clocksource/drivers/moxart: Replace panic by pr_err

2016-09-12T05:28:38Z

The clksrc-of code is supposed to catch the return code and fail gracefully. Don't panic on error, but print the error and exit with a relevant error code. Signed-off-by: Daniel Lezcano Acked-by: Joel Stanley

clocksource/drivers/moxart: Replace setup_irq by request_irq

2016-09-12T05:28:23Z

Save memory space and line of code by replacing setup_irq by request_irq. Signed-off-by: Daniel Lezcano Acked-by: Joel Stanley

clocksource/drivers/moxart: Add Aspeed support

2016-09-09T12:15:47Z

The Aspeed SoC has timer IP with a very similar register layout to the moxart timer. This patch adds support for the fourth and fifth gen aspeed SoCs, and has been tested on the ast2400 and ast2500. Signed-off-by: Joel Stanley Acked-by: Rob Herring Signed-off-by: Daniel Lezcano

clocksource/drivers/moxart: Use struct to hold state

2016-09-09T12:15:36Z

Add a struct moxart_timer to hold the driver state, including the irqaction and struct clock_event_device. Most importantly this holds values for enabling and disabling the timer, so future support can be added for devices that use different bits for enable/disable. In preparation for future hardware support we add a MOXART prefix to the existing values. Signed-off-by: Joel Stanley Signed-off-by: Daniel Lezcano

clocksource/drivers/moxart: Refactor enable/disable

2016-09-09T12:15:21Z

This patch abstracts the enable and disable register writes into their own functions in preparation for future changes to use SoC specific values for the writes. Signed-off-by: Joel Stanley Signed-off-by: Daniel Lezcano

clocksources: Switch back to the clksrc table

2016-06-28T08:19:35Z

All the clocksource drivers's init function are now converted to return an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the clksrc-of table. Let's convert back the names: - CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE - clksrc-of-ret => clksrc-of Signed-off-by: Daniel Lezcano For exynos_mct and samsung_pwm_timer: Acked-by: Krzysztof Kozlowski For arch/arc: Acked-by: Vineet Gupta For mediatek driver: Acked-by: Matthias Brugger For the Rockchip-part Acked-by: Heiko Stuebner For STi : Acked-by: Patrice Chotard For the mps2-timer.c and versatile.c changes: Acked-by: Liviu Dudau For the OXNAS part : Acked-by: Neil Armstrong For LPC32xx driver: Acked-by: Sylvain Lemieux For Broadcom Kona timer change: Acked-by: Ray Jui For Sun4i and Sun5i: Acked-by: Chen-Yu Tsai For Meson6: Acked-by: Carlo Caione For Keystone: Acked-by: Santosh Shilimkar For NPS: Acked-by: Noam Camus For bcm2835: Acked-by: Eric Anholt

clocksource/drivers/moxart: Convert init function to return error

2016-06-28T08:19:24Z

The init functions do not return any error. They behave as the following: - panic, thus leading to a kernel crash while another timer may work and make the system boot up correctly or - print an error and let the caller unaware if the state of the system Change that by converting the init functions to return an error conforming to the CLOCKSOURCE_OF_RET prototype. Proper error handling (rollback, errno value) will be changed later case by case, thus this change just return back an error or success in the init function. Signed-off-by: Daniel Lezcano

clockevents/drivers/moxart: Migrate to new 'set-state' interface

2015-08-10T09:40:32Z

Migrate moxart driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. Cc: Jonas Jensen Signed-off-by: Viresh Kumar Signed-off-by: Daniel Lezcano

ARM: clocksource: moxart: Add bitops.h include

ARM: clocksource: Add support for MOXA ART SoCs

2013-07-18T13:27:47Z

This patch adds an clocksource driver for the main timer(s) found on MOXA ART SoCs. The MOXA ART SoC provides three separate timers with individual count/load/match registers, two are used here: TIMER1: clockevents, used to support oneshot and periodic events TIMER2: set up as a free running counter, used as clocksource Timers are preconfigured by bootloader to count down and interrupt on match or zero. Count increments every APB clock cycle and is automatically reloaded when it reaches zero. Signed-off-by: Jonas Jensen Signed-off-by: Daniel Lezcano
