This patch adds a clocksource/clockevent driver for the timer found on some models in the TI-Nspire calculator series. The timer has two 16bit subtimers within its memory mapped I/O interface but only the first can generate interrupts. The first subtimer is used to generate clockevents but only if an interrupt number and register is given. The interrupt acknowledgement mechanism is a little strange because the interrupt mask and acknowledge registers are located in another memory mapped I/O peripheral. The address of this register is passed to the driver through device tree bindings. The second subtimer is used as a clocksource because it isn't capable of generating an interrupt. This subtimer is always added. Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Daniel Tang <dt.tangr@gmail.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> |
