2016-12-09clk: add devm_get_clk_from_child() APIKuninori Morimoto1-0/+21
Some driver is using this type of DT bindings for clock (more detail, see ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.txt). sound_soc { ... cpu { clocks = <&xxx>; ... }; codec { clocks = <&xxx>; ... }; }; Current driver in this case uses of_clk_get() for each node, but there is no devm_of_clk_get() today. OTOH, the problem of having devm_of_clk_get() is that it encourages the use of of_clk_get() when clk_get() is more desirable. Thus, this patch adds new devm_get_clk_from_chile() which explicitly reads as get a clock from a child node of this device. By this function, we can also use this type of DT bindings sound_soc { clocks = <&xxx>, <&xxx>; clock-names = "cpu", "codec"; clock-ranges; ... cpu { ... }; codec { ... }; }; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> [sboyd@codeurora.org: Rename subject to clk + add API] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2016-12-09clk: bcm: Make COMMON_CLK_IPROC into a libraryStephen Boyd1-11/+5
The broadcom clk driver Kconfig file selects and depends on the COMMON_CLK_IPROC config for different SoC specific drivers. Let's simplify this by always selecting the COMMON_CLK_IPROC config, turning it into a set of library code. We still want to retain the SoC specific options, so we leave those in place. Since we're here we also drop COMMON_CLK dependency because that's implicitly handled by including this file in drivers/clk/Kconfig in the right place and also make CLK_BCM_KONA default to y on the architecture it exists for instead of plain default y.

2016-12-09clk: bcm: Support rate change propagation on bcm2835 clocksBoris Brezillon1-4/+63
Some peripheral clocks, like the VEC (Video EnCoder) clock need to be set to a precise rate (in our case 108MHz). With the current implementation, where peripheral clocks are not allowed to forward rate change requests to their parents, it is impossible to match this requirement unless the bootloader has configured things correctly, or a specific rate has been assigned through the DT (with the assigned-clk-rates property). Add a new field to struct bcm2835_clock_data to specify which parent clocks accept rate change propagation, and support set rate propagation in bcm2835_clock_determine_rate().

2016-12-09clk: ti: omap36xx: Work around sprz319 advisory 2.1Richard Watts4-11/+104
The OMAP36xx DPLL5, driving EHCI USB, can be subject to a long-term frequency drift. The frequency drift magnitude depends on the VCO update rate, which is inversely proportional to the PLL divider. The kernel DPLL configuration code results in a high value for the divider, leading to a long term drift high enough to cause USB transmission errors. In the worst case the USB PHY's ULPI interface can stop responding, breaking USB operation completely. This manifests itself on the Beagleboard xM by the LAN9514 reporting 'Cannot enable port 2. Maybe the cable is bad?' in the kernel log. Errata sprz319 advisory 2.1 documents PLL values that minimize the drift. Use them automatically when DPLL5 is used for USB operation, which we detect based on the requested clock rate. The clock framework will still compute the PLL parameters and resulting rate as usual, but the PLL M and N values will then be overridden. This can result in the effective clock rate being slightly different than the rate cached by the clock framework, but won't cause any adverse effect to USB operation.

2016-11-16clk: berlin: Pass correct type to hw provider registrationStephen Boyd2-2/+2
Dan Carpenter reports that we're passing a pointer to a pointer here when we should just be passing a pointer. Pass the right pointer so that the of_clk_hw_onecell_get() sees the appropriate data pointer on its end.

2016-11-15clk: Hi6220: enable stub clock driver for ARCH_HISILeo Yan1-0/+1
In current kernel config 'CONFIG_STUB_CLK_HI6220' is disabled by default, as result stub clock driver has not been registered and CPUFreq driver cannot work. This patch is to enable stub clock driver in config for ARCH_HISI.

git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next Pull Rockchip clk driver updates from Heiko Stuebner: PLL initialization for PLLs having both an integral and fractional mode (rk3036, rk3399) does now take into account the mode that the PLL is actually running at. As always also some additional and optimized PLL rates for rk3066 and rk3399, some additional clock ids for rk3066 and some additional clocks on rk3399 are now sucessfully handled inside their respective driver. * tag 'v4.10-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip: clk: rockchip: Ignore frac divisor for PLL equivalence when it's unused clk: rockchip: remove more CLK_IGNORE_UNUSED for rk3399 clocktree clk: rockchip: add 400MHz to rk3066 clock rates table clk: rockchip: optimize 800MHz and 1GHz pll rates on RK3399 clk: rockchip: Use clock ids for cpu and peri clocks on rk3066 clk: rockchip: Add binding ids for cpu and peri clocks on rk3066 clk: rockchip: add 533.25MHz to rk3399 clock rates table
