Hi, This is the V5 of my patchset that adds support to the Timer/Counter Unit (TCU) present on Ingenic JZ47xx SoCs. Way too much has changed since V4, we went from 8 patches in V4 up to 21 patches in V5. I did not know if I had to submit it as V5 or start a new series. In doubt, I sent a V5. Very succint description of the changes: - The interrupt, clocks, clocksource drivers have been merged into one; ingenic-timer now inits the TCU clocks, handles the interrupts, provides a system timer and optionally also a clocksource and sched_clock. The TCU channel #0 will be used as system timer, unless another channel is specified from devicetree. - The simple-mfd and syscon are gone. The ingenic-timer driver will probe the drivers registered as children in the devicetree. - The watchdog driver was updated to use the WDT clock and regmap provided by ingenic-timer. This breaks the devicetree ABI, but as explained in the corresponding commit message, right now all Ingenic boards compile the devicetree into the kernel anyway - so it's better to update it now before it's too late. - The PWM driver was updated to use the TCU timer clocks as well as the regmap provided by ingenic-timer. Unused devicetree compatible strings were removed (the driver was never probed from devicetree), and support for the JZ4725B has been added. - A new ingenic-ost driver was added, which provides a clocksource and a sched_clock that are more accurate than the ones provided by ingenic-timer (32 or 64-bit vs. 16-bit). It is not available on every SoC. - Mostly tested on the JZ4725B and JZ4770. It would be great if somebody could test on the JZ4780 and JZ4740.
