Nothing uses it, and I can't find any evidence that anything ever has. Its role is now filled by the core clock in the firmware driver. Signed-off-by:

While children of orphan clocks are not carried in the orphan-list itself, they're nevertheless orphans in their own right as they also don't have an input-rate available. To ease tracking if a clock is an orphan or has an orphan in its parent path introduce an orphan field into struct clk and update it and the fields in child-clocks when a clock gets added or removed from the orphan-list.

The gates were handled with a common piece of framework that was registering all gates array, that was not using the CLK_OF_DECLARE logic, and was not using clock-indices but some private masks that were pretty much equivalent. Move this code in a new driver that handles all the gates array and solves both these issues. Signed-off-by:

The TSADC gate clock was used in Exynos4x12 DTSI for exynos-adc driver. However TSADC is present only on Exynos4210 so on Trats2 board (with Exynos4412 SoC) the exynos-adc driver could not be probed: ERROR: could not get clock /adc@126C0000:adc(0) exynos-adc 126c0000.adc: failed getting clock, err = -2 exynos-adc: probe of 126c0000.adc failed with error -2 Instead on Exynos4x12 SoCs the main clock used by Analog to Digital Converter is located in different register and it is named in datasheet as PCLK_ADC. Regardless of the name the purpose of this PCLK_ADC clock is the same as purpose of TSADC from Exynos4210. The patch adds gate clock for Exynos4x12 using the proper register so backward compatibility is preserved. This fixes the probe of exynos-adc driver on Exynos4x12 boards and allows accessing sensors connected to it on Trats2 board (ntc,ncp15wb473 AP and battery thermistors). Signed-off-by:

Rob Herring authored
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code. Signed-off-by:

This commit allows certain Broadcom STB clock dividers to be used with clk-divider.c. It allows for a clock whose field value is the equal to the divisor, execpt when the field value is zero, in which case the divisor is 2^width. For example, consider a divisor clock with a two bit field: value divisor 0 4 1 1 2 2 3 3 Signed-off-by:

In the TRM we see that BWADJ is "a 12-bit bus that selects the values 1-4096 for the bandwidth divider (NB)": NB = BWADJ[11:0] + 1 The recommended setting of NB: NB = NF / 2. So: NB = NF / 2 BWADJ[11:0] + 1 = NF / 2 BWADJ[11:0] = NF / 2 - 1 Right now, we have: { \ .rate = _rate##U, \ .nr = _nr, \ .nf = _nf, \ .no = _no, \ .bwadj = (_nf >> 1), \ } That means we set bwadj to NF / 2, not NF / 2 - 1 All of this is a bit confusing because we specify "NR" (the 1-based value), "NF" (the 1-based value), "NO" (the 1-based value), but "BWADJ" (the 0-based value) instead of "NB" (the 1-based value). Let's change to working with "NB" and fix the off by one error. This may affect PLL jitter in a small way (hopefully for the better). Signed-off-by:

clk providers are using the consumer APIs to set min/max rates on the clock they're providing. To encourage clk providers to move away from the consumer APIs, add a provider API to set the min/max rate of a clock. The assumption is that this is done before the clock can be requested via clk_get() and that the clock rate is already within the boundaries of the min/max that's configured. Tested-by:
