bitmaps for this purpose. This patch modifies sun6i-apb0-gates to use bitmaps as well, to be consistent with the sunxi platform. Also add the missing call to clk_register_clkdev, so system clock lookups will work.

This adds a clock driver that handles the specific muxes, dividers and gates of rk3188 and rk3066 SoCs. The structure of the clock list resembles the arrangement of their counterparts in the clock architecture diagrams found in the SoC documentation. Clocks exported to the clock provider are currently limited to well known or measured ones. So additional clock exports may be necessary in the future. Signed-off-by:

All Rockchip SoCs at least down to the ARM9-based RK28xx include the reset- controller for SoC peripherals in their clock controller. While the older SoCs (ARM9 and Cortex-A8) use a regular scheme to change register values, the Cortex-A9 SoCs use a hiword-mask making locking unecessary. To be compatible with both schemes the reset controller takes a flag to decide which scheme to use, similar to the other HIWORD_MASK flags used in the clock framework. Signed-off-by:

All known Rockchip SoCs down to the RK28xx (ARM9) use a similar pattern to handle their plls: |--\ xin32k ----------------|mux\ xin24m -----| pll |----|pll|--- pll output \---------------|src/ |--/ The pll output is sourced from 1 of 3 sources, the actual pll being one of them. To change the pll frequency it is imperative to remux it to another source beforehand. This is done by adding a clock-listener to the pll that handles the remuxing before and after the rate change. The output mux is implemented as a separate clock to make use of already existing common-clock features for disabling the pll if one of the other two sources is used. Signed-off-by: -

This adds infrastructure for registering clock branches. On Rockchip SoCs most clock branches are a combination of mux,divider and gate components, thus a composite clock is used when appropriate. Clock branches are supposed to be declared in an array using the COMPOSITE* or MUX, etc makros defined in the header and then registered using rockchip_clk_register_branches. Signed-off-by:
