[PATCH v4 4/6] drivers/i2c: Add I2C master locking to FSI algorithm

[RFC PATCH v3] irqchip: Add support for tango interrupt router

This controller maps 128 input lines to 24 output lines. The output lines are routed to GIC SPI 0 to 23. This driver muxes LEVEL_HIGH IRQs onto output line 0, and gives every EDGE_RISING IRQ a dedicated output line. --- I think the driver is mostly finished. It works without errors for my basic

[PATCH] ARM64: dts: fixup libretech cc definition

The libretech CC derives less from the p212 than initially thought. Several voltage regulators are different and the capabilities of the sdcard and emmc also differ. Deriving from the p212 is not convient anymore so the libretech is now derived from s905x definition directly. Fixes: cd84aff1d981

As there is no way to actually query the hardware for the current clock rate, now racalc_rate() just returns the last rate that was previously set. But if the rate was not set yet, we return the bogus rate of 1000Hz. The branch clocks have the same rate as their parent, so in this case we just
