We're removing struct clk from the clk provider API, so switch this code to using the clk_hw based provider APIs. This also removes a clk_get() in this driver that can just as easily use of_clk_get_parent_name() instead.

This code is never called with a basic clock type, so the check here is not doing anything useful and is blocking the removal of __clk_get_flags(). Remove the check so we can delete the __clk_get_flags() API. Acked-by:

clk providers shouldn't need to use the consumer APIs (clk.h). Add provider APIs to replace the __clk_*() APIs that take a struct clk_hw as their first argument instead of a struct clk. Signed-off-by:

Neither spdif_src nor spdif_pll exists, judging by the vendor kernel in both cases spdif_pre was meant. This brings the naming in line and hierachy in line with that of sclk_i2s0. Also allow sclk_spdif and spdif_frac to change their parents rate as that the upstream dividers are purely there to feed sclk_spdif 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:

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:
