2016-06-28clocksources: Switch back to the clksrc tableDaniel Lezcano
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 <daniel.lezcano@linaro.org> For exynos_mct and samsung_pwm_timer: Acked-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> For arch/arc: Acked-by: Vineet Gupta <vgupta@synopsys.com> For mediatek driver: Acked-by: Matthias Brugger <matthias.bgg@gmail.com> For the Rockchip-part Acked-by: Heiko Stuebner <heiko@sntech.de> For STi : Acked-by: Patrice Chotard <patrice.chotard@st.com> For the mps2-timer.c and versatile.c changes: Acked-by: Liviu Dudau <Liviu.Dudau@arm.com> For the OXNAS part : Acked-by: Neil Armstrong <narmstrong@baylibre.com> For LPC32xx driver: Acked-by: Sylvain Lemieux <slemieux.tyco@gmail.com> For Broadcom Kona timer change: Acked-by: Ray Jui <ray.jui@broadcom.com> For Sun4i and Sun5i: Acked-by: Chen-Yu Tsai <wens@csie.org> For Meson6: Acked-by: Carlo Caione <carlo@caione.org> For Keystone: Acked-by: Santosh Shilimkar <ssantosh@kernel.org> For NPS: Acked-by: Noam Camus <noamca@mellanox.com> For bcm2835: Acked-by: Eric Anholt <eric@anholt.net>
2016-06-28clocksource/drivers/tango_xtal: Convert init function to return errorDaniel Lezcano
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 leave the caller unaware of 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 returns an error code from the init function.

2016-04-22clocksource/drivers/tango-xtal: Fix boot hang due to incorrect testDaniel Lezcano
Commit 0881841f7e78 introduced a regression by inverting a test check after calling clocksource_mmio_init(). That results on the system to hang at boot time. Fix it by inverting the test again. Fixes: 0881841f7e78 ("Replace code by clocksource_mmio_init") Reported-by: Marc Gonzalez <marc_gonzalez@sigmadesigns.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2015-12-15clocksource/drivers/tango-xtal: Replace code by clocksource_mmio_initDaniel Lezcano
The current code to initialize, register and read the clocksource is already factored out in mmio.c via the clocksource_mmio_init function. Factor out the code with the clocksource_mmio_init function. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>

Sigma Designs Tango platforms provide a 27 MHz crystal oscillator. Use it for clocksource, sched_clock, and delay_timer. Signed-off-by: Marc Gonzalez <marc_gonzalez@sigmadesigns.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
